From tetraploid to diploid, a pangenomic approach to identify genes lost during synthetic diploidization of Eragrostis curvula.

Introduction: In Eragrostis curvula, commonly known as weeping lovegrass, a synthetic diploidization event of the facultative apomictic tetraploid Tanganyika INTA cv. originated from the sexual diploid Victoria cv. Apomixis is an asexual reproduction by seeds in which the progeny is genetically identical to the maternal plant. Methods: To assess the genomic changes related to ploidy and to the reproductive mode occurring during diploidization, a mapping approach was followed to obtain the first E. curvula pangenome assembly. In this way, gDNA of Tanganyika INTA was extracted and sequenced in 2x250 Illumina pair-end reads and mapped against the Victoria genome assembly. The unmapped reads were used for variant calling, while the mapped reads were assembled using Masurca software. Results: The length of the assembly was 28,982,419 bp distributed in 18,032 contigs, and the variable genes annotated in these contigs rendered 3,952 gene models. Functional annotation of the genes showed that the reproductive pathway was differentially enriched. PCR amplification in gDNA and cDNA of Tanganyika INTA and Victoria was conducted to validate the presence/absence variation in five genes related to reproduction and ploidy. The polyploid nature of the Tanganyika INTA genome was also evaluated through the variant calling analysis showing the single nucleotide polymorphism (SNP) coverage and allele frequency distribution with a segmental allotetraploid pairing behavior. Discussion: The results presented here suggest that the genes were lost in Tanganyika INTA during the diploidization process that was conducted to suppress the apomictic pathway, affecting severely the fertility of Victoria cv.

A combined transcriptome - miRNAome approach revealed that a kinesin gene is differentially targeted by a novel miRNA in an apomictic genotype of Eragrostis curvula.

Weeping lovegrass (Eragrostis curvula [Shrad.] Nees) is a perennial grass typically established in semi-arid regions, with good adaptability to dry conditions and sandy soils. This polymorphic complex includes both sexual and apomictic cytotypes, with different ploidy levels (2x-8x). Diploids are known to be sexual, while most polyploids are facultative apomicts, and full apomicts have also been reported. Plant breeding studies throughout the years have focused on achieving the introgression of apomixis into species of agricultural relevance, but, given the complexity of the trait, a deeper understanding of the molecular basis of regulatory mechanisms of apomixis is still required. Apomixis is thought to be associated with silencing or disruption of the sexual pathway, and studies have shown it is influenced by epigenetic mechanisms. In a previous study, we explored the role of miRNA-mRNA interactions using two contrasting E. curvula phenotypes. Here, the sexual OTA-S, the facultative Don Walter and the obligate apomictic Tanganyika cDNA and sRNA libraries were inquired, searching for miRNA discovery and miRNA expression regulation of genes related to the reproductive mode. This allowed for the characterization of seven miRNAs and the validation of their miRNA-target interactions. Interestingly, a kinesin gene was found to be repressed in the apomictic cultivar Tanganyika, targeted by a novel miRNA that was found to be overexpressed in this genotype, suggestive of an involvement in the reproductive mode expression. Our work provided additional evidence of the contribution of the epigenetic regulation of the apomictic pathway.

Eragrostis curvula, a Model Species for Diplosporous Apomixis.

Eragrostis curvula (Schrad.) Ness is a grass with a particular apomictic embryo sac development called Eragrostis type. Apomixis is a type of asexual reproduction that produces seeds without fertilization in which the resulting progeny is genetically identical to the mother plant and with the potential to fix the hybrid vigour from more than one generation, among other advantages. The absence of meiosis and the occurrence of only two rounds of mitosis instead of three during embryo sac development make this model unique and suitable to be transferred to economically important crops. Throughout this review, we highlight the advances in the knowledge of apomixis in E. curvula using different techniques such as cytoembryology, DNA methylation analyses, small-RNA-seq, RNA-seq, genome assembly, and genotyping by sequencing. The main bulk of evidence points out that apomixis is inherited as a single Mendelian factor, and it is regulated by genetic and epigenetic mechanisms controlled by a complex network. With all this information, we propose a model of the mechanisms involved in diplosporous apomixis in this grass. All the genetic and epigenetic resources generated in E. curvula to study the reproductive mode changed its status from an orphan to a well-characterised species.

Genes Modulating the Increase in Sexuality in the Facultative Diplosporous Grass Eragrostis curvula under Water Stress Conditions.

Eragrostis curvula presents mainly facultative genotypes that reproduce by diplosporous apomixis, retaining a percentage of sexual pistils that increase under drought and other stressful situations, indicating that some regulators activated by stress could be affecting the apomixis/sexual switch. Water stress experiments were performed in order to associate the increase in sexual embryo sacs with the differential expression of genes in a facultative apomictic cultivar using cytoembryology and RNA sequencing. The percentage of sexual embryo sacs increased from 4 to 24% and 501 out of the 201,011 transcripts were differentially expressed (DE) between control and stressed plants. DE transcripts were compared with previous transcriptomes where apomictic and sexual genotypes were contrasted. The results point as candidates to transcripts related to methylation, ubiquitination, hormone and signal transduction pathways, transcription regulation and cell wall biosynthesis, some acting as a general response to stress and some that are specific to the reproductive mode. We suggest that a DNA glycosylase EcROS1-like could be demethylating, thus de-repressing a gene or genes involved in the sexuality pathways. Many of the other DE transcripts could be part of a complex mechanism that regulates apomixis and sexuality in this grass, the ones in the intersection between control/stress and apo/sex being the strongest candidates.

Characterization and discovery of miRNA and miRNA targets from apomictic and sexual genotypes of Eragrostis curvula.

BACKGROUND: Weeping lovegrass (Eragrostis curvula [Shrad.] Nees) is a perennial grass found in semi-arid regions that is well adapted for growth in sandy soils and drought conditions. E. curvula constitutes a polymorphic complex that includes cytotypes with different ploidy levels (from 2x to 8x), where most polyploids are facultative apomicts, although both sexual reproduction and full apomixis have been reported in this species. Apomixis is thought to be associated with silencing of the sexual pathway, which would involve epigenetic mechanisms. However, a correlation between small RNAs and apomixis has not yet been conclusively established. RESULTS: Aiming to contribute to the elucidation of their role in the expression of apomixis, we constructed small RNA libraries from sexual and apomictic E. curvula genotypes via Illumina technology, characterized the small RNA populations, and conducted differential expression analysis by comparing these small RNAs with the E. curvula reference transcriptome. We found that the expression of two genes is repressed in the sexual genotype, which is associated with specific microRNA expression. CONCLUSION: Our results support the hypothesis that in E. curvula the expression of apomixis leads to sexual repression.

Envarsus, una novedad para los nefrólogos del trasplante: estudio observacional retrospectivo / Envarsus, a novelty for transplant nephrologists: Observational retrospective study

El objetivo del presente estudio fue evaluar las concentraciones valle (Cpvalle) y la pauta posológica de tacrolimus tras la conversión de Prograf o Advagraf a Envarsus (nueva forma farmacéutica con tecnología Meltdose que mejora la absorción de fármacos liposolubles) en pacientes con trasplante renal estable, y su función renal. Se seleccionaron los pacientes trasplantados renales estables que fueron convertidos a Envarsus. Se definieron dos periodos: basal y conversión (Envarsus), y se estratificaron en función de la forma farmacéutica utilizada en el periodo basal. Se incluyeron 61 pacientes (24 con Advagraf y 37 con Prograf), con una edad media de 52 años. El tiempo medio postrasplante en el momento de la conversión a Envarsus fue de 76,3 meses y el seguimiento medio en el periodo basal y conversión fue de 10,1 y 11,6 meses, respectivamente. En el grupo Prograf y Envarsus las medianas Cpvalle fueron 6,6 vs 6,4 ng/ml (p = 0,636), con una dosis diaria media que disminuyó significativamente de 3 a 2 mg (p < 0,001), respectivamente, manteniendo el filtrado renal. Las medianas Cpvalle en los grupos Advagraf y Envarsus fueron 5,7 y 6,3 ng/ml (p = 0,07), con una mediana de dosis diaria de 7 y 4 mg (p < 0,001), respectivamente, e igual función renal. En pacientes trasplantados renales estables la conversión de Advagraf a Envarsus ha permitido reducir la dosis de tacrolimus un 42,9% y la de Prograf un 33,3% para mantener unas Cpvalle similares, sin que se altere la función renal

The aim of this study was to evaluate the trough concentrations (Cptrough) and the tacrolimus dosage regimen after the conversion of Prograf or Advagraf to Envarsus (new pharmaceutical form with MeltDose technology that improves the absorption of fat-soluble drugs) in patients with stable renal transplantation, and their renal function. We selected stable renal transplant patients who were converted to Envarsus. Two periods were defined: Baseline and Conversion (Envarsus) and they were stratified according to the pharmaceutical form used in the Baseline period. Sixty-one patients were included (24 with Advagraf and 37 with Prograf), with an average age of 52 years. The mean post-transplant time at the time of conversion to Envarsus was 76.3 months and the mean follow-up in the Baseline and Conversion period was 10.1 months and 11.6 months, respectively. In the Prograf and Envarsus group, the Cptrough medians were 6.6 vs 6.4 ng/mL (P = .636), with a mean daily dose that decreased significantly from 3 mg to 2 mg (P < .001), respectively, maintaining the filtration rate. The median Cptrough values in the Advagraf and Envarsus groups were 5.7 ng/mL and 6.3 ng/mL (P=.07), with a median daily dose of 7 mg and 4 mg (P<.001), respectively, and the same renal function. In stable renal transplant patients, the conversion from Advagraf to Envarsus has allowed the dose of tacrolimus to be reduced by 42.9% and, in the case of Prograf, by 33.3%, maintaining similar Cptrough values, without renal function being altered

A High-Density Linkage Map of the Forage Grass Eragrostis curvula and Localization of the Diplospory Locus.

Eragrostis curvula (Schrad.) Nees (weeping lovegrass) is an apomictic species native to Southern Africa that is used as forage grass in semiarid regions of Argentina. Apomixis is a mechanism for clonal propagation through seeds that involves the avoidance of meiosis to generate an unreduced embryo sac (apomeiosis), parthenogenesis, and viable endosperm formation in a fertilization-dependent or -independent manner. Here, we constructed the first saturated linkage map of tetraploid E. curvula using both traditional (AFLP and SSR) and high-throughput molecular markers (GBS-SNP) and identified the locus controlling diplospory. We also identified putative regulatory regions affecting the expressivity of this trait and syntenic relationships with genomes of other grass species. We obtained a tetraploid mapping population from a cross between a full sexual genotype (OTA-S) with a facultative apomictic individual of cv. Don Walter. Phenotypic characterization of F1 hybrids by cytoembryological analysis yielded a 1:1 ratio of apomictic vs. sexual plants (34:27, X 2 = 0.37), which agrees with the model of inheritance of a single dominant genetic factor. The final number of markers was 1,114 for OTA-S and 2,019 for Don Walter. These markers were distributed into 40 linkage groups per parental genotype, which is consistent with the number of E. curvula chromosomes (containing 2 to 123 markers per linkage group). The total length of the OTA-S map was 1,335 cM, with an average marker density of 1.22 cM per marker. The Don Walter map was 1,976.2 cM, with an average marker density of 0.98 cM/marker. The locus responsible for diplospory was mapped on Don Walter linkage group 3, with other 65 markers. QTL analyses of the expressivity of diplospory in the F1 hybrids revealed the presence of two main QTLs, located 3.27 and 15 cM from the diplospory locus. Both QTLs explained 28.6% of phenotypic variation. Syntenic analysis allowed us to establish the groups of homologs/homeologs for each linkage map. The genetic linkage map reported in this study, the first such map for E. curvula, is the most saturated map for the genus Eragrostis and one of the most saturated maps for a polyploid forage grass species.

De novo transcriptome sequencing and assembly from apomictic and sexual Eragrostis curvula genotypes.

A long-standing goal in plant breeding has been the ability to confer apomixis to agriculturally relevant species, which would require a deeper comprehension of the molecular basis of apomictic regulatory mechanisms. Eragrostis curvula (Schrad.) Nees is a perennial grass that includes both sexual and apomictic cytotypes. The availability of a reference transcriptome for this species would constitute a very important tool toward the identification of genes controlling key steps of the apomictic pathway. Here, we used Roche/454 sequencing technologies to generate reads from inflorescences of E. curvula apomictic and sexual genotypes that were de novo assembled into a reference transcriptome. Near 90% of the 49568 assembled isotigs showed sequence similarity to sequences deposited in the public databases. A gene ontology analysis categorized 27448 isotigs into at least one of the three main GO categories. We identified 11475 SSRs, and several of them were assayed in E curvula germoplasm using SSR-based primers, providing a valuable set of molecular markers that could allow direct allele selection. The differential contribution to each library of the spliced forms of several transcripts revealed the existence of several isotigs produced via alternative splicing of single genes. The reference transcriptome presented and validated in this work will be useful for the identification of a wide range of gene(s) related to agronomic traits of E. curvula, including those controlling key steps of the apomictic pathway in this species, allowing the extrapolation of the findings to other plant species.

Apomixis frequency under stress conditions in weeping lovegrass (Eragrostis curvula).

To overcome environmental stress, plants develop physiological responses that are triggered by genetic or epigenetic changes, some of which involve DNA methylation. It has been proposed that apomixis, the formation of asexual seeds without meiosis, occurs through the temporal or spatial deregulation of the sexual process mediated by genetic and epigenetic factors influenced by the environment. Here, we explored whether there was a link between the occurrence of apomixis and various factors that generate stress, including drought stress, in vitro culture, and intraspecific hybridization. For this purpose, we monitored the embryo sacs of different weeping lovegrass (Eragrostis curvula [Schrad.] Nees) genotypes after the plants were subjected to these stress conditions. Progeny tests based on molecular markers and genome methylation status were analyzed following the stress treatment. When grown in the greenhouse, the cultivar Tanganyika INTA generated less than 2% of its progeny by sexual reproduction. Plants of this cultivar subjected to different stresses showed an increase of sexual embryo sacs, demonstrating an increased expression of sexuality compared to control plants. Plants of the cv. Tanganyika USDA did not demonstrate the ability to generate sexual embryo sacs under any conditions and is therefore classified as a fully apomictic cultivar. We found that this change in the prevalence of sexuality was correlated with genetic and epigenetic changes analyzed by MSAP and AFLPs profiles. Our results demonstrate that different stress conditions can alter the expression of sexual reproduction in facultative tetraploid apomictic cultivars and when the stress stops the reproductive mode shift back to the apomixis original level. These data together with previous observations allow us to generate a hypothetical model of the regulation of apomixis in weeping lovegrass in which the genetic/s region/s that condition apomixis, is/are affected by ploidy, and is/are subjected to epigenetic control.

Older adults' memory for medical information, effect of number and mode of presentation: An experimental study.

OBJECTIVE: To analyze different ways of presenting medical information to older adults, tailoring the information and its presentation to the characteristics of memory function in old age. METHODS: Experimental study. We took into account the following variables: amount of information, type of information and mode of presentation, and time delay. RESULTS: The greater the number of recommendations, the lower the recall; visual presentation does not enhance verbal presentation; lifestyle information is recalled better than medication information; after ten minutes the percentage of memory decreases significantly; the first and last recommendations are better remembered. CONCLUSION: As a whole, these findings show that older adults remember more medical information when very few recommendations are provided in each session. PRACTICE IMPLICATIONS: It is inadvisable to overload older adults with a large amount of information: It is better to program more consultations and provide less information.

El reconocimiento de emociones en caras como indicador de depresión subclínica en jóvenes y ancianos: Un estudio preliminar / Emotion recognition in faces as an indicator of subclinical depression in young and elderly people: A preliminary study

El reconocimiento de emociones en las caras desempeña un papel muy importante en la comunicación humana y en la interacción social. Este trabajo pretende estudiar si es posible detectar a través del reconocimiento de emociones en caras los síntomas de depresión, y si esa posibilidad es idéntica en jóvenes y en ancianos. Para ello se evaluó a dos grupos de participantes, uno con síntomas subclínicos de depresión y otro control, utilizando la tarea de reconocimiento de emociones en caras del MSCEIT. El principal hallazgo de este trabajo es que el reconocimiento de una emoción positiva en una cara neutra está relacionado con el nivel de sintomatología depresiva, sobre todo en el grupo de personas mayores de 60 años. Estos resultados van en la línea del “efecto de congruencia del afecto” pues los participantes del grupo de síntomas bajos de depresión valoran más positivamente una cara neutra, al menos en lo que al entusiasmo se refiere. En resumen, este estudio pre-liminar aporta datos de cómo el reconocimiento de emociones en caras puede ser un indicador de la depresión subclínica, sobre todo en personas mayores

Facial emotion recognition plays an important role in human communication and social interaction. This study aims to analyze the possibility of detecting depressive symptoms through facial recognition of emotions and if this possibility is similar in young and elderly people. Two groups of participants were assessed: one with subclinical symptoms of depression, and the control group. The MSCEIT facial emotion recognition task was ad-ministered to both groups. The main result is that there is an association between the recognition of a positive emotion in a neutral face and the level of depressive symptomatology, especially for people over 60 years old. This result is consistent with the mood congruent effect: participants with few depressive symptoms evaluate a neutral face in a more positive way, at least in terms of enthusiasm. In summary, this preliminary study provides data on how facial emotion recognition could be an indicator of subclinical depression, especially in the elderly

Life review therapy using autobiographical retrieval practice for older adults with clinical depression / Terapia de revisión de vida mediante la recuperación de recuerdos autobiográficos en adultos mayores con depresión clínica

The aim of this experiment was to examine the efficacy of life review based on autobiographical retrieval practice for treating depression in older adults. Thirty-seven clinically depressed older adults aged 64-83, who were also receiving pharmacological treatment, were randomly assigned to life review therapy or to a placebo condition with supportive therapy. Results indicated decreased depression for both conditions, with no significant differences between the two therapies. There was some indication of greater gain in production of specific memories among those in life review therapy. Patients who produced higher numbers of specific memories decreased their depression scores at a faster rate (AU)
