ABSTRACT
italic>Tussilago farfara L. is a perennial herb of Tussilago genus in the Compositae family. Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.
ABSTRACT
Ten compounds were isolated from the 95% ethanol extract of the whole plant of Gerbera piloselloides by silica gel column chromatography, MCI column chromatography and semi-preparative HPLC methods. Their structures were identified on the basis of physicochemical properties, spectral data (UV, IR, MS and NMR), circular dichroism (CD) spectra and single crystal X-ray diffraction analysis as 3′R-gerpilosecoumarin A (1a), 3′S-gerpilosecoumarin A (1b), gymnastone (2), gerberinside (3), divaricataester C (4), luteolin (5), caffeic acid methyl ester (6), ethyl chlorogenate (7), 6-(β-D-glucopyranosyloxy)-7-methoxy-5-benzoranpropanoic acid methyl ester (8) and glucozaluzanin C (9). Among them, new compounds 1a and 1b were new compounds and optical enantiomers, which were obtained by chiral resolution, and their absolute configurations were determined by quantum chemical calculation ECD. Compounds 1 and 1a/1b significantly increased the survival of IEC-6 in rat small intestinal crypt epithelial cells after LPS injury.
ABSTRACT
Abstract: An overview of insect galls on Asteraceae in Brazil is presented. We used the Web of Science database to find publications about insect galls from 1988 to 2020. We analyzed 88 publications and collected data from 51 of those. A total of 487 gall morphotypes were counted on 157 plant species of 42 genera. This value singled out Asteraceae as the richest plant family in number of gall morphotypes in Brazil. Most morphotypes were recorded in the Atlantic Forest (41%) and Cerrado (30.5%), the most surveyed biomes in Brazil. Baccharis L. supported the greatest gall richness (43.9%), which could be explained by the hypotheses of geographic area and taxon size. Baccharis concinna G.M. Barroso, B. dracunculifolia DC. and B. platypoda DC. were indicated as superhost species. Most galls were induced on stems (52.2%), a pattern known in Asteraceae for gall-inducing Tephritidae and Chloropidae, and extended in the present study to Cecidomyiidae. Most galls were fusiform (42.5%), which can be related to the highest number of gall on stems. Cecidomyiidae (Diptera) were the most frequent inducers, as observed worldwide. The presence of other dwellers - parasitoids, cecidophages, kleptoparasites, and successors - were reported in 8.8% of the gall morphotypes, being parasitoids the most frequent, as found in other Brazilian publications. Most host plants (58%) are endemic to Brazil, 14% are useful and few are vulnerable or endangered (six and four species, respectively). Due to the high host specificity, the gall-inducers associated with these plants can also be considered either endemic, important, vulnerable and/or endangered, respectively.
Resumo: Um panorama geral das galhas de insetos em Asteraceae no Brasil é apresentado. Usamos a base de dados "Web of Science" para encontrar publicações sobre galhas de insetos de 1988 a 2020. Analisamos 88 publicações no total, porém obtivemos dados de apenas 51. Um total de 487 morfotipos de galhas foi contabilizado em 157 espécies de plantas de 42 gêneros. Este valor indica as Asteraceae como a família botânica mais rica em número de morfotipos de galhas no Brasil. A maioria dos morfotipos foi registrada na Mata Atlântica (41%) e no Cerrado (30.5%), biomas mais investigados no Brasil. Baccharis L. suportou a maior riqueza de galhas (43.9%), o que poderia ser explicado pelas hipóteses de área geográfica e tamanho do táxon. Baccharis concinna G.M. Barroso, B. dracunculifolia DC. E B. platypoda DC. foram indicadas como as espécies super hospedeiras. A maioria das galhas foi induzida em caules (52.2%), um padrão conhecido em Asteraceae para Tephritidae e Chloropidae indutores de galhas, e estendido no presente estudo para Cecidomyiidae. A maioria das galhas foi fusiforme (42.5%), o que pode estar relacionado ao maior número de galhas em caule. Os Cecidomyiidae (Diptera) foram os indutores mais frequentes, como no mundo inteiro. A presença de outros ocupantes - parasitoides, cecidófagos, cleptoparasitas e sucessores - foi assinalada em 8.8% dos morfotipos de galhas, sendo os parasitoides os mais frequentes, como em outras publicações no país. A maioria das plantas hospedeiras são endêmicas do Brasil (58%), 14 são úteis e algumas são vulneráveis ou ameaçadas (seis e quatro, respectivamente). Devido à alta especificidade de plantas hospedeiras, os indutores de galhas associados a estas plantas podem ser considerados endêmicos, de importância econômica, vulneráveis e/ou ameaçados, respectivamente.

Abstract Vegetative aerial organs are considerably more exposed to environmental conditions and can reflect the specific adaptations of plants to their local environment. Aldama grandiflora species are known to be widely distributed in Brazil; therefore, individuals from different populations of this species are thought to be exposed to different abiotic and biotic conditions. Several anatomical studies conducted on Brazilian Aldama species have mainly focused on the qualitative anatomical characters or traits of these species, but not on their quantitative traits. In this study, we evaluated whether climate and soil conditions can change the morphometry among individuals of A. grandiflora collected from six sites in the Goiás State, Brazil, by assessing their anatomical characters. Further, soil sampling was performed, and climate data were collected from all the six sites. The analysis indicated few statistical differences among the populations evaluated, showing that A. grandiflora presented consistent leaf and stem anatomical characteristics. The small morpho-anatomical differences found among individuals of the different populations evaluated, reflected the soil conditions in which these populations were grown. Therefore, environmental factors have a significant influence on the morpho-anatomy of Aldama grandiflora.
Resumo Os órgãos vegetativos aéreos estão consideravelmente mais expostos às condições ambientais e podem refletir as adaptações específicas das plantas ao seu habitat. A espécie Aldama grandiflora é amplamente distribuída no Brasil e, dessa forma, indivíduos de diferentes populações podem estar expostos a diferentes condições ambientais. Vários estudos anatômicos realizados com espécies brasileiras do gênero Aldama têm abordado, principalmente, as características anatômicas qualitativas dessas espécies, mas não em suas características quantitativas. Neste estudo avaliamos se as condições climáticas e do solo podem alterar a morfometria entre os indivíduos de A. grandiflora coletados em seis populações do Estado de Goiás. Foram avaliados os caracteres anatômicos foliares e caulinares, além da amostragem do solo e coleta de dados climáticos, para os seis locais. A análise indicou algumas diferenças estatísticas entre as populações avaliadas, mostrando que A. grandiflora apresentou características anatômicas foliares e caulinares bastante consistentes. As pequenas diferenças morfo-anatômicas encontradas entre indivíduos das diferentes populações avaliadas, refletiram as condições do solo nos quais essas populações se desenvolveram. Assim sendo, fatores ambientais relacionados ao clima e condições do solo têm uma influência significativa sobre a morfo-anatomia de Aldama grandiflora.
