ABSTRACT
Most species of Helvella have been described from temperate regions in Asia, Europe, and North America, but little is known about the genus from tropical regions. In this report, phylogenetic analyses of 11 newly collected saddle-like fungi from northern Thailand using three genetic markers [the nuclear large subunit ribosomal DNA (LSU), the heat shock protein 90 (HSP90), and the translation elongation factor 1-alpha (TEF)] confirm their assignment in Helvella. Two species were described as new, i.e., Helvella atroides and H. orentitomentosa, and two species, i.e., H. fistulosa and H. rugosa, were reported for the first time in Thailand. Details of macro- and microscopic characters and illustrations were provided for each species. To date, seven species of Helvella have been recorded in Thailand, and a key for identifying the Thai Helvella species was provided here.
ABSTRACT
Rubus pinfaensis H. Lév. & Vaniot is of great importance in the phylogeny and evolution amongst Rosaceae, genus Rubus L. plants. The chloroplast genome of R. pinfaensis was reported in this study, which is 155,523 bp in size, with an average GC content of 37.13%. The complete chloroplast genome has a typical quadripartite structure, including a large single copy (LSC) region (85,211 bp) and a small single copy (SSC) region (18,718 bp), which were separated a pair of inverted repeats (IRs, 25,797 bp). This plastome contained 129 different genes (112 unique), including 85 protein-coding genes (79 unique), 36 tRNA genes (29 unique), and 8 rRNA genes (4 unique). The chloroplast genome of R. pinfaensis has completed that will be based on the phylogeny and genomic studies in the family Rosaceae, genus Rubus L.
ABSTRACT
During the investigation of lignicolous freshwater fungi in the Tibetan Plateau habitat, fifteen collections were isolated from submerged decaying wood. Fungal characteristics are commonly found as punctiform or powdery colonies with dark pigmented and muriform conidia. Multigene phylogenetic analyses of combined ITS, LSU, SSU and TEF DNA sequences showed that they belong to three families in Pleosporales. Among them, Paramonodictys dispersa, Pleopunctum megalosporum, Pl. multicellularum and Pl. rotundatum are established as new species. Paradictyoarthrinium hydei, Pleopunctum ellipsoideum and Pl. pseudoellipsoideum are reported as new records on the freshwater habitats in Tibetan Plateau, China. The morphological descriptions and illustrations of the new collections are provided.
ABSTRACT
Rubus lambertianus Ser. var. paykouangensis (Levl.) Hand.-Mazz. is great important in the phylogeny and evolution of the genus Rubus L. in the family Rosaceae. The chloroplast genome of R. lambertianus var. paykouangensis reported in this study is 156177 bp in length, and it has an average GC content of 37.18%. The complete chloroplast genome showed a typical quadripartite structure, comprising a small single copy (SSC) region (18,730 bp) and a large single copy (LSC) region (85,883 bp), both of which were separated by a pair of inverted repeats (IRs, 25,782 bp). This plastome was discovered to contain 129 different genes (112 unique), including 85 protein-coding genes (79 unique), 36 tRNA genes (29 unique), and 8 rRNA genes (4 unique). The published chloroplast genome of R. lambertianus var. paykouangensis will provide a significant insight into elucidating the phylogenetic relationship of taxa within the genus Rubus of the family Rosaceae.
ABSTRACT
Rubus ellipticus Sm. var. obcordatus Focke is an important species in the phylogeny and evolution of genus Rubus L. in the family Rosaceae. Its chloroplast genome, as reported in this study, is 155,656 bp in size, and it has an average GC content of 37.14%. The chloroplast genome showed a typical quadripartite structure comprising a large single copy (LSC) region (85,388 bp) and a small single copy (SSC) region (18,730 bp), which were separated by a pair of inverted repeats (IRs, 25,769 bp). In total, this plastome was found to contain 129 different genes, including 85 protein-coding genes, 36 tRNA genes, and eight rRNA genes. The completed chloroplast genome of R. ellipticus var. obcordatus will set a new insight into clarifying the phylogeny and genomic studies in genus Rubus of the family Rosaceae.
ABSTRACT
Rubus setchuenensis Bureau et Franch. is important in phylogeny and evolution amongst genus Rubus L. (Rosaceae) plants. The chloroplast genome of R. setchuenensis reported in this study is 156,231 bp in size, with an average GC content of 37.19%. The complete chloroplast genome has a typical quadripartite structure, including a large single copy (LSC) region (85,829 bp) and a small single copy (SSC) region (18,860 bp), which are separated by a pair of inverted repeats (IRs, 25,771 bp). This plastome contains 129 different genes, including 85 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The phylogenetic analysis of 20 chloroplast genomes from genera Fragaria, Rosa and Rubus of the family Rosaceae suggested that R. setchuenensis clustered into one clade with the other three species of section Malachobatus Focke, and then grouped with four species of section Idaeobatus Focke, while species from Fragaria and Rosa were classified into a group, separately.
ABSTRACT
Pterospermum menglunense is the endangered plant species of the genus Pterospermum in the family Sterculiaceae. In the study, the complete genome was 162,421bp in length, including of two inverted repeats (IRA and IRB, 25,572 bp), separated by a large single-copy region (LSC, 90,754 bp) and a small single-copy region (SSC, 20,523 bp). The genome annotation reveals a total of 132 genes, including 37 transfer RNA (tRNA) genes, 8 ribosomal RNA (rRNA) genes, and 87 protein-coding (PCG) genes. The phylogenetic tree showed P. menglunense is closely related to Pterospermum kingtungense.
