Diatoms are widely applied in the ecological status assessment of aquatic ecosystems using indices calculated from pollution sensitivity and indicator values species. Traditional, morphology-based identification species requires in-depth taxonomic knowledge expertise. Identifying taxa according to their barcode sequences obtained with high-throughput sequencing (metabarcoding) would be a promis...

The large and economically important genus Solanum contains ca. 1,400 species distributed worldwide. One of the 12–14 major clades identified in the genus is the Leptostemonum clade, or the “spiny solanums.” Previous molecular phylogenetic studies have identified 14 major clades in the spiny solanums. Among these is the Carolinense clade, which contains Solanum carolinense, the type species of ...

Rehmannia is a non-parasitic genus in Orobanchaceae including six species mainly distributed in central and north China. Its phylogenetic position and infrageneric relationships remain uncertain due to potential hybridization and polyploidization. In this study, we sequenced and compared the complete chloroplast genomes of six Rehmannia species using Illumina sequencing technology to elucidate ...

Eragrostis is a large genus in subfamily Chloridoideae of Poaceae. Recent phylogenetic analyses have suggested that the genus may not be monophyletic, that some of its segregate genera may be better placed within Eragrostis, and that current infrageneric classifications may not represent monophyletic groups. We have used molecular sequence data from the plastid locus rps16 and the nuclear gene ...

Imperata is a ubiquitous grass genus of the tribe Andropogoneae (Poaceae), distributed throughout world. Previous systematic studies had established that encompasses nine species although no phylogenetic molecular are available in which all taxa have been included. The American continent has largest number species, encouraging research into how these evolved. Here we present analysis based on t...

Plantago is a cosmopolitan genus with approximately 200 species and various infrageneric classifications have been reported. In this study, the seed morphologies of 19 from Iran were studied documented in detail using scanning electron microscopy light microscopy. The grouped by statistical analyses such as minimum spherical cluster method based on Euclidean distance, principal coordinate analy...
