Polyploidy is an important evolutionary mechanism in plants, and in some genera (e.g., Solidago in Asteraceae) it is particularly widespread and is hypothesized to have played a major role in diversification. Goldenrods are notorious for their ploidy variation, with roughly 14% and 32% of recognized North American species being polyploid or including multiple cytotypes, respectively. We used tr...

Although the monogenomic genera of the Triticeae have been analyzed in numerous biosystematic studies, the allopolyploid genera have not been as extensively studied within a phylogenetic framework. We focus on North American species of Elymus, which, under the current genomic system of classification, are almost all allotetraploid, combining the St genome of Pseudoroegneria with the H genome of...

calomyscus mystax is endemic to great balkhan mountains in southwestern turkmenistan. however there have been some inaccurate reports of existing this species in koprtdagh mts. and northern iran, but these were considered as calomyscus elburzensis and calomyscus grandis. phylogenetic analyses on cytb gene clustered samples from kopetdagh mts. in northeastern iran with one specimen of c. mystax ...

It is essential to identify and determine the properties of native plants as natural genetic resources. The present study was performed to identify the Mindium (Michauxi) laevigata species using molecular and biochemical procedures such as genomic DNA extraction, sequencing, and antioxidant capacity and protein content determination at both vegetative and generative phases in various parts of t...
