Complete plastid genome of , a critically endangered plant with extremely small populations (PSESP) from southwest China.

The complete plastid genome of , a critically endangered plant species with extremely small populations, was obtained using Illumina HiSeq X Ten and ONT PromethION sequencing. The full length of the plastid genome is 206,467 bp with an overall GC content of 35.8%, which encodes 118 unique genes, including 78 protein-coding genes, 36 tRNA and 4 rRNA genes.

Molecular Markers in Whole Genome Evolution of Brachypodium.

Molecular markers play more and more important role in population genetic and phylogenetic studies; choice of marker systems for a particular study has become a serious problem. These marker systems have different advantages and disadvantages, so it is imperative to keep in mind all the pros and cons of the technique while selecting one for the problem to be addressed.Here, we concisely introduced three molecular marker techniques, namely SSR, ISSR, and RFLP.

Natural selection on floral traits of (Ranunculaceae), an alpine perennial with generalized pollination system from Northwest Yunnan.

Floral traits, including those invisible to humans but visible to pollinators, that increase pollination efficiency may be selected by pollinators in plant species with pollen limitation of seed production, but the importance of pollinators as selective agents on different floral traits needs to be further quantified experimentally. In the present study, we examined selective strength on flower diameter, flower height, UV bulls-eye size, sepal size and UV proportion via female fitness in , based on open-pollinated and hand-pollinated flowers, through which pollinator-mediated selection was calculated for each of floral traits. Our results suggest that seed production of is pollen limited in natural conditions.
