Rapidly Evolving Genes and Stress Adaptation of Two Desert Poplars, Populus euphratica and P. pruinosa
Understanding which genes have evolved rapidly with the recent tree speciation in arid habitats can provide valuable insights into different adaptation mechanisms. We employed a comparative evolutionary analysis of expressed sequence tags (ESTs) from two desert poplars, Populus pruinosa and P. euphratica, which diverged in the recent past. Following an approach taken previously with P. euphrati...
متن کاملGenetic Differentiation and Delimitation between Ecologically Diverged Populus euphratica and P. pruinosa
BACKGROUND The fixed genetic differences between ecologically divergent species were found to change greatly depending on the markers examined. With such species it is difficult to differentiate between shared ancestral polymorphisms and past introgressions between the diverging species. In order to disentangle these possibilities and provide a further case for DNA barcoding of plants, we exami...
متن کاملDistinct patterns of natural selection in Na+/H+ antiporter genes in Populus euphratica and Populus pruinosa
Salt tolerance genes constitute an important class of loci in plant genomes. Little is known about the extent to which natural selection in saline environments has acted upon these loci, and what types of nucleotide diversity such selection has given rise to. Here, we surveyed genetic diversity in three types of Na+/H+ antiporter gene (SOS, NhaD, and NHX, belonging to the cation/proton antiport...
متن کاملThe draft genome sequence of a desert tree Populus pruinosa
Populus pruinosa is a large tree that grows in deserts and shows distinct differences in both morphology and adaptation compared to its sister species, P. euphratica. Here we present a draft genome sequence for P. pruinosa and examine genomic variations between the 2 species. A total of 60 Gb of clean reads from whole-genome sequencing of a P. pruinosa individual were generated using the Illumi...
متن کاملTissue-Specific Transcriptome Analysis Reveals Multiple Responses to Salt Stress in Populus euphratica Seedlings
Salt stress is one of the most crucial factors impacting plant growth, development and reproduction. However, information regarding differences in tissue-specific gene expression patterns, which may improve a plant's tolerance to salt stress, is limited. Here, we investigated the gene expression patterns in tissues of Populus euphratica Oliv. seedlings using RNA sequencing (RNA-Seq) technology....
