Genetic structure of Populus hybrid zone along the Irtysh River provides insight into plastid-nuclear incompatibility

Abstract: In plants, the maintenance of species integrity despite hybridization has often been explained by the co-adaption of nuclear gene complexes. However, the interaction between plastid and nuclear sub-genomes has been underestimated. Here, we analyzed the genetic structure of a Populus alba and P. tremula hybrid zone along the Irtysh River system in the Altai region, northwest China, using both nuclear microsatellites and plastid DNA sequences. We found high interspecific differentiation, although the hybrid P. ×… Show more

“…However, hybrids of the next generations and backcrosses are not always discarded by natural selection and can be quite abundant in populations (Hersch-Green et al, 2014;Roe et al, 2014;Chhatre et al, 2018). Numerous studies in hybridization zones showed that backcrossing between hybrid plants and those of parental species are common (Christe et al, 2016;Hu et al, 2016;Jiang et al, 2016;Zeng et al, 2016;Vasilyeva et al, 2018). Therefore, the observed hybridization is retrogressive, being accompanied by the gradual transfer of genetic material from one taxon to another across inter-species isolation barriers.…”
