Where whole‐genome duplication is most beneficial: Adaptation of mangroves to a wide salinity range between land and sea

Shaohua Xu, Zixiao Guo, Xiao Feng, Shao Shao, more

Molecular Ecology > 32 > 2 > 460 - 475

Whole‐genome duplication (WGD) is believed to increase the chance of adaptation to a new environment. This conjecture may apply particularly well to new environments that are not only different but also more variable than ancestral habitats. One such prominent environment is the interface between land and sea, which has been invaded by woody plants, collectively referred as mangroves, multiple times...
