Description
Yuejia Liu and seven colleagues catalogue, in a 2026 genome study, a family of gene switches in wild jujube, a hardy tree valued in dry regions of China. The R2R3-MYB family helps plants grow and answer environmental stress, yet its membership in this species was unmapped.
Ninety-one family genes were found scattered unevenly across twelve chromosomes, mostly switched on in leaves. Family growth came mainly from segmental duplication under conservative selection. Thirteen genes tied directly to water shortage responses and to the drought hormone abscisic acid. Four genes, ZjMYB5, ZjMYB53, ZjMYB57, and ZjMYB85, emerged as core drought responders with tissue- and time-specific patterns, offering breeding targets.
