Genes, Vol. 12, Pages 1635: ABA and Bud Dormancy in Perennials: Current Knowledge and Future Perspective Genes doi: 10.3390/genes12101635 Authors: Wenqiang Pan Jiahui Liang Juanjuan Sui Jingru Li Chang Liu Yin Xin Yanmin Zhang Shaokun Wang Yajie Zhao Jie Zhang Mingfang Yi Sonia Gazzarrini Jian Wu Bud dormancy is an evolved trait that confers adaptation to harsh environments, and affects flower differentiation, crop yield and vegetative growth in perennials. ABA is a stress hormone and a major regulator of dormancy. Although the physiology of bud dormancy is complex, several advancements have been achieved in this field recently by using genetics, omics and bioinformatics methods. Here, we review the current knowledge on the role of ABA and environmental signals, as well as the interplay of other hormones and sucrose, in the regulation of this process. We also discuss emerging potential mechanisms in this physiological process, including epigenetic regulation.
