摘要
Plants may initiate adventitious root growth from non-root organs (Bellini et al., 2014; Druege et al., 2019). In Arabidopsis thaliana, adventitious roots form either from hypocotyls, contributing to the root system architecture, or from wounded organs during regeneration (Bellini et al., 2014; Xu, 2018). Jasmonate (JA), a wound-induced hormone, regulates adventitious rooting from hypocotyls and wounded organs. Interestingly, JA plays opposite adventitious rooting-associated regulatory roles at different stages and from different sources through crosstalk with multiple hormones. In this issue of the Journal of Experimental Botany, Dob et al. (2021) show that the crosstalk between JA and cytokinin regulates adventitious rooting from hypocotyls.
