From signaling to function: how strigolactones regulate plant development

摘要

Strigolactones (SLs) are a class of plant hormones first discovered based on their ability to stimulate germination of the root parasite witchweed (Striga lutea Lour.) and regulate symbiosis between arbuscular mycorrhiza fungi and their host plants. Recent studies have identified diverse functions of SLs in shoot branching, leaf development, root architecture, and the responses to environment stress (GomezRoldan et al., 2008;Umehara et al., 2008;Brewer et al.,2013).
