BACKGROUND: @entity7655 (CA) has been widely applied in medicine and food preservation. However, whether and how CA regulates plant physiology is largely unknown. To address these gaps, the present study investigated the beneficial effect of CA on root branching and its possible biochemical mechanism. RESULTS: The @entity614 ( @entity614 ) formation of pepper seedlings could be markedly induced by CA at specific concentrations without any inhibitory effect on primary root (PR) growth. CA could induce the generation of endogenous @entity3957 ( @entity3958 ) by increasing the activity of @entity462 desulfhydrase in roots. By fluorescently tracking endogenous @entity3958 in situ, it could be clearly observed that @entity3958 accumulated in the outer layer cells of the PR where LRs emerge. @entity8835 ( @entity3958 donor) treatment induced @entity614 formation, while @entity37405 ( @entity3958 scavenger) showed an adverse effect. The addition of @entity37405 mitigated the CA-induced increase in endogenous @entity3958 level, which in turn counteracted the inducible effect of CA on @entity614 formation. CONCLUSION: CA showed great potential in promoting @entity614 formation, which was mediated by endogenous @entity3958 . These results not only shed new light on the application of CA in agriculture but also extend the knowledge of @entity3958 signaling in the regulation of root branching.    2015 Society of Chemical Industry.
