Non-canonical WOX11-mediated root branching contributes to plasticity in Arabidopsis root system architecture

Abstract: Lateral roots (LRs), which originate from the growing root, and adventitious roots (ARs), which are formed from non-root organs, are the main contributors to the post-embryonic root system in Arabidopsis. However, our knowledge of how formation of the root system is altered in response to diverse inductive cues is limited. Here, we show that WOX11 contributes to root system plasticity. When seedlings are grown vertically on medium, WOX11 is not expressed in LR founder cells. During AR initiation, WOX11 is expr… Show more

“…During the AR formation from Arabidopsis leaf explants cultured on medium without added hormones, auxin promotes the fate transition of the regeneration‐competent cell near the wounded site to the AR founder cell by upregulating the expression of WUSCHEL‐RELATED HOMEOBOX11 ( WOX11 ) and the partially redundant WOX12 . WOX11 and 12 along with auxin upregulate the expression of LATERAL ORGAN BOUNDARIES DOMAIN16 ( LBD16 ) to initiate the AR primordium (Liu et al , Sheng et al , Xu ). Therefore, AR formation from leaf explants is via the WOX11 ‐mediated pathway.…”
