Abscisic acid signaling gates salt-specific responses of plant roots

Soil salinity presents a dual challenge for plants, involving both osmotic and ionic stress. In response, plants deploy distinct yet interconnected mechanisms to cope with these facets of salinity...

We show that salt activates LBD16 independent of auxin-ARF7/19: a ZAT6-dependent pathway enables root branching while the canonical pathway is inhibited by salt! @zhang_yanxia @KilianDuijts @PPH_WUR @dorota_kawa @vandijkadj @WURplant & many others biorxiv.org/content/10.1101/…

Root branching in salt requires auxin-independent modulation of LBD16 function

Salinity stress constrains lateral root (LR) growth and severely impacts plant growth. Auxin signaling is indispensable for the regulation of LR formation. Nevertheless, the molecular mechanism of...
