On salt stress PLETHORA signalling maintains root meristems
Salinity represses plant root growth, resulting in reduced biomass of agricultural plants. Little is known about how plants maintain root growth and development to counteract salt stress. SOS2-mediated PLT1/2 phosphorylation stabilizes PLT1/2, which is critical for root apical meristem maintenance under salt stress. Overall design: Comparative gene expression profiling analysis of RNA-seq data for gl1 and sos2-2 mutant.
