Arabidopsis UBC32 enhances drought tolerance in rice. A, Drought tolerance test of WT (Nipponbare) and Ub:UBC32 transgenic plants (2# and 14#). B, Statistical analysis of the seedling survival rate in (A). Values represent the mean ± sd (four biological replicates; n = 48). Statistical significance was analyzed by one-way ANOVA (**P <0.01). C, A proposed working model for the role of UBC32 and Rma1 in the plant response to drought stress. Under drought stress, the expression of UBC32 and Rma1 is induced. UBC32 cooperates with Rma1 to recognize phosphorylated PIP2;1 and PIP2;2 and target them for ubiquitin-dependent degradation to enhance drought tolerance in plants. PM, plasma membrane.
