The unfolded protein response (UPR) mitigates stress caused by accumulation of unfolded proteins in the endoplasmic reticulum (ER). Inositol-requiring enzyme 1 (IRE1) is the most conserved sensor of the UPR with ribonuclease activity that mediates cytoplasmic splicing and decay of mRNA encoding secretory and membrane proteins. In the present study, we demonstrate that the Arabidopsis mutant defective in two IRE1 genes exhibit retarded growth of primary roots under moderate salt stress, although such grow retardation is not observed in wild type plants. Microscopic observation showed decrease in the number of meristematic cells in the mutant under salt stress. This finding suggests that IRE1 plays a role in the maintenance of root meristems under salt stress. Possible connections between the function of IRE1 and the salt sensitivity are discussed.
