Leaf rolling is one of the most significant symptoms of drought stress in plant. Previously, we identified a dominant negative mutant, termed  rolled and erect 1  (hereafter referred to  rel1-D ), regulating leaf rolling and erectness in rice. However, the role of  REL1  in drought response is still poorly understood. Here, our results indicated that  rel1 - D  displayed higher tolerance to drought relative to wild type, and the activity of superoxide dismutase (SOD) and drought responsive genes were significantly up-regulated in  rel1-D . Moreover, our results revealed that  rel1-D  was hypersensitive to ABA and the expression of ABA associated genes was significantly increased in  rel1-D , suggesting that  REL1  likely coordinates ABA to regulate drought response. Using the RNA-seq approach, we identified a large group of differentially expressed genes that regulate stimuli and stresses response. Consistently, we also found that constitutive expression of  REL1  alters the expression of biotic and abiotic stress responsive genes by the isobaric tags for relative and absolute quantification (iTRAQ) analysis. Integrative analysis demonstrated that 8 genes/proteins identified by both RNA-seq and iTRAQ would be the potential targets in term of the  REL1- mediated leaf morphology. Together, we proposed that leaf rolling and drought tolerance of  rel1-D  under normal condition might be caused by the endogenously perturbed homeostasis derived from continuous stressful dynamics.
