Contributes to the initial phase of responses to abiotic and biotic stress signals (Probable). Binds FYPP3 and facilitates FYPP3 degradation to promote abscisic acid (ABA) response (PubMed:29175650). Interacts with CRY2 in the cytoplasm (PubMed:28633330). Interacts with Verticillium dahliae PevD1 (PubMed:28633330). Interacts with FYPP3 (PubMed:29175650). Highly expressed in sensecent leaves, cauline leaves and sepals (PubMed:21277785). Expressed in the shoot apical meristem, leaf veins, central cylinder, root hair zone, root tips, rosette leaves, flowers and siliques (PubMed:21277785). Induced by touch and salt stress (PubMed:16533544, PubMed:21277785). Induced by wounding, calcium, magnesium and methyl jasmonate (PubMed:16533544). Induced by osmotic stress, cycloheximide and ozone (PubMed:21277785). Induced by abscisic acid (ABA) (PubMed:29175650). Reduced length of primary root and increased sensitivity to salt stress. Truncated N-terminus.
