Acts to suppress chlorophyll degradation under moisture stress. Expressed in seed (PubMed:8479424). Highest expression in leaves and guard cells (PubMed:25333723). Expressed during the early and middle stages of seed development (PubMed:8479424). Abundant throughout plant development in the aerial part of the plant (PubMed:25333723). Up-regulated by dehydration, salt stress and abscisic acid (ABA). Not regulated by cold. The BURP domain located at the C-terminus has not been identified in non-plant proteins. Enhanced drought tolerance. Truncated N-terminus. Truncated N-terminus.
