  • Os01g0797600 <=> AP37, OsAP37, OsERF3, OsERF#075, OsERF075, OsERF75, ERF75, AP2/EREBP#004, AP2/EREBP4, OsBIERF2, BIERF2


  • AP37 (Os01g0797600), is AP2 domain-containing protein, it is found to be significantly up-regulated in both genotypes under cold stress.[1]
  • AP37 gene has the potential to improve drought tolerance in rice without causing undesirable growth phenotypes.


  • The overexpression of AP37 and AP59 in rice under the control of the constitutive promoter OsCc1 increased the tolerance to drought and high salinity at the vegetative stage.
  • Increased tolerance to low temperatures was observed only in OsCc1:AP37 plants. More importantly, the OsCc1:AP37 plants showed significantly enhanced drought tolerance in the field, which increased grain yield by 16% to 57% over controls under severe drought conditions, yet exhibited no significant difference under normal growth conditions.
  • In contrast, grain yield in OsCc1:AP59 plants in the field was reduced by 23% to 43% compared with controls under both normal and drought stress conditions.
  • Microarray experiments identified 10 and 38 genes that are up-regulated by AP37 and AP59, respectively, in addition to 37 genes that are commonly induced by both factors.
