 ===Function===
-Please input function information here.
+* The phytohormone ethylene is a key signaling molecule that regulates a variety of developmental processes and stress responses in plants. Transcriptional modulation is a pivotal process controlling ethylene synthesis, which further triggers the expression of stress-related genes and plant adaptation to stresses.
-OsAP2-39 classes in rice APETALA-2 transcription factor, an AP2 domain containing a key control between ABA and GA interaction. Interactions between plant hormones is an important mechanism for regulating plant growth and development, analysis of these interactions is the key to improve yields and improved crop resistance to environmental stress. OsAP2-39 is abundantly expressed in anthers, booting the early roots also expressed. OsAP2-39 overexpression can cause phenotypic changes in transgenic rice variety, such as plant height reduction of 55%, 75% reduction of tillers, leaf number decreased by 74% heading delayed 1-2 weeks, more sensitive to dehydration, and ultimately due to biological and reducing the amount of grain number resulted in yields.. Controlling the expression level of OsAP2-39 which includes an APETALA 2 (AP2) domain leads to phenotypic changes in rice. Overexpression of OsAP2-39 leads to a reduction in yield by decreasing the biomass and the number of seeds in the transgenic rice lines. Global transcriptome analysis of the OsAP2-39 overexpression transgenic rice revealed the upregulation of a key Abscisic Acid (ABA) biosynthetic gene OsNCED-I which codes for 9-cis-epoxycarotenoid dioxygenase and leads to an increase in the endogenous ABA level. In addition to OsNCED-1, the gene expression analysis revealed the upregulation of a gene that codes for the Elongation of Upper most Internode (EUI) protein, an enzyme that catalyzes 16α, 17-epoxidation of non-13-hydroxylated GAs, which has been shown to deactivate gibberellins (GAs) in rice. The exogenous application of GA restores the wild-type phenotype in the transgenic line and ABA application induces the expression of EUI and suppresses the expression of OsAP2-39 in the wild-type line. These observations clarify the antagonistic relationship between ABA and GA and illustrate a mechanism that leads to homeostasis of these hormones. In vivo and in vitro analysis showed that the expression of both OsNCED-1 and EUI are directly controlled by OsAP2-39. Together, these results reveal a novel mechanism for the control of the ABA/GA balance in rice which is regulated by OsAP2-39 that in turn regulates plant growth and seed production.
