Genbank accession number
- Key message
- Natural variants in HAN1 diverged between indica and japonica rice during domestication
- Natural variation in the HAN1 gene confers chilling tolerance in rice and allowed adaptation to a temperate climate.
- A specific allele from temperate japonica rice, which gained a putative MYB cis-element in the promoter of HAN1 during the divergence of the two japonica ecotypes, enhances the chilling tolerance of temperate japonica rice and allows it to adapt to a temperate climate
- HAN1 encodes an oxidase that catalyzes the conversion of biologically active jasmonoyl-L-isoleucine (JA-Ile) to the inactive form 12-hydroxy-JA-Ile (12OH-JA-Ile) and fine-tunes the JA-mediated chilling response
- Connection
- HAN1, OsANN1, Calcium binding protein OsANN1 regulates rice blast disease resistance by inactivating jasmonic acid signaling., By yeast two-hybrid screening, we found that OsANN1 interacted with a cytochrome P450 monooxygenase, HAN1 ("HAN" termed "chilling" in Chinese), which has been reported to catalyze the conversion of biologically active jasmonoyl-L-isoleucine (JA-Ile) to the inactive form 12-hydroxy-JA-Ile (12OH-JA-Ile)
- HAN1, OsANN1, Calcium binding protein OsANN1 regulates rice blast disease resistance by inactivating jasmonic acid signaling., Genetic evidence showed that OsANN1 acts upstream of HAN1
- HAN1, OsANN1, Calcium binding protein OsANN1 regulates rice blast disease resistance by inactivating jasmonic acid signaling., OsANN1 stabilizes HAN1 in planta, resulting in the inactivation of the endogenous biologically active JA-Ile
