text ERF66 and ERF67, are directly transcriptionally up-regulated by SUB1A-1 under submergence and overexpression of ERF66 or ERF67 leads to activation of anaerobic survival genes and enhanced submergence tolerance (PMID: PMID: 30723146). Thus, ERF66, ERF67 and SUB1A-1 contribute to submergence tolerance using quiescence responses for survival during prolonged submergence. SUB1A-1 functions as a ?master regulator,? coordinating the quiescence responses. Not all rice varieties have SUB1A functional allele. the O. sativa japponica cultivars fo not have Sub1A gene and thus, this gene is abssent in the rice reference genome (RAP & MSU databasess). Submergence-intolerant cultivars, such as Swarna and IR64, lack SUB1A-1 or have the SUB1A-2 allele, which is inactive as a result of a point mutation within the coding region. Introgression or overexpression of SUB1A-1 into the Swarna and IR64 lines confers significant submergence tolerance.
