The submergence tolerance regulator SUB1A mediates crosstalk between submergence and drought tolerance in rice.
Submergence and drought are major constraints to rice (Oryza sativa) production in rain-fed farmlands, both of which can occur sequentially during a single crop cycle. SUB1A, an ERF transcription factor found in limited rice accessions, dampens ethylene production and gibberellic acid responsiveness during submergence, economizing carbohydrate reserves and significantly prolonging endurance. He...

متن کاملSubmergence tolerance in rice requires Sub1A, an ethylene-response-factor-like gene.
Submergence of rice (Oryza sativa) by flash flooding is a major constraint to rice production in Asia. Rice cultivars vary in their capacity to tolerate complete submergence; quantitative trait loci analyses have revealed that a large portion of this variation in submergence tolerance can be explained by one locus (Sub1) on chromosome 9. Two recently published papers (Takeshi Fukao et al. and K...
متن کاملEvolutionary analysis of the Sub1 gene cluster that confers submergence tolerance to domesticated rice.
BACKGROUND AND AIMS Tolerance of complete submergence is recognized in a small number of accessions of domesticated Asian rice (Oryza sativa) and can be conferred by the Sub1A-1 gene of the polygenic Submergence-1 (Sub1) locus. In all O. sativa varieties, the Sub1 locus encodes the ethylene-responsive factor (ERF) genes Sub1B and Sub1C. A third paralogous ERF gene, Sub1A, is limited to a subset...
متن کاملA homolog of ETHYLENE OVERPRODUCER, OsETOL1, differentially modulates drought and submergence tolerance in rice.
Submergence and drought are major limiting factors for crop production. However, very limited studies have been reported on the distinct or overlapping mechanisms of plants in response to the two water extremes. Here we report an ETHYLENE OVERPRODUCER 1-like gene (OsETOL1) that modulates differentially drought and submergence tolerance in rice (Oryza sativa L.). Two allelic mutants of OsETOL1 s...
