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 کاملThe submergence tolerance regulator Sub1A mediates stress-responsive expression of AP2/ERF transcription factors.
We previously characterized the rice (Oryza sativa) Submergence1 (Sub1) locus encoding three ethylene-responsive factor (ERF) transcriptional regulators. Genotypes carrying the Sub1A-1 allele are tolerant of prolonged submergence. To elucidate the mechanism of Sub1A-1-mediated tolerance, we performed transcriptome analyses comparing the temporal submergence response of Sub1A-1-containing tolera...
متن کاملThe submergence tolerance gene SUB1A delays leaf senescence under prolonged darkness through hormonal regulation in rice.
Leaf senescence is a natural age-dependent process that is induced prematurely by various environmental stresses. Typical alterations during leaf senescence include breakdown of chlorophyll, a shift to catabolism of energy reserves, and induction of senescence-associated genes, all of which can occur during submergence, drought, and constant darkness. Here, we evaluated the influence of the sub...
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...
