Development of submergence-tolerant rice cultivars: the Sub1 locus and beyond.
BACKGROUND AND AIMS Submergence is a recurring problem in the rice-producing rainfed lowlands of south and south-east Asia. Developing rice cultivars with tolerance of submergence and with agronomic and quality traits acceptable to farmers is a feasible approach to address this problem. The objectives of this study were to (a) develop mega varieties with Sub1 introgression that are submergence ...
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 variable cluster of ethylene response factor-like genes regulates metabolic and developmental acclimation responses to submergence in rice.
Submergence-1 (Sub1), a major quantitative trait locus affecting tolerance to complete submergence in lowland rice (Oryza sativa), contains two or three ethylene response factor (ERF)-like genes whose transcripts are regulated by submergence. In the submergence-intolerant japonica cultivar M202, this locus encodes two ERF genes, Sub1B and Sub1C. In the tolerant near-isogenic line containing the...
