Physiological basis of tolerance to complete submergence in rice involves genetic factors in addition to the SUB1 gene
Recurring floods in Asia cause poor crop establishment. Yields decline drastically when plants are completely submerged for a few days. Traditional rice cultivars predominate because they have acquired moderate tolerance to flooding but they carry the penalty of inherently lower grain yields. In contrast, modern high-yielding varieties are highly susceptible to flooding. Cultivars with toleranc...
متن کاملPhysiological and molecular basis of susceptibility and tolerance of rice plants to complete submergence.
Rice plants are much damaged by several days of total submergence. The effect can be a serious problem for rice farmers in the rainfed lowlands of Asia, and runs contrary to a widespread belief amongst plant biologists that rice is highly tolerant of submergence. This article assesses the characteristics of the underwater environment that may damage rice plants, examines various physiological m...
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...
