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 کاملInheritance of Submergence Tolerance in Lowland Rice Variety
About 70% of the rain-fed lowland rice farms in Nigeria are prone to seasonal flooding, which is a major constraint to rice production in some major rice producing areas. Each year that there is flooding, rice farmers in these parts of the country lose their entire crop. This research focuses on developing a submergence tolerant rice variety to overcome crop loss due to flooding. A study of the...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولStudies on some biomarkers for submergence tolerance in rice cultivars. Sidhartha Banerjee and Malay Kumar Adak*
In the present study, three rice varieties namely Swarna, Swarna Sub1A, and FR13A were evaluated on the basis of their antioxidative responses to screen submergence tolerance capabilities. Fourteen-day- old seedlings were completely submerged for 7 days and were observed to have a significant variation in reactive oxygen species like H2O2 and O2-. The variety Swarna recorded maximum accumulatio...
