Mapping QTLs for Physiological Traits Associated with Drought Tolerance in Rice (Oryza Sativa L.)
Drought is the most important limiting factor for crop production and it is becoming an increasingly severe problem in many regions of the world [1]. According to FAO statistics, the percentage of drought affected land areas more than doubled from the 1970s to the early 2000s in the world [2]. Drought is a world-spread problem seriously influencing grain production and quality and with increasi...
متن کاملImproved Salt Tolerance and Morphological Variation in Indica Rice (Oryza sativa L.) Transformed with a Catalase Gene from E. coli
In an attempt to improve the salt tolerance of rice, we introduced katE, a catalase gene of Escherichia coli, into the indica rice cultivar Kasalath. Transformation was carried out using Agrobacterium tumefaciens strain EHA101 harboring a binary vector pIES6/Hm/katE which contains genes for catalase katE, hygromycine resistance gene HPT and kanamycin resistance gene NPTII in the T-DNA region. W...
متن کاملDrought-induced site-specific DNA methylation and its association with drought tolerance in rice (Oryza sativa L.)
An indica pyramiding line, DK151, and its recurrent parent, IR64, were evaluated under drought stress and non-stress conditions for three consecutive seasons. DK151 showed significantly improved tolerance to drought. The DNA methylation changes in DK151 and IR64 under drought stress and subsequent recovery were assessed using methylation-sensitive amplified polymorphism analysis. Our results in...
متن کاملHeterologous Expression of AtWRKY57 Confers Drought Tolerance in Oryza sativa
Drought stress is a severe environmental factor that greatly restricts plant distribution and crop production. Recently, we have found that overexpressing AtWRKY57 enhanced drought tolerance in Arabidopsis thaliana. In this study, we further reported that the Arabidopsis WRKY57 transcription factor was able to confer drought tolerance to transgenic rice (Oryza sativa) plants. The enhanced droug...
متن کاملEffects of cyanobacterial extracellular products and gibberellic acid on salinity tolerance in Oryza sativa L
Salt stress is one of the most serious factors limiting the productivity of rice, the staple diet in many countries. Gibberellic acid has been reported to reduce NaCl-induced growth inhibition in some plants including rice. Most paddy soils have a natural population of Cyanobacteria, prokaryotic photosynthethic microorganisms, which synthesize and liberate plant growth regulators such as gibber...
