Physiological Basis and Transcriptional Profiling of Three Salt-Tolerant Mutant Lines of Rice
Salinity is a complex trait that affects growth and productivity in many crops, including rice. Mutation induction, a useful tool to generate salt tolerant plants, enables the analysis of plants with similar genetic background, facilitating the understanding of the salt tolerance mechanisms. In this work, we generated three salt tolerant mutant lines by irradiation of a salt-sensitive cultivar ...
متن کاملGolden Indica and Japonica rice lines amenable to deregulation.
As an important step toward free access and, thus, impact of GoldenRice, a freedom-to-operate situation has been achieved for developing countries for the technology involved. Specifically, to carry the invention beyond its initial "proof-of-concept" status in a Japonica rice (Oryza sativa) cultivar, we report here on two transformed elite Indica varieties (IR64 and MTL250) plus one Japonica va...
متن کاملMarker-assisted Backcrossing for Identification of Salt Tolerant Rice Lines
SSR or microsatellite markers are proved to be ideal for making genetic maps, assisting selection and studying genetic diversity in germplasm. SSR markers are playing important role to identify gene for salt tolerance that can be helpful for plant breeders to develop new cultivars. The experiment was conducted during the period from July 2009 to November 2010 in the experimental field and Biote...
متن کاملGlycinebetaine alleviates water deficit stress in indica rice using proline accumulation, photosynthetic efficiencies, growth performances and yield attributes
We investigated the role of GlyBet (100 mM) applied exogenously in alleviating water-deficit induced stress in indica rice cv. Pathumthani 1 (PT1). Exogenous GlyBet increased proline concentration in the leaf tissues of water deficit stressed plants depend on a degree of soil water content (SWC), especially at severe water deficit (25% SWC). Foliar GlyBet (100 mM) significantly enhanced chlorop...
متن کاملEffect of indica pedigree on eating and cooking quality in rice backcross inbred lines of indica and japonica crosses
Amylopectin is one of the major determinants of rice (Oryza sativa L.) grain quality, and a large difference in amylopectin is found between two subspecies: japonica and indica. However, the relationship among rice grain quality, indica/japonica genetic background, and amylopectin has not been clearly established. In this study, a series of backcross inbred lines derived from the cross between ...
