to evaluate tolerance of rice genotypes (oryza sativa l.) to soil/water salinity and to utilize selected tolerant genotypes in rice breeding program and further agronomy and physilogical studies 56 rice genotypes have been evaluated. of which 40 rice genotypes from international rice research institute (irri) together with 16 selected tolerant rice genotypes have been tested in two separate exp...

A more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving conditions. The objectives of this study were to analyze the ...

Clostridium oryzae was originally isolated from the soil of a Japanese rice field. C. oryzae represents a novel species within the genus Clostridium and is associated with anaerobic rice straw degradation. Here, we present the draft genome sequence of C. oryzae DSM 28571 (5.076 Mbp), containing 4,590 predicted protein-coding genes.

the objectives of this study was to estimation of greenhouse gases (ghg) emissions and global warming in rice production and identify measures to reducing fossil energy use and greenhouse gases emissions. three rice production systems included sri, improved and conventional were studied. all activities, field operation and data in production methods and differents inputs rates were monitored an...

Stenotrophomonas maltophilia is an endophyte which plays important roles in agricultural production as a plant growth-promoting bacterium. Here, we present the draft genome sequence of strain RR-10, which was isolated from a rice root in a rice field of China.

Reduced fertilizer usage is one of the objectives of field management in the pursuit of sustainable agriculture. Here, we report on shifts of bacterial communities in paddy rice ecosystems with low (LN), standard (SN), and high (HN) levels of N fertilizer application (0, 30, and 300 kg N ha(-1), respectively). The LN field had received no N fertilizer for 5 years prior to the experiment. The LN...

T2A-1 is a newly developed transgenic rice that expresses a synthesized cry2Aa gene driven by the maize ubiquitin promoter. T2A-1 exhibits high resistance against lepidopteran pests of rice. The brown planthopper, Nilapavarta lugens (Stål), is a main nontarget sap-sucking insect pest of rice, and Cyrtorhinus lividipennis (Reuter) is the major predator of the eggs and young nymphs of planthopper...

Plant transgenic technology has been widely utilized for engineering crops for trait improvements and for production of high value proteins such as pharmaceuticals. However, the unintended spreading of commercial transgenic crops by pollination and seed dispersal is a major concern for environmental and food safety. Simple and reliable containment strategies for transgenes are highly desirable....
