Effects of nano-Fe3O4-modified biochar on iron plaque formation and Cd accumulation in rice (Oryza sativa L.).

Environmental Pollution, 2020
Nano-Fe3O4-modified biochar (BC-Fe) was prepared by the coprecipitation of nano-Fe3O4 on a rice husk biochar surface. The effects of BC-Fe on cadmium (Cd) bioavailability in soil and on Cd accumulation and translocation in rice (Oryza sativa L. cv.

Hydrogen peroxide modulates activity and expression of antioxidant enzymes and protects photosynthetic activity from arsenic damage in rice (Oryza sativa L.).

Journal of Hazardous Materials, 2020
We studied the role of H2O2 in the protection of photosynthesis from arsenic (As) damage in rice (Oryza sativa L.) by examining the antioxidant system, photosynthesis, and growth attributes.

Heterosis breeding in rice (Oryza sativa L.)

Theoretical and Applied Genetics, 1982
Studies conducted at the International Rice Research Institute (IRRI) during 1980 and 1981 have shown up to 73% heterosis, 59% heterobeltiosis and 34% standard heterosis for yield in rice. The latter was estimated in comparison to commercial varieties: IR36 and IR42 (yield 4-5 t/ha in wet season trials and 7-8 t/ha in dry season trials).

Rice, Indica (Oryza sativa L.)

2014
Indica varieties, which are generally recalcitrant to tissue culture and transformation, occupy 80 % of rice cultivation area in the world. Therefore, transformation method for indica rice must be improved greatly so that global rice production would take full advantage of cutting-edge biotechnology.

HETEROSIS IN RICE (Oryza sativa L.).

Madras Agricultural Journal, 1987
A study was made to assess the extent of oxploitable heterosis in a 7 x 7 diallel. The results indicated that almost all combinations involving IR 8 as one of the parents pos- sessed high mean and significant heterosis for yield but none of thec ombinations excelled it, indicating non-existence of exploitable heterosis with the parents under study ...

Effects of root morphology and anatomy on cadmium uptake and translocation in rice (Oryza sativa L.).

Journal of Environmental Science, 2019
A clear description of the certain mechanisms of cadmium (Cd) uptake and translocation in rice (Oryza sativa L.) may help to reduce Cd accumulation in rice grain. Hydroponic experiments were carried out to determine the effects of cultivation conditions (

Transcriptome and proteome analyses reveal selenium mediated amelioration of arsenic toxicity in rice (Oryza sativa L.).

Journal of Hazardous Materials, 2020
Arsenic (As), a chronic poison and non-threshold carcinogen, is a food chain contaminant in rice, posing yield losses as well as serious health risks. Selenium (Se), a trace element, is a known antagonist of As toxicity. In present study, RNA seq.

Characterization of the sulfurtransferase family from Oryza sativa L

Plant Physiology and Biochemistry, 2011
Sulfurtransferases (Str) comprise a group of enzymes widely distributed in archaea, eubacteria, and eukaryota which catalyze the transfer of a sulfur atom from suitable sulfur donors to nucleophilic sulfur acceptors. Neither the in vivo sulfur donors nor the acceptors of Str could be clearly identified in any of the organisms investigated so far.
