OsNRAMP2 facilitates Cd efflux from vacuoles and contributes to the difference in grain Cd accumulation between japonica and indica rice
Rice (Oryza sativa L.) Cadmium OsNRAMP2 Haplotype
2023/4/21
Cadmium (Cd) accumulation in rice grain is of health concern. Identifying genes involved in grain Cd accumulation and performing molecular breeding may reduce it. In this study, knockout of OsNRAMP2, ...
Global Transcriptome and Co-Expression Network Analysis Reveal Contrasting Response of Japonica and Indica Rice Cultivar to γ Radiation
gamma irradiation gene network morphology rice (Oryza sativa L.) transcriptomic analysis
2023/8/9
Japonica and indica are two important subspecies in cultivated Asian rice. Irradiation is a classical approach to induce mutations and create novel germplasm. However, little is known about the differ...
The qSAC3 locus from indica rice effectively increases amylose content under a variety of conditions
Amylose content Chromosome segment substitution lines Environmental effect Quantitative trait loci Rice quality
2023/8/9
Amylose content (AC) is a critical factor for the quality of rice. It is determined by the biosynthesis gene Waxy (Wx) and a variety of quantitative trait loci (QTLs). Although many QTLs have been rep...
The effect of different antibiotics on the elimination of Agrobacterium and high frequency Agrobacterium-mediated transformation of indica rice (Oryza sativa L.)
Agrobacterium-mediated transformation Agrobacterium elimination gus reporter gene hygromycin phosphotransferase selectable marker gene (hpt) rice
2014/2/25
We report here the suitable explant with high efficiency of transformation and the positive effects of timentin over other antibiotics like carbenicillin and cefotaxime on the elimination of Agrobacte...
Varietal Difference in Leaf Senescence during Ripening Period of Advanced Indica Rice
Indica rice Leaf senescence Nitrogen Oryza sativa L.
2009/8/6
The study has been carried out to evaluate varietal difference in leaf senescence during the ripening period in relation to sink size and nitrogen application. Leaf senescence was early in the medium...
Characteristics for the Efficiency of Spikelet Production and the Ripening in High-Yielding Japonica-Incdica Hybrid and Semidwarf Indica Rice Varieties
Efficiency of spikelet production High-yielding ability Japonica-indica hybrid rice Japonica rice Percentage of ripened grains
2009/8/6
Three high-yielding japonica-indica hybrid (JIH) and semidwarf indica (SDI) rice varieties, and ten japonica (J) rice varieties, including different plant types, were cultivated under sparse (30×30 cm...
Effect of Panicle Size on Grain Yield of IRRI-Released Indica Rice Cultivars in the Wet Season
Grain yield Panicle size Solar radiation Rice Wet season
2009/7/29
Grain yield under wet season (WS) conditions has gradually received more attention due to looming scarcity of irrigation water, which limits the area for planting to flooded lowland rice in the dry se...
The Effect of the Amount of Nitrogen Fertilizer on Starch Metabolism in Leaf Sheath of Japonica and Indica Rice Varieties during the Heading Period
ADP-glucose pyrophosphorylase Debranching enzyme Indica rice Japonica rice Leaf sheath Nitrogen fertilizer Starch Starch branching enzyme
2009/7/24
The effects of the amount of nitrogen fertilizer on the starch metabolism of rice leaf sheath during the heading period in the japonica rice variety, cv. Nipponbare were compared with those in the ind...
