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

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...
中籼杂交水稻亲本多态性的AFLP分析Polymorphisms in Semilate indica Hybrid Rice as Revealed by AFLPs
中籼杂交稻 AFLP 遗传距离
2007/12/29
对15个籼型杂交水稻亲本进行AFLP分析，结果表明：亲本间遗传距离小，在0.0589~0.3305之间，平均为0.2033。15个亲本按类平均法可聚为两类，Ⅰ类为不育系，Ⅱ类为恢复系。其中Ⅱ类又分为两个亚类，Ⅱ-1不含明恢63血缘、Ⅱ-2全部含明恢63血缘。Ⅰ/Ⅱ-1与Ⅰ/Ⅱ-2间的遗传距离无明显差异，揭示恢复系的遗传基础较一致，这可能是当前的品种不能超过汕优63的重要原因之一。要提高水稻的杂种优...
