Rice is the most important cereal crop governing food security in Asia. Reliable and regular information on the area under rice production is the basis of policy decisions related to imports, export...
A receptor-like protein RMC is involved in regulation of iron acquisition in rice
Fe concentration iron defiiency OsRMC rice (Oryza sativa) root system seed Fe concentration
<
2015/2/5
Iron (Fe) is one of the essential mineral elements for plant growth and development. Acquisition of Fe by plants is mediated by a complex network involving Fe mobilization, uptake by root cells, and t...
Physiological mechanisms underlying OsNAC5-dependent tolerance of rice plants to abiotic stress

2015/2/5
To understand the functions of transcription factor OsNAC5 in response to abiotic stress, we generated transgenic rice plants with knockdown OsNAC5 by RNAinterfered (RNAi) and overexpressing OsNAC5, a...
以接触力学为基础，建立了脱粒元件与稻谷对心碰撞时压缩位移和最大压力分布模型。针对不同含水率时稻谷塑性、脆性力学性质的差异，得出了稻谷与脱粒元件冲击损伤临界速度计算公式。对钉齿与镇稻10号、武香粳14、淮稻9号、镇糯653和协优084稻谷冲击损伤临界速度进行了实例计算，在试验台架上进行了实测，试验均值与理论计算基本一致。
Genetical Studies on Germination of Seed and Seedling Establishment for Breeding of Improved Rice Varieties Suitable for Direct Seeding Culture
