大豆是世界上最重要的油料作物之一,也是豆制食品加工业的重要原料。解析大豆产量和品质调控的遗传机制和关键基因,对于通过分子设计育种培育高产优质大豆新品种具有重要意义。大豆产量和品质相关农艺性状大部分是复杂性状,受一因多效和遗传连锁的影响,性状间呈现耦合性相关。挖掘协同调控产量和品质相关性状的关键基因和解析重要农艺性状耦合的遗传网络,可以为培育高产优质大豆品种提供重要理论基础。以往的研究往往针对大豆单...
A pangenome aims to capture the complete genetic diversity within a species and reduce bias in genetic analysis inherent in using a single reference genome. However, the current linear format of most...
High seedling vigor can improve the ability to compete against weeds and flooding at the seedling stage and is essential for the direct seeding of rice. Early shoot length is an important performance ...
上海市农业科学院作物育种栽培研究所玉米研究中心郑洪建团队在Plant Molecular Biology Reporter发表了题为“Genome-wide Comparative Analysis of Genetic Diversity of Regular and Specialty Maize Germplasms through Genotyping by Target Sequenci...
近日,上海市农业科学院作物育种栽培研究所水稻中心,利用代谢组学和转录组学联合分析技术,对水稻巨胚高营养形成的分子机制展开研究,揭示了能量代谢,氨基酸代谢和脂质代谢是水稻巨胚发育早期成熟阶段的关键代谢通路,该研究有助于推动高营养水稻品种的育种。相关研究成果在线发表于国际学术期刊《Frontiers in Plant Science》(IF:5.753,二区TOP)上。
一个全面和通用的基于python的工具包,集成了特征提取、聚类、归一化、选择、降维、预测器构建、最佳描述符/模型选择、集成学习和DNA、RNA和蛋白质序列结果可视化的功能。用户只需要上传自己的数据集,并从中计算出自己需要的功能,所有必要的程序和优化设置都由软件自动完成。iLearn包括DNA、RNA和蛋白质的各种描述符,支持四种特征输出格式,以便于直接使用输出或与其他计算工具通信。总的来说,iLe...
ATBS1 INTERACTING FACTORs (AIFs)基因是一类bHLH蛋白,在植物生长发育过程中起着重要作用。本研究在亚洲棉、雷蒙德氏棉、陆地棉和海岛棉中分别鉴定得到8, 11, 16和15 AIFs。在该家族基因启动子中发现了多个与生长发育、胁迫和激素相关的启动元件。转录组数据显示该家族基因在棉花的花器官和纤维中高量表达。荧光定量表明该家族基因在纤维起始阶段高量表达。激素处理显示该家...
本研究在sGK9708×0-153、LMY22×LY343、鲁绵研28×新陆早24等多个重组自交系群体中通过综合考评表型变异和共有置信区间筛选主效QTL,结果表明在A04、A07、A08和D08染色体上存在重要的纤维品质相关QTL。其中,通过SGK9708×0-153群体的转录组数据在纤维长度和强度QTL中分别检测到50和48个候选基因。这些基因的共表达网络模块在多个RIL群体中的基因对之间表现出...
Salt stress is an important factor that limits rice yield. We identified a novel, strongly salt tolerant rice landrace called Changmaogu (CMG) collected from a coastal beach of Zhanjiang, Guangdong Pr...
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...
Cadmium (Cd) accumulation in rice followed by transfer to the food chain causes severe health problems in humans. Breeding of low Cd accumulation varieties is one of the most economical ways to solve ...
The crop suitability is the process of assessing the appropriateness or ability of a given type of land on the basis of growing conditions of a particular crop. The study focused on the crop suitabili...
Temporal monitoring of crop types is essential for the sustainable management of agricultural activities on both national and global levels. As a practical and efficient tool, remote sensing is widely...
Remote sensing technology has become an important method to rapidly acquireing of planting layout and composition of regional crops.It is very important to accurately master the planting area of Chine...
Land suitability analysis and preparing land use maps is one of the most beneficial applications of the Geographic Information System (GIS) in planning and managing land recourses. The main objective ...
