Understanding forest dynamics at the stand level is crucial for sustainable management. Landsat time series have been shown to be effective for identification of drastic changes, such as natural distu...
High-quality urban green space supports the healthy functioning of urban ecosystems. This study aimed to rapidly assess the distribution, and accurately estimate the above-ground biomass, of urban gre...
本研究对亲本海7124、中棉所36及47个子代纤维发育5,10和15天的转录组数据分析,鉴定到35420个表达基因,构建了纤维伸长相关动态表达调控网络,其中10366个表达基因在子代中产生新等位基因(ENAs);进一步鉴定到7个时空特异调控表达基因簇,差异表达分析筛选到105个候选基因,包含15个新等位基因。CRISPR-cas9系统敲除GhMAH1使纤维显著变短。本研究为解析陆海群体纤维长度变异...
种子后熟是种子成熟的延续过程,也是植物自动释放休眠的一种形式。种子后熟过程中往往存在一系列生理和分子变化。明确作物种子后熟过程中生理和分子变化规律,对破除种子休眠,提高种子质量,保证播种后田间种子萌发和幼苗的形成具有重要意义。
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...
Identification of the right parental combinations to maximize heterosis is the major goal of hybrid breeding, which could be achieved through identification of heterotic groups. The main objective of ...
Xyloglucan endotransglucosylase/hydrolase (XTH), belonging to glycoside hydrolase family 16, is one of the key enzymes in plant cell wall remodeling. Schima superba is an important timber and fireproo...
张红生教授团队在水稻种子活力调控分子机制和遗传网络解析研究方面取得重要进展,鉴定的两个种子活力调控关键基因显著提高水稻种子活力,在耐直播水稻新品种培育、水稻直播种植生产中有重要应用价值。
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。
Alcohol dehydrogenase (ADH) is a vital enzyme in the biosynthesis pathway of six-carbon volatiles in plants. However, little is known about its functions in tea plants. Here, we identified two ADH gen...
该研究以渗入了海岛棉基因组组分的优质种质鲁原343为亲本,构建了包含239个重组自交系的遗传作图群体,利用SLAF标签构建了高密度遗传图谱,结合7个环境的表型数据,共鉴定104个纤维品质和产量性状QTLs,其中66个QTL共定位于19个QTL簇中。该研究团队通过进一步对鲁原343进行全基因组深度测序,解析鲁原343的遗传组成及其对纤维相关性状的遗传贡献,发现来自G. hirsutum races(...
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...
Very little is known about saponins in tea and their biosynthesis in tea plants despite of theimportance. Here, we studied tea saponins and their biosynthesis genes. Saponins were promptly recovered i...
Weeds can be major environmental and economic burdens in New Zealand. Traditional methods of weed control include manual and chemical approaches can be time consuming and costly. Some chemical herbici...
To understand the genetic basis of nitrogen and phosphorus uptake in the cultivated rice, quantitative trait loci (QTL) analysis for 7 nitrogen and phosphorus uptake-related traits including above-gro...
