水稻起源于热带和亚热带,对低温十分敏感,当温度低于15℃时水稻便无法正常生长。有统计显示,每年低温冷害导致我国水稻减产约50亿kg。近年来,因直播稻大面积推广以及水稻种植区域不断由热带、亚热带向高海拔、高纬度地区扩张,水稻遭受低温冷害的频率有增加趋势。低温冷害已成为限制我国水稻生产的一大瓶颈。因此,挖掘调控水稻耐冷性的关键基因,研究其作用机理,对防控水稻低温冷害具有重要意义。
2024年1月4日下午,第90期创新沙龙“A Diversity and regional variation of endosymbiosis in Myzus persicae and Rhopalosiphum padi”主题分享会在植保楼2060A会议室举行。本次分享会的嘉宾是澳大利亚墨尔本大学生物科学学院的杨琼副研究员,共有五十余名师生参会,现场气氛热烈。
India being an agrarian nation widely depends upon rainfall for its agricultural productivity. The failure of rainfall and hence shortfall of productivity badly affects national economy. With an intri...
Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.Man...
An unspoken frustration for evolutionary biologists over the past 100 years, says Craig Albertson at the University of Massachusetts Amherst, is that genetics can only account for a small percentage o...
Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood.
Most species are negatively affected when humans transform natural habitats into urban areas and agricultural lands, but a few species actually benefit from these activities. These species — called hu...
This study investigates variation in collective behavior in a natural population of colonies of the harvester ant, Pogonomyrmex barbatus. Harvester ant colonies regulate foraging activity to adjust t...
Protection mutualisms mediate trophic interactions in many systems, but their effects on the surrounding community are rarely studied. Ant-plant symbioses are classic examples of protection mutual...
We analysed relationships between demersal fish species richness, environment and trawl characteristics using an extensive collection of trawl data from the oceans around New Zealand. Analyses were ca...
Genetic variation in three Croatian coldblood horse populations was analysed using a sequence analysis of the proximal part (nt 15 498?5 821) of the D-loop region of mtDNA. Twenty unrelated horses wer...
A new Iowa State University study focusing on insulin signaling uncovered surprising genetic diversity across reptiles, birds and mammals.The research sets the stage for an improved understanding of m...

Understanding variation among users’ information needs and the quality of information in an electronic system is important for informaticians to ensure data are fit-for-use in answering important ques...
How effectively plants utilize nitrogen (N), the most limiting nutrient in natural ecosystems, will largely determine the success of plants in intra- and inter-specific competition. Theory suggests th...
