盐害是制约全世界作物生长的主要非生物胁迫之一,全球有6%土地和20%灌溉用地受到盐害影响,严重制约了农作物生长发育和产量。水稻作为全球主要粮食作物之一,对盐胁迫敏感。盐胁迫条件下,水稻种子萌发和幼苗形态建成显著受抑制,严重制约了我国水稻直播的推广和盐碱地区耕地利用。因此,挖掘鉴定控制水稻种子萌发的关键基因,阐明其在盐胁迫条件下调控种子活力的分子机制,对培育适合盐碱地生长的种子高活力耐盐水稻品种和保...
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...
Multiplex CRISPR-Cas9-based genome editing is an efficient method for targeted disruption of gene function in plants. Use of CRISPR-Cas9 has increased rapidly in recent years and is becoming a routine...
团队全面系统论述了植物激素脱落酸(ABA)在种子的成熟、休眠和萌发过程中的最新研究进展,总结了脱落酸通过含量变化和信号转导的调节来参与种子发育不同阶段的分子机制,提出了脱落酸与其他不同的激素、代谢物质等信号分子互作调控种子发育的模式图,对于揭示脱落酸介导的种子发育过程的分子调控网络具有重要意义。
A new cycle of seed grants from the Mario Einaudi Center for International Studies will help faculty from six colleges across Cornell tackle issues ranging from the health of endangered wild dogs to t...
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。
NF-YCs are important transcription factors with diverse functions in the plant kingdoms including seed development. NF-YC8, 9, 10, 11 and 12 are close homologs with similar seed-specific expression pa...
4-5.Comprehensive Technology of F1 Hybrid Rice Seed Production.
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。
Seed vigour significantly influences the seed production and plant regeneration performance. The capability of NIR spectroscopy to identify seed vigour across multiple tree species rapidly and cost-ef...
Fertilization Independent Endosperm(FIE) is an essential member of Polycomb Repressive Complex 2(PRC2) that plays important roles in the developmental regulation of plants. OsFIE1 and OsFIE2 are two F...
Why are there so many species of plants? Why do some plants thrive, while others don't?Ecologist Noelle Beckman of Utah State University and her colleagues explore these questions in new fin...
Calanthe tsoongianaT. Tang et F.T. Wang, a terrestrial orchid that is endemic to China, has become rare and endangered due to limited natural reproduction and habitat destruction. There is an urgent n...
The creation of canopy gaps is thought to be an efficient silvicultural operation to diversify species composition of monoculture conifer plantations; however, the shortage of regeneration materials i...
Plant annexins are proteins with various functions, such as binding calcium ions and negatively charging lipids. Although their importance in plant stress responses has been widely reported, their fun...
