盐碱胁迫影响水稻的生长发育、存活率与最终产量。水稻耐盐碱是由多基因控制的复杂性状。研究水稻应对盐碱胁迫的关键基因及其调控网络，对于培育耐盐碱水稻品种具有重要科学意义和应用价值。2023年6月16日，国际著名期刊Nature Communications发表了万建民院士团队在水稻耐盐碱研究上的新进展。
Genome-wide identification of NF-YA gene family in cotton and the positive role of GhNF-YA10 and GhNF-YA23 in salt tolerance
全基因组分析 雷蒙德氏棉 亚洲棉 海岛棉 陆地棉
2024/5/17
本研究基于全基因组分析，在雷蒙德氏棉、亚洲棉、海岛棉和陆地棉基因组中分别鉴定得到16、16、31和29个NF-YA基因。通过进化树分析将NF-YA基因分为4个亚组。结构分析表明NF-YA基因在棉属进化过程中相对保守。荧光定量显示GhNF-YAs可能通过ABA和 MeJA的调控通路响应盐和干旱。VIGS沉默GhNF-YA10和GhNF-YA23的表达，能显著降低棉花对盐的抗性，表明这两个基...
Salt marsh resilience compromised by crabs along tidal creek edges

Coastal marshes are vulnerable to erosion caused by rising seas, pounding waves, and tidal flows. In California's Elkhorn Slough, these vulnerabilities are made worse by superabundant crabs found at t...
近日，中国科学院物理研究所/北京凝聚态物理国家研究中心清洁能源重点实验室E01组岳金明博士生在索鎏敏副研究员的指导下，以浓度为核心变量，采用磷酸钒钠正极为研究对象，针对高盐浓度抑制电极溶解机制问题展开了系统研究。研究表明，在超高盐浓度Water-in-salt电解液中，电极材料溶解得到了很好的抑制，磷酸钒钠正极结构稳定性大大提高，电池电化学性能得到明显提升。31 m WIBS体系中在低倍率0.2C...
A voracious crab species is dramatically altering salt marsh ecosystems across the southeastern U.S., a new study reveals.Researchers at Brown University and other institutions found that so...
Salt marshes' capacity to store carbon may be threatened by nitrogen pollution（图）
Salt marshes capacity carbon nitrogen pollution
2019/10/18
Deep in the waterlogged peat of salt marshes, carbon is stored at much greater rates than in land ecosystems, serving as an offset to climate change caused by carbon dioxide (CO2) build-up in the atmo...

Winter Road Salt Fertilizers Turning North American Waterways Increasingly Saltier
2018/1/10
Across North America, streams and rivers are becoming saltier, thanks to road deicers, fertilizers and other salty compounds that humans indirectly release into waterways. At the same time, freshwater...

Salt substitution promising stroke management
2018/11/20
In this issue of the Journal, Pan et al. (1) report beneficial effects on recovery after stroke with 6 mo of the postacute use of a salt substitute. The trial switched regular salt (sodium chloride) f...
Intake of potassium- and magnesium-enriched salt improves functional outcome after stroke: a randomized, multicenter, double-blind controlled trial
stroke potassium magnesium enriched salt neurologic performance
2018/11/20
Background: Stroke is one of the leading causes of mortality and neurologic deficits. Management measures to improve neurologic outcomes are in great need. Our previous intervention trial in elderly s...
It has long been viewed that the analysis of sodium excretion in a morning “spot” urine sample is a valuable measure to estimate salt intake of the previous day. A study in this issue of the Journal s...
