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...
Physiological mechanisms underlying OsNAC5-dependent tolerance of rice plants to abiotic stress
Abiotic stress Abscisic acid Arabidopsis Oryza OsNAC5 Seed germination
2015/2/5
To understand the functions of transcription factor OsNAC5 in response to abiotic stress, we generated transgenic rice plants with knockdown OsNAC5 by RNAinterfered (RNAi) and overexpressing OsNAC5, a...

GERMINATION PERFORMANCE OF SEQUENTIALLY HARVESTED TOMATO (Lycopersicon esculentum Mill.) SEED LOTS DURING SEED DEVELOPMENT UNDER SALT AND OSMOTIC STRESS
seed lots germination salt and osmotic stress
2010/12/2
This work concluded that tomato seeds harvested 70 days after anthesis showed the maximum germination not only under water but also salt stress. Seeds harvested earlier or later were more sensitive to...
