郭旺珍 经济作物 发育
2024/6/11
干旱是限制植物种植分布、生长发育以及作物产量的主要非生物胁迫因素之一。棉花是重要的经济作物，新疆是中国棉花种植的主要地区，占全国棉花种植面积80%以上。干旱胁迫是影响新疆棉花生产重要的非生物胁迫因素。挖掘关键抗旱基因，揭示棉花对干旱胁迫的应答机制，培育耐逆新材料和新品种，不仅具有重要的科学研究价值，也是服务棉花可持续发展的重要保障。NAC转录因子在植物非生物胁迫信号中起着重要的转录调控作用。然而，...
The collapse of the Hittite Empire in the Late Bronze Age has been blamed on various factors, from war with other territories to internal strife. Now, an interdisciplinary collaboration used tree ring...
Systematical characterization of YUCCA gene family in five cotton species, and potential functions of YUCCA22 gene in drought resistance of cotton
棉花 YUC基因家族 生长素合成
2024/5/17
生长素在植物的正常生长发育中起着至关重要的作用。TAA/YUCCA基因家族编码色氨酸氨基转移酶（tryptophan aminotransferase），是生长素合成的关键酶。然而，棉花中YUCCA（YUC）基因家族尚未见报道。为了揭示YUC基因在棉花中的功能，我们系统地鉴定了五个棉种中的YUC基因家族，包括成员分析、特征描述、基因组内复制和共线关系。转录组学分析表明，GhYUCs参与了棉花的非生...
The Millennium Drought (southeastern Australia) provided a natural experiment to challenge the assumption that watershed streamflow always recovers from drought.
