Symbiotic relationships are everywhere in nature. In the soil, for example, mycorrhizal fungi enhance water and nutrient absorption for plants while feeding on sugars their roots release. In another c...
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...
Climate change ‘double whammy’ could kill off fish species Warming waters rob fish of ability to both move and adapt to cope
climate change warming oceans adaptation of fish
2021/8/10
New study of 150 million years of fish evolution provides first evidence to support scientific theory that commonly-eaten fish species will become smaller as waters warm under climate change. However,...
