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
