Abstract
Protein synthesis is an essential but energetically expensive cellular process that is challenged under environmental stress in plants. Recent work demonstrates that the plant hormone ethylene, through GCN2, represses general translation during flooding stress to conserve energy. Moreover, ethylene also promotes the translation of specific stress-responsive mRNAs to survive submergence stress.
摘要
蛋白质合成是一种基本但耗能巨大的细胞过程，在植物面临环境压力时会受到挑战。最近的研究表明，植物激素乙烯通过 GCN2 在水淹胁迫下抑制一般翻译来节约能量。此外，乙烯还促进特定应激响应 mRNA 的翻译，以在淹没胁迫下存活。
