当植物遭受逆境胁迫时, 转录因子(TFs)被诱导或抑制表达, 进入细胞核识别特定的顺式作用元件, 结合并调控自噬基因的表达, 从而调控细胞自噬活性。

When plants encounter adverse environmental conditions, the corresponding transcription factors (TFs) are induced or repressed to activate the gene expression of downstream ATG genes through binding the specific cis-elements in their promoters in the nucleus, thereby controlling the activity of cell autophagy.
