中文摘要: |
转录因子是能够结合某基因上游特异核苷酸序列上的蛋白质,活化后从胞质转位至胞核,通过识别和结合基因启动子区的
顺式作用元件,启动和调控基因表达。真核生物在转录水平上的基因表达调控,影响和控制着细胞和生物个体的许多生物学过
程。本文综述了转录因子的结构、分类以及其在植物干旱胁迫中发挥的作用。 |
英文摘要: |
Transcription factors can combine with the specific nucleotide sequence upstream from target genes, activating or
repressing the gene expression level. The regulation of gene expression in transcription level controls many biological processes. In this
paper, the structure and classification of transcription factor were reviewed and the role of transcription factors in drought-tolerance of
plants was also discussed. |
