[Transcriptional regulation of plant genes and its significance in biology].

A change of gene expression pattern, especially at a transcriptional level, is one of the most important motivities for plant variation. In this study, the modes of gene transcriptional regulation in plant were systematically described from genetics and epigenetics aspects, respectively, as well as their significances to plant divergence and evolution. Based on the current knowledge, the prospects, applications and problems in this area were analyzed.
