  • Title: [Auxin response factors and plant growth and development].
    Author: Liu ZH, Yu YC, Xiang FN.
    Journal: Yi Chuan; 2011 Dec; 33(12):1335-46. PubMed ID: 22207379.
    Abstract:
    An important aspect of studies on auxin is auxin response factors (ARFs), which activate or repress the auxin response genes by binding to auxin response elements (AuxREs) on their promoters. In this review, we focused on molecular biological advances of plant ARF families, and discussed ARF structures, regulation of ARF gene expression, the roles of ARFs in regulating the development of plants and in signal transduction and the mechanisms involved in the target gene regulation by ARFs. The phylogenetic relationships of ARFs in plants are close and most of them have 4 domains. ARFs are expressed in various tissues. Their expressions are regulated at both transcriptional and post-transcriptional levels. They play important roles in the interactions between auxin and other hormones.
