Abstract:

Belonging to bHLH(Basic Helix-Loop-Helix)transcriptional factor family,phytochrome- interaction factors(PIFs) are involved in many biological processes of plants. As the“hub”of intracellular signal regulation,PIFs not only participate in the regulation of plant growth and development,but also plays an important role in the process of plant resistance to stress. The main points of this paper are:PIFs integrate complex networks to regulate plant responses to abiotic stresses such as temperature,shading stress and drought,meanwhile,they mediate the defense of plants against biotic stresses such as pests and diseases through plant hormone signaling pathway. Our research could provide reference for further study of PIFs.

Key words: PIF, signal transduction, abiotic stress, biotic stress
