Abstract: Phytochrome is a red and far-red light receptor,which not only plays an important role in plant morphogenesis,but also is involved in the regulation of plant defense resistance signaling pathway. Here,we present the reaction and mechanism of phytochrome and its interacted transcription factors regulating plant resistance to biotic stress,such as pathogens and pest,by inducing plant hormone signaling pathways. And we also review the mechanisms of phytochrome regulating abiotic stress,such as the competition of neighboring plants,drought,low temperature and high temperature. In addition,we discuss and prospect the challenges and future directions in the research of phytochrome.

Key words: phytochrome, disease resistance, insect resistance, abiotic stress
