Abstract: Phytochrome is one of the most important photoreceptors sensing the changes of the surrounding environment,which not only plays an important role in regulation of plant growth and development,but also modulates plant stress responses against both biotic and abiotic stresses. Some researches indicated that mutation of the phytochromes decreases defense resistance against biotic stresses like pathogens,and herbivores infection as well as abiotic stresses including cold,heat,drought,salinity and so on. Plant responded to stress differentially with the changes in R/FR ratio,which was associated with salicylic acid(SA),jasmonic acid(JA)and abscisic acid(ABA)signaling transduction. This review summarized recent progress in the study of phytochromes and light quality in plant stress response and discussed the potential application of light environment and phytochrome regulation in horticulture industry.

Key words: phytochrome, defense resistance, photoreceptors, biotic stress, abiotic stress, light quality
