Abstract:
The plant defense responses included plant immunity against herbivores and pathogens，and defense responses to proximity of competitors.The signal recognition of herbivores and pathogens，the signal pathways of defense response hormones including salicylic acid and jasmonic acid were introduced firstly in this paper.Then the regulation function of light in the plant defense responses to proximity of competitors and the photoreceptors phytochromes B，cryptochromes and UVR8 were summarized.It was also discussed that the relationship of the R∶FR light signal，photoreceptors and signal pathways of plant defense response hormones.It was pointed out that competition signals perceived by photoreceptors could inhibit the plant defense responses to herbivores and pathogens.The main reason was that a low R∶FR ration resulted in inhibitions of jasmonic acid and salicylic acid signal transduction pathways.It could also lead to an inactivation of phytochromes B.This changed the balance between DELLA and JASMONATE ZIM DOMAIN proteins and resulted in an inhibition of jasmonic acid signal transduction pathway in further.
