Abstract Photoreceptors are primarily known as key photomorphogenic modulators of various physiological events during plant development. Although there different groups photoreceptors, the phytochrome B (phyB) family mediates developmental responses in a wide range species, from seed germination to flowering. In addition, these molecules also regulate abiotic stress acclimation responses, such salinity, drought, low/high temperature, high light and heavy metals. The signalling pathways mediated by phyB could enhance resistance environmental stresses, photoreceptors reduce leaf transpiration, increase antioxidant system, protective pigments expression genes related acclimation. Thus, elucidation positive or negative roles for tolerance characteristics would provide essential knowledge genetic engineering, improving growth development critical environments. this review, we cover main findings on how works modulate discussing biochemical molecular aspects underlying mechanisms operated photoreceptors.
