referenceCryptochromes, phytochromes, and the protein COP1 regulate light-controlled stomatal development in Arabidopsis plants.
claimIn Arabidopsis thaliana, cryptochromes and phytochromes jointly mediate the regulation of stomata by light signals, and stomatal development is inhibited when mutant plants are irradiated by light of the corresponding wavelengths, which affects water transpiration in the plant.
claimPlants utilize photoreceptors, such as phytochromes and phototropins, to sense changes in external light conditions and trigger signaling pathways that regulate growth and development.
claimPlant photoreceptors, including phytochromes, cryptophylls, and phototropins, sense different light wavelengths and convert them into biosignals to regulate plant growth and development, as described by Xu et al. (2021), Spaninks and Offringa (2023), and Jeong et al. (2024).
claimGavassi et al. (2017) identified phytochromes as key regulators of abiotic stress responses in tomato plants.
claimUnder biotic and abiotic stresses, plants detect stress signals and utilize light energy to mobilize materials such as Na+, K+, phytochromes, and salicylic acid to activate defense systems and maintain physiological activities.
claimPhytochromes in plants regulate growth and development from germination to flowering as an adaptation mechanism to harsh environments.
claimPlant growth and development processes are regulated by phytochromes and phytohormones.
claimTomato phytochrome negatively regulates plant pigment maintenance, growth, development, and osmoprotectant accumulation.
claimCarvalho et al. (2011) reviewed the role of phytochrome in plant stress tolerance.
claimPhytochrome regulates the accumulation of jasmonic acid and participates in the regulation of defense gene expression under far-red light, as reported in a 2019 study.
