Light perception and signalling in higher plants.
Plants monitor changes in the ambient light environment using sensory photoreceptor families: the phototropins and cryptochromes, which absorb UV-A or blue light; the phytochromes, which sense red/far-red light; and the UV-B photoreceptors, which have not yet been identified. Recent advances suggest that photoreceptor-induced signalling cascades regulate light-modulated gene expression. These r...
متن کاملBlue light activates a specific protein kinase in higher plants.
Blue light mediates the phosphorylation of a membrane protein in seedlings from several plant species. When crude microsomal membrane proteins from dark-grown pea (Pisum sativum L.), sunflower (Helianthus annuus L.), zucchini (Cucurbita pepo L.), Arabidopsis (Arabidopsis thaliana L.), or tomato (Lycopersicon esculentum L.) stem segments, or from maize (Zea mays L.), barley (Hordeum vulgare L.),...
متن کاملStomatal Blue Light Response Is Present in Early Vascular Plants.
Light is a major environmental factor required for stomatal opening. Blue light (BL) induces stomatal opening in higher plants as a signal under the photosynthetic active radiation. The stomatal BL response is not present in the fern species of Polypodiopsida. The acquisition of a stomatal BL response might provide competitive advantages in both the uptake of CO2 and prevention of water loss wi...
متن کاملPhototropin blue light receptors and light-induced movement responses in plants.
Two blue light receptors in Arabidopsis, termed phot1 and phot2, which contain flavin chromophores and have intrinsic protein kinase activity, participate in several physiological processes. Lin looks at the genetic evidence regarding how these photoreceptors mediate blue light-induced phototropism, chloroplast relocalization, and opening of the stomatal aperture.
متن کاملPeptidoglycan Perception in Plants
Higher eukaryotes have evolved mechanisms to detect and discriminate between a wide range of commensal and infectious microorganisms. The first inducible line of defence common between plant and animal systems is microbe-associated molecular pattern (MAMP)-triggered immunity (MTI) [1,2]. MTI is based on the recognition of certain structurally highly conserved and, for the microbe, indispensable...
