Antagonism between phytohormone signalling underlies the variation in disease susceptibility of tomato plants under elevated CO2
Increasing CO2 concentrations ([CO2]) have the potential to disrupt plant-pathogen interactions in natural and agricultural ecosystems, but the research in this area has often produced conflicting results. Variations in phytohormone salicylic acid (SA) and jasmonic acid (JA) signalling could be associated with variations in the responses of pathogens to plants grown under elevated [CO2]. In thi...
متن کاملLight 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 کاملAnnexin-Mediated Calcium Signalling in Plants.
Calcium-permeable channels underpin elevations of free calcium that encode specific signals in stress adaptation, development and immunity. Identifying the genes encoding these channels remains a central goal of plant signalling research. Evidence now suggests that members of the plant annexin family function as unconventional calcium-permeable channels, with roles in development and stress sig...
متن کاملSugar sensing and signalling networks in plants.
Plant sugar signalling operates in a complex network with plant-specific hormone signalling pathways. Hexokinase was identified as an evolutionarily conserved glucose sensor that integrates light, hormone and nutrient signalling to control plant growth and development.
متن کاملGlutamate in plants: metabolism, regulation, and signalling.
Glutamate occupies a central position in amino acid metabolism in plants. The acidic amino acid is formed by the action of glutamate synthase, utilizing glutamine and 2-oxoglutarate. However, glutamate is also the substrate for the synthesis of glutamine from ammonia, catalysed by glutamine synthetase. The alpha-amino group of glutamate may be transferred to other amino acids by the action of a...
