Summary The circadian system allows plants to coordinate metabolic and physiological functions with predictable environmental variables such as dusk dawn. This endogenous oscillator is comprised of biochemical transcriptional rhythms that are synchronized a plant's surroundings via signals, including light temperature. We have used chlorophyll fluorescence techniques describe PSII operating efficiency ( ) in the chloroplasts Arabidopsis thaliana . These oscillations appear be influenced by...
Abstract Plants are acutely sensitive of their light environment, adapting growth habit and prioritizing developmental decisions to maximize fecundity. In addition providing an energy source directional information, quality also contributes entrainment the circadian system, endogenous timing mechanism that integrates environmental signalling cues promote growth. Whereas plants' perception red blue portions spectrum well defined, green sensitivity remains enigmatic. this study, we show low...
Abstract In this study, we assessed 43 accessions of Sorghum from 16 countries across three continents. Our objective was to identify stomatal and photosynthetic traits that could be exploited in breeding programs increase photosynthesis without increasing water use under dynamic light environments. Under field conditions, crops often have limited availability are exposed rapidly fluctuating intensity, which influences both behaviour. results highlight a tight coupling between rate (A)...
Abstract Plants exploit developmental plasticity to adapt their growth and development prevailing environmental cues. This provides a selective competitive advantage in nature but is obstructive during large-scale, intensive agricultural practices since economically important traits (including vegetative flowering time) can widely vary depending on local conditions. prevents accurate prediction of harvesting times produces variable crop. We sought restrict by manipulating signalling systems...
Plants exploit phenotypic plasticity to adapt their growth and development prevailing environmental conditions. Interpretation of light temperature signals is aided by the circadian system, which provides a temporal context. Phenotypic selective competitive advantage in nature but obstructive during large-scale, intensive agricultural practices since economically important traits (including vegetative flowering time) can vary widely depending on local This prevents accurate prediction...
The circadian system induces rhythmic variation in a suite of biochemical and physiological processes that serve to optimise plant growth diel cycles. To be greatest utility, these behaviors are coordinated with regular environmental changes such as the rising setting sun. Photoreceptors, along metabolites produced during photosynthesis, act synchronise internal timing mechanism lighting cues. We have recently shown phototropins help maintain robust rhythms photosynthetic operating...
The circadian clock system acts as an endogenous timing reference that coordinates many metabolic and physiological processes in plants. Previous studies have shown the application of osmotic stress delays rhythms via 3'-phospho-adenosine 5'-phosphate (PAP), a retrograde signalling metabolite is produced response to redox within organelles. PAP accumulation leads inhibition exoribonucleases (XRNs), which are responsible for RNA degradation. Interestingly, we now able demonstrate...
