Photosynthesis is a highly integrated and regulated process which sensitive to any change in environmental conditions, because it needs balance the light energy absorbed by photosystems with consumed metabolic sinks of plant. Low temperatures exacerbate an imbalance between source sink, thus requiring adjustments photosynthesis maintain flow. itself functions as sensor this through redox state photosynthetic electron‐transport components regulates photophysical, photochemical processes chloroplast. Recent progress has been made understanding how plants sense low temperature signal. It clear that interacts other during cold acclimation involving crosstalk redox, sugar‐signalling pathways regulate plant temperatures.
