Describe The Role of Blue Light in Transpiration by mondalsudip2710 is a document available to read on EtoBox.
Blue light is a crucial trigger for stomatal opening in plants, operating through a specific signal transduction pathway that involves photoreceptors like phototropins and zeaxanthin. The mechanism includes autophosphorylation, activation of proton pumps, ion influx, and osmotic swelling, leading to transpiration. Unlike red light, the blue light response is independent of photosynthesis and occurs even at low light levels, allowing plants to optimize CO2 capture for photosynthesis.
