Several current findings have shown that enhancing the photosynthetic process through genetic engineering could provide a technique to boost crop yield. Photosynthesis is the primary predictor of crop output and crop efficacy in capturing light, and converting it into biomass during the growing season, which is the main indicator of yield attributes, whether its biomass or grain. Boosting crop photosynthetic performance by metabolic changes in a changing environment is another area where information is lacking. In the present chapter, we would discuss present and prospective ways for boosting photosynthetic efficiency under different climate conditions, as well as their implications on photosynthesis activity. Our objective is to analyze the existing projects being made to better photosynthesis effectiveness. This paper investigates the impact of modifying the Calvin-Benson (CB) cycle, photorespiration, and electron transport on biomass and seeds yield. It highlights some surprise findings where harmful impacts were seen. In the preceding part, we discussed future possibilities such as integrating polygenic modulation of photosynthetic carbon absorption to boost yield potential and features that address yield variability.
