Is triose phosphate utilization important for understanding photosynthesis

Abstract

Photosynthesis in plants occurs in the chloroplast, which is considered an endosymbiotic organelle living within a host. Metabolism in the endosymbiont and host must be aligned and plants can only grow as fast as chloroplasts can provide resources. However, it is also true that photosynthesis can only be as fast as the plant can use resources from the chloroplast. The interaction between the chloroplast and the rest of the plant has fascinated researchers for many years Fabre et al. (2019) have exciting new data about source sink effects on photosynthesis, which is best predicted by the triose phosphate utlization limitation of photosynthesis but Kumarathunge et al. (2019) suggest that this behavior can be ignored.
