Abstract

The elucidation and removal of photorespiratory metabolic constraints will be necessary to improve crop yield in the next agricultural revolution. Fu et al. studied metabolic fluxes in the photorespiratory pathway and report that serine is the major export, whereas dynamic alterations in glycine pools orchestrate CO assimilation during the induction and relaxation of photorespiration.

摘要

阐明和消除光呼吸代谢限制将是下一次农业革命中提高作物产量的必要条件。Fu 等人研究了光呼吸途径中的代谢通量，报告丝氨酸是主要的出口物质，而甘氨酸池的动态变化在光呼吸的诱导和松弛期间协调 CO 同化。
