Synthetic photorespiratory bypass more stably increases potato yield per plant by improving photosynthesis.

ABSTRACT: The bioengineering of photorespiration has emerged as a key target for improving photosynthesis and crop yield. In our previous study, two photorespiratory bypasses, GOC and GCGT, were successfully established in rice, and the transgenic plants exhibited increased photosynthesis and yield. However, reduced seed-setting rates were observed in both GOC and GCGT rice. To overcome this bottleneck, we introduced the GOC bypass into potato, as potato is vegetatively reproduced without the need for pollination, unlike rice. After the GOC bypass was successfully established in potato, transgenic plants were tested in field experiments at different locations in China with contrasting climates. Consequently, the yield per plant increased by 21.3%-69.2% for GOC potatoes under normal growth conditions
