The demand for ascorbate recycling capacity rises as the ascorbate pool size increases in Arabidopsis plants.

Ascorbate recycling is required for high ascorbate accumulation. Hence, when the ascorbate pool size is small, does the demand for ascorbate recycling decrease? We herein investigated the impact of ascorbate recycling capacity on ascorbate pool size in an ascorbate-deficient background. Our findings demonstrate that a lower ascorbate pool size lowers the need for ascorbate recycling capacity even under light stress.
