This study identifies AtPUP5 as a plasma membrane transporter involved in riboflavin distribution in Arabidopsis reproductive organs, showing organ-specific overaccumulation in its absence.

This study shows that simultaneous knockout of VTC2 and VTC3 in plants reduces ascorbate levels and increases light stress sensitivity compared to single mutants.

The paper identifies and characterizes MIPs in six Phytophthora species, revealing distinct sequence and structural properties compared to other taxa.
