Dual localization of PDI5 couples endoplasmic reticulum proteostasis to meristem organization and meiotic fidelity in Arabidopsis.
Plant growth and reproduction require coordinated control of hormone-dependent tissue patterning and faithful meiotic chromosome segregation, yet whether upstream proteostasis contributes to both processes remains unclear. Here, we show that Arabidopsis PROTEIN DISULFIDE ISOMERASE 5 (PDI5) contributes to auxin-associat...
