endosperm carotenoid accumulation in endosperm requires expression of isoform PSY1. Total carotenoid content correlates with endosperm transcript levels at day 20 after pollination for PSY1, but not for isoforms PSY2 or PSY3 Zea mays
-
leaf carotenogenesis requires phytochrome-dependent and phytochrome-independent photoregulation of isoform PSY2 plus non-photoregulated expression of isoform PSY1 Zea mays
-
leaf isoform PSY1 is required for carotenogenesis in the dark and for heat stress tolerance Zea mays
