Response and rebalance: Jasmonates make citrus peels brighter
The Plant Cell: In a NutshellYue et al. explore how jasmonates regulate carotenoid production in citrus.
By Pengtao Yue
Background: Beautiful, bright peel colors attract animals to help disperse seeds and are preferred by consumers. In agricultural production, citrus fruit often suffers from uneven coloration and poor development…
