A Quick HYL1-Dependent Reactivation of MicroRNA Production Is Required for a Proper Developmental Response after Extended Periods of Light Deprivation

Achkar et al. show that a nuclear reserve pool of inactive phosphorylated HYL1, an essential cofactor for microRNA biogenesis, is resistant to dark- or shade-induced degradation. Upon light restoration, this HYL1 pool is quickly dephosphorylated to rapidly restore miRNA production and switch the developmental program to light-dependent growth.
