A Decoy Library Uncovers U-Box E3 Ubiquitin Ligases That Regulate Flowering Time in .

Targeted degradation of proteins is mediated by E3 ubiquitin ligases and is important for the execution of many biological processes. Redundancy has prevented the genetic characterization of many E3 ubiquitin ligases in plants. Here, we performed a reverse genetic screen in using a library of dominant-negative U-box-type E3 ubiquitin ligases to identify their roles in flowering time and reproductive development.
