E3 Ubiquitin LigasePdSINA2D in Populus deltoides Positively Regulates ABA-Dependent StressTolerance through Ubiquitination of FREE1 in Poplar

Abstract Populus deltoides “Shalinyang” (PdS) displays reduced tolerance to abiotic stresses. SINA (seven in absentia) proteins, a subtype of E3 ubiquitin ligases, play crucial roles in regulating plant growth and responses to abiotic stresses. However, the characteristics and po...
