WebDec 12, 2024 · Ctb1 and CTB4a enhance cold adaptation of rice at the booting stage. Ctb1 encodes an F-box protein that interacts with a subunit of the E3 ubiquitin ligase, Skp (Koji et al. 2010), while CTB4a encodes a conserved leucine-rich repeat receptor-like kinase (Zhang et al. 2024). Although some progress has been made in mapping and cloning of QTLs for ... WebNov 18, 2024 · Currently, only three QTLs, Ctb1, CTB4a and qPSR10, have been cloned and functionally characterized [23–25]. Ctb1 is the first gene to be identified that is related to chilling tolerance at the booting stage of rice. The F-box protein encoded by Ctb1 interacts with the subunit SKP1 of the E3 ubiquitin ligase complex .
