Neutral theory of molecular evolution

Developed by Motoo Kimura, who argued that most of the evolution of DNA sequences occurs by chance (genetic drift) rather than by natural selection.

Cytokinin binds to the CRE1 receptors to initiate a response that culminates in the elevation of transcription of the type- BARRs/ type- A ARRs.

Type-A ARRs negatively regulate cytokinin signaling by interacting with other proteins in a manner dependent on the phosphorylation state of the type-A ARR.

Type-B ARRs are activated by phosphorylation, which enables them to regulate the transcription of a set of target genes for cytokinin response, and type-A ARRs

F-box proteins called KISS ME DEADLY (KMD) proteins

negatively regulates the cytokinin response by targeting type-B ARR proteins for degradation via the E3 ubiquitin ligase complex, SCF-KMD
