Arabidopsis SnRK1 negatively regulates phenylpropanoid metabolism via Kelch domain‐containing F‐box proteins

What is it about?

Sucrose Non-Fermenting Related Kinase 1 reprograms metabolic processes upon cellular carbon deprivation. We examine if and how SnRK1-mediated sugar signaling pathway controls phenylpropanoid metabolism. We find that SnRK1 negatively regulates phenylpropanoid biosynthesis via a group of Kelch domain-containing F-Box proteins that are responsible for the ubiquitination and degradation of phenylalanine ammonia lyase.
