A protein kinase that plays a key role in the global control of plant carbon metabolism is SnRK1 (sucrose non-fermenting-1-related protein kinase 1), so-called because of its homology and functional similarity with sucrose non-fermenting 1 (SNF1) of yeast. This article reviews studies on the characterization of SnRK1 gene families, SnRK1 regulation and function, interacting proteins, and the effects of manipulating SnRK1 activity on carbon metabolism and development.
Key words: Carbon partitioning, metabolic signalling, protein kinase, SnRK1.
