Functional genomics of protein kinases in plants

Functional genomics has revolutionised the way that scientists approach biological questions, allowing for the comprehensive characterisation of the function of related proteins encoded in a genome. The sequencing of the genome of the model system Arabidopsis thaliana has enabled the beginning of functional genomics and the study of protein kinase families in plants. The large family of genes encoding protein kinases is a primary target of functional genomics studies in plants due to their importance in diverse physiological processes. This paper describes the functional genomics tools used to study the families of protein kinases in Arabidopsis, as well as progress in uncovering the functions of these proteins.
