Rice Kinase Database:

             Protein kinases catalyze the transfer of phosphate moiety from a phosphate donor to the substrate molecule, thus playing critical roles in cell signaling and metabolism. Although plant genomes contain more than 1000 genes that encode kinases, knowledge is limited about the precise roles for the vast majority of these kinases. To elucidate gene functions and evolution of the rice kinase superfamily, we previously developed the rice kinase database RKD that integrated omics-scale data within a phylogenetic context. Here, we present an updated version, RKD 2.0, which contains metadata derived from NCBI GEO expression datasets. RKD 2.0 is efficient in performing in-depth transcriptomic analyses of kinase-encoding genes in diverse rice tissues and in response to biotic and abiotic stresses and hormone treatments.
