6Expression and function analyses of Arabidopsis MKK genes. (a) Expression of Arabidopsis MAPKK genes. X-axis indicates representative tissues and developmental stages and Y-axis represents RPKM (reads per kilobase of mRNA length per million of mapped reads) value. Gene pairs resulted from recent duplications are shown in color. Duplicate genes in same color are paralogs from a recent duplication. (b) Expression of AtMKK10 in wild-type Columbia and ag-12, ap1-15, ap2-6, ap3-6, clv3-7, lfy-12 and ufo-1 mutants. The x-axis indicates different samples and y-axis indicates RPKM value. (c) A multiple sequence alignments of the key phosphorylation site of the MKK10 and other Arabidopsis Group A of MAPKK proteins. (d) Tiling array **data** of Arabidopsis MKK genes under drought, cold, high-salinity, heat, genotoxic, osmotic, oxidative and wounding and UV-B light treatment
