(a) A comparison of the number of genes encoding putative EF-hand proteins (green) in different species and their percentage of the total number of genes (blue). At, Arabidopsis thaliana; Ce, Caenorhabditis elegans; Dm, Drosophila melanogaster; Sc, Saccharomyces cerevisiae, Hs, Homo sapiens. (b) The number of Arabidopsis proteins having 1, 2, 3, 4, 5 or 6 EF-hands.
