Abstract Background A wide range of stimuli evoke rapid and transient increases in Ca2 cyt in plant cells which are transmitted by protein sensors that contain EF-hand motifs. Here a group of Oryza sativa L. genes encoding calmodulin CaM and CaM-like CML proteins that do not possess functional domains other than the Ca2 -binding EF-hand motifs was analyzed. Results By functional analyses and BLAST searches of the TIGR rice database a maximum number of 243 proteins that possibly have EF-hand motifs were identified in the rice genome. Using a neighbor-joining tree based on amino acid sequence similarity five loci were defined as Cam genes and thirty two additional CML genes were identified. Extensive analyses of the gene structures the chromosome locations the EF-hand motif organization expression characteristics including analysis by RT-PCR and a comparative analysis of Cam and CML genes in rice and Arabidopsis are presented. Conclusion Although many proteins have unknown functions the complexity of .
