Characterization and Expression Profiling Analysis of Calmodulin Genes in Response to Salt and Osmotic Stresses in Pear (Pyrus bretschneideri Rehd.) and in Comparison with Arabidopsis

Figure 4

Synteny analysis of CaM gene family in pear (P. bretschneideri) and A. thaliana. The five PbCaM genes were located on four of the 17 pear chromosomes. The duplicated CaM gene pairs in pear and Arabidopsis are illustrated on pear chromosomes (Chr1–17) and Arabidopsis chromosomes (At1–5). Paralogous relationships of PbCaM and AtCaM genes are indicated by red solid color lines. The orthologous relationship of CaM genes between pear and Arabidopsis is indicated by blue solid color lines.
