Although the CDPK gene family has been characterized in several model plants, little is known about this gene family in <i>Hevea brasiliensis</i> (the Para rubber tree). Here, we characterize the entire <i>H. brasiliensis</i> CDPK and CDPK-related kinase (CRK) gene families comprising 30 <i>CDPK</i> genes (<i>HbCPK1</i> to <i>30</i>) and nine <i>CRK</i> genes (<i>HbCRK1</i> to <i>9</i>). Structure and phylogeny analyses of these <i>CDPK</i> and <i>CRK</i> genes demonstrate evolutionary conservation in these gene families across <i>H. brasiliensis</i> and other plant species.
