Fig. 1From: Genome-wide identification, evolutionary and expression analysis of the cyclin-dependent kinase gene family in peanutPhylogenetic tree of CDKs and CDKLs from Arachis hypogaea, Arachis duranensis, Arachis ipaensis and Arabidopsis thaliana. The phylogenetic tree was constructed using MEGA 7.0 by the Maximum-Likelihood method with 1000 bootstrap replications. The tree was classified into 8 different subfamilies (CDKA, CDKB, CDKC, CDKD, CDKE, CDKF, CDKG and CDK-like or CDKL) indicated by different color lines. Names in bold represent CDKs and CDKLs of Arachis hypogaea, and the grey colored names show CDKs and CDKLs of Arabidopsis. Upright blue triangles represent CDKs and CDKLs of Arachis ipaensis, whereas the inverted green triangles highlight CDKs and CDKLs of Arachis duranensisBack to article page
