Phylogenetic tree of CCCH proteins in B. rapa. This tree includes 103 CCCH proteins from Brassica rapa and 68 from Arabidopsis thaliana. 84 of CCCH proteins in B. rapa can be grouped into 18 subfamilies and subfamily I-XI are based on reference [23], and subfamily XI-XVIII are new set. Solid circle shows the Arabidopsis CCCH proteins in subfamily I-XI. Protein sequences were aligned using MUSCLE, and the phylogenetic tree analysis was performed using MEGA 7.0. The tree was constructed with the following settings: Statistical Method as Maximum Likelihood; Include Gaps/Missing Data Treatment: Partial deletion; Substitution Model: Poisson model; and Bootstrap test of 1000 replicates for internal branch reliability
