Phylogenetic tree of the zf_CCCH protein sequence of soybean. The full-length protein sequences of 116, 50, 43, 49, 68 and 67 zf_CCCH proteins from soybean, Medicago truncatula, Phaseolus vulgaris, Vigna unguiculata, Arabidopsis thaliana and rice respectively, were aligned by MUSCLE and constructed the phylogenetic tree using the maximum-likelihood method in IQTREE with 1000 bootstrap replicates. The numbers beside the branches represent bootstrap values (≥500) based on 1000 replications that were used to class the major 17 subfamilies, subfamily I-XVII in the color circle is based on the reference [10]. The circles at the end of tree nodes marked with blue, red, orange, green, darkgreen and purple colors refer to Arabidopsis thaliana, rice, soybean, Medicago truncatula, Phaseolus vulgaris and Vigna unguiculata, respectively
