Fig. 2From: Genome-wide identification of CNGC genes in Chinese jujube (Ziziphus jujuba Mill.) and ZjCNGC2 mediated signalling cascades in response to cold stressThe phylogenetic tree and line charts for a lineage of gene groups for ZjCNGC15. a The tree contains a gene of interest and 20 genes with the highest HI values. The horizontal axis represents HI. b Red, blue, and green lines represent the numbers of genes (sequences), species, and families contained in individual gene groups, respectively. The horizontal axis represents HIBack to article page
