Phylogenetic relationships, gene structure and conserved motifs analysis in the ZjHsp70 and ZjHsp100 family protein in Z. jujuba. a The unrooted phylogenetic tree shows sub-families of ZjHsp70s (I–VII) and ZjHsp100s (I–III) are highlighted with different coloured backgrounds. b Gene structure analysis of ZjHsp70 and ZjHsp100 gene family members. The sizes of the exons and introns can be estimated using the scale given at the bottom. c Conserved motif analysis of the ZjHsp70 and ZjHsp100 family protein in Z. jujuba. Each coloured box represents a motif in each of the ZjHsp70 and ZjHsp100 proteins
