The existence of the chromodomain and genome proportion of the intact form of the Ty3/Gypsy- like elements. (a) Existence of chromodomains in the Ty3/Gypsy-like elements. RTs of the intact LTR retrotransposons were used in generating the phylogenetic tree. The red and blue dots indicate the pepper and tomato Ty3/Gypsy- like elements, respectively. The filled and empty dots indicate the existence and absence of the chromodomains, respectively. Classified types of each subgroup are depicted by green letters. The bootstrap values were produced by a replication of 1000. (b) Genome proportions of the pepper intact Ty3/Gypsy-like elements. The individual intact Ty3/Gypsy-like elements are marked by the letters 'a' to 'z' in the phylogenetic tree and graph.
