Fig. 5: Genome-wide analysis of tandem gene duplication in the C. sinensis genome.

a C. sinensis genome topography and synteny. I represents the duplicated gene blocks within C. sinensis that were produced by ECH (green) and CRT (orange) events. II represents the frequency distribution of tandem genes in 1-Mb intervals across the 15 chromosomes, MAX = 22. III represents gene density ranging from 0 to 37 genes per Mb. b Identification of tandemly duplicated NBS-encoding genes. c Comparison of gene expression in eight tissues between tandem and nontandem NBS-encoding genes. d Comparison of the highly expressed apical genes between tandem and nontandem genes among the enriched genes involved in phenylpropanoid biosynthesis and flavonoid biosynthesis. e Phylogenetic tree and gene expression in eight tissues of six F3ʹ5ʹH genes belonging to two clusters
