Fig. 1

Gene map of the complete chloroplast genome of cultivated tea. The inner circle corresponds to the GC content, and the next circle corresponds to the GC skew. The next three circles correspond to the genes. Genes with clockwise arrows represent reverse strands, while genes with counterclockwise arrows represent forward strands. Blue, red and aqua colors of the blocks represent protein-coding genes, introns and RNA, respectively. The third circle corresponds to the shared genes among three cultivated tea. The fourth circle corresponds to the unique genes of Camellia sinensis var. sinensis Anhua and Camellia sinensis var. sinensis Longjing43. The fifth circle corresponds to the unique genes of Camellia sinensis var. assamica cv. Yunkang10
