The complete chloroplast genome of Mexican marigold (Tagetes erecta L., Asteraceae)

Tagetes erecta is an important ornamental and medicinal plant indigenous to Mexico and Guatemala. The complete chloroplast genome of T. erecta was newly sequenced in this study. The total chloropalst genome size of T. erecta was 152,055?bp. In total, 123 genes were indetified, including 79 protein-coding genes, 8 rRNA genes, and 37 tRNA genes. Twelve genes are containing introns (ycf3 and clpP contained two introns). The overall GC content of this genome was 37.4%. A further phylogenomic analysis of Asteraceae, including 23 taxa, was conducted for the placement of genus Tagetes. The complete plastome of T. erecta will provide a valuable resource for further genetic conservation, evolution, and molecular breading studies in Asteraceae.
