Dissection for Floral Micromorphology and Plastid Genome of Valuable Medicinal Borages Arnebia and Lithospermum (Boraginaceae).

ABSTRACT: The genera Arnebia and Lithospermum (Lithospermeae-Boraginaceae) comprise 25-30 and 50-60 species, respectively. Some of them are economically valuable, as their roots frequently contain a purple-red dye used in the cosmetic industry. Furthermore, dried roots of Arnebia euchroma, A. guttata, and Lithospermum erythrorhizon, which have been designated Lithospermi Radix, are used as traditional Korean herbal medicine. This study is the first report on the floral micromorphology and complete chloroplast (cp) genome sequences of A. guttata (including A. tibetana), A. euchroma, and L. erythrorhizon. We reveal great diversity in floral epidermal cell patterns, gynoecium, and structure of trichomes. The cp genomes were 149,361-150,465
