Cross-species amplification of primers developed from Plantago major and P. intermedia in two Hawaiian Plantago species from the section Plantago

Thirty-nine primers, developed from the sister species Plantago major and P. intermedia, were tested in two Hawaiian Plantago species from the section Plantago. Eight primers were polymorphic, of which three were published earlier, and five are new ones presented here. Amplification and polymorphism levels appeared to be high in these Hawaiian species. These markers will be valuable for further mating system and evolutionary studies in species from the section Plantago that are closely related to P. major and P. intermedia.
