Abstract:Most angiosperms produce trichomes--epidermal hairs that have protective or more specialised roles.In almost all species trichomes are multicellular and, in the majority, secretory. Despite the importance of multicellular trichomes for plant protection and as a source of high-value products, little is known about the mechanisms that control their development. Here we use natural variation between Antirrhinum (snapdragon) species to examine how trichome distribution is regulated and has evolved. We show that a … Show more
