Evo-devo of flowers and flowering genes: Salvia as a case study

Wetters, Sascha

Abstract (englisch):
The Plantae kingdom and its autotrophic representatives shape the surface of planet Earth and especially flowers contribute to a great amount to the astonishing beauty of nature. Naturally, flowers are not primarily intended to please humans, but they represent the sexual reproductive organs of the angiosperms, the flowering plants. The ingenious interaction of flowers with pollinators is an example for co-evolution and results in fine-scaled adaptations and complex floral shapes and structures. The unique staminal lever mechanism that is limited to the species rich genus Salvia from the Lamiaceae family is an extraordinary example for plant-pollinator interaction. The species of genus Salvia possess zygomorphic flowers, which have an amazing variety of petals and stamens, resulting in melitto- and ornithophily and worldwide distribution. In order to conduct a robust investigation on the evo-devo of Salvia flowers, the aim of the study was to take as holistic a view as possible on the genus Salvia by interweaving morphological, molecular and developmental approaches and put this against the background of speciation. Flowers of 24 Salvia species from different parts of the world were investigated with regard to their floral geometry. ... mehr
