Developmental genes are believed to contribute to major changes during plant evolution, from infrageneric to higher levels. Due to their putative high sequence conservation, developmental genes are rarely used as molecular markers, and few studies including these sequences at low taxonomic levels exist. WUSCHEL-related homeobox genes (WOX) are transcription factors exclusively present in plants...

Lutzomyia spp. are New World phlebotomine sand flies, many of which are involved in the transmission of human diseases, such as leishmaniases and bartonellosis. The systematic classification of the approximately 400 species in the genus has been based on morphological characters, but the relationships within the genus are still very much in question. We have inferred phylogenies of 32 species o...

The snake gourd genus, Trichosanthes, is the largest genus in the Cucurbitaceae family, with over 90 species. Recent molecular phylogenetic data have indicated that the genus Gymnopetalum is to be merged with Trichosanthes to maintain monophyly. A revised infrageneric classification of Trichosanthes including Gymnopetalum is proposed with two subgenera, (I) subg. Scotanthus comb. nov. and (II) ...
