Solanaceae Source

A global taxonomic resource for the nightshade family

Next SolSeminar will be presented by Marco Anguiano Constante on Biogeography of Lycianthes in Mexico

Abstract. Exploring the biogeographic patterns in a megadiverse country like Mexico allow us to understand the evolutionary processes that have given rise to its diversity and endemism. Lycianthes is the third most diverse genus of Solanaceae with 152 species, 10 subspecies and 25 varieties distributed in America (North, Central, South America and the Caribbean) and the Asia-Pacific region (Southeast Asia and Oceania). Its greatest diversity is concentrated along the Andes in South America. However, Mexico is home of 44 species and four varieties, 20 species and two varieties are endemic. The high diversity and centers of endemism of Lycianthes in Mexico is in 14 and eight cells along the Mexican Transition Zone (MTZ), respectively. The evolutionary processes that allowed Mexico has high diversity and endemism was tested with Lycianthes series Meizonodonte. The series is a monophyletic group of 10 taxa and is associated with the MTZ. Lycianthes moziniana is endemic perennial herb, but widespread in Mexico that show genetic and morphological variation throughout its distribution. The geographic isolation of their populations favored their genetic structure and differentiation into three geographic groups. The diversity patterns of Lycianthes in Mexico are the result of the geological and climatic history of the MTZ.
