Última Morphological and genetic perspectives of hybridization in two contact zones of closely related species of Petunia (Solanaceae) in southern Brazil Acta Botanica Teixeira,Marcelo C.; Turchetto,Caroline; Hartke,Sara; Schnitzler,Carolina K.; Freitas,Loreta B.. ABSTRACT Interspecific hybridization has several consequences for parental species, from blurring species limits to the emergence of new taxa. Petunia axillaris and P. exserta occur in sympatry in southernmost Brazil and naturally hybridize despite their different pollination syndromes and habitat requirements. We employed genetic and morphological analyses to characterize two contact zones between the species with the aim of determining the effect of interspecific hybridization. Microsatellite loci and a morphometric evaluation of the corolla shape were used to classify individuals based on their origin as pure parental or hybrids. Corolla color was used to classify individuals a priori (white, red or intermediate, for P. axillaris, P. exserta or hybrid,...

ABSTRACT Studying the role of hybridization in the speciation of plants is one of the most thrilling areas of evolutionary biology. Hybridization in natural populations can act in opposition to divergence, contribute to adaptation through introgression or foster the emergence of new lineages via hybrid speciation. Species of the plant genus Petunia grow in open areas in southern South America. Some natural interspecific hybrid events have been described for the genus, such as between the endemic P. exserta and the widespread P. axillaris. Both species occur in sympatry in Serra do Sudeste (Brazil), where they occur in diverse habitats and exhibit floral divergence, which has been related to the attraction of different primary pollinators. The present study... Tipo: Info:eu-repo/semantics/article Palavras-chave: Gene exchange; Hybridization; Inbreeding; Introgression; Microsatellite; Petunia; Species limits.
