Phylogenetic status of Vavilovia formosa (Fabaceae-Fabeae) based on nrDNA ITS and cpDNA sequences

The phylogenetic status of the monotypic genus Vavilovia was studied using nrDNA ITS and cpDNA trnL-F and trnS-G regions. The results from the analysis of each dataset and the combined dataset, revealed that Vavilovia is closely related to Pisum, forming a group that is sister to Lathyrus. The molecular data and some morphological and biological characteristics strongly indicate that Vavilovia should be subsumed under Pisum, as Pisum formosum. (C) 2010 Elsevier Ltd. All rights reserved.
