Genetic diversity and population structure of pencil yam (Vigna lanceolata) (Phaseoleae, Fabaceae), a wild herbaceous legume endemic to Australia, revealed by microsatellite markers

Abstract: Pencil yam (Vigna lanceolata Benth.) (Phaseoleae, Fabaceae) is a herbaceous legume endemic to Australia. A previous morphological study suggested that pencil yam is a complex species of two or more related taxa with seven distinct morphological types (morphotypes) and, thus, taxonomic revision is necessary. In this study, we assessed genetic diversity and determined the genetic structure of a pencil yam collection of 62 accessions from seven morphotypes using 18 microsatellite (simple sequence repeat) markers … Show more

“…The previously proposed varieties angusta E. Pritz, filiformis Benth., lanceolata Benth. and latifolia C. T. White have been abandoned by all current classifications as insufficiently precise, leaving the issue of updating the genetic and phenotypic convolutedness of the species open (Nubankoh et al, 2015). The chromosome number of V. lanceolata is identical to that of its closest botanical relatives, x = 11 or 2n = 22 (Pasquet & Vanderborght, 1999).…”
