Available evidence shows that sweetpotato originated from either Central or South American
lowlands with subsequent dispersal to North America, Europe, Africa, Asia and the pacific …

Background Phylogenies reconstructed with only one or a few independently inherited loci
may be unresolved or incongruent due to taxon and gene sampling, horizontal gene …

Heterozyosity is an important feature of many plant genomes, and is related to heterosis.
Sweet orange, a highly heterozygous species, is thought to have originated from an inter …

We analysed a representative collection of New World sweet potato landraces (329
accessions from Mexico to Peru) with both chloroplast and nuclear microsatellite markers …

Sweet potato, Ipomoea batatas (L.) Lam., is an important food and industrial material crop
throughout the world. It is also an alternative source of bio-energy as a raw material for fuel …

Genetic diversity is the raw material for germplasm enhancement. Landraces and wild
species relatives of potato, which contain a rich gene pool of valuable agronomic traits, can …

Abstract Sweetpotato (Ipomoea batatas (L.) Lam.) is a widely grown food crop especially in
developing countries. Increasing storage-root yield and dry-matter content has been the …

Ipomoea trifida belongs to the family Convolvulaceae and is closely related to sweetpotato.
In this study, we reported the microsatellites in I. trifida sequence database, and tested their …
