Genome‐wide development of intra‐ and inter‐specific transferable SSR markers and construction of a dynamic web resource for yam molecular breeding: Y2MD

open access: yesThe Plant Genome, Volume 17, Issue 2, June 2024.
Abstract Microsatellite markers are widely used in population genetics and breeding. Despite the economic significance of yams in developing countries, there is a paucity of microsatellite markers, and as of now, no comprehensive microsatellite marker database exists. In this study, we conducted genome‐wide microsatellite marker development across four

Isolation and kinetic properties of phosphorylase from Yellow Yam Tuber (Dioscorea cayenensis)

open access: yesBiologia plantarum, 1991
Two forms of α-glucan phosphorylase were isolated fromDioscorea cayenensis by ammonium sulphate gradient solubilization and further purified using starch adsorption and ion exchange chromatography on DEAE-Sephadex A-25 colunm. Fraction DC1was purified 80 fold with specific activity of 400 umol min−1 mg−1 protein, while fraction DC2showed 60 fold ...
