During 2007 survey of post-harvest diseases of yam performed in May and June, severe tuber loss caused by blue mold was observed in Iksan, Cheonbuk Province. Two species of Penicillium were isolated from the infected tubers. Based on β-tubulin gene sequence analysis, and cultural and morphological characteristics, the isolates were identified as Penicillium sclerotigenum and P. polonicum. P. sc...

• Bone mineral density (BMD) is used as an indicator of osteoporosis. BMD is measured and quantified by T-score, whose units are standard deviations relative to that of young, healthy adults (Young Adult Mean [YAM]). The International Osteoporosis Foundation (IOF) defines osteoporosis as a T-score of -2.5 or lower, i.e., worse. Severe osteoporosis is defined as a T-score of -2.5 or lower, and p...

Changes in sugar composition occur continuously plant tissues at different developmental stages. Tuber dormancy induction, stability, and breaking are very critical transitions yam crop production. Prolonged tuber after physiological maturity has constituted a great challenge genetic improvement productivity. In the present study, biochemical profiling of non-structural tubers during was perfor...

Yam (Dioscorea spp.) is a staple food crop and source of income for millions people in West Africa. Traditionally, Africa, yams are grown without any external inputs, leading to low tuber yields. The rapid decrease yield observed after the first yam cropping season has been ascribed nutrient depletion and/or accumulation yam-specific pests diseases. This led farmers grow on new surfaces under f...
