Yam tuber (Dioscorea spp.) is a staple tropical crop that usually best eaten in its fresh form. However, inadequate preservation and storage can result yam tubers deterioration immediately after harvesting due to their relatively high moisture content. All the traditional structures of preserving storing could not maintain freshness for long time. Therefore, need developing new structure farm p...

Labour is one of the factors of production. And it is expected that with increase in adoption, the farmer’s output would increase and, consequently, there would be increases in the quantities of production inputs, and labour is one of such inputs. This study was, therefore, conducted to find out the effect of adoption on labour used for yam production by resource-poor farmers in Cross River Sta...

FIRST REPORT OF COLLETOTRICHUM ALATAE ON WATER YAM (DIOSCOREA ALATA) CAUSING LEAF ANTHRACNOSE IN PUERTO RICO

The annually reformulated trivalent inactivated influenza vaccine (TIV) includes both influenza A/subtypes (H3N2 and H1N1) but only one of two influenza B/lineages (Yamagata or Victoria). In a recent series of clinical trials to evaluate prime-boost response across influenza B/lineages, influenza-naïve infants and toddlers originally primed with two doses of 2008-09 B/Yamagata-containing TIV we...

Yams (Dioscorea spp) in Ghana are important food staples and the most non-traditional export crop contributing to foreign exchange incomes of smallholder producers. Research development over years produced release three improved Dioscorea rotundata varieties 2005. However, adoptions these have been very low. Using cross-sectional data from 544 randomly selected yam farmers employing logit model...

The complete genome sequence of Chinese yam necrotic mosaic virus (ChYNMV) consisting of 8,213 nucleotides containing one open reading frame was determined by the transcriptome data generated from Discorea opposita This is the first report of the complete nucleotide sequence of ChYNMV from Dioscorea opposita in the Republic of Korea.

Anomericformoftheproductsfremchitinase-catalyzedhydrolysis was analyzed by iH-NMR spectroscopy. When the chitinase from StreptenoTces griseus was added to the solution of substrate, Ai,AJ,IV,IV;IV-pentaacetylchitopentaitol, fi-anomer was first produced by the enzymatic hydrolysis, and then transformed to oc-anomer by mlltarotatioo. In contrast, the chitinase from Dioscorea qmpesita (yam) produc...
