Comportamiento del ñame (Dioscorea spp.)

The Journal of Agriculture of the University of Puerto Rico, 1989
Se evaluaron 18 cultivares de cinco especies de ñame (Dioscorea spp.) por su rendimiento y resistencia a mosaico, candelilla y la mancha negra en el campo durante 2 años consecutivos en Mayagüez e Isabela, Puerto Rico. La cultivar Mina de la especie D. trifida mostró síntomas severos de mosaico por lo cual arrojó una baja producción. Se evaluaron cinco

Metabolite profiling of Dioscorea (yam) species reveals underutilised biodiversity and renewable sources for high-value compounds [PDF]

, 2016
Yams (Dioscorea spp.) are a multispecies crop with production in over 50 countries generating ~50 MT of edible tubers annually. The long-term storage potential of these tubers is vital for food security in developing countries.

Complete plastome sequences of 14 African yam species (Dioscorea spp.) [PDF]

Mitochondrial DNA Part B, 2019
Complete plastomes of 14 African yam species were reconstructed from whole genome sequencing. These plastomes sizes varied from 151,908 to 155,155 bp. We predicted 130 genes, including 18 duplicated genes located in the two inverted regions. Phylogenetic analysis obtained using the maximum likelihood procedure revealed that each species was distinct ...

Caryatin and 3’-O-methylcaryatin contents in edible yams (Dioscorea spp.) [PDF]

Journal of Food Composition and Analysis, 2021
Abstract The genus Dioscorea hosts a large number of yam species used medicinally and as a staple food by millions of people in tropical countries. All yams share a high antioxidant activity that correlates with their total phenolics contents. However, knowledge of edible species antioxidant phenolics remains incomplete. Bioassay-guided fractionation

Search for scutellonema bradys resistance in yams (dioscorea spp.)

Journal of Science and Technology (Ghana), 2008
A study to examine variability in susceptibility of yams to Scutellonema bradys and to identify possible sources of resistance in Ghanaian yam germplasm (Dioscorea spp.) for use in yam improvement programmes, particularly, in West Africa was undertaken. Pot and field screening methodologies were used. In general, S. bradys and dry rot of tuber symptoms

A Sequence-Independent Strategy for Amplification and Characterisation of Episomal Badnavirus Sequences Reveals Three Previously Uncharacterised Yam Badnaviruses

Viruses, 2016
Yam (Dioscorea spp.) plants are potentially hosts to a diverse range of badnavirus species (genus Badnavirus, family Caulimoviridae), but their detection is complicated by the existence of integrated badnavirus sequences in some yam genomes.

Agromorphologic, genetic and methylation profiling of Dioscorea and Musa species multiplied under three micropropagation systems.

PLoS ONE, 2019
Plant in vitro vegetative propagation using classical semi-solid culture medium is limited due to the low degree of automation, suboptimal nutrient availability and induced physiological stress which often reduce its efficiency.

Efficiency of RAPD, ISSR, AFLP and ISTR markers for the detection of polymorphisms and genetic relationships in camote de cerro (Dioscorea spp.)

Electronic Journal of Biotechnology, 2014
Background: At present, species known as camote de cerro (Dioscorea spp.) are found only in the wilderness in Mexico, but their populations are extremely depleted because they are indiscriminately collected, it is urgent to evaluate the conservation ...
