Detection and diversity of viruses infecting African yam (Dioscorea rotundata) in a collection and F1 progenies in Côte d'Ivoire shed light to plant-to-plant viral transmission. [PDF]
Plant Pathol, 2021 A survey of leaf symptoms and viral molecular indexation on African yam germplasm and two hybrid populations unveiled a high prevalence of yam viruses in Côte d'Ivoire and provided evidence for their plant‐to‐plant transmission. Abstract Yam (Dioscorea spp.) is a major staple food whose production is hampered by viral diseases.

Profiling Anthocyanins in Thai Purple Yams (Dioscorea alata L.). [PDF]
Int J Food Sci, 2020 Two accessions of Thai purple yam (Dioscorea alata) were investigated for their chemical constituents during tuber development when the vines were 3 to 8 months old. Yam tubers contained total phenolic compounds ranging between 100 and 385 mg gallic acid equivalent (GAE), flavonoids 60–160 mg catechin equivalent (CE), monomeric anthocyanin of 10–90 mg ...

Characterization of the Omnivorous <i>Lygus lineolaris</i> Diet in a Strawberry Field by Metataxonomy. [PDF]
Ecol EvolThis study employs metataxonomy to reveal the extensive omnivorous diet of Lygus lineolaris in a strawberry field, identifying 475 host taxa and confirming active ingestion across plant and prey sources. We introduce a novel coefficient of omnivory, demonstrating the species' strong herbivorous bias while highlighting its dietary flexibility and ...

Comparative Study of the Physicochemical, Functional, Thermal, and Rheological Properties of Pretreated Flours From Dioscorea alata and Dioscorea rotundata [PDF]
Food Sci NutrPretreatments help improve flour quality. The increase in solubility and dispersibility is greater in D. rotundata. D. alata flours are more resistant to shear than D. rotundata flours. All flours degrade after 200°C. D. alata flours are more elastic while D. rotundata flours are more viscous.

The effect of gender on end‐user preferences for yam quality descriptors
Food Science &Nutrition, Volume 10, Issue 11, Page 3890-3904, November 2022., 2022 Sweet taste and mouldability are key quality indicators liked by both females and males. Males prefer yams with longer digestion time while females like aroma of yam. Varieties that are not watery and do not brown are important characteristics during processing. Abstract Improving the effectiveness of breeding programs could be achieved by breeding for
