Genetic Diversity and Population Structure of Sweetpotato Accessions (Ipomoea batatas [L.] Lam.) Revealed by Single Nucleotide Polymorphism Markers

Plant Breeding, Volume 145, Issue 1, Page 85-94, February 2026.
ABSTRACT Use of molecular markers has improved the analysis of genetic variation by eliminating environmental influences on genotype performance. The objective of this study was to assess the genetic diversity (GD) and population structure of 327 sweetpotato genotypes sourced from the major sweetpotato‐growing regions of Zimbabwe and from the ...

A concise review of yam (Dioscorea spp.) starch: extraction, chemical composition, physicochemical properties and its potential food applications

Cogent Food & Agriculture
Substantial studies have been conducted on the starches derived from various yam species. These studies have examined numerous extraction methods, including acid, alkali, ammonia, water and enzymatic techniques, each yielding between 10–20% starch.

Discovery of a major QTL for resistance to Fusarium wilt (Fusarium oxysporum f. sp. batatas) in the hexaploid Covington sweetpotato

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Fusarium oxysporum f. sp. batatas, the causal agent of Fusarium wilt disease, was once the most damaging pathogen of sweetpotato in the United States. Breeding for cultivar resistance has largely addressed this issue, however, little is known about the genetic basis for resistance.

Characterization of the Omnivorous Lygus lineolaris Diet in a Strawberry Field by Metataxonomy

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This 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 ...

Functional synergy and genomic linkage of glyphosate resistance traits in Canada fleabane

Pest Management Science, Volume 82, Issue 1, Page 305-318, January 2026.
Stacking target‐site and non‐target‐site glyphosate resistance mechanisms in Conyza canadensis results in strong synergistic effects. This study quantifies gene × gene interactions and maps linked resistance loci, advancing our understanding of herbicide resistance genetics and informing management strategies.

Yams (Dioscorea spp.) in shellmounds and swiddens: ancient history in Babitonga Bay, Santa Catarina State, southern Brazil

Journal of Ethnobiology and Ethnomedicine
Background In Babitonga Bay, southern Brazil, records of yam consumption exist among shellmound builders from at least 4000 years ago. Shellmounds (sambaquis) are anthropogenic structures in the form of mounds with layers of shells associated with other ...

ACLIMATIZACIÓN DE PLÁNTULAS DE YAMPÍ (Dioscorea trifida) Y ÑAME (D. alata) PRODUCIDAS in vitro

Agronomía Costarricense, 2005
La siembra de yampí (Dioscorea trifida) y ñame (D. alata) en Costa Rica se realiza primordialmente con fines de exportación a Europa y Norteamérica. La producción nacional se ve seriamente limitada por la falta de semilla libre de plagas y enfermedades.
