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.

Low Nitrogen Fertilization Alter Rhizosphere Microorganism Community and Improve Sweetpotato Yield in a Nitrogen-Deficient Rocky Soil

Frontiers in Microbiology, 2020
Sweetpotato can be cultivated in the reclaimed rocky soil in Sichuan Basin, China, which benefits from the release of mineral nutrients in the rocky soil by microorganisms. Shortage of nitrogen (N) in the rocky soil limits sweetpotato yield, which can be

Characterization of volatile compounds profiles and identification of key volatile and odor-active compounds in 40 sweetpotato (Ipomoea Batatas L.) varieties

Food Chemistry: X
Sweetpotato with different flesh colors exhibits significant differences in flavor. Nevertheless, research on the identification of the key aromatic compounds in sweetpotato is scarce.

Hexaploid sweetpotato (Ipomoea batatas (L.) Lam.) may not be a true type to either auto- or allopolyploid.

PLoS ONE, 2020
To better define the sweetpotato polyploidy, we sought to reconstruct phylogenies of its subgenomes based on hybridization networks that could trace reticulate lineages of differentiated homoeolog triplets of multiple single-copy genes. In search of such

Diseases of Sweetpotato

, 2023
Sweetpotato is the sixth most important food crop globally. Whereas in developed countries like Canada, Europe, and the United States, it is considered a vegetable, it is a major staple food crop in sub-Saharan Africa. Cropping systems and varietal preferences vary between temperate and tropical countries.

High‐Quality Genome Assembly of Diplocarpon coronariae Unveils LTR Retrotransposon‐Driven Structural Dynamics in Fungi Evolution

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Long terminal repeat retrotransposons (LTR‐RTs) are recognised as a significant evolutionary force capable of shaping the structure and function of the genomes in eukaryotes, including animals, plants, and fungi. However, much remains largely unknown about how LTR‐RTs influence the evolution of fungi at the chromosomal level.

Genetic control of dry matter, starch and sugar content in sweetpotato

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
Sweetpotato (Ipomoea batatas L. (Lam)) is a nutritious food security crop for most tropical households, but its utilisation is very low in Ghana compared to the other root and tuber crops due to lack of end-user-preferred cultivars.

Assessment of the roles and farmer-preferred traits of sweetpotato in a crop-livestock farming system in Rwanda: implications for breeding dual-purpose varieties

Open Agriculture, 2020
In Rwanda, sweetpotato (Ipomoea batatas [L.] Lam) is a highly valued crop in a crop-livestock mixed farming system. The objective of this study was to assess the role of sweetpotato in the crop-livestock farming system, to identify farmer-preferred ...

Dynamics of Fusarium Infection in Melon (Cucumis melo): From Roots to Fruits

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Roots harboured the highest diversity of Fusarium species and served as the primary entry point for infection. Fusarium incidence increased as plants aged, with all parts showing fungal growth by 45 days after transplanting, indicating progressive colonisation throughout the growth cycle.
