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 ...

Identification and functional characterization of IbSCPL18 regulating anthocyanin acylation and accumulation in sweetpotato

Scientia Horticulturae
Anthocyanin acylation is a crucial determinant of pigment stability and chemical diversity in purple-fleshed sweetpotato (Ipomoea batatas). However, the molecular mechanisms governing this modification remain largely elusive.

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.

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.

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

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.

Comparative physiological and transcriptome analysis between potassium-deficiency tolerant and sensitive sweetpotato genotypes in response to potassium-deficiency stress

BMC Genomics
Background Sweetpotato is a typical ‘‘potassium (K+) favoring’’ food crop, which root differentiation process needs a large supply of potassium fertilizer and determine the final root yield. To further understand the regulatory network of the response to

Impact of Organic and Inorganic Fertilizers on Yield and Interaction Effects in 10 Sweet Potato (Ipomoea batatas L.) Varieties Cultivated in the Southern USA

Advances in Agriculture, Volume 2026, Issue 1, 2026.
This study evaluated the effects of different fertilizer treatments on the growth performance and yield of multiple sweet potato (Ipomoea batatas L. Lam) varieties with diverse flesh colors, including orange, white, and purple. The primary objective was to investigate the interaction between fertilizer type and varietal response to identify optimal ...
