Genotype, mulching, and cropping system interactions drive vegetative growth and storage root yield in temperate‐grown sweetpotato

Crop Science, Volume 66, Issue 3, May/June 2026.
Abstract Understanding interactions among genotype, environment, and management is crucial for optimizing crop performance under climate variability. Sweetpotato (Ipomoea batatas (L.) Lam.), a nutrient‐rich root crop increasingly cultivated in temperate regions, exhibits complex source‐sink dynamics that remain insufficiently characterized in organic ...

Genome‐Wide Identification and Expression Analysis of Pathogenesis‐Related Protein 1 in Sweet Potato and Its Two Relatives

Food Science &Nutrition, Volume 14, Issue 3, March 2026.
Pathogenesis‐related Protein 1 (PR1) is a core component of plant innate immunity. We identified 33, 50, and 36 PR1 genes in Ipomoea batatas, Ipomoea trifida, and Ipomoea triloba. Phylogenetic analysis clustered them into 5 groups. Two diploid wild species show high flower/flower‐buds expression, and most sweet potato PR1s are downregulated under ...

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

Coevolution and Functional Effects of Endosymbiotic Rickettsia in Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) Across China

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Two distinct lineages of L. invasa and the dominant endosymbiont, Rickettsia, was identified, followed by an analysis of its infection density across various developmental stages and tissues of L. invasa. Furthermore, two distinct strains of the Rickettsia endosymbiont were detected, and the phylogenetic relationships between these strains and their L.

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.

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 ...

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.

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 ...
