Somatic genome‐doubling is the most parsimonious route to allopolyploidy

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2845-2851, June 2026.
Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.

Domestication history of a hexaploid, the sweet potato (Ipomoea batatas (L.) Lam.) [PDF]

open access: yes, 2009
Despite the importance of sweet potato as a food crop, its evolutionary history has been poorly investigated. The geographical and botanical origins of sweet potato remain unclear.

Variation of DNA methylation and phenotypic traits following unilateral sexual polyploidization in Medicago [PDF]

open access: yes, 2012
Sexual hybridization is an important generator of biodiversity and a powerful breeding tool. Hybridization can also overcome ploidy barriers when it involves 2n gametes, as in the case of unilateral sexual polyploidization (USP) that has been utilized in

Wheat breeding approaches for designing wheat to thrive in a warmer world

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 754-763, May 2026.
Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1399-1420, May 2026.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Gene Expression Changes During the Allo-/Deallopolyploidization Process of Brassica napus

open access: yesFrontiers in Genetics, 2019
Gene expression changes due to allopolyploidization have been extensively studied in plants over the past few decades. Nearly all these studies focused on comparing the changes before and after genome merger.

Detailed analyses of 12 hom(oe)ologous chromosome segments in the highly polyploid sugarcane genome [PDF]

open access: yes, 2012
Modern sugarcane cultivars (Saccharum spp.) are recognized as the crop with the most complex genome studied to date, mainly due to the very high level of vertical redundancy (2n = ca 12x = ca 120), together with an interspecific origin.

Consolidated bioprocessing of starchy substrates into ethanol by industrial Saccharomyces cerevisiae strains secreting fungal amylases [PDF]

open access: yes, 2015
The development of a yeast strain that converts raw starch to ethanol in one step (called Consolidated Bioprocessing, CBP) could significantly reduce the commercial costs of starch-based bioethanol. An efficient amylolytic Saccharomyces cerevisiae strain

A natural variation within duplicated AsWRKY49‐D2 drives the subgenomic functional divergence of homeologs in salt response of allohexaploid oats

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1367-1383, May 2026.
Transcriptome analysis of oats under salt stress identified ten important salt‐responsive transcription factor families, which show extensive functional divergence among three oat subgenomes. Further integration with a genome‐wide association study under salt stress identified the AsWRKY49‐D2 gene, whose elite haplotype holds substantial potential for ...

Characterization and Stress Response of the JmjC Domain-Containing Histone Demethylase Gene Family in the Allotetraploid Cotton Species Gossypium hirsutum

open access: yesPlants, 2020
Histone modification is an important epigenetic modification that controls gene transcriptional regulation in eukaryotes. Histone methylation is accomplished by histone methyltransferase and can occur on two amino acid residues, arginine and lysine ...
