Heterogeneous Evolutionary History Defines the Rear Edge of the North American Herb Campanula americana

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim Warmer range limits of species distributions offer a window into the ecological and evolutionary processes associated with long‐term warming, as they often harbour relicts of refugial populations from the last glaciation. However, warm‐edge populations vary in their refugial, evolutionary, and climatic histories, complicating their use as ...

Characterization and Genetic Analysis of Traits in Autotetraploid Progeny of a Gossypium herbaceum L.

Agronomy
Polyploidization is a key pathway for species formation and genetic innovation; approximately 70% of angiosperms have undergone at least one whole-genome duplication event during their evolutionary history.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, Volume 250, Issue 1, Page 629-647, April 2026.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Potato dihaploids uncover diverse alleles to facilitate diploid potato breeding

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Commercial potato (Solanum tuberosum) in North America is a clonal autotetraploid crop, which complicates breeding. Efforts are underway to convert potato to a diploid inbred‐hybrid crop, allowing breeders to more quickly meet market and environmental demands.

Sox Gene Family Revealed Genetic Variations in Autotetraploid Carassius auratus

Frontiers in Genetics, 2020
The Sox gene family encoded transcription factors that played key roles in developmental processes in vertebrates. To further understand the evolutionary fate of the Sox gene family in teleosts, the Sox genes were comprehensively characterized in fish of

Genome‐wide association studies and genomics‐informed breeding for tuber dormancy in tetraploid potatoes

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Upon harvest, potato (Solanum tuberosum L.) tubers enter a dormant state and do not sprout even under favorable conditions. Early dormancy break causes tuber spoilage and reduces postharvest quality. Common sprout control methods may compromise tuber quality, raise health and environmental concerns, and increase costs.

Association of Grain Shedding Habit with Polyploidy in Tartary Buckwheat (Fagopyrum tataricum) Strains

Plant Production Science, 2004
Sixty tartary buckwheat (Fagopyrum tataricum) strains were investigated for grain shedding habit, plant height, grain yield, dry weight of plant, weight of grain, days to flowering after sowing and DNA content of nuclei.

Single Cell Multiomics of Hooked Potato Stolons Reveals Parallels to Shoot Apical Meristems in Arabidopsis

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1822-1838, March 2026.
ABSTRACT Solanum tuberosum L. (potato) is a key food crop, with its tubers serving as an important food source worldwide. Tuber development is a tightly regulated process involving the transition of a hooked stolon (a modified stem) to a tuber following the perception of mobile signals within the stolon tip. While genes like FLOWERING LOCUS T homologue

Estimating Effective Number of Breeders Under the Heterozygote‐Excess Equilibrium

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Estimating the effective number of breeders per reproductive cycle or cohort (Nb$$ {N}_b $$) can contribute to understanding the viability of wild populations. However, previous Nb$$ {N}_b $$ estimators based on heterozygote‐excess assume that parental genotypes are in accordance with Hardy–Weinberg equilibrium (HWE), and can only be applied ...

Comparative Morphological, Physiological, and Transcriptomic Analyses of Diploid and Tetraploid Wucai (Brassica campestris L.)

Plants
Polyploid plants often exhibit superior yield, stress resistance, and quality. In this study, homologous tetraploid wucai (Brassica campestris L.) was successfully obtained by spraying seedling growth points with colchicine.
