Hox genes reveal genomic DNA variation in tetraploid hybrids derived from Carassius auratus red var. (female) × Megalobrama amblycephala (male)

open access: yesBMC Genetics, 2017
Background Allotetraploid F1 hybrids (4nF1) (AABB, 4n = 148) were generated from the distant hybridization of Carassius auratus red var. (RCC) (AA, 2n = 100) (♀) × Megalobrama amblycephala (BSB) (BB, 2n = 48) (♂).

Relevance of unilateral and bilateral sexual polyploidization in relation to intergenomic recombination and introgression in Lilium species hybrids [PDF]

open access: yes
Sexual polyploids were induced in diploid (2n = 2x = 24) interspecific F1 hybrids of Longiflorum × Asiatic (LA) and Oriental × Asiatic (OA) Lilium hybrids by backcrossing to Asiatic (AA) parents as well as by sib-mating of the F1 LA hybrids.

Chromosome Stability of Synthetic-Natural Wheat Hybrids

open access: yesFrontiers in Plant Science, 2021
Primary allopolyploids are not only ideal materials to study species evolution, but also important bridges in incorporating genetic diversity of wild species into crops.

Loss of redundant gene expression after polyploidization in plants

open access: yes, 1978
Based on chromosomal location data of genes encoding 28 biochemical systems in allohexaploid wheat,Triticum aestivum L. (genomes AABBDD), it is concluded that the proportions of systems controlled by triplicate, duplicate, and single loci are 57%, 25 ...

Phylogenetic relationships in Betula (Betulaceae) based on AFLP markers [PDF]

open access: yes, 2008
The genus Betula comprises various species in boreal and temperate climate zones of the Northern Hemisphere. The taxonomy of Betula is controversial and complicated by parallel evolution of morphological traits, polyploidization events, and extensive ...

Polyploidization and epigenetics [PDF]

open access: yesChinese Science Bulletin, 2011
The occurrence of polyploidy, or whole genome duplication, can result in instantaneous speciation. Because new polyploids are immediately reproductively isolated from their non-polyploid congeners, polyploidization has played an important role in the diversification of flowering plants and some vertebrates.

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

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
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

Diagnostic yield of OCT3/4 reflex testing in testicular biopsy

open access: yesHistopathology, EarlyView.
GCNIS detection frequency was 48/3353 (1.4%) testicular biopsies from 42/1870 (2.2%) men who underwent testicular biopsy with or without testicular sperm extraction (TESE). OCT3/4 was particularly helpful for detecting interstitial seminoma, GCNIS coexisting with mature spermatogenesis, and focal GCNIS.

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, EarlyView.
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 ...

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, EarlyView.
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 ...
