Mysterious meiotic behavior of autopolyploid and allopolyploid maize

Comparative Cytogenetics, 2018
This study was aimed to investigate the stability of chromosomes during meiosis in autopolyploid and allopolyploid maize, as well as to determine an association of chromosomes between maize (Zea mays ssp. mays Linnaeus, 1753) and Z.

Genetic identification and characterization of novel loci for flag leaf morphology traits in Chinese endemic wheat

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Flag leaf morphology (FLM) is a critical determinant of wheat (Triticum aestivum L.) photosynthetic efficiency and grain yield. Chinese endemic wheat, a unique genetic reservoir formed by long‐term adaptation to diverse and heterogeneous environments in China, harbors abundant, untapped allelic variation for traits related to environmental ...

Production, characterization, and potential utility of a newly synthesized allohexaploid wheat Triticum kiharae

Crop Journal
Established allopolyploid species often contain specific gene(s) dedicated to suppressing the pairing of homoeologous chromosomes during meiosis. A longstanding question is whether such genes in allopolyploids with lower ploidy levels can retain full ...

Spontaneous natural formation of interspecific hybrids within the Festuca-Lolium complex

Biologia Plantarum, 2020
Interspecific and intergeneric hybridization within the Festuca-Lolium complex is frequently used in forage plant breeding. However, little is known about the natural occurrence and competitiveness of such hybrids.

Genetic architecture of angular leaf spot resistance in cultivated strawberry shaped by epistasis and genotype‐by‐environment interactions

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Angular leaf spot (ALS), caused by Xanthomonas fragariae, is a bacterial disease that limits strawberry (Fragaria × ananassa) productivity worldwide. Although major resistance loci have been identified in wild Fragaria species, their introgression into elite germplasm remains constrained by linkage drag and inconsistent inheritance. To dissect

Chromosome instability in intergeneric hybrids of Triticum aestivum;× tritordeum (amphiploid Hordeum chilense×Triticum turgidum) with high dosage of Ph1 gene of wheat [PDF]

, 1991
In somatic cells of intergencric hybrids Truicum uestirum (mono-isosomic 5BL, 2n=6x=4f)x trinordum 12n = 6x = 42, amphiploid Hordeum clulense x Triticum turgidnm)it was observed that high dosage of the long arm of 5B induced chromosome instability in ...

Homoeologous chromosome pairing between the A and B genomes of Musa spp. revealed by genomic in situ hybridization [PDF]

Annals of Botany, 2011
Most cooking banana and several desert bananas are interspecific triploid hybrids between Musa acuminata (A genome) and Musa balbisiana (B genome). In addition, M. balbisiana has agronomical characteristics such as resistance to biotic and abiotic stresses that could be useful to improve monospecific acuminata cultivars.

VERNALIZATION2 alters early tiller development in a facultative spring hexaploid bread wheat

New Phytologist, Volume 250, Issue 6, Page 4022-4035, June 2026.
Summary An extended period of cold exposure enables the process of vernalization in winter cereals and is important for the synchronised timing of the floral transition. The cereal‐specific floral repressor VERNALIZATION2 (VRN2) has an integral role in vernalization, yet this locus remains poorly characterised in facultative spring hexaploid wheat ...
