Analysis of the recombination landscape of hexaploid bread wheat reveals genes controlling recombination and gene conversion frequency [PDF]

, 2019
Background: Sequence exchange between homologous chromosomes through crossing over and gene conversion is highly conserved among eukaryotes, contributing to genome stability and genetic diversity. A lack of recombination limits breeding efforts in crops;

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, Volume 13, Issue 27, 13 May 2026.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Nucleotide diversity maps reveal variation in diversity among wheat genomes and chromosomes

BMC Genomics, 2010
Background A genome-wide assessment of nucleotide diversity in a polyploid species must minimize the inclusion of homoeologous sequences into diversity estimates and reliably allocate individual haplotypes into their respective genomes.

Postglacial colonization and parallel evolution of metal tolerance in the polyploid Cerastium alpinum [PDF]

, 2005
The Fennoscandian flora is characterized by a high frequency of polyploids, probably because they were more successful than diploid plants in colonizing after the last Ice Age.

The subtelomeric region is important for chromosome recognition and pairing during meiosis [PDF]

, 2016
The process of meiosis results in the formation of haploid daughter cells, each of which inherit a half of the diploid parental cells' genetic material.

Introgression of a Terminal Segment From Chromosome 3S of Festuca mairei Increases Drought Resistance of Lolium perenne

Food and Energy Security, Volume 15, Issue 3, May/June 2026.
ABSTRACT Due to climate change, the requirement for increased resilience by grassland systems to onsets of ever‐increasing drought stresses makes the development of drought‐resistant forage crops a priority for future food and energy security. Novel ×Festulolium (Festuca × Lolium) cultivars offer unique opportunities to combine complementary traits ...

Chromosomal locations of genes that control wheat endosperm proteins [PDF]

, 1982
The nutritional valué and the unique dough-forming and baking properties of wheat flour largely depend on its protein contení and composition. Wheat endosperm has poor nutritional quality because it is deficient in certain essential amino acids ...

Intron Size and Genome Size in Plants [PDF]

, 2002
It has long been known that genomes vary over a remarkable range of sizes in both plants (Bennett, Cox, and Leitch 1997) and animals (Gregory 2001). It also has become evident that across the broad phylogenetic sweep, genome size may be correlated with ...

Esterification enhances carotenoid retention during bread‐making

Journal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4312-4319, May 2026.
Abstract BACKGROUND Carotenoids are plant‐derived antioxidants that contribute to human health and represent key quality traits in wheat‐based foods. However, they are highly unstable and prone to degradation during processing. Xanthophyll esterification has been identified as a natural mechanism that enhances carotenoid stability during grain storage.
