A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Comparative gene mapping in Arabidopsis lyrata chromosomes 6 and 7 and A thaliana chromosome IV: evolutionary history, rearrangements and local recombination rates [PDF]

, 2006
We have increased the density of genetic markers on the Arabidopsis lyrata chromosomes AL6 and AL7 corresponding to the A. thaliana chromosome IV, in order to determine chromosome rearrangements between these two species, and to compare recombination ...

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Hidden Strategies Beneath a Single Nucleotide: Contrasting Physiology in Lichen Photobiont Strains

Plant, Cell &Environment, EarlyView.
ABSTRACT Lichen photobionts exhibit significant physiological variability with important ecological implications. While this variability is relatively well studied at the interspecific level, it has rarely been examined at the intraspecific level. Here, we investigated the physiological responses to temperature and irradiance of two Trebouxia lynniae ...

Irr1/Scc3 Cohesin Interacts with Rec8 in Meiotic Prophase of Saccharomyces cerevisiae [PDF]

, 2011
The meiotic cohesin complex of S. cerevisiae shares with the mitotic one the Irr1/Scc3, Smc1, and Smc3 subunits, while the meiosis-specific subunit Rec8 re-places mitotic subunit Scc1/Mcd1.

The effects of recombination rate on the distribution and abundance of transposable elements [PDF]

, 2008
Transposable elements (TEs) often accumulate in regions of the genome with suppressed recombination. But it is unclear whether this pattern reflects a reduction in the efficacy of selection against deleterious insertions or a relaxation of ectopic ...

Meiotic recombination modulates the structure and dynamics of the synaptonemal complex during C. elegans meiosis.

PLoS Genetics, 2017
During meiotic prophase, a structure called the synaptonemal complex (SC) assembles at the interface between aligned pairs of homologous chromosomes, and crossover recombination events occur between their DNA molecules.

Genome‐wide association analysis of resistance to scald in an adapted multiparent winter malting barley population

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract Scald, caused by the fungus Rhynchosporium graminicola Heinsen 1897, is a major foliar disease in winter malting barley (Hordeum vulgare L). Resistance to scald in winter malting barley is controlled by major and minor resistance genes. We used a population of 377 lines derived from biparental crosses among five winter malting barley parents ...

Recombination dynamics of a human Y-chromosomal palindrome:rapid GC-biased gene conversion, multi-kilobase conversion tracts, and rare inversions [PDF]

, 2013
The male-specific region of the human Y chromosome (MSY) includes eight large inverted repeats (palindromes) in which arm-to-arm similarity exceeds 99.9%, due to gene conversion activity.
