Chromoanagenesis is a single catastrophic event that involves, in most cases, localized
chromosomal shattering and reorganization, resulting in a dramatically restructured …

Plants are the source of our understanding of several fundamental biological principles. It is
well known that Gregor Mendel discovered the laws of Genetics in peas and that maize was …

The shuffling of genetic material facilitated by meiotic crossovers is a critical driver of genetic
variation. Therefore, the number and positions of crossover events must be carefully …

Chromosome axis-associated HORMA domain proteins (HORMADs), eg ASY1 in
Arabidopsis, are crucial for meiotic recombination. ASY1, as other HORMADs, is assembled …

Modern plant breeding, such as genomic selection and gene editing, is based on the
knowledge of the genetic architecture of desired traits. Quantitative trait loci (QTL) analysis …

Abstract MutL homolog 1 (MLH1), a member of the MutL homolog family, is required for
normal recombination in most organisms. However, its role in soybean (Glycine max) …

Crossovers create genetic diversity and are required for equal chromosome segregation
during meiosis. Crossover number and distribution are highly regulated by different …

Mutations affecting crossover (CO) frequency and distribution lead to the presence of
univalents during meiosis, giving rise to aneuploid gametes and sterility. These mutations …

We show here that in the fungus Sordaria macrospora, the meiosis-specific HORMA-domain
protein Hop1 is not essential for the basic early events of chromosome axis development …

During meiosis, the chromosome axes and synaptonemal complex mediate chromosome
pairing and homologous recombination to maintain genomic stability and accurate …
