Multilocus sequence analysis of xanthomonads causing bacterial spot of tomato and pepper plants reveals strains generated by recombination among species and recent global spread of Xanthomonas gardneri [PDF]

, 2015
Four Xanthomonas species are known to cause bacterial spot of tomato and pepper, but the global distribution and genetic diversity of these species are not well understood.

Targeted recombination of homologous chromosomes using CRISPR‐Cas9

FEBS Open Bio, 2023
CRISPR mutagenesis is an efficient way to disrupt specific target genes in many model organisms. We previously devised a targeted CRISPR recombination method to generate intragenic recombinants of alleles in Drosophila.

Mapping of meiotic recombination in human preimplantation blastocysts

G3: Genes, Genomes, Genetics, 2023
Recombination is essential for physical attachments and genetic diversity. The Han Chinese population is the largest ethnic group worldwide, therefore, the construction of a genetic map regarding recombination for the population is essential.

Genetic Recombination in Micromonospora [PDF]

Journal of Bacteriology, 1971
Biochemical mutants were obtained from Micromonospora chalcea, M. purpurea , and M. echinospora by using ultraviolet radiation or nitrosoguanidine. Crosses carried out between complementary nutritional mutants of the same species showed positive genetic interaction.

Allopolyploidization increases genetic recombination in the ancestral diploid D genome during wheat evolution

Crop Journal, 2022
Genetic recombination produces new allelic combinations, thereby introducing variation for domestication. Allopolyploidization has increased the evolutionary potential of hexaploid common wheat by conferring the advantages of heterosis and gene ...

The Landscape of Realized Homologous Recombination in Pathogenic Bacteria [PDF]

, 2015
Recombination enhances the adaptive potential of organisms by allowing genetic variants to be tested on multiple genomic backgrounds. Its distribution in the genome can provide insight into the evolutionary forces that underlie traits, such as the ...

sequenceLDhot: Detecting Recombination Hotspots. [PDF]

, 2006
Motivation: There is much local variation in recombination rates across the human genome—with the majority of recombination occuring in recombination hotspots—short regions of around ~2 kb in length that have much higher recombination rates than ...

Interactions between BRCA2 and RAD51 for promoting homologous recombination in Leishmania infantum. [PDF]

, 2012
In most organisms, the primary function of homologous recombination (HR) is to allow genome protection by the faithful repair of DNA double-strand breaks.

Organellar inheritance in the green lineage: insights from Ostreococcus tauri [PDF]

, 2013
Along the green lineage (Chlorophyta and Streptophyta), mitochondria and chloroplast are mainly uniparentally transmitted and their evolution is thus clonal. The mode of organellar inheritance in their ancestor is less certain.

Assessing by Modeling the Consequences of Increased Recombination in Recurrent Selection of Oryza sativa and Brassica rapa

G3: Genes, Genomes, Genetics, 2019
Meiotic recombination generates genetic diversity but in most species the number of crossovers per meiosis is limited. Previous modeling studies showed that increasing recombination can enhance response to selection.
