Little Evidence for Homoeologous Gene Conversion and Homoeologous Exchange Events in Gossypium Allopolyploids

This paper analyzes homoeologous gene conversion and exchange in Gossypium allopolyploids using a new method and finds little evidence for gene conversion, with only one shared homoeologous exchange event identified.

Genome evolution and introgression in the New Zealand mud snails Potamopyrgus estuarinus and Potamopyrgus kaitunuparaoa

This paper sequences and analyzes the genomes of two New Zealand snail species, showing their genetic similarity, introgression between them, and their relationship to the invasive P. antipodarum.

Genome-wide patterns of homoeologous gene flow in allotetraploid coffee

This study uses a modified ABBA-BABA test to detect homoeologous gene flow in allotetraploid coffee, finding maternal bias in plastid-targeted genes and evidence of natural selection shaping gene flow direction.

Single-molecule sequencing of animal mitochondrial genomes reveals chloroplast-like architecture and repeat-mediated recombination

This study uses long-read sequencing to analyze mitochondrial genomes of two snail species, revealing chloroplast-like architecture and repeat-mediated recombination, suggesting non-maternal mitochondrial inheritance.

Organellar transcripts dominate the cellular mRNA pool across plants of varying ploidy levels

The paper analyzes mRNA transcript abundance in polyploid and diploid plants, finding that organellar genomes produce most transcripts despite having fewer genes.

Variation in cytonuclear expression accommodation among allopolyploid plants

This study examines cytonuclear expression accommodation in six allopolyploid plant lineages, finding variable maternal preferences and expression biases that do not consistently resolve nuclear-cytoplasmic incompatibilities.

Dual domestication, diversity, and differential introgression in Old World cotton diploids

This study investigates the domestication and genetic diversity of two diploid cotton species, confirming independent domestication and identifying patterns of introgression and chromosomal variability.

Global patterns of subgenome evolution in organelle-targeted genes of sixallotetraploid angiosperms

The paper examines subgenome evolution in organelle-targeted genes of six allotetraploid angiosperms and finds no global effects of cytonuclear incompatibilities on paternal homoeologs.

Nuclear-cytoplasmic balance: whole genome duplications induce elevated organellar genome copy number

This study investigates how whole genome duplications affect nuclear and organellar genome copy numbers in plants, finding that polyploids maintain cytonuclear stoichiometry through elevated organellar genome copy numbers.

Phenotypic variation in mitochondrial function across New Zealand snail populations

The paper quantifies mitochondrial function variation in New Zealand snails across lakes and reproductive modes, finding lake-specific differences but limited effects of reproductive mode or sex.

Genetic variation for mitochondrial function in the New Zealand freshwater snail Potamopyrgus antipodarum

This study examines mitochondrial function variation across asexual lineages of Potamopyrgus antipodarum, revealing heritable differences that provide evolutionary insights.

Radical mutations persist longer in the absence of sex

The paper compares mutation removal rates between sexual and asexual lineages of Potamopyrgus antipodarum, finding that radical mutations are cleared faster in sexual lineages.
