Undoing the 'nasty: dissecting touch-sensitive stigma movement (thigmonasty) and its loss in self-pollinating monkeyflowers

The paper investigates the genetic and molecular basis of stigma closure in monkeyflowers, identifying QTLs and gene expression patterns associated with this trait and its loss in self-pollinating species.

Phage-encoded ribosomal protein S21 expression is linked to late stage phage replication

The paper investigates the expression of the bS21 gene in phages, finding it is active during late-stage replication and may aid in phage particle assembly.

Population genomic consequences of novel life history and mating system adaptation to a geothermal soil mosaic in yellow monkeyflowers (Mimulus guttatus)

This study examines genetic and phenotypic variation in Mimulus guttatus across a geothermal soil mosaic, finding that life history and mating system adaptation do not necessarily lead to speciation without geographic barriers.

Selfish chromosomal drive shapes recent centromeric histone evolution in monkeyflowers

The paper tests the selfish centromere model in Mimulus guttatus, showing co-evolution between a driving centromere and a kinetochore protein, with implications for fitness and molecular divergence.

Ancient and recent introgression shape the evolutionary history of pollinator adaptation and speciation in a model monkeyflower radiation (Mimulus section Erythranthe)

This study uses phylogenomic analysis to show that introgression, not speciation, explains pollination syndrome convergence in Mimulus species.

Quantitative trait locus mapping reveals an independent genetic basis for joint divergence in leaf function, life-history, and floral traits between scarlet monkeyflower (Mimulus cardinalis) populations

This study maps quantitative trait loci (QTLs) for leaf, life-history, and floral traits in Mimulus cardinalis populations, finding no genetic coordination across trait categories and suggesting environmental selection drives trait syndromes.

Wide distribution of phage that infect freshwater SAR11 bacteria

The paper identifies and characterizes phages infecting Fonsibacter, showing their global distribution and ecological impact on freshwater microbial communities.

Selection, linkage, and population structure interact to shape genetic variation among threespine stickleback genomes

This study examines how selection, linkage, and population structure shape genetic variation in threespine stickleback genomes across marine and freshwater habitats.

Clades of huge phage from across Earth’s ecosystems

The paper identifies major clades of large phage genomes across diverse ecosystems and highlights their expanded genetic repertoires and potential functional roles.

Complex pleiotropic genetic architecture of evolved heat stress and oxidative stress resistance in the nematode Caenorhabditis remanei

This study investigates the genetic architecture of heat and oxidative stress resistance in C. remanei, finding polygenic and largely independent genetic bases for these traits.

Extreme copy number variation at a tRNA ligase affecting phenology and fitness in yellow monkeyflowers

This study identifies a tRNA ligase gene with extreme copy number variation in yellow monkeyflowers, showing its impact on phenology, fitness, and stress response across different environmental conditions.

Ancient genomic variation underlies repeated ecological adaptation in young stickleback populations

The paper identifies ancient genomic variation underlying repeated ecological adaptation in stickleback populations, showing that standing genetic variation from geological timescales drives rapid local adaptation.
