RenSeq of Silphium integrifolium Reveals a Biotic Gradient for Disease Resistance

This study uses RenSeq to analyze R genes in Silphium integrifolium across a rainfall gradient, finding a positive correlation between precipitation and R gene count.

Genetic evidence for environment-dependent hybrid incompatibilities in threespine stickleback

The paper tests for environment-dependent hybrid incompatibilities in threespine stickleback by comparing excess heterozygosity in F2 hybrids raised in different environments.

Development of first linkage map for Silphium integrifolium (Asteraceae) enables identification of sporophytic self-incompatibility locus

The paper develops a linkage map for Silphium integrifolium to identify the sporophytic self-incompatibility locus, successfully mapping it and identifying potential gene candidates.

Nonself-recognition-based self-incompatibility canalternatively promote or prevent introgression

The paper models S-allele evolution in two populations with gene flow, finding that nonself-recognition-based self-incompatibility often disfavors introgression or leads to S-allele replacement.

Reconstructing the history and biological consequences of a plant invasion on the Galapagos islands

This study uses population genomics to trace the invasion of wild tomato on the Galapagos Islands, revealing hybridization with endemic species and its impact on fruit color evolution.

Widespread imprinting of transposable elements and young genes in the maize endosperm

The paper identifies widespread maternal expression of genes and transposable elements in maize endosperm using whole genome assemblies from reciprocal crosses, revealing imprinted expression patterns and fused transcripts.

The effect of autopolyploidy on population genetic signals of hard sweeps

This study investigates how autopolyploidy affects population genetic signals of hard sweeps using coalescent simulations.

Diversification or collapse of self-incompatibility haplotypes as a rescue process

The paper models the dynamics of self-incompatibility haplotypes in angiosperms, showing how new haplotypes can increase or decrease in number based on gene conversion rates and population size.

The role of gene flow in rapid and repeated evolution of cave related traits in Mexican tetra, Astyanax mexicanus

This study shows that gene flow plays a significant role in the rapid evolution of cave-related traits in Mexican tetra, challenging the classic hypothesis of disuse and drift.
