This study investigates cis-regulation of gene expression between sexes and life stages in Rumex hastatulus using eQTL mapping, finding stronger shared genetic architecture between sexes than between life stages.

The paper develops a framework to analyze multispecies synteny data and applies it to Rumex, finding accelerated syntenic evolution linked to transitions to dioecy and XY sex determination.

The paper investigates Y chromosome degeneration in Rumex hastatulus, finding widespread underexpression of Y genes and no evidence of early dosage compensation.

This study examines how floral asymmetry affects pollen transfer and mating outcomes, finding that dimorphic enantiostyly enhances outcrossing but increases stochasticity in pollen transfer.

This study identifies the genetic architecture of the S-locus supergene in tetraploid Schizomussaenda henryi, revealing hemizygous genes, gene duplication, and the role of auxin signaling in style length regulation.

The paper examines genomic signals of selection across life stages in plants, finding stronger purifying selection on unbiased genes and synergistic pleiotropy rather than antagonistic pleiotropy.

This study identifies that floral handedness in Cyanella alba is determined by phyllotactic spiral direction and auxin-induced differential cell elongation, not genetics.

The paper examines latitudinal clines in flowering phenology of Lythrum salicaria, finding earlier flowering and bet-hedging strategies at higher latitudes linked to adaptive evolution during invasion.

This study characterizes sex differences in recombination landscape in Rumex hastatulus, showing strong male-specific recombination suppression and its potential role in sex chromosome evolution.
