This study identifies an XY sex chromosome system and sex-linked genes in the ivory palm, suggesting an independent evolutionary pathway for dioecy in palms.

The paper analyzes floral and reproductive traits across 361 flowering plant species to show that dioecy is linked to floral traits, while correlations with lifespan and dispersal are spurious.

This study examines the evolution of sex-biased gene expression during transitions to separate sexes in the Silene genus, showing male-biased genes emerge first and positive selection affects some SBGs.

The paper compares sex chromosomes in two palm species, finding convergent evolution with shared genes but independent origins.

The paper identifies male-specific nervous ganglia and LDPGs in Oithona nana, linking them to proteolysis and male-specific physiology.

The paper introduces SDpop, a method to detect sex-linked genes in natural populations using genotyped individuals, showing robust predictions with 5-10 individuals per sex.

The paper identifies the sex chromosomes of Cannabis sativa through segregation analysis and RNA-sequencing, revealing a highly degenerated Y chromosome and the oldest known plant sex chromosome system.

The paper investigates sexual dimorphism in Oithona nana by analyzing transcriptomic and protein-protein interaction data, finding male-specific enrichment in LNR domain proteins and pathways related to proteolysis and neurogenesis.
