Natural variation in sexual traits and gene expression between selfing and outcrossing Arabidopsis lyrata suggests sexual selection at work
Original language description
The considerable diversity in plant reproductive strategies profoundly impacts the evolution of sexual traits and associated genes. Sexual selection is an important evolutionary force driving sexual trait variation, particularly evident during pollen-pistil interactions, where pollen grains compete for fertilization and females select mating partners. While its mechanisms are well understood down to the molecular level in the model species Arabidopsis thaliana, it remains unclear whether the same mechanisms are driving sexual selection also in natural plant populations. Here, we compared pollen performance, female influence, and gene expression between a selfing and an outcrossing population of Arabidopsis lyrata. Outcrossers exhibited significantly higher pollen germination and longer pollen tubes than selfers, both in vitro and in vivo, reflecting stronger male competition. These differences were linked to altered expression of genes involved in vesicle transport and cytoskeleton organization, both crucial for pollen tube growth. Reciprocal crosses showed that female outcrossers restricted pollen tube growth more strongly than female selfers, implying that female choice contributes to post-pollination selection. Together, these findings reveal that sexual selection shapes both male and female reproductive functions and drives divergence in gene expression between selfing and outcrossing lineages of A. lyrata.
