摘　　要：It has long been recognized that natural selection during the haploid gametophytic phase of the plant life cycle may have widespread importance for rates of evolution and the maintenance of genetic variation.Recent theoretical advances have further highlighted the significance of gametophytic selection for diverse evolutionary processes.Genomic approaches offer exciting opportunities to address key questions about the extent and effects of gametophytic selection on plant evolution and adaptation.Here,we review the progress and prospects for integrating functional and evolutionary genomics to test theoretical predictions,and to examine the importance of gametophytic selection on genetic diversity and rates of evolution.There is growing evidence that selection during the gametophyte phase of the plant life cycle has important effects on both gene and genome evolution and is likely to have important pleiotropic effects on the sporophyte.We discuss the opportunities to integrate comparative population genomics,genome-wide association studies,and experimental approaches to further distinguish how differential selection in the two phases of the plant life cycle contributes to genetic diversity and adaptive evolution.
