英文摘要	Date palm (Phoenix dactylifera), one of the most ancient crops, is grown commercially in >30 countries. Using whole plastome assemblies, phylogenetic analyses revealed that cultivated date palm accessions share the same clade with Phoenix sylvestris, Phoenix pusilla and Phoenix acaulis, which are native to the Indian subcontinent, and Phoenix caespitosa that is native to the Arabian Peninsula and the deserts of Somalia. Analysis of genetic diversity and genetic relationships among date palm accessions from 13 producing countries involved 195 date palm accessions that were genotyped at 19 microsatellite loci. Extensive genetic diversity was observed, with many accessions heterozygous for most markers in this clonally propagated crop. The average number of alleles per locus (42.1), expected heterozygosity (0.8), observed heterozygosity (0.47) and fixation indices (F-ST = 0.42) demonstrated substantial genetic diversity and population structure. Iraqi accessions were found to have the richest allelic diversity, and the most private alleles. The model-based Bayesian method indicated that these accessions could be broadly divided into two structure groups, one group with predominantly African accessions and another predominantly Asian. Some germplasm, especially from Tunisia and Iraq, deviated from this generalization. Many accessions in the STRUCTURE-derived groups were found to be genetic admixtures, with gene flow between Asian and African groups. Indian and Pakistani date palms were found to be most closely related to North African germplasm. Copyright (C) 2018 Kunming Institute of Botany, Chinese Academy of Sciences.
