“…In addition, the bitter kernel of P. sibirica has an amygdalin content of 3.5-7.6%, and it is also rich in vitamins, selenium, calcium, phosphorus, iron, potassium and other nutrients. Thus, this kernel is a raw material in traditional Chinese medicine [8]. The kernel consumption apricots have typical characteristic of large and sweet kernels.…”

The production and quality of apricots in China is currently limited by the availability of germplasm resource characterizations, including identification at the species and cultivar level. To help address this issue, the complete chloroplast genomes of Prunus armeniaca L., P. sibirica L. and kernel consumption apricot were sequenced, characterized, and phylogenetically analyzed. The three chloroplast (cp) genomes ranged from 157,951 to 158,224 bp, and 131 genes were identified, including 86 protein-coding genes, 37 rRNAs, and 8 tRNAs. The GC content ranged from 36.70% to 36.75%. Of the 170 repetitive sequences detected, 42 were shared by all three species, and 53–57 simple sequence repeats were detected with AT base preferences. Comparative genomic analysis revealed high similarity in overall structure and gene content as well as seven variation hotspot regions, including psbA-trnK-UUU, rpoC1-rpoB, rpl32-trnL-UAG, trnK-rps16, ndhG-ndhI, ccsA-ndhD, and ndhF-trnL. Phylogenetic analysis showed that the three apricot species clustered into one group, and the genetic relationship between P. armeniaca and kernel consumption apricot was the closest. The results of this study provide a theoretical basis for further research on the genetic diversity of apricots and the development and utilization of molecular markers for the genetic engineering and breeding of apricots.

Central Asia contains rich genetic resources for apricots. With its mountainous geography, Kyrgyzstan is the country where wild and cultivated apricot forms are preserved. The present study revealed genetic diversity and population structures in 91 apricot accessions from different regions of Kyrgyzstan. Fifteen simple sequence repeat (SSR) primers were used, capillary electrophoresis was performed, and the number of alleles per primer ranged from 4 to 11. A significant level of variation was determined among apricots originating from Kyrgyzstan. In the resulting dendrogram, all apricot accessions were divided into five groups, and the materials belonging to the northern and southern regions were grouped separately. At the same time, the population structure of apricots was analyzed. Accordingly, individuals have 0.80 or more membership coefficients; therefore, they are likely pure and non-admixed. There were 34 apricot accessions that have been determined as pure. The remaining 53 individuals had varying membership coefficients and were likely to be admixed by at least two subpopulations. This study is the most comprehensive research on Kyrgyzstan-origin apricots, providing vital information on their identification, preservation, and use in future research.
