Scientists reveal the origin and spread of apricots.

Original title: Scientists reveal the origin and spread of apricots
apricots are roseco li plants, distributed all over the world,
China
, Iran, Pakistan, Uzbekistan, Morocco, Algeria, Ukraine and
The United States
are the world's major production areas.
recently, Horticultural Research published online the latest results of the
Xinjiang
Agricultural University Professor Liao Kang task force, revealing the origin and spread of apricots.
the oasis areas of Kashgar, Hetian and Aksu on the peri-rim of the Ring Tarim Basin in southern Xinjiang, China, are the main apricot producing areas and the most abundant cultivated areas. Wild apricots in Yili and other places in northern Xinjiang are the remaining species retained in the late Third Century, which play an important role in the cultivation and domestication of the world apricots. The southern part of Xinjiang is only one mountain away from the Ili Valley, and there are several passages between the north and south of Tianshan. Geographically, the cultivation of apricots in southern Xinjiang is likely to have evolved from the spread of wild apricots in the Ili Valley.
Based on RAD-seq technology, this study analyzes the genetic diversity, population structure and genetic relationship of apricot species groups distributed in different geographical ecological groups, expounds the systematic development relationship between different ecological groups, and provides theoretical basis for further improvement and effective utilization of apricot species resources.
the study found that the apricot species of the Jung-Ili ecological group showed higher genetic diversity in the number of individual alleles, observational hybridity and nucleotide diversity. The Central Asian ecological group is domesticated by the Quanzhu-Ili ecosystem, and the population structure and gene flow of the North China eco-group and the European eco-group show a genetic background of Siberian apricots, which should be considered hybrid groups and are associated with Siberian apricots through sustained and extensive genetic flow.
researchers believe that common apricots originated in northwest China (Ili Valley), spread through Central Asia, and eventually spread to Europe. In addition, from the wild to the cultivation of apricot domestication process, the selective removal of the region covers different fruit-like genes, including sugar, aroma, acid, carotenoids and so on.
