Genetic studies of flat fruit forms confirm that peaches originated in China

, Aug. 16 (Xinhua Tan Yuanbin) China
Wuhan Botanical Garden, a new study on the genetic pathogenesy of peach flat fruit confirms that peaches originated in China. This study not only has theoretical significance for the formation of the mutant characteristics of cognitive fruit trees, but also provides support for the improvement of fruit shapes of fruit trees such as peaches.
is controlled by a single gene at the S-spot on chromosome 6, but its genetic pathogenetics were not previously known.
study of fruit tree molecular breeding discipline group of Wuhan Botanical Garden found that the position of large fragment chromosomes with a length of 1.7Mb downstream of S-bits was reversed to form the genetic basis for the formation of peach flat fruit shape.
, head of
research and a researcher at
Wuhan Botanical Garden, said that genotypes were found at the S-spot of wild near-edge species of peaches, and chromosomal inverting was present in Xinjiang peaches. The results not only confirm that peaches originated in China, but also provide important evidence for the inference that Xinjiang is the origin of domestication of cultivated peaches.
research results have recently been published in the international academic journal, the Journal of Plant Biotechnology.
