The Nature Journal of Huazhong Agricultural University discovers somatic variation that affects the sourness of sweet orange fruit

Nanhu News Network (Correspondent Wang Lun) On June 17, the research group of Xu Qiang from the College of Horticulture and Forestry, Huazhong Agricultural University discovered somatic mutations that affect the sourness of sweet orange fruits

Most fruit trees propagate vegetatively, and bud mutation breeding based on somatic mutation has become an important breeding method for fruit trees

Citric acid is a key factor in the flavor of citrus fruits.

In order to analyze the genetic basis of the somatic variation of sweet oranges and to dig out the key genes that affect the sourness of the fruit, the study adopted the strategy of bud mutation population combined with genomics to improve the range and accuracy of somatic cell prediction

Sweet oranges have spread from China through the Maritime Silk Road and the Ancient Tea-Horse Road to other places in history.

Postdoctoral fellow of the College of Horticulture and Forestry Wang Lun, PhD students Huang Yue and Liu Ziang are the co-first authors of the paper, Professor Xu Qiang is the corresponding author of the paper, and Academician Deng Xiuxin participated in the guidance of the project

Abstract

Somatic variations are a major source of genetic diversification in asexual plants, and underpin clonal evolution and the breeding of asexual crops.
