The definition,classification and evolution of citrus based on whole genome sequence information
Citrus is one of the most widely grown economic crops in the world.The wide sexual compatibility on inter-specific and even inter-generic level and the prevalent asexual variation of Citrus have led to the formation of the highly diverse and complex genetic background of citrus species.The classification of Citrus has also become one of the most challenging topics in plant science.In this study,we collected the most comprehensive genome sequencing data of Citrus so far for a precise analysis of the genetic composition and proportions of various varieties.We divided mandarin,pummelo and their hybrids into five types,and assigned a definition for each group.Then,using"Orah"and"Beni Madonna"as examples,we analyzed the genomic changes along with the breeding history of Citrus,and proposed the dispersal route of mandarin after domestication.We discussed the classification and origin of Citrus species and the genetic differences between"gan"and"ju",and also discussed the migration and evolution of mandarin.We proposed an objective classification of Citrus based on whole genome information,which provided a framework for the utilization of germplasm resources.
