Abstract: Although the genetic background of cucumber is narrow,its sex types are diverse and abundant.Therefore, cucumber is the model plant for sex differentiation study.From morphology to cytology and from classical genetics to molecular biology,researchers have done a lot of important researches on cucumber sex differentiation.It was revealed that the genetic basis of major sex types and the molecular regulation mechanism of ethylene metabolic pathway as main line.But the mechanism of sex differentiation of cucumber flowers and diversification of the sex types still couldn't be completely elucidated.In recent years,the rapid development of genomics,epigenetics and miRNA provided new perspectives and technologies for deeply clarifying the mechanisms of sex differentiation.The further comprehensive analyses would provide theoretic and technical support for regulating sex differentiation in cucumber cultivation of high and stable yield and the molecular breeding for sex type improvement of cucurbitaceae crops.

Key words: Cucumber, Sex differentiation, Genetic basis, Molecular regulation mechanism, Epigenetics, miRNA
