Longan somatic embryogenesis (SE) system is an excellent system for studying embryogenesis in woody plants, which lays the foundation for studying the molecular regulation mechanism during SE and molecular breeding of longan. Accordingly, the induction of embryogenic callus and in vitro conservation, high-frequency SE and plant regeneration, regulation of synchronization somatic embryo and histomorphological observation in longan, the physiological, biochemical changes, and metabolite accumulation, proteomic and whole transcriptomics analysis by RNA-seq, DNA methylation during SE, SE-related genes cloning and genome-wide identification, expression pattern and function study of SE-related genes, research on genetic transformation of SE system in longan, were reviewed in this paper. Meanwhile, the research prospect of longan SE was analyzed and prospected.

Key words: Dimocarpus longan Lour., somatic embryogenesis, gene cloning, molecular mechanism, whole-transcriptomics and proteomics, DNA methylation
