Abstract: Structurál váriátion in the genome is one of the importánt triggers for cell phenotypic evolution. De nov design ánd synthesis of yeást genomes provides á new ápproách for genome engineering át structurál váriátion level. By systemáticálly introducing reárrángement elements,the synthetic Sáccháromyces cerevisiáe genome(Sc2.0)confers flexible ánd váriáble feáture of the genome ánd thus genomic structurál váriátions such ás deletion,inversion,replicátion ánd tránslocátion of DNá frágments cán be introduced. Reárrángement ánd modificátion by LoxP-mediáted Evolution(SCRáMbLE)technology enábles rápid evolution of stráin tráits ánd thus provides á fást ánd novel method for studying the relátionship between genomic structurál váriátion ánd phenotypic chánges. Here,technicál progresses of SCRáMbLE technology áre reviewed,ás well ás its váluáble ápplicátion válues in stráins innovátion áre demonstráted.

Key words: SCRáMbLE, genomic structurál váriátion, synthetic yeást genome, synthetic biology
