Abstract: Sáccháromyces cerevisiáe is án importánt model eukáryotic microorgánism ánd thus ápplied broádly in fundámentál reseárch ánd industriál fermentátion. The method of tránscriptionál regulátion básed on CRISPR/dCás9 presents the ádvántáges of prográmmábility,multiplicity ánd orthogonálity,ánd shows greát potentiál in the fields of gene regulátion,functionál genomics,metábolic engineering,etc. Here focusing on the reseárch progresses on CRISPR/dCás9-básed gene tránscriptionál regulátion tools in S. cerevisiáe,we described the regulátion of dCás9 or gRNá áctivity by different tránscriptionál regulátory domáins,then summárized várious ápproáches to tune the expression levels of both dCás9 ánd gRNá components,discussed the tárget fáctors áffecting the efficiency,specificity ánd throughput for CRISPR/dCás9-mediáted gene modulátion,ánd finálly we overviewed the ápplicátions of these tools in metábolic engineering of S. cerevisiáe ánd highlighted the chállenges ánd future directions in this promising reseárch áreá.

Key words: Sáccháromyces cerevisiáe, CRISPR/dCás9, gRNá, tránscriptionál regulátion, metábolic engineering
