Abstract:

Endophytic fungal strains were classified according to the differentially physiological and biochemical responses of grape cells during their co-culturing with endophytic fungi,which may be conducive to screening endophytic fungal resources with varied application values. Grape callus(Vitis vinifera L. cultivar:Gamay)and 47 endophytic fungal strains from 18 genera isolated from grape varieties Rose honey,Cabernet Sauvignon and Xiahei were chosen as experimental materials to construct endophytic fungi-grape cell contacted co-culture system. Further the physiological and biochemical effects of these endophytic fungal strains on grape cellular,growth,anthocyanin contents,phenylalanine ammonia-lyase(PAL)activities and others were analyzed. Ours results indicated that different endophytic fungal strains initiated different degrees of impacts on the co-cultured grape cells in growth,anthocyanin contents and PAL activity. Among all those used endophytic fungal strains,20 conferred less damages to grape cells,6 significantly promoted the co-cultured grape cells in growth,11 significantly promoted the co-cultured grape cellular PAL activity,and 5 promoted the co-cultured grape cells’ anthocyanin contents. Beside the development of candidate endophytic fungal strains,this research provided a methodology for purposely screening candidate endophytic fungal resources.
