I work on some stress tolerance genes from plants. I clone those genes in pYES2 yeast expression vector and transform in to INVSc1 yeast strain to perform stress tolerance assay using different abiotic stress factos. Some months back I lost the viability of the yeast strain and now need those INVSc1 strain. Is any one know about yeast strain which I can use like INVSc1 yeast strain for stress tolerance experiment? I would really helpful to know about this.

Thanks
