The Y1979 strain of yeast was transformed with the insertion of the coding sequence for Farnesene Synthase to produce beta-farnesene from the fermentation of sugar cane. This is a long chain hydrocarbon that can be used as a biofuel.

The term “Recipient organism” refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas “Parental organisms” refers to those that were involved in cross breeding or cell fusion.

Additional Information
Saccharomyces cerevisiae strain Y1979 is in a diploid state, resulting in the blocking of sexual reporoduction between the haploid forms α and a. Additionally, genes STE5 and IME1, which are required for sporulation and for early sporulation-specific genes expression, were inactivated in this strain therefore hindering production of haploid ascospores and reducing to insignificant levels the likelihood that the yeast sexually reproduces with other naturally occurring yeasts, including laboratory lineages.

These modifications, coupled with alterations to the mevalonate pathway, make this strain highly dependent on specific conditions for proliferation and maintenance, warranting difficulty for the organism in colonizing the environment by invasion or competition with the natural microbiota.
