Methods for modification of target nucleic acids. The method involves a construct in which guide RNA is covalently linked to donor RNA (fusion NA) to be introduced into the target nucleic acid by homologous recombination and is based on the introduction of a nuclease, e.g. CRISPR or TALEN, into the cell containing the target nucleic acid. The fusion NA may be introduced as a DNA vector.

The invention relates to the field of microbiology, more particularly to fermentation technology. Yeast fermentation, particularly production of bio-based compounds starting from second generation carbon sources is often hampered by the presence of inhibitory chemicals. This application provides means and methods to overcome the negative effect of fermentation inhibitors, more particularly by providing chimeric genes and yeast strains comprising them that are tolerant to these inhibitors.
