Comparative transcriptome analysis of yeast expressing the fungal desaturases

ABSTRACT: To study how the presence of PUFAs influences central cellular processes, and in order to perform lipidome, transcriptome and molecular studies we decided to use yeast as a model organism. We therefore co-expressed Δ12-desaturase and Δ6- desaturase genes from Mucor rouxii in S. cerevisiae with the objective to obtain a yeast strain that contains PUFAs, especially linoleic acid (LA, C18:2Δ9,12) and γ-linolenic acid (GLA, C18:3Δ6,9,12), in its membranes. The resulting yeast strain was analyzed in details in order to quantify the fluxes through the fatty acid biosynthetic pathways and the genome-wide transcriptional response to production of LA and GLA. Three recombinant yeasts were constructed and grown in glucose-limited condition. Steady-state cultures were harvested for RNA extraction and
