Functional genomics for the oleaginous yeast Yarrowia lipolytica

Project description:Oleaginous yeasts are valuable systems for biosustainable production of hydrocarbon-based chemicals. Yarrowia lipolytica is one of the best characterized of these yeast with respect to genome annotation and flux analysis of metabolic processes. Nonetheless, progress is hampered by a dearth of genomewide tools enabling functional genomics. The Hermes DNA transposon was expressed to achieve saturation mutagenesis of the Y. lipolytica genome. Over 535 thousand independent insertions were identified by next-generation sequencing. Poisson analysis of insertion density classified ~22% of genes as essential. As expected, most essential genes not only have homologues in Saccharomyces cerevisiae and Schizosaccharomyces pombe, but the majority of those are also essential. As an obligate aerobe, Y. lipolytica has significantly more respiration - related genes that are classified as essential than do S. cerevisiae and S. pombe. The findings provide insights into biosynthetic pathways, compartmentalization of enzymes, and distinct functions of paralogs. Contributions of nonessential genes to fitness were determined in log growth cultures with glucose and glycerol carbon sources. Fluorescence-activated cell sorting identified mutants in which lipid accumulation is increased. Biological contributions of genes to growth were used to evaluate two recent genome-scale models Y. lipolytica metabolism. This study is the first functional genomic analysis of an oleaginous yeast and provides an important resource for modeling and bioengineering of Y. lipolytica.

Transcriptome change in response to ochratoxin A (OTA) in Yarrowia lipolytica Y-2

Project description:The yeast Yarrowia lipolytica Y-2 shown the capability to degrade OTA by the intracellular enzymes. However, the enzymes which risponsible for the degradation process was unkonown. Transcriptome change in response to mycotoxin OTA was analyzed. The molecular mechanism of Yarrowia lipolytica Y-2 withstand OTA was revealed.

Yarrowia lipolytica fed-batch biolipid production.

Project description:Time-course transcriptomic profilling of the oleaginous yeast Yarrowia lipolytica, during a controlled fed-batch. A nitrogen limitation was applied during the course of the fed-batch to initiate de novo biolipid synthesis. Dual staining, one replicate per slide. On each slide, a time point sample and a reference sample are spotted. Reference samples were obtained by pooling the RNAs from the time-course samples.

Yarrowia lipolytica biolipid production during D-stat setup. [Part 2]

Project description:Second part of the time-course transcriptomic profilling of the oleaginous yeast Yarrowia lipolytica, obtained during a controlled decellerostat (D-stat) setup. A nitrogen limitation was applied during the course of the D-stat to initiate and control de novo biolipid synthesis. Yarrowia lipolytica Agilent microarray, one-color staining. Each time sample was spotted in triplicate (except for sample 26, for which a technical replicate of replicate r1 was performed).

Transcriptomic study revealing the effect of thiamin on the morphology of Yarrowia lipolytica

Project description:A comparison between Y. lipolytica growth in a Synthetic agar Medium not containing THiamin (SM TH-) to its growth in a Synthetic agar Medium supplemented with THiamin (SMTH+) at day 8 of the culture. This study allowed us to discover the effect of thiamin on the growth and the morphology of Y. lipolytica The transcriptomic study was carried out using Agilent 8X15k slides with a custom oligoset designed by V. Loux using the Yarrowia lipolytica ORFeome extracted from genolevures database

Expression analysis of Yarrowia lipolytica Y4184 snf1 mutant

Project description:Investigation of whole genome gene expression level changes in a Yarrowia lipolytica Y4184 snf1 mutant, compared to the Y4184U+. The Y4184 is an engineered strain to produce eicosapentaenoic acid (EPA) via expression of a Δ9 elongase/Δ8 desaturase pathway, and is derived from Yarrowia lipolytica ATCC#20362.
