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.
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 M-NM-^T9 elongase/M-NM-^T8 desaturase pathway, and is derived from Yarrowia lipolytica ATCC#20362. A six chip study using total RNA recovered from three separate cultures of Yarrowia lipolytica Y4184Ura+ strains and three separate cultures of Y4184 snf1 mutant strains in which YlSNF1 gene is deleted entirely. Each chip measures the expression level of 6708 genes from Yarrowia lipolytica ATCC#20362 with fourteen 24-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.
Project description:Total RNA versus genomic DNA hybridization on custom arrays designed for all Yarrowia lipolytica genes Total RNA was collected in mid-log phase from Yarrowia lipolytica cells grown in rich medium (abbreviated CM, in house recipe). RNA was then converted to cDNA, Cy3-labeled and hybridized competitively against Cy5 labeled genomic DNA from Yarrowia lipolytica.
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.
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.
Project description:In the frame of a multispecies project, Yarrowia lipolytica cells were treated with 10 mM sodium selenite. Cells were collected 10, 20, 30, 40, 50, 60, 70 and 80 minutes after the treatment and their transcriptomes were compared to those of mock-treated cultures. Four independent biological replicates were performed.
