Project description:The transcript profiles of Nesterenkonia sp. AN1 grown at 5 ºC (Cold) and 21 ºC (Topt) were acccessed to evaluate the cold reposnse of this Antarctic Nesterenkonia strain. The strain was grown in triplicates at the optimum growth temperature of 21 ºC and a test temperature of 5 ºC. Total RNA was extracted from two replicate samples for each treatment condition and the total RNA was enriched for mRNA. RNA-seq was done using Illumina Miseq platform at Inqaba Biotech, South Africa. The reads were mapped against the genome sequence of Nesterenkonia sp. AN1 (obtained from NCBI database) and assesed for differeential gene expression using CLC Genomics Workbench 7.5.
Project description:In the absence of light, the heterotrophic microalga Crypthecodinium cohnii accumulates lipids rich in docosahexaenoic acid (DHA). However, limited genetic data restricts understanding of its metabolism, especially DHA synthesis with ethanol. Next-generation sequencing identified numerous transcripts for fatty acid and carbohydrate production. qRT-PCR confirmed increased expression of genes linked to energy, carbohydrate, lipid, terpenoid, and polyketide metabolism. Upregulation of genes in ethanol metabolism, fatty acid synthesis, glycerophospholipid, and pyruvate pathways raised acetyl-CoA and key metabolite precursors.
