  2. Auxotrophy - Wikipedia

    en.wikipedia.org/wiki/Auxotrophy

    In genetics, a strain is said to be auxotrophic if it carries a mutation that renders it unable to synthesize an essential compound. For example, a yeast mutant with an inactivated uracil synthesis pathway gene is a uracil auxotroph (e.g., if the yeast Orotidine 5'-phosphate decarboxylase gene is inactivated, the resultant strain is a uracil ...

  3. URA3 - Wikipedia

    en.wikipedia.org/wiki/URA3

    URA3 is often used in yeast research as a "marker gene", that is, a gene to label chromosomes or plasmids. URA3 encodes Orotidine 5'-phosphate decarboxylase (ODCase) , which is an enzyme that catalyzes one reaction in the synthesis of pyrimidine ribonucleotides (a component of RNA ).

  4. Saccharomyces Genome Database - Wikipedia

    en.wikipedia.org/wiki/Saccharomyces_Genome_Database

    In the peer-reviewed literature report, experimental results on function and interaction of yeast genes are extracted by high-quality manual curation and integrated within a well-developed database. The data are combined with quality high-throughput results and posted on Locus Summary pages which is a powerful query engine and rich genome browser.

  5. Candida albicans - Wikipedia

    en.wikipedia.org/wiki/Candida_albicans

    Next to the above-mentioned selection makers a few auxotrophic strains were generated to work with auxotrophic makers. The URA3 marker (URA3 blaster method) is an often-used strategy in uridine auxotrophic strains; however, studies have shown that differences in URA3 position in the genome can be involved in the pathogeny of C. albicans.

  6. Nutritional yeast - Wikipedia

    en.wikipedia.org/wiki/Nutritional_yeast

    Nutritional yeast (also known as nooch [4]) is a deactivated (i.e. dead) yeast, often a strain of Saccharomyces cerevisiae, that is sold commercially as a food product. It is sold in the form of yellow flakes, granules, or powder, and may be found in the bulk aisle of natural food stores .

    The food type most likely to have these claims was plant-based meat analogues, with almost 70% of these products making this claim. About 60% of products with protein claims had protein added to them.

  8. Genetic transformation - Wikipedia

    en.wikipedia.org/wiki/Genetic_transformation

    Another method of selection is the use of certain auxotrophic markers that can compensate for an inability to metabolise certain amino acids, nucleotides, or sugars. This method requires the use of suitably mutated strains that are deficient in the synthesis or utility of a particular biomolecule, and the transformed cells are cultured in a ...
