Auxotrophy - Wikipedia
网页Auxotrophy (Ancient Greek: αὐξάνω "to increase"; τροφή "nourishment") is the inability of an organism to synthesize a particular organic compound required for its growth (as defined by IUPAC). An auxotroph is an organism that displays this characteristic; auxotrophic is the corresponding adjective.

6.3: Auxotrophs and selective media - Biology LibreTexts
网页For example, because the BY4742 strain carries mutations in the HIS3, LEU2, LYS2 and URA3 genes, the strain will only grow in media containing histidine, leucine, lysine and uracil. Auxotrophic strains have many uses in genetics.
The social network of microorganisms — how auxotrophies
网页2018年3月29日 · Most microorganisms are auxotrophs, thus relying on external nutrients for growth, including the exchange of amino acids and vitamins. Currently, we lack a deeper understanding of auxotrophies in...
Auxotrophy - an overview | ScienceDirect Topics
网页Auxotroph. A cellular organism that cannot synthesize an organic compound required for growth, usually an amino acid, due to a mutation or deletion of a gene required for its synthesis. This organism can only grow if the missing amino acid is provided in the environment or if transformed with a plasmid that contains the missing gene. Drug ...

Auxotrophy - an overview | ScienceDirect Topics
网页Auxotrophs are commonly used in filamentous fungi transformation, which requires a gene, or the selectable marker, that restores prototrophy. However, the bottleneck of using auxotrophy as a selectable marker is that a starting mutant strain is needed.
