NON-AUXOTROPHIC SELECTION MARKER

摘要

A non-auxotrophic selection marker located in a gene cluster encoding a metabolite for an organism, such as a fungus, lacking said marker is provided. The selection marker gene can be used to detect and confirm the introduction of foreign genes without the use of exogenous drug-resistant genes to facilitate transformant selection. The selection marker gene can be applied to detect the presence of fungal infection and predict the likelihood of the development of disease or allergic response at an early stage so that medical intervention may be sought.
