초록
Taxonomy includes classification, nomenclature, and identification. Identification assignsunknown fungi to species based on their strain characteristics. Traditionally, fungal taxonomyrelied on morphological, physiological, and biochemical traits. However, advancements inmolecular phylogeny, especially multilocus sequence analysis (MLSA), have revolutionizedfungal taxonomy. MLSA combines phylogenetic and genetic approaches. Although effective,MLSA may not fully reflect biodiversity or distinguish between closely related species. Polyphasic taxonomy integrates genotypic, phylogenetic, chemotaxonomic, and phenotypicdata into a consensus classification system. Polyphasic taxonomy was first applied toRhodotorula glutinis in 2001 and is now widely accepted. Phenotypic traits, such as proteinprofiles and chemotaxonomic markers, analyzed using techniques such as matrix-assistedlaser desorption ionization-time of flight mass spectrometry, are effective for yeast andfilamentous fungi. Genotypic data from DNA/RNA sequencing, compared with data fromdatabases such as Index Fungorum and MycoBank, aids species identification and synonymverification. Despite its practicality, the polyphasic approach lacks strict guidelines, resultingin varied interpretations.
