Main Results:

  • The actin gene of C. neoformans was successfully cloned and sequenced.
  • The gene is 1371 bp long, exists as a single copy, and has unique intron locations.
  • Phylogenetic analysis places the C. neoformans actin gene within a distinct fungal branch.

Conclusions:

  • The C. neoformans actin gene is evolutionarily conserved within fungi but possesses unique features.
  • This cloned gene is a valuable tool for further molecular and phylogenetic investigations.
  • Further research can leverage this genetic information to study C. neoformans pathogenesis.
