Cloning and Sequencing Analysis of a Laccase Gene from Fungus

Abstract:

Effect of several different methods on the DNA extraction from Pycnoporus sanguineus were compared in this study.Degenerate primers were designed according to the fungal laccase condervation sequences which was registered on GenBank,.A 1084bp laccase gene fragment was amplified by using genomic DNA from Pycnoporus sanguineus as template.According to the BLAST results,we found that the sequence presented a very high match with the laccase gene from Pycnoporus and shared considerable homology of above 99%.The alignment of amino acids shared considerable homology of above 88%.Therefore,the genomic DNA should be Pycnoporus.
