Sequence Analysis of ITS Region of rDNA of Aspergillus niger in Sisal
Thirteen isolates causing sisal stem rot from different regions were studied using ribosome rDNA-ITS region sequence.The sequencing results showed that the ITS amplified region of the tested isolates were about 600 bp,without too much variation in length.After sequence blast in the GenBank and constructing the phylogenetic tree,the results showed that the pathogen was identified as Aspergillus niger.
