<title language="por">Amplification of the cap20 pathogenicity gene and genetic characterization using different markers molecular in Colletotrichum gloeosporioides isolates
Studies were performed to analyze the genetic characterization using RFLP-ITS and Intron (primer EI1) markers and the amplification of the cap20 pathogenicity gene by PCR in Colletotrichum gloeosporioides isolates of different hosts plant. The genetic variability was accessed using RFLP-ITS and Intr...
