The species-specific primer CaInt2 in conjunction with ITS4 primer amplified a 490 bp fragment from genomic DNA of tomato isolates, and the reference isolate of C. acutatum CBS 294.67, but not from DNA of C. gloeosporioides reference isolate (Figure 5a). In contrast, DNA of the tomato isolates, as well as the reference C. acutatum, were not amplified by the speciesspecific primer CgInt in conjunction with ITS4 primer, whereas a 450 bp fragment was amplified only from DNA of reference C. gloeosporioides CBS 516.97 (Figure 5b). No PCR products were produced with water controls in any of the reactions.
