Colletotrichum gloeosporioides: An Anthracnose Causing Pathogen of Fruits and Vegetables

Relying on morphology of appressoria and conidiomata conidia dimensions, three biological groups within the C. gloeosporioides complex were determined.

“Relying on morphology of appressoria and conidiomata conidia dimensions, three biological groups within the C. gloeosporioides complex were determined (Sharma and Kulshrestha, 2015).”

On the molecular level, phylogenetic relationships in the Colletotrichum spp. have been successfully identified through sequencing in the internal transcribed spacers 1 and 2 (ITS1 and ITS2) regions and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene.

“On the molecular level, phylogenetic relationships in the Colletotrichum spp. have been successfully identified through sequencing in the internal transcribed spacers 1 and 2 (ITS1 and ITS2) regions and glyceraldehyde-3-phosphate dehydrogrenase (GAPDH) gene (Sharma and Kulshrestha, 2015; Pardo-De la Hoz et al., 2016).”

C. gloeosporioides is typically dormant in the dry season, especially during extremes of temperature, low humidity, and sunlight.

Optimal growth of C. gloeosporioides is favored at high humidity, pH range of 5.8 to 6.5, and temperature of 25-28°C.

“However, optimal growth of the pathogen is favored at high humidity, pH range of 5.8 to 6.5, and temperature of 25–28°C (Sharma and Kulshrestha, 2015).”

The SL's antifungal activity against Colletotrichum gloeosporioides indicates a potential application as a food preservative against post-harvest decays of apple caused by this pathogen.

“In our study, the promising activity against Colletotrichum gloeosporioides indicates a potential application as food preservative against post-harvest decays of apple caused by this pathogen [53].”
