Published: November 2016

A quantitative PCR method was developed for detecting Fusarium graminearum growing in maize callus. Fungal DNA was detected 12h after inoculation (detection limit, 0.2pg) and was correlated with visual ratings. The method effectively quantified fungal growth in callus overexpressing a peroxidase gene conferring fungal resistance.
