Molecular detection of Colletotrichum lindemuthianum in bean seed samples

Abstract: Colletotrichum lindemuthianum is the causal agent of anthracnose in common bean, and infected seeds are the most typical propagation form of the disease. Thus, using common bean seeds free of C. lindemuthianum is crucial to managing this pest, as well as employing fast and accurate detection techniques to ensure high seed quality. In this study, both conventional and quantitative PCR techniques (cPCR and qPCR) were used for the detection and quantification of C. lindemuthianum in samples of common bean seeds. … Show more

“…Other example, cPCR and qPCR techniques were effective in detecting Colletotrichum lindemuthianum in beans seeds. It was possible using cPCR to detect the fungus in seed samples with 10% of incidence and with 0.25% incidence by qPCR technique (Gadaga et al, 2018).…”

“…Real time PCR (qPCR) amplification was done with the genomic DNA isolated from the fungal colonies, specific primers previously described in the literature for the detection of C. lindemuthianum were used (Gadaga et al, 2018;Halvorson et al, 2021). The amplification was performed using a Rotor Gene Q cycler (Qiagen, Hilden, Germany) with initial condition at 95°C for 3 min, followed by 95°C for 10 s, 55°C for 10 s, 72°C for 20 s, 40 cycles, and at 72°C for 5 min.…”

“…A seguir, 100 µl da suspensão são plaqueadas em meio de cultura semi-seletivo XCP1, constando de 4 placas/diluição. As placas são incubadas a 28 °C por 3 dias e, em seguida, conta o número de UFC/ml por placa (Goszczynska et al, 1998;Brasil, 2009). A identicação preliminar das colônias no meio XCP1 são amarelas, mucóides, lisas, convexas e circundadas por zonas de hidrólise de amido.…”
