Real-Time PCR Assay for the Diagnosis and Quantification of Co-infections by and in Sweet Potato.

Foot rot disease caused by (formerly ) has become a major concern for the production of sweet potato [ (L.) Lam.] in Japan.

Community Analysis of Root- and Tuber-Associated Bacteria in Field-Grown Potato Plants Harboring Different Resistance Levels against Common Scab.

Eight genotypes of potato plants with different resistance levels against common scab were grown in a field infested with Streptomyces turgidiscabies. DNA was extracted from the roots, tubers, and rhizosphere soils of each of the eight genotypes at the flowering stage, and the quantity of S. turgidiscabies genomic DNA was assessed by real-time PCR using a TaqMan probe.
