First Report of Bacterial Blight of Pennycress Caused by in Wisconsin.

In May 2023, pennycress (, L.) lines undergoing seed production in the Walnut Street Greenhouse at the University of Wisconsin-Madison displayed symptoms of chlorosis and black necrotic leaf spots (Fig. S1-A).

Optimization of an isothermal recombinase polymerase amplification method for real-time detection of Potato virus Y O and N types in potato.

Potato virus Y (PVY) is a global challenge for potato production and the leading cause of seed crop downgrading and rejection for certification. Accurate and timely diagnosis is key to effective control of PVY. Here we optimized the isothermal recombinase polymerase amplification (RPA) for accurate detection of different PVY O and N types that were tested, present in different tissues of potato plants including tubers with a primer set that specifically targets the highly conserved pipo region within the viral genome.
