Spotlight Articles Selected by the Editors of Plant Disease, Phytopathology, and Molecular Plant-Microbe Interactions (MPMI) Plant Disease Editor’s Pick What factors influence the latent periods of foliar fungal pathogens? The latent period for Septoria blotch, caused by Septoria tritici on wheat, is 11 to 42 days. M. Henze, M. Beyer, and colleagues used meteorological data from 39 sites to calculate a field estimate of 20 days. Read their article, Characterizing Meteorological Scenarios Favorable for Septoria tritici Infections in Wheat and Estimation of Latent Periods to see how the latent period changed with temperature, latitude, and precipitation. Phytopathology Editor’s Pick The development and spatial spread of exotic and potentially devastating soybean rust in the southeastern U.S. in 2005 and 2006 was analyzed using USDA records. The disease developed late both years, which was attributed to slow build-up of the fungus on the overwintering host, kudzu, and a narrow window of opportunity for disease establishment during reproductive development of soybean. MPMI Editor’s Pick In the November issue of MPMI, Halim et al. studied the response of potato plants that cannot accumulate salicylic acid to Phytophthora infestans. As previously reported, there was little difference in lesion size. However, pathogen growth was greatly enhanced in the nonaccumulating plants.
