The wheat seed phytomicrobiome as a potential source of resistance to the fungal disease, Fusarium head blight
… according to plant developmental stages or maturity plant, location, and host genotype, but not by variety or maturity group. First, comparing plants at the pre-flowering versus mature grain-head stage, we found that both bacterial community richness and evenness changed significantly. In …

Soybean disease research on green stem disorder, effects of seed treatments on Sclerotinia stem rot, and resistance to Cercospora leaf blight
Soybean plants often exhibit varying delayed maturity symptoms at the end of the growing season. One delayed maturity malady known as green stem disorder (GSD) is the occurrence of non-senescent, fleshy green stems at harvest maturity with normal, fully mature pods and seeds. Data on GSD incidence …
