Abstract:
... Southern corn leaf blight (SCLB), caused by the fungus Bipolaris maydis, is a disease that significantly affects maize productivity across the globe. A detached leaf assay (DLA) was developed to rapidly assess maize resistance to SCLB. Several experiments were conducted to: (i) identify a highly virulent B. maydis isolate; and to determine the most appropriate (ii) phytohormone to maintain viabili ...

Abstract:
... Downy mildew, caused by the obligate oomycete Peronospora effusa (Pfs), is the most economically important disease of spinach. In recent years, numerous new races of the pathogen have overcome the resistance used in newly released cultivars. Resistance to Pfs in spinach is predominantly governed by dominant major resistance genes (RPFs) that are widely used in commercial spinach hybrid cultivars. ...
