Magnaporthiopsis maydis reduces growth in maize plantlets without affecting root resistance to water flow

Leire Molinero‐Ruiz, Ana B. García-Carneros, Luca Testi

Late wilt is a disease caused by the soil-borne fungus Magnaporthiopsis maydis that severely limits the production of maize in countries with warm to hot climates. A particular characteristic of this disease is that, although the pathogen penetrates the roots in the …

Updated Characterization of Races of Plasmopara halstedii and Entomopathogenic Fungi as Endophytes of Sunflower Plants in Axenic Culture

Pedro Miranda‐Fuentes, Ana B. García-Carneros, Leire Molinero‐Ruiz

The management of downy mildew (Plasmopara halstedii) in sunflower, is heavily dependent on genetic resistance, whilst entomopathogenic fungi (EF) can reduce other sunflower diseases. In this work, we characterized P. halstedii from Spain and other countries collected in the past few years. …
