Genes that are differentially expressed by resistant sugarcane varieties in response to challenge by pathogens or pests have the potential to be useful in Marker Assisted Selection (MAS) once a link with resistance has been confirmed. Methodologies and resources designed to maximise the discovery of genetic markers and to facilitate the isolation of full-length coding sequences of resistance ge...

Host ecological traits may limit exposure to infectious disease, thereby generating the wide variation in disease incidence observed between host populations or species. The exclusion of disease by ecological traits may then allow selection to act against physiological defenses when they are costly to maintain in the absence of disease. This study investigates ecological resistance in the Silen...

Once a pathogen, always a pathogen? Not so—the fungus Pseudozyma flocculosa provides an intriguing example of a pathogen that took a different route (reviewed in Bélanger et al., 2012). Initially isolated from a powdery-mildew–infected leaf, P. flocculosa acts as a strong antagonist of powdery mildews (Erysiphales) and was thus developed as a biocontrol agent. However, the mechanism by which it...

The corn smut fungus, Ustilago maydis, is a global pathogen responsible for extensive agricultural losses. Control of corn smut using traditional breeding has met with limited success because natural resistance to U. maydis is organ specific and involves numerous maize genes. Here, we present a transgenic approach by constitutively expressing the Totivirus antifungal protein KP4, in maize. Tran...

ABSTRACT Genetic resistance is the most efficient tool in crop disease management. Peanut smut currently one of important peanut diseases, with its incidence increasing terms both damage level and area covered. The aim this study was to assess response different genotypes obtained by Facultad de Agronomía y Veterinaria Universidad Nacional Río Cuarto (Argentina) their yield. During 2016/17, 201...
