Abstract:
... Fungal plant diseases driven by weather factors are common in European wheat and barley crops. Among these, septoria tritici blotch (Zymoseptoria tritici), tan spot (Pyrenophora tritici-repentis), and stagonospora nodorum blotch (Parastagonospora nodorum) are common in the Nordic-Baltic region at variable incidence and severity both in spring and winter wheat fields. In spring barley, net blotch ( ...

The necrotrophic fungus Botrytis cinerea, the causal agent of grey mould, affects crops pre- and post-harvest and cause huge economical losses. Microorganisms and microbially-derived elicitors are known to induce plant defences. Here, we study ...

Because the origin and diversity of this pathogen are unknown, it is difficult to predict its behavior and invasive capacity, especially under future climate-change scenarios. We characterized genetic relationships and ecological differences ...

Abstract:
... Vascular wilt caused by the soil-borne fungus Verticillium dahliae is a major yield and quality-limiting disease across a broad spectrum of crop plants worldwide. Sulphur-enhanced plant defence mechanisms provide an opportunity to effectively and environmentally safely constrain the wilt disease levels in planta. To evaluate the influence of sulphur nutrition on the protective potential of these m ...

Abstract:
... Verticillium dahliae Kleb. causes Verticillium wilts in many herbaceous and woody species. Many hosts of the pathogen are commonly cultivated in Andalucía (southern Spain), particularly major crops such as cotton, vegetables, almond, peach and, particularly, olive, in which the fungus causes Verticillium wilt of olive. Infective structures of the pathogen (microsclerotia), produced in the late pha ...

Abstract:
... The tendentious decrease in global arable land and the fast increment in world population will inevitably lead to a critical point. It is therefore imperative to protect crops from pathogen attack. Their deleterious impact on human health is not better, with several invasive infections reaching mortality rates up to 80%. The door is definitely open for biological control, based on molecular intera ...

The S strain morphotype of Aspergillus flavus was identified as the primary cause of aflatoxin contamination events occurring between 2004 and 2006 in Kenya. Because the S strain was first described in the U.S., it was suggested that the ...

Onion downy mildew (Dm) symptoms and damage on seed production fields in southern Uruguay were quantified during two seasons as the progress of incidence, severity, and as the effect of the level of seed-stalks infections on seed yield and quality. In addition, the effects of two plantation dates and two plant densities on Dm were studied in a factorial experiment. Maximum incidence along the seas ...

As the disease progressed, lesions expanded and merged, resulting in withering of leaf tips. A ...

Commercial cultivation of tomato is hampered by the lack of resistance. Quantitative resistance has been reported in wild tomato relatives, mostly based on leaf assays. We aimed to identify wild tomato relatives with resistance to B. cinerea based on quantitative assa ...
