... Plant surfaces are colonised by an array of microbes. These microbes have been implicated in protecting plants against invading pathogens. Studies have demonstrated that metabolites of phylloplane microfungi can induce defence responses in their host plants. This investigation relates to formulation of a biocide from metabolites of Aspergillus niger , Trichoderma viride , Alternaria alternata and ...

Abstract:
... Sharp eyespot caused by Rhizoctonia cerealis was assessed in four winter wheat crops surveyed at four locations in north-central Poland in 2006–2009. At the four locations symptoms developed on 41.9–67.7 % of shoots of all plants (average of 4 years) and on 49–73.5 % of shoots of diseased plants (average of 4 years). Slight (category 1) disease was most frequent, occurring on 24.4–41.3 % of shoots ...

Abstract:
... The oil rose, Rosa damascena Mill. (Rosaceae) is an agricultural crop cultivated in various countries of the northern hemisphere, such as Turkey, Bulgaria, Morocco, Iran, Egypt, France, China and India. Iran, presently, is the largest producer of rose water in world. The major production areas in Iran are Kashan, Fars, Kerman and Azerbaijan. Kerman province with 2297 hectares ha of rose gardens an ...

Abstract:
... Plant pathogenic fungi cause important yield losses in crops. A proteomic approach was used to study the changes in the leaf proteome profile of the plant Mentha arvensis infected with a necrotrophic fungus, Alternaria alternata. High-resolution two-dimensional gel electrophoresis (2-DE) followed by colloidal Coomassie staining and mass spectrometric analysis was used to identify highly abundant p ...

Abstract:
... Blueberries are traditionally consumed in North America, some European countries and Japan. In Argentina, the blueberry crop is profitable because production starts in November, when the northern hemisphere lacks fresh fruit. Fungal contaminants can grow and produce mycotoxins in fresh fruit. The aims of this work were to identify the main genera of the mycobiota of blueberries grown in Argentina ...

Abstract:
... Overexpression of antifungal pathogenesis-related (PR) proteins in crop plants has the potential for enhancing resistance against fungal pathogens. Thaumatin-like proteins (TLPs) are one group (PR-5, permatins) of antifungal PR-proteins isolated from various plants. In the present study, a plasmid containing a cDNA of rice tlp (D34) under the control of the CaMV-35S promoter was introduced into to ...

Abstract:
... Amaranthus retroflexus L. is a common annual weed worldwide. It can be found in a wide range of habitats and causes substantial yield reduction in many crops mainly through competition. Alternaria spp. are airborne molds that are considered to have potential for the biological control of weeds. The aim of this study was to assess the effect of spore concentration, host-plant growth stage, dew peri ...
