Finding new sustainable tools for crop protection in horticulture has become mandatory. Giant reed (Arundo donax L.) is a tall, perennial, widely diffuse lignocellulosic grass, mainly proposed bioenergy production due to the fact of its high biomass yield and low agronomic requirements. Some studies have already highlighted antimicrobial antifungal properties giant reed-derived compounds. This ...

Many fungi are known to secrete lectins, but their functional roles are not clearly understood. Sclerotium rolfsii, a soilborne plant pathogenic fungus capable of forming fruiting bodies called sclerotial bodies, secrete a cell wall-associated Thomsen-Friedenreich antigen-specific lectin. To understand the functional role of this lectin, we examined its occurrence and expression during developm...

Weiland, J. E. 2014. Pythium species and isolate diversity influence inhibition by the biological control agent Streptomyces lydicus. Plant Dis. 98:653-659. Disease control of soilborne pathogens by biological control agents (BCAs) is often inconsistent under field conditions. This inconsistency may be partly influenced by pathogen diversity if there is a differential response among pathogen sp...

Both the establishment and outcomes of plant-fungus symbioses can be influenced by abiotic factors, the interplay of fungal and plant genotypes, and additional microbes associated with fungal mycelia. Recently bacterial endosymbionts were documented in soilborne Glomeromycota and Mucoromycotina and in at least one species each of mycorrhizal Basidiomycota and Ascomycota. Here we show for the fi...

UNLABELLED During a screening for potential plant disease control actinomycetes, a total of 133 strains were isolated from Saharan soil samples of seven Algerian regions by dilution technique on chitin-vitamins agar medium. Screening for antagonistic properties using streak assay method showed that 25% of isolates demonstrated strong activities against a wide range of plant pathogenic fungi. Du...

the experiment was done in a factorial design based on completely randomized with three factors and five replications in vitro. the first factors, plant extract (nine plant species), the second factor, solvent (5 solvent) and the third factor, concentration (3 concentration) were considered. in pot condition, the experiment was carried out in factorial based on completely randomized design with...

Verticillium dahliae is a cosmopolitan, soilborne fungus that causes a significant wilt disease on a wide variety of plant hosts including economically important crops, ornamentals, and timber species. Clonal expansion through asexual reproduction plays a vital role in recurring plant epidemics caused by this pathogen. The recent discovery of recombination between clonal lineages and preliminar...
