Verticillium wilt (caused by dahliae Kleb.) is an important disease affecting olive (Olea europaea L.) production. Effective control of this relies on integrated management strategies. In vitro antifungal activity two hydroxytyrosol (HTyr) enriched extracts (HTE1 and HTE2) obtained from mill waste products (OMWP) was assessed against V. dahliae. Inhibitory effects pure HTyr as a standard, HTE1 ...

Using PCR-based assays with specific primers for amplification of the ribosomal DNA intergenic spacer region (IGS) and a portion of the mitochondrial DNA small subunit ribosomal RNA gene (mtDNA SSU rRNA), the genetic variability among Verticillium dahliae isolates from olive (Olea europaea) and other host species from Argentina and Brazil was estimated. The derived UPGMA-generated phenograms ba...

Pathogenic Verticillium species are economically important plant pathogens that cause vascular wilt diseases in hundreds of plant species. The Ve1 gene of tomato confers resistance against race 1 strains of Verticillium dahliae and V. albo-atrum. Ve1 encodes an extracellular leucine-rich repeat (eLRR) receptor-like protein (RLP) that serves as a cell surface receptor for recognition of the rece...

Olive cultivation is affected by a wide range of biotic constraints. Verticillium wilt of olive is one of the most devastating diseases affecting this woody crop, inflicting major economic losses in many areas, particularly within the Mediterranean Basin. Little is known about gene-expression changes during plant infection by Verticillium dahliae of woody plants such as olive. A complete RNA-se...

To study the effect of plant species on the abundance and diversity of bacterial antagonists, the abundance, the phenotypic diversity, and the genotypic diversity of rhizobacteria isolated from potato, oilseed rape, and strawberry and from bulk soil which showed antagonistic activity towards the soilborne pathogen Verticillium dahliae Kleb. were analyzed. Rhizosphere and soil samples were taken...

Verticillium wilt, a disease caused by the fungus dahliae, affects vast range of crops, including strawberries. A field trial was established to evaluate effect broccoli in rotation prior strawberries, anaerobic soil disinfestation (ASD), and mustard cake (MC) alone combination at suppressing V. dahliae. Broccoli, cauliflower fallow plots were year 1, followed strawberry, winter cover crop, let...

Verticillium wilt is a vascular disease causing tremendous damage to cotton production worldwide. However, our knowledge of the mechanisms resistance or susceptibility this very limited. In study, we compared defense transcriptomes (Gossypium hirsutum) cultivars Shidalukang 1 (Verticillium dahliae resistant, HR) and Junmian (V. susceptible, HS) before after V. infection, identified hub genes ne...

Young, visually symptomless leaves from potato (Solanum tuberosum) plants infected with Verticillium dahliae exhibited reduced carbon assimilation rate, stomatal conductance, and intercellular CO(2), but no increase in dark respiration, no change in the relationship between carbon assimilation rate versus intercellular CO(2), and no change in light use efficiency when intercellular CO(2) was he...

Sustainable management of crop productivity and health necessitates improved understanding of the ways in which rhizosphere microbial populations interact with each other, with plant roots and their abiotic environment. In this study we examined the effects of different soils and cultivars, and the presence of a soil-borne fungal pathogen, Verticillium dahliae, on the fungal microbiome of the r...
