Verticillium wilt resulting from infection by dahliae is one of the most devastating soilborne fungi olive tree (Olea europaea L.) worldwide. The pathogen infects a wide variety plants and can survive in soil for many years, chemicals cannot control it. Therefore, sustainable disease management strategies are suggested, with exploitation host resistance as predominant measure practice. In addit...

The soil nourishing the crops that provide our food and fiber is a complex environment where microbes live in numbers estimated to reach 2 billion per ounce of soil. Millions upon millions of individual bacteria and fungi Uve on root surfaces and the soil particles that surround them. Bacteria are the smallest and the most abundant. The fungi, usually larger than bacteria, are found throughout ...

Worldwide, Mediterranean-climate type forests are seriously threatened by climate change and Phytophthora cinnamomi, an extremely aggressive soilborne pathogen listed among the 100 worst invasive alien species. This study examines for first time effects of annual seasonal changes in temperature rainfall under different climatic scenarios on P. cinnamomi dynamics a Mediterranean forest naturally...

Rice sheath blight (ShB), caused by the soilborne pathogen Rhizoctonia solani, annually causes severe losses in yield and quality in many rice production areas worldwide. Jasmine 85 is an indica cultivar that has proven to have a high level of resistance to this pathogen. The objective of this study was to determine the ability of controlled environment inoculation assays to detect ShB resistan...

Ralstonia solanacearum, a soilborne plant pathogen of considerable economic importance, invades host plant roots from the soil. Qualitative and quantitative chemotaxis assays revealed that this bacterium is specifically attracted to diverse amino acids and organic acids, and especially to root exudates from the host plant tomato. Exudates from rice, a nonhost plant, were less attractive. Eight ...

The presence of Escherichia coli in water is used as an indicator of fecal contamination, but recent reports indicate that soil populations can also be detected in tropical, subtropical, and some temperate environments. In this study, we report that viable E. coli populations were repeatedly isolated from northern temperate soils in three Lake Superior watersheds from October 2003 to October 20...

In the Mediterranean area, tomato soilborne pathogens used to be controlled by methyl bromide, particularly in protected cultivation. To decrease the use of this fumigant, non-chemical and chemical alternatives were developed and implemented in many Mediterranean countries. However, the success of the alternative depends on the degree of its integration in an integrated pest management programme.

In this study, we present the draft genome sequence of the bacterial strain Pseudomonas chlororaphis PCL1601. This bacterium was isolated from the rhizosphere of healthy avocado trees and displayed antagonistic and biological control activities against different soilborne phytopathogenic fungi and oomycetes.
