Molecular mechanism of regulation of siderophore-mediated iron assimilation.
This review describes a molecular mechanism for regulation of one pathway of microbial assimilation of iron, an element which may well be a nutrient required by all living cells. Unlike organic compounds, minerals cannot be synthesized and must be acquired from the environment. In contrast to amino acids, fatty acids, and monosaccharides, all of which can be accumulated in the form of relativel...
متن کاملSiderophore Biosynthesis But Not Reductive Iron Assimilation Is Essential for Aspergillus fumigatus Virulence
The ability to acquire iron in vivo is essential for most microbial pathogens. Here we show that Aspergillus fumigatus does not have specific mechanisms for the utilization of host iron sources. However, it does have functional siderophore-assisted iron mobilization and reductive iron assimilation systems, both of which are induced upon iron deprivation. Abrogation of reductive iron assimilatio...
متن کاملBiological Control of the Crown Gall Disease
A combination of the crown gall biocontrol strain K-84 and another antagonist JH-l was better than K-84 alone in controlling some Agrobacterium strains. Strain K-84 surprisingly controlled some resistant Agrobacterium strains when heavy concentrations of K-84 were used. Strain K-84 could control sensitive strains of Agrobacterium up to 48 hr. after wounds were inoculated with the pathogen at te...
متن کاملRNAi-mediated oncogene silencing confers resistance to crown gall tumorigenesis.
Crown gall disease, caused by the soil bacterium Agrobacterium tumefaciens, results in significant economic losses in perennial crops worldwide. A. tumefaciens is one of the few organisms with a well characterized horizontal gene transfer system, possessing a suite of oncogenes that, when integrated into the plant genome, orchestrate de novo auxin and cytokinin biosynthesis to generate tumors. ...
متن کاملIsolation of Agrobacterium Tumefaciens Strains from Crown Gall Disease on Imported Roses Plants in Qazvin Province
Cultivar of roses (Rosa spp.) has been grown in greenhouses in Qazvin region of Iran for local markets. Agrobacterium tumefaciens strains were isolated and identified from six different samples of roses plants imported from the Netherland to Iran. During August and September of 2012, nearly 2-5% of rose plants in two different greenhouses in the province of Qazvin were observed with crown gall ...
