Genes phytopathogenicity

As a first step in the study of the pectinolytic activity of AzospihUvm irakense (non-phytopathogen), we isolated and partially characterised A. irakeme genes that confer pectinolytic activity to Escherichia coU and Azospirillurn hrasilense... 

Fom- title compounds, 5-deoxy KDG Me estw, 5-epi KDG Me ester, 4-0-Me KDG Me ester and 4-deoxy KDG Me ester were prepared either from D-glucono-l,5-lactone or from 1,2 5,6 di-O-isopropylidene-D-mannitol. Biological tests perfcHined rat these molecules have shown that the compounds modified on the C-5 position (5-deoxy KDG Me ester and 5-epi KDG Me ester) are gratuitous inducers of the e>q>ression of pectinase genes in the phytopathogenic bacteria Erwinia Chrysanthemi when the C-4 modified molecules (4-0-Me KDG Me ester and 4-deoxy KDG Me ester) are not inducers.

Other putative CKX genes and gene fragments have been found in gene databases of phytopathogenic bacteria, such as Streptomyces spp. [99] causing potato scab, Legionella pneumophila and cyanobacterium Anahaena variabilis (Frebortova, unpublished).
