Theoretical Prediction and Experimental Verification of Protein-Coding Genes in Plant Pathogen Genome Agrobacterium tumefaciens Strain C58

Agrobacterium tumefaciens strain C58 is a Gram-negative soil bacterium capable of inducing tumors (crown galls) on many dicotyledonous plants. The genome of A. tumefaciens strain C58 was re-annotated based on the Z-curve method. First, all the 'hypothetical genes' were re-identified, and 29 originally annotated 'hypothetical genes' were recognized to be non-coding open reading frames (ORFs). Th...

Attachment of Agrobacterium tumefaciens to carrot cells and Arabidopsis wound sites is correlated with the presence of a cell-associated, acidic polysaccharide.

An early step in crown gall tumor formation involves the attachment of Agrobacterium tumefaciens to host plant cells. A. tumefaciens C58::A205 (C58 attR) is a Tn3HoHo1 insertion mutant that was found to be avirulent on Bryophyllum daigremontiana and unable to attach to carrot suspension cells. The mutation mapped to an open reading frame encoding a putative protein of 247 amino acids which has ...

Isolation 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 ...

Phosphorus limitation enhances biofilm formation of the plant pathogen Agrobacterium tumefaciens through the PhoR-PhoB regulatory system.

The plant pathogen Agrobacterium tumefaciens forms architecturally complex biofilms on inert surfaces. Adherence of A. tumefaciens C58 was significantly enhanced under phosphate limitation compared to phosphate-replete conditions, despite slower overall growth under low-phosphate conditions. Replacement of Pi with sn-glycerol-3-phosphate and 2-aminoethylphosphonate yielded similar results. The ...
