Tartrate utilization genes promote growth of Agrobacterium spp. on grapevine


, : Tartrate utilization genes promote growth of Agrobacterium spp. on grapevine. Molecular Plant Microbe Interactions 11(8): 836-838

Crown gall on grapevine is mainly caused by Agrobacterium vitis, which metabolizes tartrate. Competition experiments between a tartrate-utilizing strain and its nonutilizing derivative showed that tartrate utilization confers a selective advantage on grapevine.

Agrobacterium vitis is a common pathogen of grapevine. Most strains utilize tartrate, an abundant compound in grapevine. Strain AB3 carries two tartrate utilization (or TAR) regions: TAR-I (on the large pTrAB3 plasmid) and TAR-II (on the AB3 Ti pl...

The nonvirulent, antagonistic Agrobacterium vitis strain F2/5 was tested for the presence of tartrate utilization plasmid(s) which commonly occur in virulent A. vitis isolates. Following transformation of F2/5 plasmid DNA into Agrobacterium tumefa...

The grapevine is the natural host of the tumorigenic bacterium Agrobacterium vitis. Most of the A. vitis isolates can use tartrate, an unusually abundant compound in grapevine. The nopaline strain, AB4, contains a 170-kb conjugative plasmid (pTrAB...
