“…The three that show the greatest amount of similarity are TtuBp, a tartrate transporter from Agrobacterium vitis (Salomone et al, 1996), Pht1p, a phthalate transporter from Pseudomonas putida (Nomura et al, 1992), and Dal5p, the allantoate transporter from S. cerevisiae (Rai et al, 1988) (Figure 6). The substrates of these transporters, and of other transporters with less similarity to Liz1p, all are small acidic metabolites with one or more carboxylic acid groups.…”

Liz1p, a Novel Fission Yeast Membrane Protein, Is Required for Normal Cell Division When Ribonucleotide Reductase Is Inhibited

Ribonucleotide reductase activity is required for generating deoxyribonucleotides for DNA replication. Schizosaccharomyces pombe cells lacking ribonucleotide reductase activity arrest during S phase of the cell cycle. In a screen for hydroxyurea-sensitive mutants in S. pombe, we have identified a gene, liz1 ϩ , which when mutated reveals an additional, previously undescribed role for ribonucleotide reductase activity during mitosis. Inactivation of ribonucleotide reductase, by either hydroxyurea or a cdc22-M45 mutation, causes liz1 Ϫ cells in G2 to undergo an aberrant mitosis, resulting in chromosome missegregation and late mitotic arrest. liz1 ϩ encodes a 514-amino acid protein with strong similarity to a family of transmembrane transporters, and localizes to the plasma membrane of the cell. These results reveal an unexpected G2/M function of ribonucleotide reductase and establish that defects in a transmembrane protein can affect cell cycle progression.

“…Ten tumorigenic isolates identified as R. radiobacter (Ti) also utilized L-tartaric acid ( Table 2). Tartrate utilization genes are located on the tartrate utilization plasmid (pTr) and pTi, which some strains of R. vitis (Ti) possess (Salomone et al 1996;Szegedi et al 1992). Thus, our result suggests that the isolates might have received the plasmids from R. vitis (Ti) strains.…”

“…L-Tartrate utilization by R. vitis is thought to play a role in host specificity (Szegedi 1985). On the other hand, R. radiobacter (Ti) isolated from host plants other than grapevine do not utilize L-tartaric acid, but some strains of R. radiobacter (Ti) isolated from grapevine do (Burr and Katz 1983;Salomone et al 1996Salomone et al , 1998Sawada and Tsuchiya 2003). Ten tumorigenic isolates identified as R. radiobacter (Ti) also utilized L-tartaric acid ( Table 2).…”

Grapevine crown gall caused by Rhizobium radiobacter (Ti) in Japan

In 2005, characteristic symptoms of crown gall on grapevines (Vitis vinifera L. cv. Muscat of Alexandria, and cv. Seto Giants) were observed in a commercial greenhouse-orchard in Okayama Prefecture, Japan. Isolations from diseased tissues consistently yielded bacterial colonies that were white, glistening, and produced abundant polysaccharide on potato semi-synthetic agar (PSA) medium. Ten representative isolates were chosen for further characterization. A multiplex polymerase chain reaction (PCR) assay showed these strains were not Rhizobium vitis but did possess a Ti plasmid. The bacteriological characteristics of the isolates corresponded well with R. radiobacter. The almost complete 16S ribosomal DNA sequences of isolates AT06-1 and AT06-2, selected from 10 grapevine isolates, were determined and corresponded to sequences of R. radiobacter. The pathogenicity of the isolates was tested on young grapevine and tomato (Lycopersicon esculentum Mill.) plants. Gall symptoms developed on both plant species after inoculation, and bacteria with the same colony morphology as those inoculated were reisolated. Based on these results, the isolates were identified as R. radiobacter (Ti). This report is the first of the occurrence of R. radiobacter (Ti) on grapevine in Japan. Phylogenetic analyses using the partial nucleotide sequences of virC operon located on a Ti plasmid showed that the isolate of R. radiobacter (Ti) isolated from grapevine and some strains of R. vitis (Ti) belonged to the same monophyletic group, which differed from the groups of R. radiobacter (Ti) isolated from plants other than grapevine and of the majority of R. vitis (Ti) strains isolated from grapevine.

“…The tar region consists of the ttuA-E genes, orfX, orfY and a second ttuC copy. AB4 carries another tar region variant on pTrAB4, TAR-III (Salomone et al, 1996). The tar regions are thus found in different plasmid contexts and are also present in other bacteria, like Pseudomonas putida (Tipton and Beecher, 1994).…”
