Ralstonia solanacearum is a widespread and destructive plant pathogen. We present the genome of the type strain, K60 (phylotype IIA, sequevar 7). Sequevar 7 strains cause ongoing tomato bacterial wilt outbreaks in the southeastern United States. K60 generally resembles R. solanacearum CFBP2957, a Caribbean tomato isolate, but has almost 360 unique genes.

Community diversity and abundance of biofilms from a full-scale drinking water distribution system in Shanghai were characterized by denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA sequences and heterotrophic plate count (HPC), respectively. Bacteria affiliated to the Beta- and Gamma-Proteobacteria were dominating in both in-situ and HPC-culturable bacterial communities. Oth...

The effect of environmental pollutants on living organisms can be assessed by studying the changes in indigenous microbial community. Therefore, present study, cultivatable bacterial community non-polluted as well household sewage and industrially polluted water Lai Nullah flowing through Islamabad-Rawalpindi, Pakistan was analysed. Bacterial composition population significantly different from ...

spp. is a major pathogenic microbe for tomato, which Background: Ralstonia invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. Ralstonia spp. produces several virulence factors helping it to invade the plant’s natural defense mechanism. Native isolates of Trichoderma spp., Pseudomonas and can be used ...

Ralstonia solanacearum strain FQY_4 was isolated from a bacterial wilt nursery, which is used for breeding crops for Ralstonia resistance in China. Here, we report the complete genome sequence of FQY_4 and its comparison with other published R. solanacearum genomes, especially with the strains GMI1000 and Y45 in the same group.

Short-chain-length/medium-chain-length (SCL/MCL) polyhydroxyalkanoate (PHA) was produced in the plastids of Arabidopsis thaliana. Phe87Thr (F87T) mutated 3-ketoacyl-acyl carrier protein (ACP) synthase III (FabH) from Escherichia coli , and Ser325Thr/Gln481Lys (ST/QK) mutated polyhydroxyalkanoate (PHA) synthase (PhaC1) from Pseudomonas sp. 61-3, along with the beta-ketothiolase (PhaA) and acetoa...

The gene loci ehyAB, calA, and calB, encoding eugenol hydroxylase, coniferyl alcohol dehydrogenase, and coniferyl aldehyde dehydrogenase, respectively, which are involved in the first steps of eugenol catabolism in Pseudomonas sp. strain HR199, were amplified by PCR and combined to construct a catabolic gene cassette. This gene cassette was cloned in the newly designed broad-host-range vector p...

The genetic and phenotypic diversity of the Ralstonia solanacearum species complex, which causes bacterial wilt to Solanacae, was assessed in 140 strains sampled from the main vegetable production areas of the Mayotte island. Only phylotype I strains were identified in the five surveyed areas. The strains were distributed into the following 4 sequevars: I-31 (85.7%), I-18 (5.0%), I-15 (5.7%), a...
