Clavibacter michiganensis subsp. sepedonicusis is a Gram-positive actinomycete that is the causative agent of the potato disease ring rot. Here, we announce the complete genome sequence of the Clavibacter michiganensis subsp. sepedonicusis siphophage CN1A. CN1A is only the second fully sequenced Clavibacter michiganensis subsp. sepedonicusis phage reported to date. Core and unique features of i...

In 2014, the pathogen Clavibacter michiganensis subsp. nebraskensis was isolated from symptomatic corn leaves in Manitoba, Canada. We report the draft genome sequence of C. michiganensis subsp. nebraskensis DOAB 397, consisting of 3.059 Mb with 73.0% G+C content, 2,922 predicted protein-coding sequences, 45 tRNAs, 3 rRNAs, and 37 pseudogenes.

Pseudomonas brassicacearum LBUM300, a plant rhizosphere-inhabiting bacterium, produces 2,4-diacetylphloroglucinol and hydrogen cyanide and has shown antagonistic activity against the plant pathogens Verticillium dahliae, Phytophthora cactorum, and Clavibacter michiganensis subsp. michiganensis. Here, we report the complete genome sequence of P. brassicacearum LBUM300.

The Gram-positive genus Clavibacter harbors economically important plant pathogens infecting a variety of agricultural crops, such as potato, tomato, corn, barley, etc. Here, we report five new genome sequences, those of strains CFIA-Cs3N, CFIA-CsR14, LMG 3663T, LMG 7333T, and ATCC 33566T, from different subspecies of Clavibacter michiganensis All these genomic data will be used for reclassific...

Members of the actinomycete genus Clavibacter are known to produce antimicrobial compounds, but so far none of these compounds has been purified and characterized. We have isolated an antimicrobial peptide, michiganin A, from the tomato pathogen Clavibacter michiganensis subsp. michiganensis, using ammonium sulfate precipitation followed by cation-exchange and reversed-phase chromatography step...

Two bioactive cyclic dipeptides, cyclo(L-Pro-L-Tyr) and cyclo(D-Pro-L-Tyr), were isolated from the culture broth of Streptomyces sp. strain 22-4 and tested against three economically important plant pathogens, Xanthomonas axonopodis pv. citri, Ralstonia solanacearum and Clavibacter michiganensis. Both cyclic dipeptides were active against X. axonopodis pv. citri and R. Solanacearum with MIC of ...

Endophytic bacteria were isolated from the stalks of sugarcane, Saccharum officinarum, growing in Papua New Guinea. Endophytic bacterial communities from extracted juice averaged 6x 10 cfu/ml, which is 25 times greater than the number of endophytic bacteria found in commercial varieties in South Africa. Sixty isolates, representing the different colony morphology types, were used for in vitro i...

In this paper we describe transformation of Clavibacter michiganensis subsp. sepedonicus, the potato ring rot bacterium, with plasmid vectors. Three of the plasmids used, pDM100, pDM302, and pDM306, contain the origin of replication from pCM1, a native plasmid of C. michiganensis subsp. michiganensis. We constructed two new cloning vectors, pHN205 and pHN216, by using the origin of replication ...

The Gram-positive bacterium Clavibacter michiganensis subsp. michiganensis, causal agent of bacterial wilt and canker of tomato, is an economically devastating pathogen that inflicts considerable damage throughout all major tomato-producing regions. Annual outbreaks continue to occur in New York, where C. michiganensis subsp. michiganensis spreads via infected transplants, trellising stakes, to...

We report here the complete genome sequence of Clavibacter michiganensis subsp. insidiosus R1-1, isolated in Minnesota, USA. The R1-1 genome, generated by a de novo assembly of PacBio sequencing data, is the first complete genome sequence available for this subspecies.
