A sensitive and specific detection method was developed for Xanthomonas hyacinthi; this method was based on amplification of a subsequence of the type IV fimbrial-subunit gene fimA from strain S148. The fimA gene was amplified by PCR with degenerate DNA primers designed by using the N-terminal and C-terminal amino acid sequences of trypsin fragments of FimA. The nucleotide sequence of fimA was ...

A total of 149 species and 209 strains of Korean Aphyllophorales in Seoul National University Fungus Collection (SFC) were analyzed by taxonomic and phylogenetic methods. Among those examined fungal specimens, 9 genera Abundisporus, Antrodiella, Cyphellopsis, Dendrothele, Dichomitus, Laxitextum, Piloderma, Skeletocutis and Tubulicrinis, and 23 species, Abundisporus fuscopurpureus, Antrodiella s...

Erbium(III) complexes of 2-hydroxy-l,4-naphthalenedione-1-oxime and its C-3 substituted derivatives are synthesized and characterized by elemental analysis, thermogravimetric analysis, infrared spectroscopy, magnetic susceptibility measurements 2-hydroxy-1,4-naphthalenedione-1-oxime derivatives are analysed using (1)H and (13)C NMR spectroscopy. The molecular composition of the synthesized comp...

A total DNA clone bank of a strain of Xanthomonas campestris pv. malvacearum (Xcm) was constructed in the cosmid vector pSa747 and transfected into Escherichia coli. The Xcm strain carries at least nine identifiable avirulence (A) genes. Clones in E. coli were mated individually into a recombination-proficient Xcm isolate carrying no known A genes. Screening was for incompatibility on congenic ...

An investigation of the MeOH extract from the roots of Peritassa campestris (Hippocrateaceae) afforded two isomeric seco-A-ring quinonemethide triterpenoids, campestrine-I (1) and -II (2). This appears to be the first report of a C26,-type triterpene carbon skeleton from the Celastraceae or Hippocrateaceae families. The structures were elucidated on the basis of spectral data, particularly HMQC...

Xanthan gum is exo-polysaccharide, produced by Xanthomonas campestris. Considering a reactor operating in continuous mode, optimum dilution rate is determined by maximization condition. Optimum dilution rate is the dilution rate at which the productivity of xanthan gum is maximum. The current work is focused on implementing an algorithm for design of reactor, having optimum dilution rate as the...

Two major approaches address the need to predict species distributions in response to environmental changes. Correlative models estimate parameters phenomenologically by relating current distributions to environmental conditions. By contrast, mechanistic models incorporate explicit relationships between environmental conditions and organismal performance, estimated independently of current dist...

The genome of Xanthomonas campestris pv. vesicatoria encodes a constitutively expressed small RNA, which we designate PtaRNA1, "Plasmid transferred anti-sense RNA". It exhibits all hallmarks of a novel RNA antitoxin that proliferates by frequent horizontal transfer. It shows an erratic phylogenetic distribution with occurrences on chromosomes in a few individual strains distributed across both ...
