The diversity of a distributed genome in bacterial populations (2009)
Baumdicker, F., Hess, W. R., Pfaffelhuber, P.
The distributed genome hypothesis states that the set of genes in a population of bacteria is distributed over all individuals that belong to the specific taxon. It implies that certain genes can be...
Lower Hybrid Current Drive in Tore Supra and Jet (1991)
Moreau, D., Gormezano, C., Agarici, G., Agostini, E., Ane, J. M., Auge, N., ...
Recent Lower Hybrid Current Drive (LHCD) experiments in TORE SUPRA and JET are reported. Large multijunction launchers have allowed the coupling of 5 MW to the plasma for several seconds with a...
Coexistence of phycoerythrin and a chlorophyll a/b antenna in a marine prokaryote.
Hess, W R, Partensky, F, Van Der Staay, G W, Garcia-Fernandez, J M, Börner, T, Vaulot, D
Prochlorococcus marinus CCMP 1375, a ubiquitous and ecologically important marine prochlorophyte, was bound to possess functional genes coding for the alpha and beta subunits of a phycobiliprotein....
Holtzendorff, J., Partensky, F., Jacquet, S., Bruyant, F., Marie, D., Garczarek, L., ...
The cell cycle of the chlorophyll b-possessing marine cyanobacterium Prochlorococcus is highly synchronized under natural conditions. To understand the underlying molecular mechanisms we cloned and...
Prochlorococcus, a Marine Photosynthetic Prokaryote of Global Significance
Partensky, F., Hess, W. R., Vaulot, D.
The minute photosynthetic prokaryote Prochlorococcus, which was discovered about 10 years ago, has proven exceptional from several standpoints. Its tiny size (0.5 to 0.7 μm in diameter) makes it the...
Precise branch point mapping and quantification of splicing intermediates.
Vogel, J, Hess, W R, Börner, T
Lariat intermediates of a group II intron were investigated via RT-PCR. Several reverse transcriptases appeared capable of reading through a branched nucleotide. A new method has been established...
Vogel, J, Börner, T, Hess, W R
The barley mutant albostrians and the maize mutants crs1 and crs2 are defective in the splicing of various plastid group II introns. By analysing tRNA precursors and several mRNAs not previously...
Inefficient rpl2 splicing in barley mutants with ribosome-deficient plastids.
Hess, W R, Hoch, B, Zeltz, P, Hübschmann, T, Kössel, H, Börner, T
Analysis of transcript accumulation and splicing in plastids of four nuclear mutants of barley revealed that the ribosomal protein L2 (rpl2) gene transcripts containing a group II intron remained...
Residual viruses in pork products.
McKercher, P D, Hess, W R, Hamdy, F
Partly cooked canned hams and dried pepperoni and salami sausages were prepared from the carcasses of pigs infected with African swine fever virus and pigs infected with hog cholera virus. Virus was...
Pan, I C, Huang, T S, Hess, W R
An indirect immunoperoxidase plaque-staining method was developed for detecting antibody to African swine fever virus infection. In both sensitivity and specificity, the test was comparable to...
Effects of Some Disinfectants on African Swine Fever Virus
Ten commercially available disinfectants were tested at high pH in 2% sodium hydroxide and low pH in 2% acetic acid as inactivants for African swine fever (ASF) in a protein-rich blood-spleen...
Hess, W R, Prombona, A, Fieder, B, Subramanian, A R, Börner, T
Transcription of plastid genes and transcript accumulation were investigated in white leaves of the albostrians mutant of barley (Hordeum vulgare) and in heat-bleached leaves of rye (Secale cereale)...
Zeltz, P, Hess, W R, Neckermann, K, Börner, T, Kössel, H
Sequence analysis of amplified cDNAs derived from the maize chloroplast rpoB transcript which encodes the beta subunit of a chloroplast specific, DNA dependent RNA polymerase reveals four C-to-U...
A Plaque Assay for Duck Plague Virus
A plaque assay for duck plague virus was developed for a chicken embryo-adapted virus and a duck lethal virus and used to determine the identity of these viruses. Using the plaque inhibition...
African Swine Fever: Application of Immunoelectroosmophoresis for the Detection of Antibody
Pan, I. C., Boer, C. J. De, Hess, W. R.
Thirty-three pigs in three groups of nineteen, ten, and four pigs were infected with three different African swine fever (ASF) virus isolates, respectively. All virus isolates were attenuated to...
Immunofluorescence Plaque Assay for African Swine Fever Virus
Tessler, J., Hess, W. R., Pan, I. C., Trautman, R.
Suitably diluted cell culture adapted African swine fever virus preparations were inoculated on VERO cell monolayers and grown on coverslips. Gum tragacanth was used as an overlay. After three days...
Complete 5' and 3' end maturation of group II intron-containing tRNA precursors.
Higher plant chloroplasts provide the only experimentally validated example of functional tRNA genes that are disrupted by group II introns. Here, precursor transcripts for tRNA(Gly)(UCC),...
