Phylogenetic relationships among picocyanobacteria from the Syn/Pro clade sensu Sánchez-Baracaldo et al. (2005) were determined using small subunit (ssu) rDNA sequences from novel culture isolates together with environmental samples from the Baltic

We have developed a technique for determining the genetic structure of populations of filamentous cyanobacteria. The sequence diversity at specific gene loci is first characterised in a range of clonal cultures; subsequent analysis involves individua

Aphanizomenon Morren is an important member of the cyanobacterial community in the Baltic Sea, but studies of this genus have been hampered by the difficulty of growing it in laboratory culture. PCR amplification of DNA from colonies picked directly

Part of the gas vesicle gene cluster was amplified by PCR from three strains of Planktothrix rubescens isolated from Lake Zürich, Switzerland. Each contains multiple alternating copies of gvpA and gvpC. All of the gvpA sequences in the different str

In 1993 isolates of Rhizobium leguminosarum bv. viciae were obtained from nodules formed by plants inoculated with soil samples from a variety of field sites in East Anglia (U.K.) and grouped into phenotypes (arbitrarily referred to as “strains”)

Rhizobium leguminosarum bv. viciae was isolated over 3 y from legumes nodulated with dilutions of soils from arable fields and uncultivated roadside verge sites, and from nodules of resident host legumes when present at these sites. Isolates were cha

Wild-type strains of the cyanobacterium Planktothrix rubescens have a cluster of gas vesicle ( gvp ) genes with repeats of alternating gvpA and gvpC . The gvpC occurs in three length variants, all with the same 3′-sequence, Ω C . Spontaneous non-b

Some cyanobacteria have been shown to exchange genetic information under laboratory conditions, but it has not been clear whether such genetic exchange occurs in the natural environment. To address this, a population genetic study was carried out on

The effect of relative humidity (RH) on the airborne survival of a Pseudomonas fluorescens strain was studied at 20, 40, 60 and 80% RH indoors. The aero-stable spore of Bacillus subtilis subsp. niger, used as a tracer of physical losses was compared
