Benefit from decline: the primary transcriptome of Alteromonas macleodii str. Te101 during Trichodesmium demise.

Interactions between co-existing microorganisms deeply affect the physiology of the involved organisms and, ultimately, the function of the ecosystem as a whole. Copiotrophic Alteromonas are marine gammaproteobacteria that thrive during the late stages of phytoplankton blooms in the marine environment and in laboratory co-cultures with cyanobacteria such as Trichodesmium. The response of this heterotroph to the sometimes rapid and transient changes in nutrient supply when the phototroph crashes is not well understood.

Finished Genome Sequence of the Unicellular Cyanobacterium Synechocystis sp. Strain PCC 6714.

Synechocystis sp. strain PCC 6714 is a unicellular cyanobacterium closely related to the popular model organism Synechocystis sp. strain PCC 6803.

A PCR-based assay to detect En/Spm-like transposon sequences in plants.

Degenerate primers deduced from the TPase region of plant En/Spm-like transposons allowed the amplification of similar sequences from various plant species including sugar beet, wheat and pea. These primers are efficient tools for the detection of this family of transposons in many plant genomes irrespective of sequence knowledge or phenotypic pecularities. An efficient PCR assay was therefore developed for these class II transposons, similar to assays already available for Ty1-copia-, Ty3-gypsy- or LINEs.
