Homoserine lactones: Do plants really listen to bacterial talk?
The bacterial quorum sensing signals N-acyl-L-homoserine lactones (AHL) enable bacterial cells to regulate gene expression depending on population density, which eventually leads to invasion of hosts. Only little is known about the molecular ways of plants reacting to these bacterial signals. Recently, we showed that the contact of Arabidopsis thaliana roots with N-hexanoyl-DL-homoserine-lactone (HHL) resulted in distinct transcriptional changes in roots and shoots, respectively. In addition, we provided evidence that Arabidopsis takes up bacterial AHLs, which are obviously transported throughout the plant. In sum, the bacterial quorum sensing signal AHL seems to influence plant growth, and may contribute to reprogram plants encountering bacterial pathogens or rhizosphere bacteria. However, as pointed out here, the response of plants to bacterial AHLs may depend on plant species and chemical structure of AHLs.

In silico search for nitric oxide sensitive promoter elements in Arabidopsis thaliana
A major challenge in biology is unravelling the mechanisms that regulate gene expression and an important task in this challenge is to identify binding sites for transcription factors in gene promoter regions. These binding sites are short DNA segments that are called motifs. Recent advances in genome sequence availability and in high-throughput gene expression analysis technologies have allowed for the development of computational methods for motif finding. The aim of our study was to identify NO-responsive elements in the promoter region of NO-regulated genes, based on microarray analyses. Using Genomatix Gene2Promotor and MatInspector, we identified eight families of TFBS occurred at least 15% more often in the promoter regions of the responsive genes in comparison to the promoter regions of 28447 Arabidopsis control genes. Most of these TFBSs, such as ocs element-like sequences and WRKY, were already reported to be involved in particular stresses response.
