Zinc and iron are two essential micronutrients for plants. The homeostasis networks of the two metals are intertwined. Arabidopsis halleri is a zinc- and cadmium-tolerant and zinc-hyperaccumulating species, which also present adaptation of its iron homeostasis(1,4). Transcriptomic studies identified genes which are constitu-tively over-expressed in Arabidopsis halleri compared to Arabidopsis thaliana and which may have a role in metal tolerance or accumulation(2-4). Among them, a candidate gene encodes the FRD3 (FERRIC REDUCTASE DEFECTIVE 3) protein, a member of the MATE family of membrane transporters. FRD3 is a citrate transporter involved in iron homeostasis(5-7) and plays a role in zinc tolerance in A. thaliana(8). The FRD3 gene displays a complex regulation. In A. thaliana, alternative transcript initiation for FRD3 determines two transcripts, which dif-fer in their 5'UTRs and have differential translation efficiency. The two transcripts are selectively regulated under stress conditions: iron and zinc depletion, zinc excess or cadmium presence(9). In A. halleri, a single highly ex-pressed FRD3 transcript with high translation efficiency is present(9). [less ▲]

In the era that huge numbers of microbial genomes are being released in the databases, it becomes increasingly important to rapidly mine genes as well as predict the regulatory networks that control their expression. To this end, we have developed an improved and online version of the PREDetector software aimed at identifying putative transcription factor-binding sites (TFBS) in bacterial genomes. The original philosophy of PREDetector 1.0 is maintained, i.e. to allow users to freely fix the DNA-motif screening parameters, and to provide a statistical means to estimate the reliability of the prediction output. This new version offers an interactive table as well as graphics to dynamically alter the main screening parameters with automatic update of the list of identified putative TFBS. PREDetector 2.0 also has the following additional options: (i) access to genome sequences from different databases, (ii) access to weight matrices from public repositories, (iii) visualization of the predicted hits in their genomic context, (iv) grouping of hits identified in the same upstream region, (v) possibility to store the performed jobs, and (vi) automated export of the results in various formats. PREDetector 2.0 is available at http://predetector.fsc.ulg.ac.be/. [less ▲]

In A. halleri, a single highly ex-pressed FRD3 transcript with high translation efficiency is present(9). We are further examining the FRD3 function in zinc and iron homeostasis in A. thaliana and A. halleri. We will present data (i) on the high expression of FRD3 in A. halleri, (ii) on the functional characterization of the two alternative FRD3 transcripts and their role in metal homeostasis in A. thaliana in comparison with the A. halleri FRD3 transcript and (iii) on the zinc phenotypes of the frd3 A. thaliana mutant.
