Cyanobacteria are suitable for sustainable, solar-powered biotechnological applications. Synthetic biology connects biology with computational design and an engineering perspective, but requires efficient tools and information about the function of biological parts and systems. To enable the development of cyanobacterial Synthetic Biology, several molecular tools were developed and characterized: (i) a broad-host-range BioBrick shuttle vector, pPMQAK1, was constructed and confirmed to replicate in Escherichia coli and three different cyanobacterial strains. (ii) The fluorescent proteins Cerulean, GFPmut3B and EYFP have been demonstrated to work as reporter proteins in cyanobacteria, in spite of the strong background of photosynthetic pigments. (iii) Several promoters, like P(rnpB) and variants of P(rbcL), and a version of the promoter P(trc) with two operators for enhanced repression, were developed and characterized in Synechocystis sp. strain PCC6803. (iv) It was shown that a system for targeted protein degradation, which is needed to enable dynamic expression studies, is working in Synechocystis sp. strain PCC6803. The pPMQAK1 shuttle vector allows the use of the growing numbers of BioBrick parts in many prokaryotes, and the other tools herein implemented facilitate the development of new parts and systems in cyanobacteria.

In order to cover more commodity/country-combinations, the Nordic countries (Finland, Sweden, Norway and Denmark) are co-operating in monitoring. In 2008 the countries agreed to monitor samples from Africa. Together the Nordic countries analyzed a total of 623 samples from 18 different countries. Most of the samples came from South Africa (249), followed by Egypt (129), Morocco (92) and Kenya (88). In total 45 different commodities were analyzed, oranges (162) being the largest group, followed by beans with pods (80) and table grapes (71). In the analytical scope 220 to 345 pesticides and metabolites were covered
