The European Court of Justice's decision that gene editing should be regulated as genetic modification has wide implications for plant science and agriculture. However, the original EU legislation for environmental releases of GMOs already allows for more flexibility to regulate gene‐edited plants. [Image: see text]
Bioeconomy, biotechnology and genetically-modified organisms in particular have been the subject of discussion for a long time. Biotechnology is applied in a variety of economic areas which include biopharmaceuticals, biobased products and agriculture. During the last 20 years, innovative biotechnological techniques for plant genome improvement have been developed. Many factors worldwide have led to the status quo : different legislations around the world, the lack of public acceptance in the EU and high expectations for new strategies for sustainability and food security. Therefore, a clear regulatory status for new techniques is crucial for research and development, as well as for their practical implementation. This should be based on solid science which plays a critical role in developing the bioeconomy. ; This paper was partially supported by both the Polish Ministry of Science and Higher Education within the KNOW program and a grant for young scholars as well as the Polish Ministry of Agriculture and Rural Development within the multiannual program 2015-2020. ; Peer reviewed

The current challenge of agriculture is to ensure sustainability, noting that in the next half century we must produce as much food as in the previous ten thousand years combined. At the same time, we should improve crop resilience, in an unquestionable scenario of climate change. The World Food and Agriculture Organization (FAO) urges us to achieve food security, which is the situation in which everybody has physical and economic access to sufficient, safe nutritious food at all times, to satisfy their nutritional needs and preferences, in order to lead an active and healthy life. In recent years we have seen an exponential increase in the knowledge of the molecular basis of genetic traits that are important for food production. Some of these technologies have been developed in Europe, and benefit producers from other parts of the world, from whom our countries then import their products for our consumption. It has been possible to increase the micronutrient content of fruit, delay their ripening or incorporate resistance to viruses, fungi and bacteria. Thus, using tools borrowed from bacterial defence mechanisms (CRISPR-Cas9 and derivatives), it is possible to act in a controlled and timely manner on the desired areas of DNA (Deoxyribonucleic Acid), as could be the case in the fight against TR4 fungus in the banana. This crop occupies about ten million hectares with an annual production of one-hundred million tons. It is part of the basic diet of four-hundred million people and is cultivated in all tropical and subtropical regions constituting the fourth food crop only behind rice, wheat and corn. No fungicide has been found that allows chemical control of the fungus that remains in infected soils for periods exceeding thirty years, so it is urgent to obtain new resistant varieties. This document aims to sensitize society and legislators about the importance of science and technology, with a sustainable global food system approach (availability, policies, economy and culture) to meet the food challenges of the 21st century. ; Peer reviewed
Cinnamyl alcohol dehydrogenase (CAD) is a key enzyme involved in the last step of monolignol biosynthesis. The effect of CAD down-regulation on lignin production was investigated through a transgenic approach in maize. Transgenic CAD-RNAi plants show a different degree of enzymatic reduction depending on the analyzed tissue and show alterations in cell wall composition. Cell walls of CAD-RNAi stems contain a lignin polymer with a slight reduction in the S-to-G ratio without affecting the total lignin content. In addition, these cell walls accumulate higher levels of cellulose and arabinoxylans. In contrast, cell walls of CAD-RNAi midribs present a reduction in the total lignin content and of cell wall polysaccharides. In vitro degradability assays showed that, although to a different extent, the changes induced by the repression of CAD activity produced midribs and stems more degradable than wild-type plants. CAD-RNAi plants grown in the field presented a wild-type phenotype and produced higher amounts of dry biomass. Cellulosic bioethanol assays revealed that CAD-RNAi biomass produced higher levels of ethanol compared to wild-type, making CAD a good target to improve both the nutritional and energetic values of maize lignocellulosic biomass. ; This work was supported by the Spanish 'Ministerio de Ciencia e Innovación' (AGL2008–05157), the European Community ('COPOL' project: integrated control of polysaccharide and lignin biosynthesis to improve cellulose content and availability and fibre quality, QLK5-CT-2000–01493), and the CONSOLIDER-INGENIO program (CSD2007–00036).

We report an improved assembly (v3.6.1) of the melon (Cucumis melo L.) genome and a new genome annotation (v4.0). The optical mapping approach allowed correcting the order and the orientation of 21 previous scaffolds and permitted to correctly define the gap-size extension along the 12 pseudomolecules. A new comprehensive annotation was also built in order to update the previous annotation v3.5.1, released more than six years ago. Using an integrative annotation pipeline, based on exhaustive RNA-Seq collections and ad-hoc transposable element annotation, we identified 29,980 protein-coding loci. Compared to the previous version, the v4.0 annotation improved gene models in terms of completeness of gene structure, UTR regions definition, intron-exon junctions and reduction of fragmented genes. More than 8,000 new genes were identified, one third of them being well supported by RNA-Seq data. To make all the new resources easily exploitable and completely available for the scientific community, a redesigned Melonomics genomic platform was released at http://melonomics.net. The resources produced in this work considerably increase the reliability of the melon genome assembly and resolution of the gene models paving the way for further studies in melon and related species. ; This work was supported by the Spanish Ministry of Economy and Competitiveness grant AGL2015–64625-C2-1-R, Severo Ochoa Programme for Centres of Excellence in R&D 2016–2010 (SEV-2015–0533) and the CERCA Programme/Generalitat de Catalunya to JGM.

53 pages, 10 figures, 20 tables ; This paper provides an overview of the last 40 years of use, and in many cases abuse, of the natural resources in Catalonia, a country that is representative of European countries in general, and especially those in the Mediterranean region. It analyses the use of natural resources made by mining, agriculture, livestock, logging, fishing, nature tourism, and energy production and consumption. This use results in an ecological footprint, i.e., the productive land and sea surface required to generate the consumed resources and absorb the resulting waste, which is about seven times the amount available, a very high number but very similar to other European countries. This overexploitation of natural resources has a huge impact on land and its different forms of cover, air, and water. For the last 25 years, forests and urban areas have each gained almost 3% more of the territory at the expense of agricultural land; those municipalities bordering the sea have increased their number of inhabitants and activity, and although they only occupy 6.7% of the total surface area, they account for 43.3% of the population; air quality has stabilized since the turn of the century, and there has been some improvement in the state of aquatic ecosystems, but still only 36% are in good condition, while the remainder have suffered morphological changes and different forms of nonpoint source pollution; meanwhile the biodiversity of flora and fauna remains still under threat. Environmental policies do not go far enough so there is a need for revision of the legislation related to environmental impact and the protection of natural areas, flora, and fauna. The promotion of environmental research must be accompanied by environmental education to foster a society which is more knowledgeable, has more control and influence over the decisions that deeply affect it. Indeed, nature conservation goes hand in hand with other social and economic challenges that require a more sustainable vision. Today's problems with nature derive from the current economic model, which is environmentally unsustainable in that it does not take into account environmental impacts. Lastly, we propose a series of reasonable and feasible priority measures and actions related to each use made of the country's natural resources, to the impacts they have had, and to their management, in the hope that these can contribute to improving the conservation and management of the environment and biodiversity and move towards sustainability ; This research was funded by the Institut d'Estudis Catalans (IEC).
