    Abstract Several papers in a Special Issue of Sustainability have recently discussed various aspects to evaluate whether organic farming and gene manipulation are compatible. A special emphasis was given to new plant breeding techniques (NPBTs). These new approaches allow the most predictable genetic alterations of crop plants in ways that the genetically modified plant is identical to a plant generated by conventional breeding. The articles of the Special Issue present the arguments pro and contra the inclusion of the plants generated by NPBTs in organic farming. Organic movements have not yet made a final decision whether some of these techniques should be accepted or banned. In my view these novel genetically manipulated (GM) crops could be used in such a way as to respect the requirements for genetically manipulated organisms (GMOs) formulated by the International Federation of Organic Movements (IFOAM). Reviewing the potential benefits of disease-resistant potatoes and bananas, it seems possible that these crops support organic farming. To this end, I propose specific requirements that the organic movements should proactively formulate as their standards to accept specific GM crops.

    Abstract Convincing evidence has accumulated that unintended transgene escape occurs in oilseed rape, maize, cotton and creeping bentgrass. The escaped transgenes are found in variant cultivars, in wild type plants as well as in hybrids of sexually compatible species. The fact that in some cases stacked events are present that have not been planted commercially, implies unintended recombination of transgenic traits. As the consequences of this continuous transgene escape for the ecosystem cannot be reliably predicted, I propose to use more sophisticated approaches of gene technology in future. If possible GM plants should be constructed using either site-directed mutagenesis or cisgenic strategies to avoid the problem of transgene escape. In cases where a transgenic trait is needed, efficient containment should be the standard approach. Various strategies available or in development are discussed. Such a cautious approach in developing novel types of GM crops will enhance the sustainable potential of GM crops and thus increase the public trust in green gene technology.

    Abstract Based on recent advances in plant gene technology, I propose to develop a new category of GM plants, orgenic plants, that are compatible with organic farming. These orgenic plants do not contain herbicide resistance genes to avoid herbicide application in agriculture. Furthermore, they either contain genes that are naturally exchanged between species, or are sterile to avoid outcrossing if they received a transgene from a different species. These GM plants are likely to be acceptable to most skeptics of GM plants and facilitate the use of innovative new crops.

    Abstract The development of the first form of kidney, the pronephros, in the frog Xenopus is most attractive to study nephrogenesis in vertebrates. The formation of the pronephros can be readily analyzed during organogenesis by manipulating the activity of specific factors in the developing Xenopus embryo. In addition embryonic explants of Xenopus can be induced to pronephric differentiation in vitro by adding defined signaling molecules. The available data show that the same transcription factors and signaling molecules play a role in Xenopus pronephros differentiation as in mammalian nephrogenesis. This allows the dissection of the molecular and cellular events relevant for nephrogenesis in an easy amenable experimental system. Thus, Xenopus pronephros formation can be used to define nephrogenic regulators and to identify the morphogenetic potential of mutated factors associated with renal diseases in humans.
