“…Nevertheless, only particular cases of intragenesis (hardly distinguishable from cisgenesis) could lead to new combinations of genetic material that occur naturally so that crops obtained through this approach are unlikely to be accepted as non-GM. [4][5][6]) have argued that cisgenesis should be excluded from the provisions of the current GMO regulations. However, GMO regulations worldwide are slightly different and interpretation is often a matter of nuances.…”

Abstract:Organic farming prohibits the use of genetically modified organisms (GMOs) inasmuch as their genetic material has been altered in a way that does not occur naturally. In actual fact, there is a conventional identity between GMOs and transgenic organisms, so that genetic modification methods such as somatic hybridization and mutagenesis are equalized to conventional breeding. A loophole in this system is represented by more or less innovative genetic engineering approaches under regulatory discussion, such as cisgenesis, oligonucleotide-directed mutagenesis, and antisense technologies, that are redefining the concept of GMOs and might circumvent the requirements of the GMO legislation and, indirectly, of organic farming.

Summary Whilst most studies reviewing the reliance of global agriculture on insect pollination advocate increasing the ‘supply’ of pollinators (wild or managed) to improve crop yields, there has been little focus on altering a crop's ‘demand’ for pollinators.Parthenocarpy (fruit set in the absence of fertilization) is a trait which can increase fruit quantity and quality from pollinator‐dependent crops by removing the need for pollination.Here we present a meta‐analysis of studies examining the extent and effectiveness of parthenocarpy‐promoting techniques (genetic modification, hormone application and selective breeding) currently being used commercially, or experimentally, on pollinator‐dependent crops in different test environments (no pollination, hand pollination, open pollination).All techniques significantly increased fruit quantity and quality in 18 pollinator‐dependent crop species (not including seed and nut crops as parthenocarpy causes seedlessness). The degree to which plants experienced pollen limitation in the different test environments could not be ascertained, so the absolute effect of parthenocarpy relative to optimal pollination could not be determined. Synthesis and applications. Parthenocarpy has the potential to lower a crop's demand for pollinators, whilst extending current geographic and climatic ranges of production. Thus, growers may wish to use parthenocarpic crop plants, in combination with other environmentally considerate practices, to improve food security and their economic prospects.

“…The application of cisgenesis, the use of genes from the host or related species but introduced by biolistics or some other mechanisms that does not involves introduction of microbial sequences (Espinoza et al, 2013;Holme, Wendt, & Holm, 2013;Manoj & Shekhawat, 2014;Telem et al, 2013), may aid in removing some of the hostility to the application of this technology. There will undoubtedly be more examples of new plant species with resistance developed against regional viruses, as well as against new viruses that have yet to be described.…”
