Banana Streak Disease May be Disabled

Bananas continue to be a target plant for breeding using new technologies.

The latest is a development that eliminates banana streak virus disease from the plant as well as preventing reinfection, using various gene editing options.  This disease is a major problem in parts of west Africa.

Developments like this continue to be implemented and offer significant potential for food crops especially in areas where some crops are staple foods.......and lowered production can be devasting to the local population.

Yes, there are some scientific and policy issues to be considered but there seems to be a better understanding that maybe these approaches with genetic engineering [as a broad approach] offer a real way forward in better plant production.

We are likely to see expanded use of the CRISPR gene technology across many crops or even less well developed or unexploited species to develop newer varieties for modern agriculture and improve overall crop productivity.

EU Court of Justice Ruling on Plant Breeding Innovation

On July 25 the European Union (EU) Court of Justice ruled that plants resulting from some of the latest plant breeding innovations, including targeted mutagenesis (i.e. gene editing) such as CRISPR, are considered genetically modified organisms (GMOs). It is important to note that the ruling is an interpretation of existing EU law. It is not a scientific assessment, nor an expression or statement of policy by the EU’s political bodies. This interpretation is at odds with decisions and interpretations made elsewhere in the world, including here in Australia, US, South America and Israel.   Summary  The EU Court of Justice has issued its long-awaited decision on the regulatory status of plants resulting from some of the latest plant breeding innovations. This determines whether they can practically be taken up by researchers, universities, breeders and farmers in the EU. The ruling’s line of argument is based almost entirely on the breeding process (technology involved) and does not differentiate between product categories based on the outcome of these processes. The ruling puts forward a purely process-based approach after an EU specific point in time (2001; the time of adoption of the EU GMO Directive). Organisms obtained by means of mutagenesis which have “conventionally” been used and have a long safety record will continue to be exempt. This exemption would apply to the “classical”, random mutagenesis breeding methods using chemicals or radiation. In Australia, the current review of the Gene Technology Regulations and the National Gene Technology Scheme will provide regulatory clarity on plants and animals derived from the latest breeding methods for Australian industry and public-sector researchers. ABCA’s Statement of Principles on Regulatory Oversight of New Breeding Techniques is available on the ABCA website.   Further information: The Court of Justice of the EU Ruling on Case  C-528/16 and associated Press Release.

The media links above would say it all - most if not all are a bit stunned at the decision. No doubt the anti GM urgers will  applaud the decision, but it will have wide implications - or will it?

GM Bt Cotton and Aphids - Law of Unintended Consequences

Recent field trials seem to have confirmed that BT cotton has had some unintended outcomes with aphids proliferating, and damaging cotton crops.

It seems that the Bt gene has prevented production of natural plant defence chemicals which are stimulated by caterpillar attacks on the plants, and these chemicals in turn deter aphids.

The story is more complex but the link provides a reasonably neat summary.

Up until recently it seemed that the GM cotton story was one that generally had been a very successful option with pesticide use reducing substantially on Bt cotton varieties.

It is not totally clear if economic damage is occurring but it does seem likely that aphids are now a pest in some situations and in some areas.
