GM/Biotech Crops Monthly Report February 2018
Improving cassava crops in Africa
The shoots of cassava are pruned before harvest begins and this pruning triggers the beginning of starch breakdown in the roots. A new cultivar generated by ETH Zurich uses RNAi to inhibit this degradation of starch and field trials are about to commence. The harvested roots will be destroyed before it can enter the food supply chain. More
|Possible enhancement of some cereal yields
Setaria viridis is a grass related to maize, sorghum and sugarcane. Researchers at Donald Danforth have found a way of converting the sterile bristles in the seed head to spikelets that produce flowers and grain and that disruption of the site can cause it to produce two rather than just one grain site. If this can be achieved in crops such as millet it could offer a technique to increase yields in all these crops. More

|European Union authorises six GM crops
Six GM crops are approved for food and feed use in Europe but not for cultivation and so the products of these crops can be imported for food and feed use but not (yet?) grown here. The crops are four soybean varieties, one maize crop and one oilseed rape. All are engineered to be tolerant of various herbicides, mainly glyphosate and glufosinate but also including other herbicide groups. More

|Rust resistance in wheat
wheat has resistance to some strains of rust and now a collaboration between scientists in Sydney, Rothamsted and Minnesota have identified how rusts overcome this resistance. It means that the development of further rust resistance in wheat can now be targeted by the modification of specific genes. More

|Speed breeding for wheat
No, not speed dating but speed breeding. By growing plants under continuous light the life cycles proceed more quickly and early reproduction in the plants. More

|Gene editing is not the same as GM
The European Court of Justice has rules that gene-edited plants should not be subject to the same stringent laws as GM crops. Could this allow some progress with crops in the EU. More

|Hand-held DNA sequencer
Sequencing human DNA took 13 years of a collaborative effort of labs around the world and was achieved in 1990 but now it can be done with a hand-held device. While the first applications are likely to be medical uses, it must surely reach crop protection quickly, enabling farmers to identify, e.g. the race of rust affecting their wheat. More
