GM/Biotech Crops Monthly Report November 2017

 

 

MIT & Harvard lead the way

Scientists at MIT and Harvard have developed machines that can be used to correct errors of single bases to effect corrections in the genetic code. They plan to use this technique to cure diseases like cystic fibrosis and it has been said that we can no longer pretend that the techniques are too dangerous to contemplate. More

Jerusalem artichoke improves salinity tolerance

Cation transporter genes found in Jerusalem artichokes are responsible for its tolerance of salt in the soil and now researchers in China have copied these into the rice genome where they confer improved salinity tolerance and improved grain yield. More

Whitefly-resistant lettuce

An RNAi plasmid engineered in lettuce that affects ion transport in whiteflies has achieved 84-98% mortality in whitefly in tests.  More

GM Soybean oil reduces obesity

Soybean oil is commonly used as cooking oil in many parts of the world and studies have recently shown that oil engineered to have low linoleic acid content (making it more like olive oil) causes less obesity and insulin resistance than conventional soybean oil but with no effect on diabetes or fatty liver. More

 Weighing
Asthma treatment development

Scientists in China have engineered mice to represent a model of asthma in humans.  Then they have used the expressed genes to affect the level of fluid production in response to some antigens.  It is early stages work at the moment but it suggests a novel approach to controlling asthma. More

Easier hybrid wheat development

Researchers at the University of Adelaide have discovered a gene in wheat that when turned off stops self-pollination but still permits cross-breeding.  Moreover, the gene modification is limited to the grandparent stage and does not proceed to the downstream hybrid lines. More

New method of Septoria control in wheat?

Rothamsted has noted that some strains of Septoria fail to infect wheat leaves due to a mutation on one gene that stops the hyphae from developing to penetrate the wheat cell walls.  They are now trying to characterise the protein and will develop a treatment that can be used to block the gene in fungal spores.  More

Amaizin’ rice

Scientists in Oxford have taken the first steps in switching rice from C3 photosynthesis to the more efficient C4 photosynthesis by inserting a gene from maize. Once the ancillary genes required have been identified and spliced in it could offer 50% yield increases in the GM rice.  More

Rust resistance in wheat

Engineering wheat to achieve HIGS (Host-induced gene silencing) is one way of reducing the virulence of rust spores that fall on wheat leaves.  The wheat is engineered to produce the RNAi that switches off essential genes in the growth of the hyphae of the mycelium.  Will the rust be able to mutate to find a way around this defence? More
