GM/Biotech Crops Monthly Report April 2018
How to triple the number of sorghum grains
Sorghum has two types of flower – one that produces grains and one that does not. Researchers at Cold spring Harbour Laboratory have found a simple genetic modification that allows both types of flower to produce grains. They don’t say if it actually increases yield but do say that a similar increase in grain numbers might also be possible in wheat, maize and rice. More

|GM Sugarcane in Brazil
One reason for the reticence of British Sugar to embrace GM sugarbeet was the fear that it might cause big sugar buyers to switch to sugarcane. Brazil is now starting to grow and process sugarcane engineered to be resistant to cane borer and so this worry is removed. Will GM sugar beet soon be grown in the UK like it is in America? More

|Tobacco for healthy living
Tobacco is the cause of many lung cancers but now researchers in Spain are modifying the tobacco plant to use it as a biofactory for the production of many different health-promoting substances such as vaccines and anti-inflammatory agents. The RUVID website gives details but only in Spanish. More
|Switching on ‘silenced’ genes
Not all genes in a genome are active. Now a team at UGA has found that by introducing a human gene into Arabidopsis they can selectively switch on these silenced genes, making possible a greater diversity of biotypes than was previously possible. One has to ask why natural selection switched them off in the first place? More

Everyone knows that green potatoes are poisonous but now a team at Kobi University in Japan has used CRISPR-Cas9 editing to knock out the gene that causes the production of steroidal glycoalkaloids. This causes an increase in the accumulation steroidal saponins which are apparently valued by the pharmaceutical industry. More

|More on GM Sugarcane
Building on the cane borer resistance mentioned above, Monsanto has produced a Stacked Trait that adds glyphosate tolerance to this insect resistance (i) while researchers at the University of Punjab in Pakistan are developing transgenic sugarcane that is resistant to sugarcane mosaic virus (ii). (i) More (ii) And More

|Why some weeds quickly develop resistance to glyphosate
Chromosomes are not the only DNA in town! The weed Palmer amaranth also has genes that have escaped the chromosomes and formed separate self-replicating circular DNA structures. These structures contain versions of the gene blocked by glyphosate but, because there are hundreds of these structures in each cell, it is easier for the cell to overcome the effects of the glyphosate.

|Golden Rice at last!
Golden Rice, which helps overcome vitamin A deficiencies in rice-based diets and thus alleviate blindness, has long been cited as a benefit of GM technology. Now, finally, it is being grown in Canada, Australia and New Zealand where its health benefits are less relevant. More

|Tomatoes that fight hypertension
According to WHO, 30% of the world population is suffering from hypertension. Splicing a gene from Amaranth into tomatoes has resulted in a plant that produces amarantin, a protein with similar therapeutic effects to captopril which is currently used to treat hypertension. The next step is to test the engineered tomatoes on humans suffering from hypertension. The following website gives details but only in Spanish. More
|Isolation of Rice Blast
Rice blast is a fungal disease that is claimed to destroy 30% of the world’s annual rice crop. Once inside a cell it spreads throughout the plant via the plant’s intercellular channels but a team led by Exeter University has found that inhibiting a single protein in traps the disease in the infected cell and stops it spreading throughout the rice plant. More
|Beer without hops
Growing hops requires a lot of land, fertiliser and water but hops are essential in the production of beer. Now a team at Berkeley University in California have engineered brewer’s yeast to produce the flavour components normally derived from hops. More
