Enhancing powdery mildew resistance in wheat

August 17th, 2017 / ISAAA, US

Wheat (Triticum aestivum L.) suffers significant yield losses due to powdery mildew, a major fungal disease caused by Blumeria graminis f. sp. tritici (Bgt). The enhanced disease resistance1 (EDR1) gene plays a negative role in the defense response against powdery mildew in Arabidopsis thaliana, making EDR1 a target for improving …

Scientists biofortify wheat to produce flour with more iron

July 13th, 2017 / ISAAA, US

Researchers from the John Innes Centre (JIC) have developed a variety of wheat that has high levels of iron. This new biofortified variety could help decrease the number of people with iron deficiency around the world.
Wheat contains iron in parts that are removed before milling. With the use of the …
