Engineered wheat contains double the iron

Problems of iron deficiency could be alleviated with white flour made from the engineered wheat contains twice the typical amount of iron; something that cannot be achieved by normal breeding.
The two genes responsible for the transport of iron were found using the recently published wheat genome. Dr James Connorton, working with Dr Janneke Balk and Dr Cristobal Uauy of John Innes Centre, then used one of these genes to direct more iron into the endosperm, the part of the grain from which white flour is milled.
Iron occurs naturally in wheat, but it is largely found in the outer parts of the grain, the aleurone layer and the seed coat. Unfortunately, these parts of the grain are removed during production of white flour, resulting in low levels of iron in the final product. The endosperm is the inner starchy part of the grain used to make flour. It has very little iron naturally, so white flour made from commercial wheat varieties also contains low levels of iron. With the help of the BRACT Crop Transformation platform the team engineered the wheat so that the endosperm accumulated more iron.
By understanding the mechanisms of iron uptake into the endosperm of the plant, breeders can look at ways of incorporating this knowledge into wheat breeding programmes and work to produce wheat that gives white flour with enhanced iron content.

Could crop varieties that cope in extreme environments thrive in the UK? Would “no-till’ practices from the altiplano work below sea level on the fens? Would on-farm processing from other geographies work here? At a time of great economic, political and environmental change, looking outwards can provide sources of inspiration and innovation.
“Weed control has certainly been changing in the past few years,” says Philip Garford, Managing Director of Garford Farm Machinery. He is set to speak at Agri-Tech’s annual 
A: Our InRow Weeder uses video image analysis techniques to mechanically remove weeds from the inter-row and the crop row between the plants. It can be used on most crops that are planted with regular plant and row spacing, such as lettuce and celery.
A: We deal with variables such as weed types, weed growth stages, soil type, soil moisture levels and crop growth stage. Although machine learning is coming on leaps and bounds, we’re a long way from a machine that will be able to recognise all these factors and adjust to keep working at 100% without error.
A: We designed and manufactured our own sugar beet harvester, which was sold through the late 1980’s, 1990’s and into the 2000’s. The skew bar topper was designed to remove the leaves from the sugar beet, without taking the top off the sugar beet itself, enabling farmers to collect higher tonnage from the crop.
Professor Sir David Baulcombe, head of Cambridge’s Department of Plant Sciences and the project lead for the University, explains: “3CS innovations will generate new crops and new ways of growing crops for food, fuels, industrial feedstocks and pharmaceuticals.
“Too much of our information these days comes from the virtual world and here we can offer an experience that is real and memorable.”
