[QUOTE="Agriland RSS, post: 6396628, member: 105608"] [img]https://s3-eu-west-1.amazonaws.com/files.thefarmingforum.co.uk/images/agrilanduk.JPG[/img] Written by Rachel Martin UK scientists have found that engineering bread wheat to have fewer pores on their leaves makes more efficient use of water, potentially helping farmers facing more frequent drought conditions Scientists at the University of Sheffield’s Institute for Sustainable Food found that engineering bread wheat to have fewer stomata helps the crop to use water more efficiently while maintaining yields. On average, it takes more than 1,800L of water to produce 1kg of wheat. As droughts become more common even in the UK, farmers will need to produce more food than ever with even fewer resources to feed a growing population. Wheat uses stomata to regulate its intake of carbon dioxide for photosynthesis, as well as the release of water vapour. When water is plentiful, stomatal opening helps plants to regulate temperature by evaporative cooling – similar to sweating. In drought conditions, plants normally close their stomata to slow down water loss – but wheat with fewer stomata has been found to conserve water even better, and can use that water to cool itself. During the study, which has been published in the [I]Journal of Experimental Botany[/I], the scientists grew wheat in conditions similar to those expected under climate breakdown – with higher levels of carbon dioxide and less water. Compared to conventional wheat, the engineered plants used less water while maintaining photosynthesis and yield. The research builds on the Institute for Sustainable Food’s work to develop climate-ready rice, which found that rice with fewer stomata used 40% less water than conventional breeds and was able to survive drought and temperatures of 40ºC. Julie Gray, professor of Plant Molecular Biology at the Institute for Sustainable Food, said: “Wheat is a staple food for millions of people around the world – but as extreme droughts become more frequent, farmers face the prospect of dwindling yields. [INDENT] Developing wheat that uses water more efficiently will help us to feed our growing population while using fewer natural resources – making our food systems more resilient in the face of climate breakdown. [/INDENT] In a separate study published in[I] Plant, Cell and Environment[/I], scientists at the institute also found that plants engineered to have fewer stomata are less susceptible to diseases. They hope to be able to replicate these findings in crops such as wheat and rice.
