  • Breeding wildness back into our fruit and veg
    means the wild varieties are unlikely to be a viable option on a large scale Our findings suggest that if we can breed the wild whitefly resistant genes back into our tomatoes either through a selective breeding programme or genetic engineering then it offers a real solution for the commercial tomato industry Project supervisor Dr Barry Brogan also from Newcastle University said the findings also highlighted the importance of maintaining biodiversity There has been growing interest in traditional and wild varieties of fruit and veg driven mainly by people wanting to re capture the tastes of their childhood explains Dr Brogan But actually it s playing a vital role in protecting these older varieties and maintaining biodiversity If we allow our wild species to be lost then we risk losing potentially useful traits that we might need at a later date Explore further Papaya plants reduce the need for pesticides on tomatoes in Florida new study finds More information Novel resistance mechanisms of a wild tomato against the glasshouse whitefly Thomas McDaniel Colin Tosh Angharad Gatehouse David George Michelle Robson and Barry Brogan Agronomy for Sustainable Development Provided by Newcastle University 11 shares feedback to editors Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 Scientists discover hidden galaxies behind the Milky Way Feb 09 2016 3 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves like water Feb 11 2016 2 more Phys org on facebook Relevant PhysicsForums posts The great basic question of science on origin of life 1 hour ago How to create microscope videos 1 hour ago Fly feeling 11 hours ago Why do you get pressure drop in central circulation 11 hours ago Novel Idea on the Origin of Life 12 hours ago Opening the blood brain barrier with collapsing bubbles 21 hours ago More from Biology and Medical Related Stories Papaya plants reduce the need for pesticides on tomatoes in Florida new study finds June 30 2011 Whiteflies can be biologically controlled in Florida greenhouse tomatoes according to a new University of Florida study which helps reduce the need for pesticide applications Galapagos tomato provides key to making cultivated tomatoes resistant to whitefly September 11 2012 The whitefly is a major problem for open field tomato cultivation throughout the world Scientists of Wageningen UR together with a number of partners have discovered genes for resistance to the whitefly in a wild relative Defending food crops Whitefly experimentation to prevent contamination of agriculture November 8 2013 On November 8th JoVE the Journal of Visualized Experiments will introduce a new technique to aid in the development of defenses against diseases threatening food crops worldwide The method published under the title Transmitting Whitefly confused by cacophony of smells April 28 2014 Bombarding pests with smells from many different plants temporarily confuses them and hinders their
