新的抗病粮食作物的前景

研究人员发现了显著的广谱抗性的遗传基础的病毒感染,在世界的某些地方,是最重要的病原体影响叶和可耕芸苔属植物作物包括西兰花、花椰菜、卷心菜、甘蓝、瑞典和油料强奸。他们已经测试了抗植物对一系列不同的病毒株来自世界各地,到目前为止,没有应变能够克服阻力。广告由谷歌超级细菌与抗生素滥用抗生素品种耐药疾病——www.saveantibiotics.org研究所谓的芜菁花叶病毒(TuMV),由华威大学的约翰·沃尔什博士和资助BBSRC作物科学计划的框架下,提出了与先正达合作的新种子。沃尔什博士说“TuMV原因真的长相凶恶的黑色坏死斑点的植物它感染——“一个痘”蔬菜!这可能会导致重大收益损失,常常使整个作物不适合销售。在最好的情况下,严重影响芽甘蓝领域可能会提供一些动物饲料,但这些蔬菜不会吸引大多数购物者。病毒尤其难以控制,因为它传播如此之快的植物昆虫”沃尔什博士和他的团队发现了主要基因参与抵抗TuMV,发现它创建的阻力是全新的。利用这一知识,他们发现可以确定植物的固有电阻可以用来加快育种进程和发展商业品种,抗TuMV。华威大学的团队正在与行业合作伙伴先正达种子繁殖阻力成白菜。他们希望在未来做同样的事情与其他作物如花椰菜、白菜和甘蓝。 Peter van der Toorn, R&D Lead Leafy Crops, Syngenta Seeds Vegetables said "Working in partnership with academic researchers is very important for us. Through such collaborations it's possible to take an idea from pre-commercial research and turn it into a new variety that can benefit the consumer and boost our contribution to the UK economy. We are very excited to be working together with academics at the University of Warwick to breed varieties with improved resistance to Turnip mosaic virus." Professor Douglas Kell, BBSRC Chief Executive said "Bioscience research in all its forms has always given rise to developments that have impacts in society – whether predicted or serendipitous. Such developments need a structure through which to realise their potential and a partnership such as this one between the University of Warwick researchers and Syngenta will be important to ensure that resistance to diseases is incorporated into commercial crop varieties. These new resistant varieties would then be available to contribute towards future food security." Provided by Biotechnology and Biological Sciences Research Council (news : web)
