研究人员正在利用土壤真菌的一种天然蛋白作为使杂草叶细胞自杀的潜在的除草剂,在温室试验中,这种大规模细胞自杀可在24h内杀死植物叶片。美国农业研究局植物生理学家Bryan Bailey首次发现了一种能够用于诱导超敏感反映的叶片除草剂的蛋白质。五年前,他们在真菌Fusarium oxysporum的分泌物中首次发现了这种叫做Nepl的蛋白质。这种真菌的某些菌种可以导致使玉米、棉花、西红柿及其它作物减产的枯萎病。然而,通过移除F.oxysporum这种制造蛋白的基因,
Researchers are using a natural protein of soil fungi as a potential herbicide to kill weed leaf cells, a large cell suicide that kills plant leaves in 24 hours in greenhouse experiments. Bryan Bailey, a plant physicist for the Bureau of Agricultural Research, for the first time, discovered a protein that can be used to induce hypersensitive leaf-blade herbicides. Five years ago, they first discovered the protein called Nepl in the secretions of the fungus Fusarium oxysporum. Certain species of this fungus can cause blight that reduces corn, cotton, tomatoes and other crops. However, by removing the gene for making proteins such as F. oxysporum,
