Pathogenresistente Pflanzen und Verfahren zu ihrer Herstellung

摘要

The invention pertains to the isolation of new pathogen-induced cDNA clones as well as a method for producing pathogen-resistant plants, wherein a chimeric gene construct consisting of an active promoter, a region coding virus-induced proteins (VIP proteins) and a polyadenylation signal is introduced into the genetic material of the plant. The new VIP protein genes were isolated from transgenic tobacco plants that have an elevated resistance to virus. The VIP proteins represent a new class of PR proteins. The invention also pertains to new DNA sequences which code for the VIP proteins as well as plants and parts of plants that have genetic material altered using the claimed method. The new plants have a higher resistance to pathogens. The invention has industrial application in agriculture and genetic engineering.
