Methods and means for generating microbial disease resistant plants

摘要

Described are genes and chimeric genes encoding anti-microbial peptides. These genes can be used to generate transgenic plants with an improved resistance to, for example, plant pathogenic fungi. Alternatively, the peptides encoded by these genes can be applied as agrochemical formulations to plants suffering from microbial diseases such as fungal diseases.

主权项

1. A chimeric gene comprising the following operably linked DNA elements:
a) a plant expressible promoter, b) a DNA region encoding a polypeptide selected from the group consisting of SEQ ID NO:4, SEQ ID NO:2, and a homologue of SEQ ID NO:2 having at least 95% sequence identity to SEQ ID NO:2, wherein the polypeptide has antifungal activity, and c) a 3′ end region comprising transcription termination and polyadenylation signals functioning in cells of a plant, wherein the plant expressible promoter is heterologous to the DNA region.
