The present disclosure relates to melon plants that are resistant to the plant disease downy mildew caused by the pathogen. Specifically, the present disclosure relates to melon plants that are resistant to downy mildew disease including a mutated homoserine kinase gene encoding a mutated homoserine kinase protein. The present disclosure further relates to seeds, tissues, cells, or plant parts of the present melon plants, and to methods for identifying downy mildew resistant melon plants.

Downy mildew resistant melon plants

The present invention relates to mutant(spp.) plants including mutant dmr6.1 and dmr6.2 alleles. The mutantplants are resistant to oomycete and fungal pathogens.

Disease resistant petunia plants

The present invention relates toresistantplants wherein said resistance is conferred by a combination of two genes. The present invention further relates to the use of these genes for providingresistantplants and proteins encoded by the present genes.

Disease resistant pepper plants

Described herein are downy mildew resistant genes in sunflower and downy mildew resistance sunflower plants. Specifically, the present invention relates to sunflower plants being resistant to the plant pathogen downy mildew, wherein the plant comprises a downy mildew resistance conferring gene encoding a protein including the amino acid sequence as shown in SEQ ID No. 2 or SEQ ID No. 4 and wherein the expression of the resistance conferring gene is reduced as compared to the expression of said resistance conferring gene in a sunflower plant not being resistant to the plant pathogen downy mildew or the enzymatic activity of said protein is reduced as compared to the enzymatic activity of said protein in a sunflower plant not being resistant to the plant pathogen downy mildew.

Downy mildew resistance providing genes in sunflower

The present invention relates to a plant, which is resistant to a pathogen of viral, bacterial, fungal or oomycete origin, wherein the plant has a reduced level, reduced activity or complete absence of DMR6 protein as compared to a plant that is not resistant to the said pathogen, in particular organisms of the Fungi or the phylum Oomycota. The invention further relates to a method for obtaining a plant, which is resistant to a pathogen of viral, bacterial, fungal or oomycete origin, comprising reducing the endogenous level or activity of DMR6 protein in the plant. In addition, the invention relates to the use of a DMR6 promotor for providing disease resistant plants.
