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

Provided herein is a Cucumber plant () which provides fruits having an improved shelf life, wherein said plant comprises a stay green gene providing the improved fruit shelf life, wherein said stay green gene encodes a protein comprising the amino acid sequence as shown in SEQ ID No. 2, or amino acid sequences with more than 90% identity, preferably more than 94% identity, more preferably more than 96% identity, even more preferably more than 98% identity; and wherein the expression of said stay green gene is reduced as compared to the expression of said stay green gene in a cucumber plant not providing fruits having an improved shelf life or the enzymatic activity of said protein is reduced as compared to the enzymatic activity of said protein in a cucumber plant not providing fruits having an improved shelf life.
