Abstract: The present invention is directed to melon plant and seed, namely of C. melo subsp. melo. which are resistant to ToLCNDV, comprising in their genome introgressed sequences from C. melo subsp. agrestis var. acidulous conferring resistance to said virus, when present homozygously. The introgressed sequences are preferably characterized by defined alleles of SNPs on chromosome 11, inter alia allele A of SNP Melon_sbg_14207_58 (SEQ ID No:9). The introgressed sequences can be chosen from those present in the genome of a plant of ToLR1 accession number NCIMB 42506. The invention is also directed to parts of these resistant plants, as well as progeny, to the use of these plants for introgressing the resistance in another genetic background, as well as to different methods for obtaining resistant melon plants or seeds.

Abstract: Isolated genes and amino acid sequences encode methylketone synthase 2 (MKS2) enzymes from tomato plants, including, ShMKS2 and SlMKS2. When expressed recombinantly in bacteria and other host cells, the MKS2 enzymes produce methylketones of various carbon chain lengths ranging from C7 to C20 from 3-ketoacyl intermediate substrates. Methylketones are known to have important roles in protecting plants against pests, and also as flavor compounds, and can be used as stockfeed in the chemical industry.
