The present invention relates to an allele designated alpha-CMV which confers resistance to CMV when present in a spinach plant, wherein the protein encoded by said allele is a CC-NBS-LRR protein that comprises in its amino acid sequence: a) the motif “MAEIGYSVC” (SEQ ID NO: 22) at its N-terminus; and b) the motif “KWMCLR” (SEQ ID NO: 23); and c) an LRR domain that has in order of increased preference at least 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID NO: 10. The allele has a genomic nucleotide sequence which in order of increased preference has at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID NO: 1. The invention further relates to plants comprising the allele and to various methods involving the allele.

Compositions and methods for enhancing disease resistance in plants are disclosed.

The present invention relates to a cultivated melon (Cucumis melo spp. melo) plant resistant against Tomato Leaf Curl New Delhi virus (ToLCNDV), which comprises QTL-1 in its genome, and which QTL-1 confers resistance against Tomato Leaf Curl New Delhi virus (ToLCNDV). The invention further provides progeny, fruit, seeds, propagation material and food products from the plant. The invention also provides markers for the identification of QTL-1, as well as a method for testing a melon (Cucumis melo spp. melo) plant for the presence of QTL-1 in its genome and a method for selecting or identifying a melon plant resistant against ToLCNDV. Also provided is a method for producing a melon (Cucumis melo spp. melo) plant which is resistant against Tomato Leaf Curl New Delhi virus (ToLCNDV).

The present invention relates to ToLCNDV resistant melon plants comprising one or two introgression fragments in their genome.

Disclosed are peptides that induce an active plant response, but not a hypersensitive response, when applied to plant tissue. These peptides also preferably exhibit improved solubility, stability, resistance to chemical degradation, or a combination of these properties. Use of these peptides or fusion polypeptides, or DNA constructs encoding the same, for modulating plant biochemical signaling, imparting disease resistance to plants, enhancing plant growth, imparting tolerance to biotic stress, imparting tolerance and resistance to abiotic stress, imparting desiccation resistance to cuttings removed from ornamental plants, imparting post-harvest disease or post-harvest desiccation resistance to a fruit or vegetable, or enhancing the longevity of fruit or vegetable ripeness are also disclosed.

The present invention relates to a tomato, Solanum lycopersicum, plant that is resistant to Tobamovirus, wherein the plant comprises one or more genomic sequences conferring Tobamovirus resistance. More specifically the invention relates to a tomato plant that is resistant to Tomato Brown Rugose Fruit Virus (TBRFV). The present invention further relates to a genomic sequence or locus providing resistance to Tobamovirus. In addition, the present invention relates to methods for proving a tomato plant that is resistant to Tobamovirus.
