The present invention relates to a modified FBXL13 gene which leads to a plant showing resistance to a virus belonging to the Torradovirus genus. The invention also relates to a plant belonging to the Solanaceae family comprising the modified FBXL13 gene. The modified FBXL13 gene of the invention provides a plant showing resistance to a virus belonging to the Torradovirus genus when compared to plants not comprising the modified FBXL13 gene. The invention further relates to the use of the modified FBXL13 gene for the identification and development of a plant belonging to the Solanaceae family showing resistance to a virus belonging to the Torradovirus genus.

The invention relates to a Solanum lycopersicum plant that is resistant to TBRFV, which plant comprises a QTL on chromosome 11 between SEQ ID NO: 1 and 53. The presence of the QTL on chromosome 11 is identified by use of at least one of the markers selected from the group comprising SEQ ID NOS: 4 to 52. The QTL is as comprised in the genome of a Solanum lycopersicum plant representative seed of which was deposited with the NCIMB under deposit number NCIMB 42882, NCIMB 42885, NCIMB 42887, or NCIMB 42890.

The present invention relates to Tomato spotted wilt virus, or TSWV, resistant plants and especially plants of the genus Cichorium such as leaf chicory, endive, radicchio, Belgian endive, French endive, and witloof. The invention further relates to methods for identifying and providing the present plants using genomic nucleic acid sequences identified herein. Specifically, the present invention relates to plants being resistant to Tomato spotted wilt virus, or TSWV, wherein the plants comprise a first resistance providing genomic fragment comprising one or more nucleic acid sequences selected from the group consisting of SEQ ID No. 2, SEQ ID No. 4, SEQ ID No. 6, SEQ ID No. 8, SEQ ID No. 10, SEQ ID No. 12, SEQ ID No. 14, SEQ ID No. 16, SEQ ID No. 18, SEQ ID No. 20, SEQ ID No. 22, SEQ ID No. 24, and SEQ ID No. 26.

The present invention addresses the problem of providing: a solanaceous plant and a solanaceous plant cell that have resistance to tomato spotted wilt virus (TSWV) and that have the property of inhibiting TSWV infection, the property of suppressing the propagation proliferation of TSWV after infection, and/or the property of suppressing the onset of the symptoms of TSWV infection; and a method for producing the solanaceous plant. The present invention provides a solanaceous plant that has resistance to TSWV, in which at least one gene selected from the group consisting of receptor-like kinase RLK genes and homologous genes thereof has a mutation, and in which as a result of the mutation, either the expression of the gene having the mutation is suppressed or a protein encoded by the gene having the mutation is non-functional with respect to TSWV.

The invention relates to a Solanum lycopersicum plant comprising in its genome QTLs confering to the plant an improved phenotype corresponding to foliar and/or fruit tolerance and/or resistance to Tomato Brown Rugose Fruit virus, with respect to a corresponding plant devoid of said QTLs, and wherein said QTLs are chosen from those present in the genome of a plant of the seeds HAZTBRFVRES1 NCIMB accession number 42758. The QTL are preferably characterized by defined alleles of different SNPs on chromosome 6, 9 and 11. The invention is also directed to parts of these plants with improved phenotype, as well as progeny, to the use of these plants for introgressing the improved phenotype in another genetic background, as well as to different methods for obtaining tomato plants or seeds with increased foliar and/or fruit tolerance or resistance to Tomato Brown Rugose Fruit virus.

The invention provides a compositions and methods for controlling phenotypic traits in plants. Genes of interest are placed under the control of a gene switch to allow inducible control or expression of a gene of interest “on-demand” by treatment of the plant with a chemical ligand.

The present disclosure provides plant transformation vectors, T-DNA insert regions, and transformed plants. The vectors are designed to be a binary vector for use in plant transformations for such as potato. The transformed plants are characterized in that they contain the T-DNA insert region comprising stacked expression cassettes and the corresponding phenotype. The present disclosure also provides methods for identifying genetic material in transformed plants, including in food products made from such plants. The disclosure further relates to the materials and/or means for detecting plant transformation events and methods for detecting presence of plant transformation events.

A watermelon plant and seed, namely of Citrullus lanatus, which are resistant to geminiviruses, especially to begomoviruses including Watermelon chlorotic stunt virus (Wm CSV), comprising in their genome introgressed sequences from Citrullus colocynthis conferring tolerance to said viruses, when present homozygously. More specifically, the invention also discloses molecular genetic markers, linked to the recessive genetic locus conferring tolerance to geminiviruses comprising A Citrullus lanatus seed having in its genome introgressed sequences from Citrullus colocynthis conferring tolerance to geminiviruses only when present homozygously, wherein said introgressed sequences are located on homologous chromosome 6, within the chromosomal region delimited by nucleotides 1-2,255,000.

Orthotospovirus virions travel through the thrips foregut and enter midgut epithelial cells through the interaction between virus glycoproteins and cellular receptors with several protein motifs thought to be involved in the interaction. Single, double and triple mutant polypeptides in the soybean vein necrosis virus (SVNV)/Neohydatothrips variabilis system are provided herein and several are shown to block viral transmission from the thrips to the soybean plants. Methods for inhibiting viral transmission using these polypeptides or constructs comprising polynucleotides encoding peptides are also provided herein.

In order to provide tobacco resistant to a virus, tobacco in accordance with the present invention is arranged such that: (i) a translation initiation factor eIF(iso)4E protein which is non-functional with respect to a virus is produced or (ii) expression of a translation initiation factor eIF(iso)4E gene is suppressed; and (a) a translation initiation factor eIF4E2 protein, which is non-functional with respect to a virus, is produced or (b) expression of a translation initiation factor eIF4E2 gene is suppressed.
