Tomato plant resistant to tomato yellow leaf curl virus, powdery mildew, and nematodes

The present invention relates to Solanum lycopersicum (S. lycopersicum) plants with resistance to Tomato Yellow Leaf Curl Virus (TYLCV), powdery mildew (PM) and nematodes. According to the invention, the resistances are provided by coupling in cis on the same chromosome the OL4 gene conferring resistance to PM and nematodes and TY1 gene conferring resistance to TYLCV, without coupling the Mi-1 gene conferring resistance to nematodes in cis with said OL4 gene conferring resistance to PM and nematodes and TY1 gene conferring resistance to TYLCV. The genes can be present homozygously or heterozygously in the genome of the S. lycopersicum plants, and they confer resistance to TYLCV, PM and nematodes. The present invention also provides methods for making such plants, and to methods of detecting and/or selecting such plants.

PUCCINIA RESISTANCE GENE
20220403408 · 2022-12-22 ·

The present invention relates to a plant which has integrated into its genome an exogenous polynucleotide encoding a polypeptide which confers resistance to at least one strain of Puccinia graminis.

TBRFV RESISTANT TOMATO PLANT
20220389442 · 2022-12-08 ·

The invention relates to a Solanum lycopersicum plant that is resistant to TBRFV, which plant comprises a QTL on chromosome 11, and/or a QTL on chromosome 12, and/or a QTL on chromosome 6. The presence of the QTL on chromosome 11 can be identified by use of at least one of the markers selected from the group comprising SEQ ID NOS: 1, 9, and 2-8; the presence of the QTL on chromosome 12 can be identified by use of at least one of the markers selected from the group comprising SEQ ID NOS: 10, 15, and 11-14; and the presence of the QTL on chromosome 6 can be identified by use of at least one of the markers selected from the group comprising SEQ ID NOS: 16, 25, and 17-24. 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 42879, NCIMB 42880, NCIMB 42881, NCIMB 42882, NCIMB 42883, NCIMB 42884, NCIMB 42885, NCIMB 42886, NCIMB 42887, NCIMB 42888, NCIMB 42889, or NCIMB 42890.

Genetic basis for <i>Pythium </i>resistance

The present invention relates to a Cucumis sativus plant which may comprise a QTL, a copy number variant region, at least two copies of an ERF gene, or a mutation leading to increased expression of an ERF gene, which leads to Pythium resistance. The invention further relates to propagation material suitable for producing such Cucumis sativus plant. The invention also relates to a method for producing such Cucumis sativus plant and to methods for identification and selection of such a plant. In addition, the invention relates to a marker for identification of the QTL or copy number variant region, or for identification of the presence of at least two copies of an ERF gene resulting in Pythium resistance in Cucumis sativus, and to use of said marker. The invention also relates to seed which may comprise the QTL, copy number variant region, at least two copies of an ERF gene, or a mutation leading to increased expression of an ERF gene, which leads to Pythium resistance in the plant grown from such seed.

QTLs for powdery mildew resistance in melon

The present invention relates to genetic elements comprising powdery mildew-conferring QTLs derived from a plant of the species Cucumis melo, or powdery mildew-conferring part or variant thereof. The invention also relates to markers for identification of said QTLs, use thereof and methods for producing plants with increased resistance to powdery mildew and the plants thus obtained.

<i>Baccatum cytoplasmic </i>male sterility with female fertile flowers in <i>Capsicum annuum</i>

The present disclosure provides Capsicum annuum BCMS plants exhibiting uniform female fertility. Such plants comprise novel introgressed genomic regions associated with uniform female fertility from Capsicum annuum on chromosome 6. In certain aspects, compositions and methods for producing, breeding, identifying, and selecting plants or germplasm with a uniform female fertility phenotype are provided.

NOVEL GENETIC LOCI ASSOCIATED WITH RUST RESISTANCE IN SOYBEANS

The present invention provides methods and compositions for identifying, selecting, and/or producing a soybean plant or germplasm resistant to Asian soybean rust using markers, genes and chromosomal intervals derived from Glycine max strain SX6907. Asian soybean rust resistant soybean seeds, plants, and germplasms are also provided.

ACCELERATED METHOD FOR GENERATING TARGET ELITE INBREDS WITH SPECIFIC AND DESIGNED TRAIT MODIFICATION

The present disclosure provides a method of generating a new trait converted elite cultivar through a method of breeding. For instance, the method involves the use of parent plants, which are respectively the traited variant of the parents of the non-traited elite cultivar and estimating a minimum population size necessary to generate a progeny plant comprising the desired trait and sharing a sufficiently high identity by descent with the non-traited elite cultivar to ensure replication and equivalency of general performance. The present method may be used to generate an elite cultivar in fewer generations, thereby accelerating new line production, and reducing costs. The present method may also be used to generate non-traited variants of traited lines.

Genetic markers associated with drought tolerance in maize

The present invention relates to methods and compositions for identifying, selecting and/or producing a maize plant or maize plant part having increased yield under non-drought conditions, increased yield stability under drought conditions, and/or increased drought tolerance. A maize plant or maize plant part, including any progeny and/or seeds derived from a maize plant or germplasm identified, selected and/or produced by any of the methods of the present invention is also provided.

<i>Brassica oleracea </i>plants with downy mildew resistant curds or heads

The present disclosure provides Brassica oleracea plants having curds or heads exhibiting increased resistance to downy mildew. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Brassica oleracea MYCOCLP. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.
