The present invention relates to plants of the genus Catharanthus containing a broad spectrum genetic resistance to Phytophthora. In particular, the present invention relates to a Catharanthus roseus plant containing a broad spectrum genetic resistance to P. nicotianae.

Methods and materials for modulating cold tolerance levels in plants are disclosed. For example, nucleic acids encoding cold tolerance-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased cold tolerance levels and plant products produced from plants having increased cold tolerance levels.

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.

The present disclosure provides Capsicum annuum plants exhibiting increased resistance to Leveillula taurica. Such plants comprise novel introgressed genomic regions associated with disease resistance on chromosome 6. In certain aspects, compositions and methods for producing, breeding, identifying, and selecting plants or germplasm with an increased disease resistance phenotype are provided.

The present invention is directed to a commercial tomato, namely S. lycopersicum plant, which is resistant to an arthropod pest comprising in its genome introgressed sequences from S. galapagense conferring resistance to said arthropod pest, wherein the introgressed sequences are chosen from those present in the genome of a plant of the line TUT115 NCIMB accession number 42109. The commercial tomato of the invention is preferably resistant to ToMV (Tomato Mosaic Virus). The introgressed sequences are preferably found at one or more of the loci defined by the following SNP markers: SNP solcap_snp_sl_18619 on chromosome 1 and SNP solcap_snp_sl_12348 on chromosome 1.

This disclosure describes clubroot (CR) resistant plants; in particular, CR resistant Brassica plants, including B. napus. CR resistant plants include all or part of at least one genomic sequence of a B. napus parent genome that confers clubroot resistance. The genomic sequence may be a genomic sequence from chromosome N03, chromosome N04, and/or chromosome N08.

Disclosed herein are engineered antimicrobial peptides (e.g, HTH peptide or AAPs) and methods of using such peptides to treat pathogenic infections, such as HLB disease and X. fastidiosa, in plants, such as citrus plants and grape plants. The engineered antimicrobial peptides may be derived from amphipathic helical peptides. The engineered antimicrobial peptides disclosed herein may be formed by coupling two or more amphipathic helical peptides. An engineered antimicrobial peptide may include a first amphipathic helical peptide coupled with a second amphipathic helical peptide by a linker domain forming a helix-turn-helix scaffold formation. Such amphipathic helical peptides may be endogenous to a target host, such as a plant (e.g., a citrus plant or grape plant).

The invention provides low erucic, clubroot resistant Brassica plants, plant material and seeds, characterized in that these products harbor a specific CrS clubroot resistance locus in their genome. Tools are also provided which allow detection of the CrS clubroot resistance locus.

Provided is a Cannabis plant exhibiting altered tetrahydrocannabinolic acid (THCA) and/or cannabidiolic acid (CBDA) content. The plant includes a modified genomic locus involved in tetrahydrocannabinolic acid synthase (THCAS) and/or cannabidiolic acid synthase (CBDAS) gene expression, the genomic locus includes at least one targeted nucleotide modification within a regulatory region modulating the expression of at least one allele of the THCAS and/or CBDAS genes. Further provided are methods for producing the aforementioned Cannabis plant.
