Compositions and methods for protecting a plant from a pathogen, particularly a fungal pathogen, are provided. Compositions include novel amino acid sequences, and variants and fragments thereof, for antipathogenic polypeptides that were isolated from microbial fermentation broths. Nucleic acid molecules comprising nucleotide sequences that encode the antipathogenic polypeptides of the invention are also provided. A method for inducing pathogen resistance in a plant using the nucleotide sequences disclosed herein is further provided. The method comprises introducing into a plant an expression cassette comprising a promoter operably linked to a nucleotide sequence that encodes an antipathogenic polypeptide of the invention. Compositions comprising an antipathogenic polypeptide or a transformed microorganism comprising a nucleic acid of the invention in combination with a carrier and methods of using these compositions to protect a plant from a pathogen are further provided. Transformed plants, plant cells, seeds, and microorganisms comprising a nucleotide sequence that encodes an antipathogenic polypeptide of the invention, or variant or fragment thereof, are also disclosed.

Compositions and methods are provided for benefiting plant growth. The compositions contain isolated bacterial or fungal strains having properties beneficial to plant growth and development that can provide beneficial growth effects when delivered in a liquid fertilizer in combination with a soil insecticide to plants, seeds, or the soil or other growth medium surrounding the plant or seed. The beneficial growth effects include one or a combination of improved seedling vigor, improved root development, improved plant health, increased plant mass, increased yield, improved appearance, improvedresistance to osmotic stress, improved resistance to abiotic stresses, or improved resistance to plant pathogens. The isolated bacterial strains include those of the Bacillus species including speciessuch as Bacillus pumilus, Bacillus licheniformis, and Bacillus subtilis.

The invention provides methods and compositions related to transgenic plants which incorporate genetic traits of the marine eelgrass Zostera marina. These traits include pathogen resistance, which may be conferred by stimulating zosteric acid biosynthesis.

A pathogen-resistant coating comprising one or more photocatalysts capable of generating singlet oxygen from ambient air. The pathogen-resistant coating may optionally include one or more singlet oxygen traps.

The present disclosure relates, according to some embodiments, to pathogen resistant citrus compositions, organisms, systems, and methods. For example, a composition may comprise a peptide (e.g., a defensin peptide) and / or a nucleic acid (e.g., a defensin nucleic acid). A pathogen resistant citrus plant may comprise, in some embodiments, a defensin peptide and / or an expressable nucleic acid encoding a defensin peptide.

A method of improving the growth and / or pathogen resistance of a plant, comprising the step of exposing at least part of the plant to a transient period of high intensity illumination providing a photon flux at the plant surface having at least one of the following characteristics: (a) a red photon flux comprising at least 100 micromoles photons per square meter per second, and having a wavelength of between 600 and 700 nm; (b) a blue photon flux comprising at least 100 micromoles photons per square meter per second, having a wavelength of between 420 and 480 nm. The Invention also provides apparatus for providing such conditions to growing plants.

Compositions and methods for protecting a plant from a pathogen, particularly a fungal pathogen, are provided. Compositions include amino acid sequences, and variants and fragments thereof, for novel variants of antipathogenic polypeptides generated through DNA shuffling that exhibit improved antipathogenic activity. Polynucleotides that encode the antipathogenic polypeptides are also provided. A method for inducing pathogen resistance in a plant using the polynucleotides disclosed herein is further provided. Compositions comprising an antipathogenic polypeptide or a microorganism comprising an antipathogenic polynucleotide of the invention in combination with a carrier and methods of using these compositions to protect a plant from a pathogen are further provided. Plants, plant cells, seeds, and microorganisms comprising an antipathogenic polynucleotide or polypeptide of the invention are also disclosed.
