Abstract: The present invention relates to the compositions comprising algae, specifically Spirulina platensis and Chlorella, and their use for the treatment of crops, such as fruits. vegetables and arable crops against heat stress, especially sunburn.

Abstract: A composition for coating plant seeds that can promote the initial plant growth and/or that can promote the plant growth under stress conditions is provided. The composition for coating plant seeds includes allantoin, an amino acid, and an agriculturally acceptable carrier. The amino acid may be L-tryptophan. Coated seeds include plant seeds and, on the surface of the seeds, a composition including allantoin and an amino acid.

Abstract: A composition for coating plant seeds that can promote the initial plant growth and/or that can promote the plant growth under stress conditions is provided. The composition for coating plant seeds include glutathione, an amino acid, and an agriculturally acceptable carrier. The glutathione may be oxidized glutathione, and the amino acid may be L-tryptophan. Coated seeds include plant seeds and, on the surface of the seeds, a composition including glutathione and an amino acid.

Abstract: The present invention relates to chitinolytic enzymes, and in particular for a use thereof in plant protection. The invention also relates to a nucleic acid encoding a chitinolytic enzyme a method for producing a chitinolytic enzyme, a plant comprising a chitinolytic enzyme or a nucleic acid encoding the same, a composition of at least one chitinolytic enzyme. The invention relates in particular to the use of a chitinolytic enzyme or a composition comprising the same as a plant protection agent and to a method of protecting plants from pests.

Abstract: The present invention relates to anti-frost proteins, and in particular for a use thereof in plant protection. The invention also relates to a nucleic acid encoding a anti-frost protein a method for producing a anti-frost protein, a plant comprising a anti-frost protein or a nucleic acid encoding the same, a composition of at least one anti-frost protein. The invention relates in particular to the use of an anti-frost protein or a composition comprising the same as a plant protection agent and to a method of protecting plants from pests and/or abiotic stress.

Abstract: The present invention relates to the compositions comprising algae, specifically Spirulina platensis and Chlorella, and their use for the treatment of crops, such as fruits, vegetables and arable crops against heat stress, especially sunburn.
