HYPERSENSITIVE RESPONSE ELICITOR PEPTIDES AND USE THEREOF

摘要

Disclosed are hypersensitive-response eliciting peptides that exhibit improved solubility, stability, resistance to chemical degradation, or a combination of these properties. Use of these peptides or fusion polypeptides, or DNA constructs encoding the same, for modulating plant biochemical signaling, imparting disease resistance to plants, enhancing plant growth, imparting tolerance to biotic stress, imparting tolerance and resistance to abiotic stress, imparting desiccation resistance to cuttings removed from ornamental plants, imparting post-harvest disease or post-harvest desiccation resistance to a fruit or vegetable, or enhancing the longevity of fruit or vegetable ripeness are also disclosed.

1. An isolated peptide comprising the amino acid sequence of
(L/I/V/F)-X—X-(L/I/V/F)-(L/I)-X—X-(L/I/V/F)-(L/I/V/A)-X—X-(L/I)-(L/I/V/F) (SEQ ID NO: 93) wherein the peptide is free of cysteine and methionine; each X at positions 2, 6, and 10 is optional and, when present, is any amino acid; and each X at positions 3, 7, and 11 is any amino acid.
