In addition to its ability to protect plants against diseases, Harpin protein also reduces infestations of selected insects and enhances plant growth, general vigor, and yield of many crops, including vegetables, traditional agronomic crops and ornamentals.
Harpin protein initiates a complex set of metabolic responses in the treated plant, causing natural gene expression and eliciting a plant’s natural defense and growth systems. It is isolated from Erwinia amylovora, the bacterial pathogen that causes the disease fire blight in apples and pears.

EPA approves use of Cornell-discovered protein that enables …
Apr 27, 2000 · The U.S. Environmental Protection Agency has granted conditional registration for the first commercial agricultural use of harpin, a Cornell-discovered protein that induces a plant to mobilize its own defenses against pathogens and insects. …
cellular space of plant tissues, unlike bacterial effector proteins that act inside the plant cells. Over the two decades since the first harpin of pathogen origin, HrpN of Erwinia amylovora, was reported in 1992 as a cell-free .
Harpin Hpa1 Interacts with Aquaporin PIP1;4 to Promote the ... - Nature
Nov 26, 2015 · Our findings demonstrate the first case that plant sensing of a bacterial harpin protein is connected with photosynthetic physiology to regulate plant growth.
HrpZ Family - Wikipedia
HrpZ - a harpin - is a highly thermostable protein that exhibits multifunctional abilities, e.g., it elicits the hypersensitive response (HR), enhances plant growth, acts as a virulence factor, and forms pores in plant plasma membranes as well as artificial membranes. [2]
Harpins, multifunctional proteins secreted by gram-negative plant ...
Harpins are glycine-rich and heat-stable proteins that are secreted through type III secretion system in gram-negative plant-pathogenic bacteria. Many studies show that these proteins are mostly targeted to the extracellular space of plant tissues, unlike bacterial effector proteins that act inside the plant cells.
Harpin αβ protein is a harpin-based active ingredient similar in chemical structure and biological activity to Harpin protein (Messenger®) registered in April, 2000. It acts by initiating a complex defense mechanism in plants, analogous in some ways to …
