A Leaf-specific 27 kDa Protein of Potato Kunitz-Type Proteinase Inhibitor Is Induced in Response to Abscisic Acid, Ethylene, Methyl Jasmonate, and Water Deficit

Year: 2002

Type: article

Abstract: The 22 kDa Kunitz-type potato proteinase inhibitor (22 kDa KPPI) was induced in tubers. However, the 27 kDa protein, which is immunologically related to the 22 kDa KPPI, was induced in leaves by wounding, hormones, and environmental stresses. The leaf-specific 27 kDa protein was induced in leaves that were treated with exogenous abscisic acid (ABA), ethephon, methyl jasmonate (MeJA), and water deficit. These results indicate that the 27 kDa protein in leaves could function as a defense protein against mechanical damages by herbivorous animals and abiotic environmental stresses that could induce plant hormones.
