Abstract/OtherAbstract:
We examined the tissue distribution, synthesis stage, and ethylene induction of three types of pineapple chitinase using chitinase activity gel and immunoblot analysis. Type A (acidic class III) exists in all tissues, while type B (weakly basic class I, which has strong antifungal activity) and type C (acidic class I) are localized mainly in the leaf and stem. In a pericarp, type A exists at all stages during fruit development, while type B and type C exist only at the early stage. Synthesis of type A is induced by ethylene, while that of types B and C is not affected by it. These results suggest that the physiological roles of these three types of chitinase in pineapple are different.
