A chitinase activity was detected in fractions of xylem sap collected from the cut surface of cucumber stems. A 28-kDa acidic protein was purified from the active fractions and its N-terminal amino acid sequence was found to be identical to that of a chitinase gene. Cucumber roots produce and secrete an acidic chitinase, one of the PR proteins, into xylem sap and deliver it to aboveground organs.
