摘要: The objective of the present paper was to investigate reason increased tolerance pathogenic fungus Pseudoperonospora cubensis found in transgenic cucumber (Cucumis sativus L.) lines 210 and 212 bearing 35S:cDNA preprothaumatin II gene construct. investigation accomplished by comparing morphological anatomical structure plant leaves. results obtained demonstrate that leaves both exhibited some characteristics (e.g. wax load composition, cuticle ultrastructure, ultrastructure secondary wall, arrangement mesophylll cells) which may be responsible for enhanced tolerance.
