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