Abstract:
Cucumber (Cucumis sativus L.) is considered a model plant for the investigation of Fe deficiency responses, since it strongly exhibits typical strategy I, i. e. increased activities of Fe(III)-chelate reductase, H +-ATPase and iron regulated transporters. In this study, cDNA amplified fragment length polymorphism analysis was employed to identify genes differentially expressed in the root apex following Fe deficiency. The expression patterns of the most interesting transcript derived fragments were validated by semiquantitative reverse trascriptase - polymerase chain reaction. A set of new genes overexpressed under Fe deficiency, such as those coding for calmodulin, SNAP, TIM23 and V-PPase were identified. Furthermore, we also observed that calmodulin protein accumulated in Fe-deficient root apexes.
