Investigation of Drug Efficacy by Screening Bioactive Chemical Effects on Plant Cell Subcellular Architecture.

New biologically active compounds are regularly discovered through screening procedures using microorganisms. This very cheap procedure is followed by drug discovery that is usually seen as a highly focused approach, testing new compounds on animals or cell lines. In vivo assays of candidate drugs in mammals are expensive and sometimes not affordable at the preliminary stages of drug development. Early screening approaches in transgenic plants would allow chemotherapeutic drug candidates further selection before their characterization in expensive biological models. The proposed screening approach is based on cell subcellular architecture observations in transgenic plants within a short time of treatment, which is better than observing the effects of compounds on growth.
