Virology

 

In the Virology / Phytoplasmology section all imported plant material are tested for the presence of foreign viruses, viroids and phytoplasmas.

Diagnostic methods employed include the E nzyme- L inked I mmunosorbent A ssay (ELISA), biological indexing (herbaceous and woody indicators) and Reverse Transcription – Polymerase Chain Reaction (RT-PCR).

Tissue extracts are examined in an electron microscope for the presence of virus-like particles as needed.

PCR assays are used for phytoplasma detection.
