Plant Virology Research Center (PVRC)


History and Justification

Plant viruses as a group are capable of inflicting heavy losses to agricultural crops and in this respect they are second only to fungi. In Iran, annual losses by some of these viruses are tremendous. Complete loss of wheat crop by wheat streak mosaic virus, devastation of maize plantations by maize rough dwarf virus, destruction of sugar beet fields by rhizomania, and severe reduction of wheat yield by barley yellow dwarf viruses are some of the notorious examples of heavy loss by viruses. Iranian maize mosaic virus and potyviruses in maize, tristeza virus in citrus, tomato leaf curl viruses in tomato, curly top viruses in sugarbeet, zucchini yellow mosaic, watermelon chlorotic sunt, cucurbit yellow stunting disorder, and tomato leaf curl Palampour viruses in cucurbits, barley yellow striate mosaic virus in wheat and black gall dwarf in rice are some other causes of concern in various regions of the country. Witches' broom phytoplasma (a virus-like agent) is currently at large in southern provinces, destroying lime trees by hectares and threatening annihilation of the total lime industry in this region. Spiroplasma citri and Liberibacter asiticus have been taking toll of our citrus industry for many years.


The economic and scientific importance of viruses and phytoplasmas and their requirement of specialized and somewhat sophisticated research on one hand, and research precedence and potency in the College of Agriculture, Shiraz University on the other, led the Ministry of Agriculture to approve and finance the establishment of a center for advanced studies on viruses (especially those of cereal crops) in that College. The project began in 1993 and the center became operative in 1998. This in turn prompted augmentation of research on plant viruses.

 Based on evaluation of research and extension activities and other qualifications , PVRC was designated "Center of Excellence in Plant Virology" by the "Council of Centers of Excellence" in 2002. Later it was named "Outstanding Center of Excellence" in 2007.


PVRC has provided infrastructure for various types of research on plant viruses and phytoplasmas. It is a ca. 2800-square meter facility including laboratories, greenhouses, classroom, and offices. Laboratory equipments include facilities for virus purification and characterization, molecular studies, biology and serology of viruses and phytoplasmas, tissue culture, DNA cloning, gene transfer, proteomics, etc.



PVRC Goals

1. Specialized research (basic and applied) on viruses of agricultural plants.

2. Promotion of plant virological research.

3. Conducting "ordered" research to meet the demands and solve the problems of ordering


4. Establishing nationwide contact among plant virologists and phytoplasmalogists.

5. Promotion of plant virology education.

6. Promotion of international cooperation and scientific exchange.

7. Supporting other institutes and laboratories in conducting research on plant viruses and
