Study of telomerase activity in sunflower infected by sclerotinia fungus
Maryam Parvini and Erfan Jamshidi
Islamic Azad University, Iran
Root and crown rot caused by necrotrophic fungal pathogen
Sclerotinia sclerotiorum (Lib.) de Bary is one of the most
important diseases, infects over 400 plant species, include
sunflower. Telomerase activity is highly regulated, abundant
in animal rapidly dividing cells and reproductive organs. It has
been demonstrated that this enzyme may be related to in
aging process and cancer. However, evidence for a correlation
between telomerase activity and diseases across plant groups
is weak. In this study for the first time the relationship between
sclerotinia rot and telomerase activity was investigated. We
hypothesized that the rate of TERT expression could confer
tolerance against this fungal pathogen. To test this hypothesis,
susceptible (SDR19) and resistant (LC1064-C) genotypes of
sunflower infected with the A37 fungal isolate. Experimental
samples were taken from the leaves of Helianthus annus and
evaluated by real time PCR. The results indicated the reduction
of TERT expression in both susceptible and resistant strains
under fungal disease stress. These results also showed the
higher expression in resistant line than the sensitive one. This
difference may be correlated with the expression of resistance
genes in the resistant line, which need more investigation.
Speaker Biography
Maryam Parvini has completed her PhD at the age of 31 years from Islamic azad
University, science and research branch, Tehran, Iran. After 3 years research in
Royan institute (for my Ph.D thesis), whose ranking is the first for stem cells and
Developmental biology researches in Iran, She achieved a thorough understanding of
every aspect of these areas, especially neural patterning and achieving the different
neural progenies from human embryonic stem cells. Her most recent position as
scientific staff in Islamic Azad University,Urmia, Iran, has provided me with 1 year
supervisory experience as leader of students. She is also keen to express my
deep interest to Plant science, especially for molecular aspects. It was extreem and
enough cause to bigen my cooperation with Prof. Dr Reza Darvishzadeh, who is plant
biotechnologist. Since this field obviously take a great leap forward, she need to go
on with learning and experiencing as to assist me in this feild more and more. She is a
reviewer of some Iranian journals.
