How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Shirin Parizad graduated from the Isfahan University of Technology and completed the Ph.D. from the University of Tehran. The doctoral study was focused on a novel Potyvirus infecting saffron plants (more than 80% incidence), a major commercial crop of Iran. The viral genome was fully characterized and the evolutionary, phylogenetically and biological aspects of this virus were studied. The influence of the novel potyvirus on saffron quality (taste, color, and aroma) was also evaluated. After the doctoral defense, she was associated with Seed and Plant Certification and Registration Institute. Currently, a reviewer in "Iranian Journal of Plant Protection Science (IJPPS) and possess expertise in plant virology, phylogeny, genetic diversity, molecular biology, and bioinformatics.

Saffron latent virus (SaLV) is a species of the genus Potyvirus. The virus has only been reported from saffron (Crocus sativus L.), which is mainly cultivated in Iran, where some other species of Crocus are cultivated as ornamental plants/flowers. The sequence and organization of the SaLV genome has been determined, but there is a lack of informati...
Water is a fundamental necessity for people’s well-being and the ecosystem’s sustainability; however, its toxicity due to agrochemicals usage for food production leads to the deterioration of water quality. The poor water quality diminishes its reusability, thus limiting efficient water usage. Organic farming is one of the best ways that does not o...
The dehydration process is a prerequisite to preserve saffron for a long time. According to this process, saffron shows differences in the main compounds responsible for its quality (colour, taste, aroma, and flavonol content). At present, the freeze-drying method obtains dried products with the highest quality. Viruses can modify the physiology an...
Saffron is appreciated by its colour, taste, and aroma. To examine the effect of abiotic and biotic stress on these main properties, in the span of 2014-2016, saffron stigmas were collected from major different saffron cultivation areas of Iran and saffron quality was estimated. The quality of saffron was assessed by ultraviolet-visible spectroscop...
Saffron (Crocus sativus L., Iridaceae) is one of the most important industrial and export products in Iran. In this study, genetic diversity of new potyvirus Saffron latent virus (SaLV) was investigated based on CP and P1 genomic regions. Following random sampling of saffron plants from Razavi and South Khorasan, Isfahan, Tehran and Fars provinces,...
Saffron (Crocus sativus L.), a highly valuable crop famous for the unique taste, aroma, colour and medicinal properties of the stigmas, is widely cultivated in Iran. During 2011–2016, a total of 965 samples were randomly collected from six important saffron growing provinces of Iran to test for the presence of viruses. Assays revealed the presence...
Maximum likelihood phylogenetic tree based on the complete genome nucleotide sequences of saffron latent virus (bullet) and 36 other potyviruses. The significance of nodes assessed by bootstrap (1,000 replications) is indicated. The sequence of Triticum mosaic virus was used as an outgroup (Parizad et. al., 2018).

Symptoms induced by saffron latent virus (SaLV) in mechanically inoculated test plants: Chlorotic local lesions and systemic leaf distortion on C. amaranticolor (a and b) and C. quinoa (d and e). Mock-inoculated plants (c and f ) did not show any symptoms (Parizad et. al., 2018).
Saffron (Crocus sativus, Iridaceae), a crop widely grown in Iran, was checked in 2011-2015 for the presence of potyviruses collecting a total of 890 leaf tissue samples. DAS- or ACP-ELISA were performed using a Potyvirus genus-specific and other commercial kits (DSMZ, Germany) against 16 different viruses, including three potyviruses, i.e. bean yel...
Following the random sampling of saffron (Crocus sativus L.) leaves and corms from six provinces of Iran, during growing seasons of 2011-2015, a total of 890 leaf tissue samples were investigated by enzyme-linked immunosorbent assay (ELISA) tests. The results revealed that 641 samples showed positive reaction only with Potyvirus genus specific and...
Abstract: Iris belongs to the Iridaceae family. It is one of the most important pharmaceutical and ornamental plants in the world. To assess the potyvirus incidence in natural resources of iris plants in Iran, Antigen Coated-Plate ELISA (ACP-ELISA) was performed on 490 symptomatic rhizomatous iris leaf samples, which detected the potyvirus in 36.7%...
Iris spp. belongs to Iridaceae family, is one of the most important pharmaceutical and ornamental plants in the world. One of the famous groups of Iris belongs to the rhizomatous plants which are used in medical as pharmaceutical plant, in garden as ornamentals and produced commercially as cut flowers. During 2012-2013, a total of 490 of rhizomatou...
I am going to look for Phosphorus Solubilizing Microorganisms, especially Trichoderma viride, Bacillus polymyxa, Bacillus coagulans, Bacillus megaterium, and Streptomyces sp. What are their isolation sources for sampling?
Thanks a lot
What is the reliable and ideal medium (other than Sperber, NBRIP, and PVK media), which can be used for preliminary screening and isolation of potential Phosphorus Solubilizing Gram-positive bacteria?
Thanks a lot
