    Problem Definition: Among the schools of miniature paintings, those paintings left from the Shiraz school of the eighth century AH are significant and unique due to the preservation of the artistic traditions of ancient Iran and their expressive approach. Considering that the composition of the paintings based on the arrangement of the figures was one of the main features of the Shiraz school of miniature painting in the Al-Inju period, this study aimed to study and compare the method of characterization in the paintings of two illustrated manuscripts left from the Shiraz school, namely Samak-e Ayyār with 80 images and the Shāhnāmeh 733 AH with 52 images. In addition, it provides explanations about the characterization and design of the figures in Al-Inju miniature paintings and addresses the similarities and differences between the images of these two illustrated manuscripts.Objective: The present study aimed to identify and investigate the characterization of the Shiraz school of miniature painting through the visual analysis of the two illustrated manuscripts of Shāhnāmeh 733 (St. Petersburg) and Samak-e Ayyār (Oxford).Research Method: This research is qualitative in terms of the nature of data and is fundamental considering the purpose. Data collection is a library-based approach, and various instruments such as observation and checklist have been used in compiling the data and writing the research results.Results: The characters in the studied paintings can be divided into six groups based on their social status: kings, court women, non-court women, female Ayyār, servants, and warriors. The results of this study indicate that each of these six groups differs in following the visual conventions in terms of the type of costume and their physical placement mode in the paintings; the style and position of the characters in the two versions of paintings show their personality traits and social status in each story. In this way, the appearance and design of human characters are the same in both manuscripts, but the way the painter deals with the characters in each version is different. The painter of the Samak-e Ayyār illustrated manuscript has provided more painting space for high-ranking characters, including kings. He portrayed kings, both good and evil, sitting on thrones while the painter of Shāhnāmeh 733 AH manuscript has considered the throne as a place to show royal oppression; the kings were not depicted seated on the throne in Shāhnāmeh manuscript unless they were on the side of evil

    PubMed ID: 22413768Trifluralin is a widely used dinitroaniline herbicide throughout the world. However, limited efforts have been made to study its genotoxic effects on different plants. The present study aimed to evaluate the herbicide's genotoxic potential on maize (Zea mays) by using the random amplified polymorphic DNA (RAPD) technique. For this purpose, maize seedlings were treated with aqueous solutions of trifluralin at concentrations ranging from 0.5 to 3 ppm for 7 days. In the RAPD analyses, 15 primers were used and 91 bands were obtained, with an average of 6.06 bands per primer in the control seedlings. After trifluralin treatment, significant changes were observed in RAPD profiles. These changes included loss of normal bands and appearance of new bands, in comparison to the control group, and they were dose dependent. In addition, root growth and total soluble protein level in trifluralin-treated seedlings were analyzed and compared for genomic template stability (GTS), which was performed for the qualitative measurement of changes in randomly amplified polymorphic DNA (RAPD) profiles. The results showed that GTS, root growth, and total soluble protein content of the seedlings gradually decreased with an increase in trifluralin concentration. These findings suggest that the RAPD technique is a useful biomarker assay to evaluate the genotoxic effects of herbicides on plants. © 2013 Informa Healthcare USA, Inc

    WOS: 000441461100002Plants use in many fields has increased significantly with the increasing of biotechnological methods from past to present. Their secondary metabolites are commonly used in many fields from medicine to agriculture. Because of their easy degradation, they will be used as an alternative to the synthetic chemicals. Deciding their proper non-phytotoxic doses for cereals will secure their safe usage. The present study aimed to determine the potential biopesticide activity of plants natural components in weeds. Thus, the essential oils obtained from Satureja hortensis species of Lamiaceae family were subjected to analysis of volatiles and applied to Hordeum vulgare L. seedlings. Potential genotoxic effects of these components on the seedlings were determined by RAPD (Randomly Amplified Polymorphic DNA) PCR. The oils were applied in four different doses (0.2, 0.4, 0.8 and 1.6 mu L mL(-)(1)). Results indicated that the third (0.4 mu L mL(-)(1)) dose has changed the genomic stability about 46.16 % and remaining doses changed the genomic stability over the 50 %. The effects of the essential oils on root and stem length of barley seedlings were varied. The oils have increased the root length and inhibited stem length in all doses compared to the control. It was concluded that plant essential oil components showed similar effects of synthetic chemicals in the literature. With the exception of the 0.4 mu L mL(-)(1), which may be phytotoxic in Hordeum vulgare L. seeds, all doses tested in the study have the potential to be used as bio pesticides against weeds
