Application of SSR Markers for Characterization of Genetic Diversity within Iranian Grapevine Cultivars ('Askari' and ;Keshmeshi')
No full textThe present study was designed to identify intra-varietal diversity via SSR markers within `Askari' and `Keshmeshi' (Vitis vinifera L.). These two semi-seedless grape cultivars are used as table grape and raisin. Some accessions of these cultivars are morphologically different. For instance, some accessions had big berries with big bunches and empty seeds, whereas others had small berries in small bunches with soft seed traces. In order to evaluate these differences at the genetic level, we selected 14 SSR loci to evaluate intra-cultivar diversity. In total, 42 accessions of 'Askari', 10 accessions of 'Keshmeshi' and one accession of Sultanina as a control were analysed, using a capillary electrophoresis fragment sizing system. Genetic analysis discriminated six accessions of `Askari' (No. A3, A21, A31, A44, A46, and A114) which were different from other accessions. These accessions were also different in some morphological traits. Accessions no. A3 and no. A21 had soft seed traces with berries and bunches that were smaller than others. Other accessions had empty seeds. Accessions no. A44, A46 and A114 had big bunches, big berries and empty seeds. In accession no. A31 berry shape was approximately round vs. oval shape in other accessions. The remaining accessions (36 accessions) were identical in 14 SSR loci. In 'Keshmeshi' four different accessions (No. K6, K8, K15, and K27) were discriminated in genetic analysis. In accessions no. K6 and no. K8, the number of bunch and yield per vine was higher than other accessions. In accessions no. K15 and no. K27, berries and bunches were bigger than others and the number of seed traces were higher than other accessions. Other six accessions were identical in14 SSR loci. Cluster analysis of all three cultivars divided accessions to three groups (each cultivar in one group) at 0.67 similarity coefficient. Our study showed SSR markers can be useful for identifying of intra-cultivar diversity
Clonal Selection within Grapevine 'Askari' by Molecular Markers
No full textGrapevine 'Askari' is one of the important seedless table grapes in Iran. In spite of its asexual propagation, morphological markers determined differences in some accessions of this cultivar, e. g., some accessions have hard empty seeds. However, others have soft seed traces. Some of these morphological factors are useful for economical value and breeding programs. In order to evaluate these differences in genetical level, this project was designed to identify genetic variability via SSR markers within accessions named as 'Askari' cultivar. In this study 42 accessions were selected and collected from different provinces of Iran. 8 highly polymorphic SSR primers (VVS2, VVMD7, VVMD14, VVMD25, VVMD27, VVMD36, vrZAG47 and vrZAG79) were used to compare accessions. Three loci (VVS2, VVMD36 and vrZAG79) showed polymorphism. The overall results of the SSR analysis detected 5 accessions (no. 21, 31, 44, 46 and 114) which were different from others. The present study confirmed, SSR markers can be useful for identifying intra-cultivar diversity. This work requires more study to define the relation between genetical differences and some important morphological traits

NiO–Co3O4–rGO as a Multicomponent Transition Metal Oxide Nanocatalyst for Ultra‐level Detection of Nitrite in Beef and Tap Water Samples
No full textThe detection of nitrite as a challenging compound in food industries has always been a necessity. To this purpose, herein, two transition metal oxide-based nanocatalysts, NiO–Co3O4 (NC) and its reduced graphene hybridized form, NiO–Co3O4–rGO (NCR), are synthesized by a hydrothermal method and characterized by X-ray diffraction, Raman spectroscopy, scanning electron microscope (SEM) images, and energy dispersive X-ray analysis (EDAX) mapping. The synthesized materials are exploited to modify a glassy carbon electrode and fabricate an effective sensor for nitrite detection in real samples through differential pulse voltammetry (DPV). NCR shows excellent sensitivity (40.44 μA per dec), very low limit of detection (20 × 10-9 m), significant accuracy, and good stability at the wide range of nitrite ions (100–500 × 10-9 m) in real sample
Design and comparative techno-economic analysis of two solar polygeneration systems applied for electricity, cooling and fresh water production
No full textTwo solar polygeneration systems were investigated for electricity, cooling and fresh water production. In the first scenario (LFPS), the linear Fresnel (LF) solar field was used as thermal source of the Organic Rankine Cycle (ORC), absorption chiller (ACH) and multi-effect desalination (MED) unit. In the second scenario (PVPS), photovoltaic (PV) panels were considered as the electricity source to supply the electricity load that is required for lighting, electrical devices, compression chiller (CCH) and reverse osmosis (RO) units. A techno-economic comparison was made between two scenarios based on the land use factor (F), capacity utilization factor (CUF), payback period, levelized cost of electricity (LCE), levelized cost of cooling energy (LCC) and levelized cost of water (LCW). The calculations were conducted for four different locations in order to determine the effect of solar radiation level on the LCE, LCC and LCW of systems in both scenarios. The results showed that the LCE and LCW of PVPS is lower than that of LFPS and the LCC of LFPS is lower than that of PVPS. Also, the payback period of LFPS and PVPS systems are obtained as 13.97 years and 13.54 years, respectively, if no incentive is considered for the electricity sale
