Low-Cost Strategies for Development of Molecular Markers Linked to Agronomic Traits in<i>Prunus</i>

引用

Agricultural Sciences 2014年第5期5卷 430-439页

作者： Juan A. Salazar Mousa Rasouli Reza Fatahi Moghaddam Zabihollah zamani ali Imani Pedro Martínez-Gómez Department of Horticulture Seed and Plant Improvement Institute Karaj Iran Department of Plant Breeding CEBAS-CSIC Murcia Spain Horticulture Science Department Faculty of Agriculture University of Tehran Karaj Iran

Evaluation of agronomic traits in Prunus breeding programs is a tedious process because of the long juvenile period of trees, the influence of juvenility and the existence of climatic factors affecting the expression of the trait. For these reasons, marker-assisted selection (MAS) strategies are particularly useful in these cases. The objective of this work is the analysis of alternative low- cost strategies for development of molecular markers linked to agronomic traits in Prunus including the application of modified Bulked segregant analysis (BSA) using Simple sequence repeat (SSRs) markers and the application of Random amplified polymorphism microsatellite (RAMP) markers. First BSA results showed that two SSR loci were found to be tightly linked to flowering time in almond. On the other hand, RAMP analysis has been demonstrated to be a potentially valuable molecular marker for the study of genetic relationships in Prunus. Results showed the dominant nature of these markers with a great abundance and transferability although with a reduced polymorphism. In addition, RAMP application in F1 progenies showed its suitability for molecular characterization and mapping, and later Quantitative trait loci (QTL) or BSA analysis.

Results of the Measurement of the Collimator Hole Angulation for Different Collimators of SPECT with Adaptive Quality Control Phantom

引用

Modern Instrumentation 2012年第4期1卷 49-53页

作者： Hossein zamani Zeinali Ehsan Masumi Goodarzi Hamid Ravanbakhsh ali Asgher Sardarpour Narjes Abagheri Mahabadi Soghra Moradkhani Fatemeh Dolatshah Davood Rahi Agricultural Medical and Industrial Research School Nuclear Science and Technology Research Institute Department of Physics Peyambare Azam Institute Islamic Azad University of Tehran

The Adaptive Quality Control Phantom (AQCP) is the computer-controlled phantom which positions and moves a radioactive source in the Field of View (FOV) of an imaging nuclear medicine device on a definite path to produce any spatial distribution of gamma rays to perform the QC Tests such as the Collimator Hole Angulation (CHA) of Single Photon Emission Computer Tomography (SPECT). The collimator hole angulation for seven collimators were measured with the method by using a point source and computer-controlled cylindrical positioning. In this method the displacement of the image of a point source examined as the AQCP move point source vertically away from the collimator face. The results of the high-accuracy measurement method of CHA show that the measurement accuracy for absolute angulation errors is better than ±0.024°. The Root Mean Square (RMS) of CHA for LEHR, LEHS, LEUHR, MEGP-250, MEGP-300, MEGP-360 and HEPH collimators of SMV dual heads camera were measured to be 0.290°, 0.292°, 0.208°, 0.194°, 0.181°, 0.177°, 0.150°, respectively. The Root Mean Square (RMS) of CHA for LEGP, MEGP and HEGP collimators of GE Millennium MG were measured to be 0.154°, 0.220° and 0.202° respectively. It is to be added in this connection that the measured RMS of CHA for LEHR collimator with the distance variation from the collimator’s surface +/– 1 mm has been varied +/– 0.04 degree.
