“Wild olive (O. europaea ssp cuspidata) plants
grow in various regions of Iran and are expected to have considerable genetic diversity due to adaptation to the various environmental conditions. We examined the genetic diversity of four populations of wild olive growing in Hormozgan Province located in southern Iran by using 30 RAPDs and 10 ISSR markers. The mean value of polymorphism for RAPD loci was 73.71%, while the value for ISSR loci was 81.74%. The Keshar population had the highest value of intra-population polymorphism for both RAPD and Emricasan inhibitor ISSR loci (66.86 and 62.71%, respectively), while the Tudar population had the lowest values (20.35 and 28.81%, respectively). Similarly, the highest and lowest number of effective alleles, Shannon index and Nei’s genetic diversity were also found for these two populations. The highest value of H-pop/H-sp within population genetic diversity for RAPD and ISSR loci was ALK inhibitor found for the Keshar population (H-pop = 0.85 and H-sp = 0.90). OPA04-750, OPA13-650 and OPA02-350 RAPD bands were specific for
Tudar, Bondon and Keshar populations, respectively, while no specific ISSR bands were observed. Analysis of molecular variance as well as the pairwise F-ST test showed significant differences for RAPD and ISSR markers among the populations. The NJ and UPGMA trees also separated the wild olive populations from each other, indicating their genetic distinctness. UPGMA clustering of the four wild olive populations placed the Tudar population far from the other populations; Keshar and Bokhoon population samples revealed more similarity and were grouped together. We
conclude that there is high genetic diversity among O. europaea ssp cuspidata populations located in southern Iran. We also found RAPD and ISSR markers 3-deazaneplanocin A to be useful molecular tools to discriminate and evaluate genetic variations in wild olive trees.”
“Chemical doping is one of the major methods by which the properties of BaTiO3 are modified to induce various device characteristics. Doping strategies are generally separated into iso- and aliovalent (donors and acceptors) and into A-and B-site species within the perovskite structure. The A(1g) octahedral breathing mode at similar to 800 cm(-1) in BaTiO3 is Raman inactive for compositions with single B-site species. However, this mode becomes Raman active if more than one B-site species is present, including titanium vacancies, V-T””. Moreover, the relative intensity of the A(1g) breathing mode is qualitatively related to the concentration of the species replacing Ti in the B-site.
