Astragalus unalii Cecen, Aytac and Mısırdalı, sp. nov. (Fabaceae, sect. Malacothrix Bunge) is described as a new species from Karadağ (Karaman Province) in southern Anatolia and compared with its relatives growing in steppe vegetation. The new species is close to A. tauricola Boiss. and A. adiyamanensis Podlech & M.Ekici, endemic and growing in central and southern parts of Anatolia, Turkey. Taxonomic descriptions, pollen and seed characters, and geographical distribution of the new species are presented. © TÜBİTAK. Source

The production cross sections σ K i, the fluorescence yield W K, K shell X-ray intensity ratio I K β / I K α, the vacancy transfer probabilities from K to L shell η K L, and the Γ K level widths for some elements in the atomic range 40 ≤ Z ≤ 50 were measured. The samples were excited by 80.998 keV gamma rays from a 10 mCi 133Ba radioactive source. The K X-rays emitted by samples were detected by using a CdTe detector. These parameters have been theoretically calculated, also. The experimental values were compared with the theoretical and semiempirical values. Our experimental values closely agreed with theoretical values and other experimental values. © 2013 Pinar Onder et al. Source


Objective: The objective of the study was to examine the nutritive value of Helix lucorum meat and to create awareness about fatty acid composition of phospholipid subclasses of the total body and cephalopedal tissues of the snail. Methods: Thin layer chromatography plates contained lipid samples placed in the chromatography tank containing: chloroform/ethanol/water/triethylamine. The phospholipid subclasses were dissolved in about 5 ml of methanol and 5 drop of sulfuric acid. The mixture was refluxed for 2 h to form fatty acid methyl esters at 85 °C. Fatty acids were detected by Gas chromatography. Results: The most noteworthy result was the high level of C20:2ω6 in PE (10.49%-11.35%) and PC (17.33%-12.96%). Appreciable quantity of essential fatty acid C18:2ω6 was determined in PC (20.85%-17.46%) and PE (16.88%-17.53%) from both tissues. Precursor of eicosanoids, C20:4ω6 was found apparently high in PI, PS and PE of the total body. The highest level of ΣPUFA was 63.90% in PE from total body whereas the highest level of ΣSFA was 60.79% in PI from the cephalopedal. ΣMUFA level was pretty low in PI, PS and PE. Conclusion: The study is a guide for biochemical and nutritional value of edible snails and can be useful for further investigation on physiological and systematic studies of other species. © TurkJBiochem.com.

The purpose of this study was to characterize olive core collection with amplified fragment length polymorphism (AFLP) markers and fruit traits and to determine AFLP markers significantly associated with these fruit characters in olive. A total of 168 polymorphic AFLP markers generated by five primer combinations and nine fruit traits were used to characterize relationships between 18 olive cultivars. Although all olive cultivars were discriminated from each other by either AFLP markers (<0.75 similarity level) or fruit traits, clustering based on the AFLP markers and fruit traits was not significantly correlated (r = 0.13). Partial clustering of olive cultivars by AFLP markers according to their geographical origin was observed. Associations of AFLP markers with fruits were determined using a multiple-regression analysis with stepwise addition of AFLP markers. Significant associations between eight AFLP markers and fruit traits were identified. While five AFLP markers demonstrated significant negative correlation with fruit and stone weight, width and length and total polyphenols (P < 0.05), three AFLP markers displayed significant positive correlation with α-tocopherol and γ-tocopherol (P < 0.01). This is the first report on the association of molecular markers with fruit traits in olive. Molecular markers associated with morphological and agronomic traits could be utilized for the breeding of olive cultivars. However, the association power of these markers needs to be confirmed in larger populations, and highly correlated markers should then be converted to PCR-based DNA markers such as sequence-characterized amplified region markers for better utilization. © FUNPEC-RP.

The purpose of this research was to characterize an olive core collection using some agronomic characters and simple sequence repeat (SSR) markers and to determine SSR markers associated with the content of fatty acids in olive oil. SSR marker analysis demonstrated the presence of a high amount of genetic variation between the olive cultivars analyzed. A UPGMA dendrogram demonstrated that olive cultivars did not cluster on the basis of their geographic origin. Fatty acid components of olive oil in these cultivars were determined. The results also showed that there was a great amount of variation between the olive cultivars in terms of fatty acid composition. For example, oleic acid content ranged from 57.76 to 76.9% with standard deviation of 5.10%. Significant correlations between fatty acids of olive oil were observed. For instance, a very high negative correlation (-0.812) between oleic and linoleic acids was detected. A structured association analysis between the content of fatty acids in olive oil and SSR markers was performed. STRUCTURE analysis assigned olive cultivars to two gene pools (K = 2). Assignment of olive cultivars to these gene pools was not based on geographical origin. Association between fatty acid traits and SSR markers was evaluated using the general linear model of TASSEL. Significant associations were determined between five SSR markers and stearic, oleic, linoleic, and linolenic acids of olive oil. Very high associations (P < 0.001) between ssrOeUA-DCA14 and stearic acid and between GAPU71B and oleic acid indicated that these markers could be used for marker-assisted selection in olive. © FUNPEC-RP.
