Seed yields and biochemical compounds of common vetch (vicia sativa L.) lines grown in semi-arid regions of Turkey

Common vetch (Vicia sativa L.) is used for grain, hay or green manure in the semi-arid regions of Turkey. The objective of this study was to determine the seed yields and biochemical compounds of seeds for common vetch lines grown under rain-fed conditions in semi-arid regions of Turkey. Four common vetch lines (845, 2640, 1448 and 384) were obtained from the international center for agricultural research in dry areas (ICARDA). Field experiments were designed according to randomized block design with three replications during 2004/05 and 2005/06. Seed yields, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), crude fat (CF) and amino acid (aa) contents of common vetch lines were determined. Seed yields ranged from 1160 - 1459 kg.ha-1, CP content ranged from 24.94 - 27.86%, ADF content ranged from 5.81 - 8.45%, NDF ranged from 9.89 - 11.42% and CF content ranged from 1.16 - 3.23% based on the averages of the two years results.Key words: Common vetch, crude protein content, acid detergent fiber content, amino acid

Comparison of α, β and total ODAP (β-N-oxalyl-L-ά,β- diamino propionic acid) contents in winter- and springsown grasspea (Lathyrus sativus L.) genotypes

There is a strong relationship between the consumption of grasspea (Lathyrus sativus L.) and “lathyrism” disease caused by a neurotoxin, β-N-oxalyl-L-a,β-diaminopropionoc acid called ODAP or BOAA. The objective of this study was to compare α, β and total ODAP found in grasspea genotypes sown in winter and spring seasons during 2007/08 and grown under rainy conditions in semi-arid regions of Turkey. Biochemical compounds of α, β and total ODAP were found to be higher in springsown grass peas than those of winter-sown ones. Grasspea 452, 508 and 519 genotypes had lower β- ODAP levels in winter- and spring-sown.Key words: Grasspea, α-ODAP, β-ODAP: 3-(-N-oxalyl)-L-2,3-diamino propionic acid

Analysis of the common genetic component of large-vessel vasculitides through a meta- Immunochip strategy

Giant cell arteritis (GCA) and Takayasu's arteritis (TAK) are major forms of large-vessel vasculitis (LVV) that share clinical features. To evaluate their genetic similarities, we analysed Immunochip genotyping data from 1,434 LVV patients and 3,814 unaffected controls. Genetic pleiotropy was also estimated. The HLA region harboured the main disease-specific associations. GCA was mostly associated with class II genes (HLA-DRB1/HLA-DQA1) whereas TAK was mostly associated with class I genes (HLA-B/MICA). Both the statistical significance and effect size of the HLA signals were considerably reduced in the cross-disease meta-analysis in comparison with the analysis of GCA and TAK separately. Consequently, no significant genetic correlation between these two diseases was observed when HLA variants were tested. Outside the HLA region, only one polymorphism located nearby the IL12B gene surpassed the study-wide significance threshold in the meta-analysis of the discovery datasets (rs755374, P?=?7.54E-07; ORGCA?=?1.19, ORTAK?=?1.50). This marker was confirmed as novel GCA risk factor using four additional cohorts (PGCA?=?5.52E-04, ORGCA?=?1.16). Taken together, our results provide evidence of strong genetic differences between GCA and TAK in the HLA. Outside this region, common susceptibility factors were suggested, especially within the IL12B locus

THE EFFECT OF FERTILIZATION AND GRAZING APPLICATIONS ON ROOT LENGTH AND ROOT BIOMASS OF SOME RANGELAND GRASSES

WOS: 000355062000006It is important to know the effects of applications such as fertilization and grazing on the vegetation improvement of certain species. This study was conducted to examine the effect of grassland improvement by fertilization and grazing on root length and biomass of various grassland grasses (Festuca ovina L., Koeleria cristata (L.) Bertol, Chrysopogon gryllus (L.) Trin., Bothriochloa ischaemum L. Keng) of the Tokat province of Turkey in the years 2008 and 2009. Great variations were observed among grass species in all applications. All different fertilization and ungrazed applications increased root length and root biomass parameters. Root lengths and root biomass of the species varied from 8.16 to14.27 cm and from 0.73 to 4.73 g, respectively. The longest root lengths and root biomass results were obtained from ungrazed land+ 75 kg ha(-1) N+P2O5 fertilization application

THE FACTORS AFFECTING YIELD AND QUALITY OF HUNGARIAN VETCH plus CEREAL MIXTURES IN ARID ENVIRONMENTAL CONDITIONS

WOS: 000455562500043This study was carried out to determine the performances of pure sowing of Hungarian vetch (HV) (Vicia pannonica Crantz), barley (Hordeum vulgare L.), triticale (T) (XTriticosecale Wittmack) and their mixtures with HV in arid conditions during 20122013 and 2013-2014 vegetation seasons. The experiment was designed based on split plots in a randomized block design with four replicates. Three different cutting times of pure sowing and mixtures were determined as booting, flowering and milk dough stages. Vetches were at 10% flowering when cereals were in booting stage, the vetches were in full flowering while the cereals were in flowering stage, while the lower pod-setting of vetches, the cereals were in milking dough stage. The pure sowing vetch was also harvested during these periods. The highest wet and dry hay yields, considering the mixture and cutting time separately, were obtained at the milk dough stage from the mixture of 25% HV + 75% T. The crude protein ratio increased with the increase in HV ratio of mixtures while the ratios of ADF and NDF decreased. The extend of cutting time from booting to milk dough stage increased the hay yield while quality traits were decreased. The superior yield and quality traits of annual legume + cereal mixtures, when evaluated along with cutting time, suggested that harvesting of 50% HV+50% T mixture can be recommended during flowering period.Gaziosmanpasa University Scientific Research Projects Coordination Unit [2013/75]This manuscript was produced from PhD thesis funded by Gaziosmanpasa University Scientific Research Projects Coordination Unit with project number of 2013/75

Leptin Gene Polymorphisms in Native Turkish Cattle Breeds

The aim of the study was to determine leptin gene polymorphisms in South Anatolian Red (SAR), East Anatolian Red (EAR) and Turkish Grey Cattle. In the study unrelated 40 SAR. 40 EAR and 40 Turkish Grey cattle were used. Target sites in leptin gene exon 2, exon 3 and intron 2 were amplified by polymerase chain reaction (PCR). The single nucleotide polymorphism (SNP) consisting site in exon 2, exon 3 and intron 2 were determined as a result of digestion with Kpn2l. HphI and Sau3Al restriction enzymes, respectively. The highest T allele frequency related with production traits for Kpn2l polymorphism was found for SAR cattle. For HphI polymorphism. T allele frequencies were detected clearly predominant. Within each breed for Sau3Al polymorphism B and C allele frequencies that effect production traits were found to be dramatically lower than A allele frequency. As a result we can suggest that there was no clearly difference that can create any advantage in terms of leptin gene SNPs among the three native Turkish cattle breeds
