Determination of vc and mating types of Cryphonectria parasitica isolates by multiplex PCR and their genetic diversity in 13 chestnut-growing provinces of Turkey     

Deniz Çakar  Göksel Özer  Seçil Akıllı Şimşek  Salih Maden 《Forest Pathology》2023,53(3):e12813

Vegetative compatibility (vc) and mating types and genetic diversity of Cryphonectria parasitica isolates were determined using 183 isolates obtained from 215 infected chestnut trees growing in 13 provinces of Turkey. Based on the cultural aspects, 143 of these isolates were evaluated as virulent whereas the remaining 40 isolates were hypovirulent. When vc types of 183 isolates were classically differentiated, 135 of them matched to EU-1 (82.3%), 29 of them to EU-12 (17.6%) vc type, whereas 19 of them did not match to the two. When molecular vic markers were used, all the isolates were assigned to two EU vc types; 149 to EU-1 (81.4%) and 34 (18.5%) to EU-12. Of the majority of the isolates, 134 (73.2%) had mating-type MAT-1, while 44 (24%) isolates had MAT-2 and 5 (2.8%) isolates had both mating types. The population analysis based on two DNA marker systems, Inter-Primer Binding Site and Start Codon Targeted Polymorphism, showed no intraspecific genetic variation among the C. parasitica isolates. The prevalence of two dominant vc types revealed by this study shows that biological control with hypovirulent EU-1 and EU-12 isolates will be significant for the country. The results might be helpful to chestnut breeders carrying out resistance breeding studies to manage this disease based on hypovirulence attributed to Cryphonectria hypovirus 1.  相似文献   

Etude des fongicides utilisés contre la pourriture grise de la vigne au Portugal¹     

par A. FRAZÃO  J.A. ALVES 《EPPO Bulletin》1982,12(2):117-123

La pourriture grise est une maladie très importante au Portugal. On peut affirmer qu'elle cause des dégâts surtout à deux époques: avant la floraison et pendant l'été. C'est dans les régions viticoles du nord du pays qu'on trouve la maladie avant la floraison, provoquant des dégâts de l'ordre de 25 à 30 % de la récolte prévue. A l'exception du sud du pays, toutes les régions viticoles subissent pendant l'été d'importants dégâts qui peuvent atteindre 90 % de la production. Les résultats des essais réalisés pendant 11 ans sont brièvement présentés. Les matières actives suivantes ont été testées: bénomyl, carbendazime, dichlofluanide, dichlozoline, iprodione, méthyldichlofluanide, procymidone, thiabendazole, thiophanate-méthyl, vinchlozo-line, et folpel + oxychlorure de cuivre. Les fongicides les plus recents se sont montrés les plus efficaces. Lorsque le produit est très efficace, la méthode « standard >> ne diffère pas significativement des méthodes consistant à traiter tous les 15 jours ou tous les 8 jours à partir de la floraison (jusqu'à 3 semaines avant la récolte).  相似文献   

TRANSSPLENIC PORTAL SCINTIGRAPHY USING ^99MTC-MEBROFENIN IN NORMAL DOGS     

FEDERICA MORANDI  ROBERT C. COLE  RITA L. ECHANDI  GREGORY B. DANIEL 《Veterinary radiology & ultrasound》2007,48(3):286-291

Transsplenic portal scintigraphy using sodium pertechnetate is superior to per-rectal portal scintigraphy due to improved visualization of the portal vasculature with decreased patient and personnel exposure. The purpose of this study was to describe the use of 99mTc-mebrofenin, the radiopharmaceutical of choice for the evaluation of hepatic function, in place of pertechnetate for transsplenic portal scintigraphy in normal dogs. Sixteen juvenile dogs underwent transsplenic portal scintigraphy using 37-130 MBq 99mTc-mebrofenin in a 0.2-0.5 ml volume. After the initial dynamic acquisition obtained at 4 frames/s in right lateral recumbency, static right lateral, and ventral views were obtained at 5, 10, 15, 20, 25, 30, 40, 50, and 60 min. A nuclear angiogram of the splenic and portal veins was visible in all dogs, followed by rapid distribution of the radiopharmaceutical in the liver. Hepatic morphology was more easily defined than with pertechnetate. Transit time could not be calculated due to the high hepatic extraction of 99mTc-mebrofenin. Mean +/- SD shunt fraction was 0.8 +/- 0.8%. Time to peak liver activity was 3.1 +/- 1.1 min, and hepatic excretion T1/2 was 19.4 +/- 6.3 min. No visible blood pool and cardiac activity was seen after 5 min. The mean +/- SD time to visualization of defined biliary activity was 8.8 +/- 2.9 min. Absorption from the spleen was significantly higher than that reported for pertechnetate (87.9 +/- 8.2%, vs. 52.5 +/- 19.1%). 99mTc-mebrofenin can be used in place of pertechnetate for transsplenic portal scintigraphy, with the advantage of combining quantitative parameters of liver function with the already known advantage of transsplenic portal scintigraphy.  相似文献

Characterization and Purification of Glutathione S-Transferase from the Liver and Gill Tissues of Ağrı Balık Lake Trout Salmo trutta labrax and the Effects of Heavy Metal Ions on Its Activity   总被引：1，自引：0，他引：1  

Veysel Çomaklı  Muslum Kuzu  Ramazan Demirdağ 《Journal of aquatic animal health》2015,27(3):145-151

Glutathione S-transferase (GST) from the liver and gill tissues of A?r? Bal?k Lake Trout (also known as Black Sea Trout) Salmo trutta labrax was characterized and purified, and the toxic effects of some heavy metal ions on the enzyme's activity were analyzed. Liver GST was purified 930 times, resulting in 56% yield using glutathione–agarose affinity chromatography and a specific activity of 60.87 endotoxin units (EU)/mg protein. Using the same procedure, gill GST was purified 576 times, resulting in a 60% yield and specific activity of 46.8 EU/mg protein. The purity check of the purified enzymes was determined with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Optimal pH, ionic strength, and stable pH were found for each tissue, and separate K_M and V_max values were determined for reduced glutathione and 2,4-dinitrochlorobenzene substrates. Heavy metal ions that have toxic effects on living organisms and are known to contribute to environmental pollution were selected, and their in vitro effects on enzyme activity were analyzed. The IC50 values and K_i constants of those metal ions showing an inhibitory effect on GST activity were determined.

Effects of dietary boron and phytase supplementation on growth performance and mineral profile of broiler chickens fed on diets adequate or deficient in calcium and phosphorus     

M. Çinar  K. Küçükyilmaz  A. U. Çatli  E. Bintaş  H. Akşit 《British poultry science》2015,56(5):576-589

1. Two experiments were designed to determine the effect of dietary boron (B) in broiler chickens. In Experiment 1, a 2 × 4 factorial arrangement of treatments was used to investigate the effect of dietary calcium (Ca) and available phosphorus (aP) (adequate or deficient) and supplemental B (0, 20, 40, and 60 mg/kg diet). In Experiment 2, B, at 20 mg/kg, and phytase (PHY) (500 FTU/kg diet) were incorporated into a basal diet deficient in Ca and aP, either alone or in combination.

2. The parameters that were measured were growth performance indices, serum biochemical activity as well as ash and mineral (i.e. Ca, P, Mg, Fe, Cu and Zn) content of tibia, breast muscle and liver.

3. Results indicated that both supplemental B and dietary Ca and aP had marginal effects on performance indices of chickens grown for 42 d.

4. There were positive correlations (linear effect) between B concentrations of serum, bone, breast muscle and liver and the amount of B consumed.

5. Serum T₃ and T₄ activities increased linearly with higher B supplementation.

6. Increasing supplemental B had significant implications on breast muscle and liver mineral composition. Lowering dietary Ca and aP level increased Cu content in liver and both Fe and Zn retention in breast muscle. Tibia ash content and mineral composition did not respond to dietary modifications with either Ca–aP or B.

7. The results also suggested that dietary contents of Ca and aP do not affect the response to B regarding tissue mineral profile. Dietary combination with B and PHY did not create a synergism with regard to growth performance and bioavailability of the minerals.  相似文献   

Anatomical Structure of the Brachial Plexus in the Merlin (Falco columbarius)     

A. Çevik‐Demirkan 《Anatomia, histologia, embryologia》2014,43(1):31-35

This study aimed to document the detailed features of the morphological structure and the innervation areas of the brachial plexus in Merlin (Falco columbarius). The skin and muscles of five adult male Merlins were dissected under the stereo microscope. The Merlin had two plexus trunks. The accessory brachial plexus consisted of ventral rami C10 and C11. C11 was divided into two branches: the cranial and caudal. The brachial plexus was composed of a rather complex network involving the ventral rami of C11‐C13, T1 and T2. In addition, a thin branch from the last two cervical sympathetic nerves participated in the plexus formation. C12, C13 and T1 had rather thick trunk. C12, C13 and T1 were also involved in the formation of the brachial plexus emerging after 1 cm from the foramen inter‐vertebrale as three trunk roots.  相似文献
