White flagging of alfalfa, Medicago sativa 'Ranger, found associated with Ditylenchus dipsaci in the Columbia River Basin was observed in northern Utah during 1971. This is a report on chloroplast changes, induced by D. dipsaci in alfalfa leaves, as observed with an electron microscope. Leaves from alfalfa plants infected with D. dipsaci were either devoid of normal pigmentation or displayed va...

In this study, we aimed to determine the nematode diversity in soils from olive orchards İzmir, Manisa, Çanakkale, and Balıkesir provinces. For purpose, a survey was carried out 2021-2022; each orchard, soil samples were collected 0-60 cm depth, nematodes extracted by modified Baermann Funnel method. Thirty-seven genera of (Achromodora, Acrobeles, Acrobeloides, Alaimus, Aphelenchus, Aphelenchoi...

Experiments were conducted to determine the effects of plant confinement, soil type, watering practices, stage of seed germination, inoculum level, and method of applying inoculum on stem nematode (Ditylenchus dipsaci) infection of alfalfa (Medicago sativa) seedlings grown in soil. Results indicated that (i) confining seedlings together with the nematodes in small vials offered no advantage ove...

spective haptenic sugars prevented their adsorption by the gelatinous nlatrix or the egg shells, whereas incubation with sugars other than the correct hapten inhibitor did not interfere with binding of the lectins. These last findings lend support to the idea that the described lectin-binding pat tern was not a result of nonspecific adsorption or uptake by the gelatinous matr ix or the egg shel...

چکیده به منظور بررسی تنوع زیستی نماتدهای انگل گیاهی مزارع یونجه شهرستان اهر و با توجه به نبود تحقیقات جامع در مورد نماتدهای انگل گیاهی مزارع یونجه و لزوم شناسایی عوامل مهم کاهش کمی و کیفی این محصول در این منطقه تحقیق مورد نظر صورت گرفت.  با جمع آوری33 نمونه خاک ازمزارع یونجه مناطق مختلف شهرستان اهر طی سالهای 1382 و1383، بخشی ازتنوع زیستی نماتدهای انگل گیاهی این محصول شناسایی گردید. دراین تحقیق،...

The potato rot nematode, Ditylenchus destructor, is a very destructive nematode pest on many agriculturally important crops worldwide, but the molecular characterization of its parasitism of plant has been limited. The effectors involved in nematode parasitism of plant for several sedentary endo-parasitic nematodes such as Heterodera glycines, Globodera rostochiensis and Meloidogyne incognita h...
