Rhizobium gone native: unexpected plasmid stability of indigenous Rhizobium leguminosarum.
Lateral transfer of bacterial plasmids is thought to play an important role in microbial evolution and population dynamics. However, this assumption is based primarily on investigations of medically or agriculturally important bacterial species. To explore the role of lateral transfer in the evolution of bacterial systems not under intensive, human-mediated selection, we examined the associatio...
متن کاملCongo Red Absorption by Rhizobium leguminosarum.
Congo red absorption is generally considered a contraindication of Rhizobium. However, R. leguminosarum takes up the dye on yeast extract-mannitol agar. The uptake of congo red varies among strains of R. leguminosarum, as shown elsewhere with strains of R. trifolii and R. meliloti. Congo red absorption does not distinguish rhizobia from other bacteria, but may be useful as a strain marker.
متن کاملبررسی برخی خصوصیات فیزیولوژیک Rhizobium leguminosarum bv. viciae بومی ایران
نیتروژن یکی از مهمترین و پرنیازترین عناصر برای رشد گیاهان است. نیتروژن در کشاورزی، معمولا از طریق کود شیمیایی در اختیار گیاه قرار می‌گیرد که باعث مشکلات زیست محیطی فراوانی می‌شود.. تثبیت زیستی نیتروژن از پدیده‌های طبیعی و استثنایی است که توسط گروهی از باکتری‌ها از جمله ریزوبیوم‌ها انجام می‌شود. باکتری اختصاصی همزیست تثبیت کننده نیتروژن باقلا Rhizobium leguminosarum bv. viciae می‌باشد. یکی از را...
متن کاملEffect of Trichoderma asperellum on growth of Rhizobium leguminosarum in vitro
Trichoderma asperellum has been fronted as a biocontrol agent of root-knot nematodes on tomato and French beans in Kenya. Research on the effect of T. asperellum on growth of Rhizobium species is lacking yet the two interact within the rhizosphere particularly when T. asperellum is applied as a biocontrol agent. Legume roots and Rhizobium species have symbiotic relationship resulting in biologi...
متن کاملSubcellular localization of the nodD gene product in Rhizobium leguminosarum.
In Rhizobium strains the transcription of symbiosis plasmid-localized nod genes, except nodD, is induced by plant flavonoids and requires the nodD gene product. In order to localize NodD protein in R. leguminosarum, a NodD protein-specific antiserum was raised against a lacZ'-'nodD gene fusion product. Using these antibodies, we determined that the NodD protein is located exclusively in the cyt...
