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 کاملABC Transport Is Inactivated by the PTSNtr under Potassium Limitation in Rhizobium leguminosarum 3841
PTS(Ntr) is a regulatory phosphotransferase system in many bacteria. Mutation of the PTS(Ntr) enzymes causes pleiotropic growth phenotypes, dry colony morphology and a posttranslational inactivation of ABC transporters in Rhizobium leguminosarum 3841. The PTS(Ntr) proteins EI(Ntr) and 2 copies of EIIA(Ntr) have been described previously. Here we identify the intermediate phosphocarrier protein ...
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 کاملGlutathione affects the transport activity of Rhizobium leguminosarum 3841 and is essential for efficient nodulation
As glutathione (GSH) plays an essential role in growth and symbiotic capacity of rhizobia, a glutathione synthetase (gshB) mutant of Rhizobium leguminosarum biovar viciae 3841 (Rlv3841) was characterised. It fails to efficiently utilise various compounds as a sole carbon source, including glucose, succinate, glutamine and histidine, and shows 60%-69% reduction in uptake rates of glucose, succin...
