بررسی 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 کاملRegulation of L-alanine dehydrogenase in Rhizobium leguminosarum bv. viciae and its role in pea nodules.
Alanine dehydrogenase (AldA) is the principal enzyme with which pea bacteroids synthesize alanine de novo. In free-living culture, AldA activity is induced by carboxylic acids (succinate, malate, and pyruvate), although the best inducer is alanine. Measurement of the intracellular concentration of alanine showed that AldA contributes to net alanine synthesis in laboratory cultures. Divergently ...
متن کاملDraft genome of the strain RCAM1026 Rhizobium leguminosarum bv. viciae
Rhizobium leguminosarum bv. viciae RCAM1026 is a strain first isolated in 1964 from nodules of "Ramensky 77" cultivar of garden pea (Pisum sativum L.) now routinely used as a model strain in inoculation experiments on pea. Assembly with SPAdes yielded 133 contigs longer then 200 bp (N50 = 202,321, GC% = 60.84). Resulting annotated genome is 7,248,686 bp encoding 6792 genes.
متن کاملSymbiotic plasmid rearrangement in Rhizobium leguminosarum bv. viciae VF39SM.
A rearrangement between the symbiotic plasmid (pRleVF39d) and a nonsymbiotic plasmid (pRleVF39b) in Rhizobium leguminosarum bv. viciae VF39 was observed. The rearranged derivative showed the same plasmid profile as its parent strain, but hybridization to nod, fix, and nif genes indicated that most of the symbiotic genes were now present on a plasmid corresponding in size to pRleVF39b instead of...
متن کاملGenetics and biotechnology of the H(2)-uptake [NiFe] hydrogenase from Rhizobium leguminosarum bv. viciae, a legume endosymbiotic bacterium.
A limited number of strains belonging to several genera of Rhizobiaceae are capable of expressing a hydrogenase system that allows partial or full recycling of hydrogen evolved by nitrogenase, thus increasing the energy efficiency of the nitrogen fixation process. This review is focused on the genetics and biotechnology of the hydrogenase system from Rhizobium leguminosarum bv. viciae, a freque...
