متن کاملIsolation and Characterization of Agrobacterium rhizogenes from the Root Nodules of Some Leguminous Plants
A total of 57 colonies of Agrobacterium species was isolated from the root nodules of five different leguminous plant namely Pisum sativum, Sesbania rostrata, Vigna mungo, V. radita and V. ungiculata by using yeast extract mannitol agar (YEMA). All the isolated colonies were belonged to Agrobacterium species. The isolated bacteria were characterized and identified as Agrobacterium rhizogenes ba...
متن کاملOxidation and reduction of leghemoglobin in root nodules of leguminous plants.
Reactions involving changes that affect the function of leghemoglobin (Lb) are reviewed. The chemical nature of Lb and conditions inside nodules, such as slightly acid pH and the presence of metal ions, chelators, and toxic metabolites (nitrite, superoxide radical, peroxides), are conducive for oxidation of ferrous Lb (Lb(2+)) or its oxygenated form (LbO(2)) to nonfunctional ferric Lb (Lb(3+)) ...
متن کاملIsolation and Characterization of Phb Producing Micro-organisms Isolated from Root Nodules of Leguminous Plants
A number of the micro-organisms are capable of producing polyhydroxyalkanoates (PHA’s) as storage food reserve under unbalanced growth conditions. The mechanical properties of PHA’s are similar to that of synthetic plastics like polyethylene, polypropylene etc. The advantage of using PHA’s over synthetic plastic is that PHA’s are completely mineralized into carbon dioxide and water through the ...
متن کاملLateral fusion of membranes in bacteroid-containing cells of leguminous root nodules.
Bacteroid-containing cells of leguminous root nodules (Pisum and Trifolium) provide an environment in which the membrane envelope surrounding each bacteroid can exhibit unusual properties. The bacteroids are crowded, and frequently neighbouring membrane envelopes come into close contact. In such cases the two envelopes can fuse laterally to give a symmetrical tripartite membrane, probably consi...
