Assimilation of phenols by soybean bacteroids.
نویسندگان
چکیده
It has already been reported that several strains of different species of rhizobia are capable to degrade the phenolic compounds catechol, p-hydroxybenzoic, salicylic, and protocatechiuc acids (HUSSEIN et al. 1974). GUPTA and AGGRAWAL (1973) also reported the degradation of vanillin by some strains of rhizobia. However, nothing was published about the ability of bacteroids to degrade such compounds or the more complicated phenols, such as syringic and ferulic acids. The present communication is an attempt to test the ability of soybean bactuoids to degrade the above mentioned phenols.

Enzymes of ammonia assimilation and ureide biosynthesis in soybean nodules: effect of nitrate.
The effect of nitrate on N(2) fixation and the assimilation of fixed N(2) in legume nodules was investigated by supplying nitrate to well established soybean (Glycine max L. Merr. cv Bragg)-Rhizobium japonicum (strain 3I1b110) symbioses. Three different techniques, acetylene reduction, (15)N(2) fixation and relative abundance of ureides ([ureides/(ureides + nitrate + alpha-amino nitrogen)] x 10...
متن کاملUtilization of aldehydes and alcohols by soybean bacteroids.
Aldehydes, alcohols and acids were tested for their ability to support acetylene reduction and oxygen consumption by Rhizobium japonicum bacteroids isolated from soybean nodules. Several alcohols and aldehydes increased acetylene reduction and oxygen uptake. This is consistent with the concept that the plant nodule cytosol can metabolize carbohydrate via anaerobic fermentative pathways.
متن کاملOn the DNA Content of the Bacteroids of Rhizobium japonicum
DNA Content, Nodules, Bacteroids, Rhizobium, Soybean The DNA content of bacteroids from large nodules of soybean plants infected with Rhizobium japonicum strain 61 -A -101 was found to be 1.20 x 10~14 g per cell. Bacteroids from smaller nodules had slightly less DNA as did the stationary phase, free-living cells; both giving a value of 0.92 x 10-14 g per cell. In comparing these data with those...
متن کاملViability of Rhizobium bacteroids.
Bacteroids prepared from nodules of soybean and bean were tested for viability. Contrary to the prevailing view that bacteroids are nonviable, it was found that bacteroids averaged 90% viability, irrespective of Rhizobium strain, nodule age, or nodule environment.
متن کاملThe Oxidative Properties of Mitochondria and Bacteroids from Root Nodules of Soybean Treated with Organic Acids
Nodule mitochondria are highly sensitive to the respiratory inhibitor antimycine A. The antimycine-resistant oxygen uptake is 5–10% of the rate of control mitochondrial respiration. The high sensitivity to this inhibitor means that non-phosphorilating pathways are absent from the nodules and the energetic effectiveness of mitochondria is very high. The latter is proved by the good respiratory c...
