When comparing nodule specific nitrogenase activitiies in control and nitrate treated plants at 20% oxygen, why is it necessary to express nitrogenase activity per gram fresh weight of nodule tissue?
Nitrogen fixation - Undere natural condiitions , O2 concentration never increases to 30%. Under what circumstances would you expect nodule O2 concentration to increase under natural conditions?
Nitrogen cycle - Gardeners are often told to plant legumes because they improve the soil by adding nitrogen? Is this statement correct? Please explain.
Symbiotic nitrogen fixation by Rhizobium - As part of a practical we had to grow Rhizobium inoculated white clover seedlings in nitrate free agar and inoculated seedlings in nitrate free and nitrate supplemented medium. After several weeks of ...
How can you examine the plant species specificity of Rhizobium spp? - All I can think of is inoculating lots of different types of plant seedlings with the bacteria and comparing their growth with uninoculated seedlings.
As the specificity of Rhizobia-plant interacti ...
