Answer to Question #280333 in Microbiology for Tyan

Question

Do you think bacteroid is indifferent from a typical Rhizobium? If yes/no- justify your answer.

2. Write down the role of flavonoids and leg hemoglobin in the infection process by Rhizobia.

3. What do you understand by oxidation and reduction reaction? Write down the different types of the oxidation and reduction reactions (with the name of end product) that occur in the sulfur cycles?

4. Soil bacteria conduct N-fixation by two different ways, write down the similar and different characteristics between these N-fixation processes?

Answer 1

1.Yes, plants rely on minerals like phosphorous, nitrogen, and sulfur being existing in an accessible form, which can limit their development. Mutualistic symbiotic relationships among plants and origin microbes have developed to aid nutrient absorption.

2) Flavonoids play a key role in the connection by inducing transcription of genes involved in the manufacture of rhizobia regulatory substances known as Nod components, which the plant interprets as allowing symbiotic root invasion.

3) The phrases redox and reductive refer to the process of generating or expelling oxygen from a molecule. The process of gaining oxygen is known as oxidation. The depletion of oxygen is referred to as reduction.

4) Nitrogen fixing occurs naturally in soil by diazotrophic microbes, which encompass bacteria like Azotobacterial and archaea. Plants, particularly lentils, have symbiotic interactions with certain nitrogen-fixing microbes.
