Trace the events starting from the coming in contact of Rhizobium to a leguminous root till nodule formation. Add a note on importance of leg hemoglobin
There are commonly six events occur between the starting from the coming in contact with Rhizobium to a leguminous root till nodule formation.
Event 1: Rhizobia multiply and colonize the surroundings of roots and get attached to epidermal and root hair cells.
Event 2: The root hair cells curls and bacteria enters the root hairs.
Event 3: After the entry of bacteria in the root hair an infection thread is formed which carried bacteria to the cortex of the root.
Event 4: Formation of nodule initiates in cortex.
Event 4: The bacteria are released from the thread into the cells which leads to the differentiation of specialized nitrogen fixing cells.
Event 6: Nodule formed a vascular connection with the host for the exchange of nutrients.
Importance of leghemoglobin:
Enzyme nitrogenase only work in anaerobic condition, thus leghemoglobin helps in this.
