Trace the events starting from the coming in contact

Event 1: Trace the events starting from the coming in contact with Rhizobium to a leguminous root till nodule formation. Add a note on the importance of leghemoglobin.

Event 2: The root hair cells curl and the bacteria enter the root hairs.

Event 3: After entering the root hair an infection thread is formed.Which carries the bacteria to the cortex of the root.

Event 4: Formation takes place in the cortex nodule

Event 5: The differentiation of nitrogen-fixing cells takes place

Event 6: Avascular connection is established with the host for the exchange of nutrients.

Leghaemoglobin is considered as the oxygen molecule scavenger helping enzyme nitrogenase in nitrogen fixation, which only works in the absence of molecular.
