What is the function of leghaemoglobin in the root nodules of legumes?

Leghaemoglobin sounds similar to haemoglobin. The function of it is also similar to the haemoglobin in the blood of a human body. Let us learn about leghaemoglobin in this article.

What is leghaemoglobin?

Leghaemoglobin is like haemoglobin like red pigment in the root nodules of leguminous plants, as soybean, that is essential for nitrogen fixation. It acts as an oxygen scavenger.

Functions of leghaemoglobin

  • Leghaemoglobin is a red-coloured pigment found in the root nodules of leguminous plants.
  • It combines with oxygen and thus helps in oxygen removal from root nodules.
  • It helps to scavenge the limited free oxygen in the cell and deliver it to mitochondria for respiration.
  • It is responsible both for buffering oxygen concentration, and for delivery of oxygen to mitochondria
  • It is a hemoprotein for the plants.
