Rhizobium-induced Root nodulation of Parasponia

Rhizobium-induced Root nodulation of Parasponia
This unique association between a Rhizobium and a non-leguminous plant has been demonstrated in the genus Parasponia (also described as Trema),Cluster or Proteoid roots in Casuarian equisetifolia-A-under natural conditions in soil and B-under laboratory conditions in a perlite substrate in pot in a growth chamber.belonging to the family Ulmaceae in 3 out of 5 species of the genus-P. rugosa, P. parviflora and P. andersonii.

The structure of the root nodule resembles that of legume root nodules. However, unlike the infection thread in leguminous root nodules, in Parasponia root nodules rhizobia are very rarely released from infection threads which grow and fill the host cell. The isolation of Rhizobium from nodules is easy and nodulated plants exhibit demonstrable nitrogenase activity.
