  • Title: Amplicon restriction patterns associated with nitrogenase activity of root nodules for selection of superior Myrica seedlings.
    Author: Yanthan M, Misra AK.
    Journal: J Biosci; 2013 Nov; 38(4):789-95. PubMed ID: 24287658.
    Abstract:
    Trees of Myrica sp. grow abundantly in the forests of Meghalaya, India. These trees are actinorhizal and harbour nitrogen-fixing Frankia in their root nodules and contribute positively towards the enhancement of nitrogen status of forest areas. They can be used in rejuvenation of mine spoils and nitrogen-depleted fallow lands generated due to slash and burn agriculture practiced in the area. We have studied the association of amplicon restriction patterns (ARPs) of Myrica ribosomal RNA gene and internal transcribed spacer (ITS) region and nitrogenase activity of its root nodules. We found that ARPs thus obtained could be used as markers for early screening of seedlings that could support strains of Frankia that fix atmospheric nitrogen more efficiently.
