Electron microscopic studies of the root nodule of pterocarpus indicus

Abstract

The morphology of the root nodules of Pterocarpus indicus Willd (“na-rra”) was studied by scanning and transmission electron microscopy and by light microscopy. The electron micrographs revealed that the nodule tissue cells gradually change from large to small size from the epidermal tissue to the inner core tissue. The epidermal cells have hard and thick cell walls surrounded by cork. The inner core cells have very thin cell walls (about 0.3 μm thick). The inner core cells contain numerous bacteroids (1-1.5 x 2-4.5 μm in size). © 1987, Applied Microbiology, Molecular and Cellular Biosciences Research Foundation. All rights reserved.
