Abstract

Summary: Bacteroids from effective nodules of subterranean clover were ovoid, pear-shaped, or slightly branched and measured 5-7 × 4-6 μ. In the fully developed bacteroid the nuclear material was central, divided into discrete bodies and showed signs of degeneration. Surrounding the nucleus was a perinuclear region, probably derived from it, and this was surrounded by cytoplasm which contained several mitochondria-like granules. The development of bacteroids from rod-shaped cells is described. Bacteroids from the ineffective nodules studied possessed no perinuclear region, and, in contrast to those from effective nodules, accumulated varying amounts of glycogen, depending on the length of time for which the bacteroids survived in the host cell.
