The root nodules isolated from smaller plants were clearly visible ( as shown in previous post). But some plants that were having thick and robust roots showed prolific growth. Are these galls or root knots ? I am unable to describe. On gentle teasing, followed by staining with methylene blue, I was able to diagnose certain nodule-like individual structures. I will try out a smear of the bacteria isolated from these and go for gram’s staining.
