Development and histopathology of Rotylenchulus reniformis in sweet potato roots
and
The reniform nematode, Rotylenchulus reniformis, completed its life cycle in feeder roots of sweet potato in 17-2l days after planting. Infected roots showed thick-walled cells in the cortex and endodermis, pitted tracheid and giant cells. Cork-like cells which resulted from hyperplasia in the cortex, enclosed the mature nematodes within the root tissue and resulted in the development of galls on the roots.
