Vacuolation and infection thread in root nodules of soybean.
Profuse vacuolation takes place in the soybean root nodule cells where infection threads carry rhizobia. After the rhizobia are released the disappearance of the infection thread is attributed to its degradation within large vacuoles which result from fusion of small vacuoles.
