Ultrastructural pathology of cells affected by Pratylenchus penetrans in alfalfa roots

Cortical parenchyma cells penetrated and fed upon by Pratylenchus penetrans for 48 hours contained only cytoplasmic debris. Proximal cells had an increase in tannin deposits, degenerated mitochondria, increased numbers of ribosomes, and no internal membrane structure. Often the endodermis was collap...

description	Cortical parenchyma cells penetrated and fed upon by Pratylenchus penetrans for 48 hours contained only cytoplasmic debris. Proximal cells had an increase in tannin deposits, degenerated mitochondria, increased numbers of ribosomes, and no internal membrane structure. Often the endodermis was collapsed and contained massive tannin deposits on the inner cell wall and cell lumen. Similar observations were made in the stele, except tannin deposits were not as prominent. Multivesicnlate structures were observed both in the endodermis and in the stele.
