What is the difference between giant cells (induced by root-knot nematodes) and syncytium (induced by cyst nematodes)?

25 March 2014 1 7K Report

Those kinds of cells are induced in the host plant roots and cause hypertrophy and hyperplasia, but what makes it different?

Gonzalo Galileo Rivas Platero

The giant cells of root-knot nematodes are formed by repeated karyokinesis uncoupled from cytokinesis, whereas the syncytia formed by cyst nematodes arise from coordinated cell wall dissolution and the coalescing of cell cytoplasm of adjacent cells.
