Genetics Section Wiggers, Robert [1], Gravatt, Dennis [1]. Observations On Nucleoli Of Meloidogyne (Nematoda) Induced Giant Cell Nuclei. Nematodes of the Meloidogyne genus induce the formation of large, multinucleate giant cells in their hosts. These giant cells have elevated metabolic processes and supply the developing nematode with all necessary nutrients. Long known to possess elevated DNA content and chromosome counts, this study examined the nucleoli of giant cell nuclei. As compared to root tip nuclei from uninfected plants, giant cells at one and two weeks post inoculation had a significantly larger percentage of their nuclei occupied by nucleoli. This difference had disappeared by 3 weeks post inoculation. These disproportionately enlarged nucleoli may be required to enable the giant cells to meet increased metabolic demands made by the maturing nematode. Log in to add this item to your schedule
