Invasion of Palmaria mollis by the marine oomycete Petersenia palmariae begins with penetration of the cell wall and then the lumen of an outer cortex cell. The fungus in its vegetative phase lacks a wall but is separated from the host cytoplasm by the invaginated plasmalemmaof the host cell. By promoting fusion of host cells or by the dissolution of the host cells' pit plugs, the fungus is able to use a symplastic route to invade cells deep in the cortex and medulla of the host. In the process, a compound confluent host cell lumen is created. The deposition of a thick wall around the lobed fungal cell marks the beginning of holocarpic sporangium formation and is followed by great proliferation of the parasite's nuclei and concomitant diminution of nuclear and nucleolar size. The cytoplasm becomes parietal when a large central vacuole develops. Mastigonemes are formed in dilated endoplasmic reticulum, mitochondria become associated with nuclei, and cleavage begins. Flagella begin to form on paired basal bodies before cleavage is complete. Following a period of motility, zoospores retract and then resorb their flagella. The naked spores develop walls and the basal bodies persist as centrioles.

Nucleolar Size

Nucleolar size and appearance correlate with ribosome biogenesis and cellular activity. The mechanisms underlying changes in nucleolar appearance and regulation of nucleolar size that occur during differentiation and cell cycle progression are not well understood.Caenorhabditis elegansprovides a good model for studying these processes because of its small size and transparent body, well-characterized cell types and lineages, and because its cells display various sizes of nucleoli. This paper details the advantages of usingC. elegansto investigate features of the nucleolus during the organism's development by following dynamic changes in fibrillarin (FIB-1) in the cells of early embryos and aged worms. This paper also illustrates the involvement of thencl-1gene and other possible candidate genes in nucleolar-size control. Lastly, we summarize the ribosomal proteins involved in life span and innate immunity, and those homologous genes that correspond to human disorders of ribosomopathy.
