Amitochondriate amoebae and the evolution of DNA-dependent RNA polymerase II.
Unlike parasitic protist groups that are defined by the absence of mitochondria, the Pelobiontida is composed mostly of free-living species. Because of the presence of ultrastructural and cellularExpand
Conchospore production and seasonal occurrence of some Porphyra species (Bangiales, Rhodophyta) in Washington State
TLDR
Data from laboratory studies of conchospore formation and release in five Washington species of Porphyra indicate that con chospores are most likely to be released at a time that precedes the appearance of the leafy thalli in the field. Expand
Morphogenesis in the red alga, Griffithsia pacifica: Regeneration from single cells
TLDR
The regeneration of plants of the red alga Griffithsia pacifica from single, isolated cells is described, and the predictability and rapidity of this development combined with the large size of these cells facilitate developmental studies on this organism. Expand
Conchospore production and seasonal occurrence of some Porphyra species (Bangiales, Rhodophyta) in Washington State
The leafy thalli of species of the marine red algal genus Porphyra grow rapidly but persist for a relatively short time on rocky intertidal or subtidal substrata or as epiphytes on other marineExpand
