The Zoospores of Chroolepus, Ag*

Journal of Cell Science
ABSTRACT The first of the plants to which the observations refer is Chroolepus aureum, Spr. var. tomentosum, Kg. Under the microscope, the plant is seen to be formed of erect threads, intermixed with branched threads, each consisting of a single row of cells. The walls are colourless, but with a glittering appearance. (Pl. IX, fig. 1, s.)

Green matter, zoospores, and diatoms

2023
Abstract The gravest risks to a sharp plant-animal dichotomy arose at the interface between infusoria and algae. This chapter treats four case studies: the “green matter” debate initiated by Priestley in the 1770s; the recognition of motile “zoospores” after 1803; experiments on algal metamorphosis from the 1810s through the 1840s; and ...

CHLOROPLAST INCLUSIONS IN ZOOSPORES OF OEDOCLADIUM1

Journal of Phycology, 1974
SUMMARYChloroplast inclusions have been studied in zoospores of Oedocladium carolinianum and their ultrastructure compared with the same inclusions previously described in the related genera Oedogonium and Bulbochaete. Structure of the mature pyrenoids is consistent in all 3 genera; the pyrenoid matrix is penetrated by branched cytoplasmic channels ...

Effects of calcium on germination and further zoospore release from zoospore cysts of Phytophthora parasitica

Mycological Research, 1996
Cysts of Phytophthora parasitica, induced by vortex treatment of zoospore suspensions, germinated poorly when held in Eppendorf tubes but germinated well when transferred to glass slides within the first few minutes of encystment. The responsiveness to a surface, or to other treatments where tested, was lost after 12-15 min in the Eppendorf tubes ...

Zoospores-on-a-Chip : the development of a microfluidic platform to measure electrotactic responses of oomycete zoospores.

Oomycetes are filamentous microorganisms that are morphologically and nutritionally similar to fungi. Some oomycete species, most notably those in the Phytophthora genus, can become pathogenic, and these can have huge impacts on ecosystems with the potential loss of biodiversity.
