(n.) A spore, or conceptacle containing zoospores.
Example Sentences:
(1) By using reciprocal shift experiments (transferring sporulating cells from 22 to 27 degrees C and vice versa) we characterized the timers of the phenotypes: septate zoosporangium, papillate zoosporangium, cleavage zoosporangium, and empty zoosporangium, considering the number of the components, sensitivity, duration, and the mutual dependency of each limiting factor.
(2) The fourth phenotype, empty zoosporangium, has a timer which appears to act sequentially to that of the papillate zoosporangium.
(3) The first drug prevents the appearance of the septate zoosporangium and the other two prevent the expression of the papillate zoosporangium.
(4) The plurilocular zoosporangium of Ectocarpus parvus Saunders in initiated as a uniseriate branch from a vegetative cell.
Zoospore
Definition:
(n.) A spore provided with one or more slender cilia, by the vibration of which it swims in the water. Zoospores are produced by many green, and by some olive-brown, algae. In certain species they are divided into the larger macrozoospores and the smaller microzoospores. Called also sporozoid, and swarmspore.
(n.) See Swarmspore.
Example Sentences:
(1) Using zoospore capture technique, 361 colonies of aquatic freshwater fungi were recovered from sewage effluents, out of which 341 reached sexual maturity.
(2) Zoospores of Dermatophilus congolensis were analysed by SDS-PAGE and western blotting.
(3) The pattern of differential inhibition exhibited by sporangia versus zoospores upon treatment with actinomycin D, 4-FLUOROURACIL, OR CYCLOHEXIMIDE INDICATED THat continued translation on preformed messenger RNA may be one essential requirement for the formation and release of zoospores, whereas their subsequent germination and development may depend upon renewed transcription as well.
(4) It is proposed that simple, eucarpic, monocentric chytrids which discharge zoospores following dissolution of the sporangium wall evolved into multipapilliate species of Rhizophydium and 2 lines of evolution from these species are documented with examples.
(5) Discharge of zoospores is also cited as important although emphasis is not placed on operculation.
(6) Zoospores were produced in water held at 15, 20 and 25 degrees C and were pathogenic for Ae.
(7) The observations that some of the newly synthesized RNA and protein occur in the intact 82S ribosomes and that actinomycin inhibits the low level of protein synthesis provide some indirect evidence for a very low rate of "messenger" synthesis and turnover in zoospores.
(8) Comparison of RNA synthesis during germination of B. ramosa and Blastocladiella emersonii zoospores revealed that B. ramosa has a longer lag time before RNA synthesis is initiated and, in addition, the rate of RNA synthesis is ten-fold lower in B. ramosa.
(9) Zoospores of Australian isolates of Phytophthora drechsleri, P. cryptogea, P. cinnamomi, P. nicotianae var.
(10) The vegetative stage strongly resembled that of certain species of aquatic phycomycete fungi, and the flagellates may therefore by zoospores.
(11) Zoospores of Oomycetes contain a variety of microbody-like organelles with highly structured matrices.
(12) Fungal colonies developing in anaerobic media from zoospores in rumen fluid from cows eating Cynodon dactylon or Medicago sativa included types showing monocentric and polycentric growth.
(13) During early germination posttranslational control was also observed, several labeled proteins from zoospores being specifically degraded or charge modified.
(14) In suppressive soils this association appears to be correlated with hyphal lysis, inhibition of zoospore production, and sporangial breakdown.
(15) The water mold Blastocladiella emersonii releases zoospore maintenance factor into the medium during zoosporogenesis.
(16) Zoospores bound concanavalin A (Con A), but did not bind any of a variety of other lectins tested.
(17) These features are the presence of hydrogenosomes at all stages of the life cycle, the presence in rhizoids and sporangia of characteristic crystals coated with hexagonal arrays of particles, and in zoospores the presence of distinct surface layers on the motility organelles and cell body respectively, the organization of the ribosomes into helical and globular arrays and the structures associated with the kinetosomes.
(18) In germinating zoospore cysts of the oomycete Phytophthora capsici the mechanism of action of taxol was shown to involve inhibition of mitosis, presumably resulting from an effect on microtubules.
(19) Sufficient inducer was present in the normal diet of the host animal to trigger the differentiation and release of the zoospores from all the sporangia of each phycomycete species present in the rumen fluid tested.
(20) Zoospores of B. ramosa were shown to contain pre-formed messenger RNA but this messenger RNA directs only a portion of the protein synthesis which occurs during early germination.
