What's the difference between asci and paraphyses?
Asci
Definition:
(n. pl.) See Ascus.
Example Sentences:
(1) Although growth of two yeast strains characterized by consistent production of two diploid spores per ascus was inhibited in complex presporulation media containing amitrole, a fraction of the cells produced were able to form asci with more than two spores after transfer to acetate sporulation medium.
(2) The species forming asci from conjugating gametangial cells and having ellipsoidal ascospores are transferred to Dipodascus.
(3) Afterwards, a septum was formed in the channel connecting the two cells which turned into asci or formed buds which became asci.

(5) The proportion of spindle overlap and recombinational asci within the group did not change as shown by ascus dissection.
(6) Diploids carrying these suppressors upon sporulation yield asci with only two live spores, both lacking the suppressor.
(7) In the three spored asci, which occur rarely, only one nucleus is surrounded by a spore wall after meiosis I; the other nucleus undergoes meosis II before the onset of spore wall formation.

(9) Among meiotic asci produced by triploid (3N) Saccharomyces cerevisiae are cases in which exactly two of the four ascospores proliferate into colonies.
(10) In cdc1-7, cdc5-120, cdc17-L16 and cdc18-46 no abnormalities were observed; cdc10-129, cdc20-M10, cdc21-M6B, cdc23-M36 and cdc24-M38 formed four-spored asci but with a low efficiency; cdc22-M45 was completely defective in meiosis, but could conjugate and formed zygotes with a single nucleus.
(11) Two of the sg-mutants (sg 2 and sg3) produced abundant cleistothecia with asci and ascospores when back crossed to parents of opposite mating type.
(12) Yeast vegetative cells were stained reddish purple, but zygotic asci were bluish.
(13) The increase in spore numbers per ascus is attributed either to the induction by amitrole in growth medium of cells with more than one nucleus or to the restoration of normal meioses in the multispored asci.
(14) Summation of results for 10 individually sized AscI fragments estimated the genome length to be 1,861 kb for the four strains (H, PAC1.0, PO2, and JBL1350) with identical fingerprints.
(15) Dissection of asci from these clones yielded some single-spore clones which showed mating reactions with one or the other or both haploid tester strains, and further selection produced strains which on sporulation and dissection yielded single-spore clones which were apparently bisexual and sporulated freely.
(16) The SMO genetic locus in strains of the fungus Magnaporthe grisea that infect weeping lovegrass, directs the formation of correct cell shapes in asexual spores, infection structures, and asci.
(17) The Eight-spore gene E, which shows variable penetrance, was used to obtain N. tetrasperma asci in which two to eight spores are small and homokaryotic.
(18) In one case of suppression, the asci also show segregation at the plasmid level.
(19) Each plasmid segregated from an intact unpaired copy of chromosome I at the first meiotic division in a significant majority (63-93%) of the asci examined.
(20) A physical map of the chromosome was constructed for NotI, AscI, and SrfI by using single and double digests, or partial NotI digests obtained at random or by cross-protection of NotI sites by FnuDII methylase, and linking clones.
Paraphyses
Definition:
(pl. ) of Paraphysis
Example Sentences:
(1) Serotonin, norepinephrine and epinephrine contents of the pineal-paraphyseal complex were measured spectrofluorometrically 24 h after the last injection.
(2) Concentric bodies were found in vegetative and pycnidial cells of Podoxythium tricothecium and in ascostromal paraphyses of Rhytidhysterium rufulum, two representatives of the Loculoascomycetes.
(3) The spectrofluorometric findings revealed that the serotonin, norepinephrine, and epinephrine contents of the pineal-paraphyseal complex decreased at 6 hr, increased at 12 hr, and declined again at 24 hr after the treatments.
(4) Depending on the stage reached at the time of exposure to the inhibitors, vegetative hyphal tips emerged from the four apical sites for sterigmata, from the tips of sterigmata, from partially formed or abnormal spores, and from the basal regions of the basidium from which paraphyses would be expected to arise.
(5) Nerve fibers were observed in the paraphysis, however, histofluorescence revealed no monoaminergic sympathetic innervation of the paraphyseal vasculature.
(6) The case is reported of a 26 year-old man with a colloid cyst of the third ventricle (paraphyseal cyst; neuroepithelial cyst), which gave rise to a fatal increase in intracranial pressure.
(7) The aim of the present investigation was to ascertain the influence of ambient temperature on serotonin, norepinephrine, and epinephrine contents in the pineal-paraphyseal complex of soft-shelled turtles.
(8) The results of this study indicate that paraphysectomy induces stimulation of the parathyroid glands and suggest a role for the paraphyseal-choroid plexus complex in the regulation of amphibian parathyroid gland function.
(9) Dehydration stress also modulates pineal-paraphyseal serotonin, norepinephrine and epinephrine concentrations.
(10) It is suggested that circadian rhythms exist in pineal-paraphyseal amines and indoleamine in juvenile turtles like that of adult turtles.
(11) The findings reveal that there is a distinct circadian rhythm in serotonin, norepinephrine, and epinephrine contents of the pineal-paraphyseal complex in adult male soft-shelled turtles.
(12) The relationship of the paraphyseal-choroid plexus complex to parathyroid gland function was investigated in adult frogs.
(13) The findings revealed that ambient temperatures significantly altered serotonin, norepinephrine, and epinephrine content in the pineal-paraphyseal complex of turtles.
(14) Three separate approaches, by way of anthropomorphic psychology, a paraphysical energy model and the physical theory of the implicate order, lead to the recognition of a certain inseparability of 'self' and 'congener'; and to an interpretation of the content of the notion of congener and of the behaviour in relation to it, in terms of the fundamental concept of energy and the even more fundamental one of order.
(15) Its developmental relationship to previously described colloid and paraphyseal cysts in the third ventricle is discussed.
(16) Light microscopy and morphometric analysis indicated that total parathyroid gland volume, cell volume and vascular volume doubled by 7-28 days after surgical removal of the paraphyseal-choroid plexus complex (paraphysectomy).
(17) It is also suggested that light greatly modulates serotonin, norepinephrine, and epinephrine contents in the pineal-paraphyseal complex of the soft-shelled turtle.
(18) To further elucidate its possible endocrine role, the paraphyseal vasculature was examined using casting techniques as well as transmission electron microscopy.
(19) Perfusion-fixed paraphyses of Rana pipiens and Rana catesbeiana were either: a) cast with Microfil (with subsequent dehydration, clearing, and macroscopic examination) or Batson's compound (followed by tissue digestion and examination by scanning electron microscopy); or b) processed for transmission electron microscopy.
(20) It is suggested that reserpine and chlorpromazine act largely by favoring release with transient resynthesis of these amines in the pineal-paraphyseal complex of soft-shelled turtles.
