(1) The results show that upon illumination of dark thalli (a) a reduction in thickness of thylakoid membranes (conformational change), (b) a more regular ordering, and (c) flattening of the thylakoids (configurational changes) have occurred.
(2) Saline phosphate buffer pH 7.2 extracted the bulk of the hemolysin from the lichen thalli.
(3) Cytochrome b-562.5 (Ulva pertusa) was extracted from a green alga, U. pertusa, by homogenization of the thalli in phosphate buffer solution.
(4) A mathematical model of the life cycle of anaerobic fungi, based upon observations of the life histories and growth kinetics of these organisms in vitro and in vivo, is constructed and solved in the steady-state to determine the population of particle-attached (substrate-associated) fungal thalli from the concentration of free-swimming zoospores in rumen liquid.
(5) These peaks are of chlorophastic origin as confirmed by the following facts: the labelling is light-activated; plastids isolated from thalli labelled for 12 h also show these two radioactive peaks.
(6) The microbial elements were composed of spores, thalli and multilocular tubers.
(7) However, if thalli possessing recently-formed sporangia were transferred to, or flooded with, fresh liquid medium or rumen fluid, zoosporogenesis and liberation of zoospores occurred within 17-20 min for isolates LL and LC2 and 30 min for R. elegans.
(8) Plant material entering the rumen is rapidly colonized by zoospores that attach and develop into thalli.
(9) In this paper the electrofusion of protoplasts from P. haitanensis and P. yezoensis thalli by using an electrofusion instrument (Shimadzu Company, Japan) under different conditions of AC field, DC pulse, fusion buffer solutions and concentrations of protease are described.
(10) Well developed flagella, complete with basal bodies, were observed in young thalli.
(11) A photosynthetic c-type cytochrome, cytochrome c6, was extracted from a green alga, Bryopsis maxima, by cutting and immersing the frozen thalli in phosphate buffer, pH 7.0, and purified by acrinol treatment, ammonium sulfate fractionation, DEAE-Sephacel chromatography and Bio-Gel P-10 gel filtration.
(12) In this work it was found that 0.1 mM cycloheximide seems to inhibit PIUS synthesis when lichen thalli are incubated on PIUS inducer, L-arginine.
(13) Zoospores encyst, shedding their flagella with basal bodies, and germinate to diglobular thalli.
(14) In the coiled apex of the mature thalli, the septa form two catogeries of unisporates sporangia leading to two types of spores.
(15) The ultrastructural basis of light-induced transmission and light scattering changes of thalli of Ulva and Porphyra were investigated by high resolution electron microscopy and microdensitometry.
Thallic
Definition:
(a.) Of or pertaining to thallium; derived from, or containing, thallium; specifically, designating those compounds in which the element has a higher valence as contrasted with the thallous compounds; as, thallic oxide.
Example Sentences:
(1) The structure and oxidation state of the thallium reagent used affected the extent of modification by the compounds MPT, o-carboxyphenylthallium(III) bis-trifluoroacetate, thallic trifluoroacetate and thallous acetate.
(2) Conidiogenesis that gives rise to multiple, broad-based blastic and thallic-sarcinic conidia characterizes S. phaeomuriformis.
(3) A number of fungi, such as anamorphs of Onygenales which includes many of the fungi pathogenic to man, demonstrate intergradations between blastic and thallic development.
(4) In 1969, specialists at the Kananaskis hyphomycete workshop coined the terms 'blastic' and 'thallic' to describe two distinct modes of conidiogenesis.
(5) The alternating thallic arthroconidia were released by fracturing of the adjacent sterile cells.
(6) The latter protected only against the fast phase of thallic modification, the slower phase being unaffected.
(7) The one-electron oxidation of DNA bases and single-stranded DNA was studied by pulse radiolysis of aqueous solutions from pH 7-7.4 at 20 degrees C. Thallic ions, Tl(II), were found to rapidly oxidize the purine nucleotides, deoxyguanosine 5'-monophosphate, k[Tl(II) + dGMP2-] = 3.4.10(9) M-1.s-1, and deoxyadenosine 5'-monophosphate, k[Tl(II) + dAMP2-] = 1.3.10(8) M-1.s-1.
(8) In contrast to thallous acetate, thallium(III) derivatives (thallic trifluoroacetate, p-methylphenylthallium(III) bis-trifluoroacetate (MPT) and o-carboxyphenylthallium(III) bis-trifluoroacetate) bound to Escherichia coli tRNA.
