 Title    The Effects of the Herbicide Sethoxydim on Transport Processes in Sensitive and Tolerant Grass Species I. Effects on the Electrical Membrane Potential and Alanine Uptake  
 Abstract    Sethoxydim is a postemergence herbicide used to control grass weeds. Application at concen-trations higher than 0.1 mM to leaf segments of the sensitive grass species Poa pratensis and Festuca ovina and the tolerant species Poa annua and Festuca rubra, caused a reduction of the electrical membrane potential (AE). The depolarization was reversible and depended linearly on the herbicide concentration. The passive diffusion component of AE was not affected by sethoxy-dim indicating that the herbicide did not change passive permeability characteristics of the plas-malemma. Consequently sethoxydim reduced the active component of AE that depended on primary active transport processes across the plasmalemma. Moreover, sethoxydim increased the reduction of AE of grass leaf cells that was associated with the onset of H + -amino acid cotrans-port. Simultaneously the uptake of alanine into leaf segments was reduced. From these results it had to be concluded that the plasmalemma-bound H + -ATPase was inhibited by sethoxydim in sensitive and tolerant grasses. In vitro ATP hydrolysis of plasmalemma vesicles isolated from grass leaves by polymer phase partitioning, however, was not inhibited by sethoxydim. Apparent-ly another primary active transport mechanism that may contribute to an electrochemical H + -gradient across the plasmalemma, i.e. a plasmalemma-bound redox system, should be the site of inhibition responsible for the membrane effects of sethoxydim observed in vivo.

 Title    The Effects of the Herbicide Sethoxydim on Transport Processes in Sensitive and Tolerant Grass Species II. Effects on Membrane-Bound Redox Systems in Plant Cells  
 Abstract    Leaf slices of sethoxydim-sensitive (Poa pratensis, Festuca ovina) and tolerant (Poa annua, Festuca rubra) grass species were found to be able to reduce extracellular ferricyanide by electron transport across the plasmalemma. This reduction was inhibited by the herbicide sethoxydim, and the sensitive species were much more strongly affected than the tolerant ones. The inhibition was concentration dependent. Sethoxydim affected the electron transport in isolated Poo chloroplasts. Polarographic and photometric measurements of ferricyanide reduction suggested photosystem II to be the site of action. Inhibition occurred only in the sensitive species Poa pratensis and was linearly dependent on concentration. In isolated mitochondria from sensitive Zea mays coleop-tiles sethoxydim also acted as an inhibitor of electron transport. Only slight inhibition was meas-ured with mitochondria from tubers of tolerant potato (Solanum tuberosum). It is concluded that sethoxydim generally acts as inhibitor of membrane-bound redox systems. The specific inhibition of the plasmalemma-bound redox system of sethoxydim-sensitive plants could contribute to a selective action of the herbicide.

 Title    Effect of Inhalation Anesthetics on Spin-Labeled Cholesterol Containing DPPC Vesicles  
 Abstract    We have investigated by means of electron spin resonance (ESR) spectroscopy the influence of three inhalation anesthetics, i.e. halothane, chloroform and diethyl ether, on the interfacial and hydrophobic region as well of 38 mol% cholesterol containing DPPC unilamellar vesicles. The study has been carried out in the temperature range 25-45 °C. The variation of the order parameter, S, vs temperature of the lipid phase indicates that with this content of cholesterol the characteristic gel liquid crystalline main phase transition of DPPC, normally occurring at T x ~ 41 °C, disappears. When halothane and chloroform are added to the vesicles suspension up to [DPPC]/[anesthetic] molar ratio of 1:1 the main phase transition, as detected with the stearic acid spin label 7(12,3), reappears again and it results down shifted at 7, ~ 35 and 39 °C, respectively. In presence of diethyl ether, instead, the main phase transition is not observable also at the highest concentration of anesthetic used. Moreover, halothane and chloroform affect similarly the hydrophobic core of choles-terol-!-DPPC vesicles which, in turn, results to be different from the action exerted by diethyl ether in the same region. The ESR findings are discussed in terms of competitive effects shown by cholesterol and inhalation anesthetics. Moreover, the interfacial region of CHOL + DPPC vesicles results to be the target of anesthetics.

 Title      
 Abstract    The effects of short-time fumigation (0-60 min) of intact spinach leaves with S0 2 (2 ppm) on the photosynthetic apparatus were investigated. A rather high S0 2 concentration was applied to monitor immediate effects on the fluorescence behaviour with the influence of repair processes or secondary types of damage being minimized. Three different types of in vivo chlorophyll fluores-cence measurements were used: Rapid induction kinetics (Kautsky effect), slow induction kinetics with repetitive application of saturation pulses (saturation pulse method), and decay kinetics following a single turnover saturating flash. The slow induction kinetics with repetitive application of saturation pulses reacts in the most sensitive way indicating a primary damage at the level of the enzymatic reactions of the Calvin cycle. It is suggested that stromal acidification upon S0 2 uptake interferes with light activation of Calvin cycle enzymes. With longer fumigation times also damage at the level of photosystem II becomes apparent: A decrease in variable fluorescence yield reflects a lowering of photosystem II quantum yield, and the slowing down of fluorescence relaxation kinetics reveals an effect on the secondary electron transport from Q A to Q B . The detrimental effects of S0 2 depend to a great extent on the application of light during fumigation. Besides a light requirement for S0 2 uptake by stomata opening also the possibility of photoinhibitory damage is discussed. The susceptibility of leaves to photoinhibition may increase with a lowering of Calvin cycle activity by S0 2 .

 Title    Enzymatic Conversion and Degradation of Sex Pheromones in Antennae of the Male Silkworm Moth Antheraea polyphemus  
 Abstract    In living antennae of the male silkworm moth Antheraea polyphemus the pheromone com-pounds [6,7-3 H]-6,ll-hexadecadienyl acetate and [12,13-3 H]-10,12-hexadecadienol are enzymati-cally converted to their corresponding fatty alcohols, aldehydes, acids and long-chained fatty acid esters. In antennae of freshly hatched moths the 3 H-labeled pheromones are degraded at high rates to volatile polar metabolites. The half-life of the pheromone acetate is about 3 min. In dried antennae the pheromone acetate is merely hydrolyzed to the fatty alcohol.

 Title    Thermodynamic and Magnetic Resonance Studies on the Hydration of Polymers: II. Protein-Water Interactions in Powdered Ribonuclease  
 Abstract    ESR studies on spin-labeled amorphous RNase A as a function of varying concentrations of sorbed H 2 0 and D 2 0 will be presented. A relaxation analysis of saturation transfer (ST-)ESR spectra of l4 N('H) nitroxide spin-label molecules essentially fixed at amino acid residue His-105 will be given. A characteristic correlation has been observed between the microdynamic behavior — express-ed by the rotational correlation times of the paramagnetic label — and the macroscopic thermo-dynamic entropy for the sorption process of H 2 0 and D 2 0 at RNase. This correlation is particu-larly pronounced at low water concentrations, viz., n H20 /n protein < 100. A significant difference in this concentration range exists between the two systems "RNase-H 2 0" and "RNase-D 2 0", which is manifested not only by the thermodynamic data but also by the microdynamic behavior ex-tracted from the corresponding non-linear ESR absorption line shapes.

 Title    Growth Control and Pattern Regulation in the Lateral Line Systems of Xenopus  
 Abstract    In Xenopus, the supraorbital lateral line system consists of a periodic pattern of lateral line organs which is formed by the regular fragmentation of a streak-like primordium. The pattern forming mechanism which subdivides the primordium into individual organs is not capable of adjusting to the variable size of the system. Nevertheless, the number of organs per supraorbital system tends to be held constant. This is achieved by regulating the growth of the system in an appropriate manner.

 Title    Studies on Columnidin Biosynthesis with Flower Extracts from Columnea hybrida  
 Abstract    Columnidin, the characteristic 3-deoxyanthocyanidin of some Columnea species, possesses the 3',4'-B-ring hy-droxylation pattern of luteolinidin and an additional hy-droxyl group at the A-ring, most likely in the 8-position. Studies on substrate specificity of chalcone synthase and flavanone 4-reductase and the demonstration of high flavonoid 3'-hydroxylase activity revealed that the 3'-hy-droxyl group of the B-ring of columnidin is introduced at the flavanone stage by hydroxylation of naringenin to eriodictyol. Enzymatic hydroxylation of the A-ring, how-ever, could neither be observed with soluble enzyme prepa-ration nor with microsomal fraction. Most probably this step first occurs at the anthocyanidin level. Besides flavonoid 3'-hydroxylase the microsomal fraction of Co-lumnea flower extracts contains flavone synthase II activity catalysing desaturation of flavanones to flavones with NADPH as co-factor. The presence of some apigenin, ap-preciable amounts of luteolin and of the 3',4'-hydroxylated flavan-4-ol luteoforol in the flowers confirm the enzymatic data.

 Title    How Different are the Crystal Structures of Chiral and Racemic Diacylphosphatidylethanolamines?  
 Abstract    Both chiral and racemic phosphatidylethanolamines are known to crystallize in a similar poly-morphic form with nearly the same lamellar spacing; yet published lamellar X-ray diffraction intensity data for those materials do not agree with one another, even though the peak positions in Patterson maps are nearly the same. Translational structural searches based on the crystal struc-ture of the racemic compound also lead to similar packing models with both data sets, although the agreement between model and observed data is poor for the chiral compound. A separate analysis of L-DMPE based on lamellar electron diffraction data again leads to a similar lamellar structure with a better agreement between calculated and observed structure factors. The major difference seen for enantiomeric vs. racemic compounds is that, for the racemic lipid, the lateral unit cell spacings are about 3% larger than the chiral form, perhaps indicating a more stable hydrogen bonding network, in agreement with the higher melting point of the racemic compound. Attempts to explain this difference with other head group conformations, however, have not yet produced an improved structural model.

 Abstract    Eriodictyon sessilifolium, Hydrophyllaceae, Glandular Exudate, Benzoic Acid Derivatives, Chromane Eriodictyon sessilifolium, an endemic Hydrophyllaceae of Baja California (Mexico), has been studied for the natural products exuded by glandular trichomes covering its leaves and stems. Major components of this exudate were isolated and identified by spectroscopic methods to be 4-hydroxy-3-(2,3-dihydroxy-3-methylbutyl)-benzoic acid methyl ester (1), the natural methyl es-ter of anodendroic acid (2), and 2,2-dimethyl-3-hydroxychroman-6-carboxylic acid methyl ester (3). Possible biosynthetic relations between these new natural products are considered. In addi-tion, 9 known flavonoid aglycones were identified as exudate constituents.

 Title    On the Volatile Components of Heterotropa takaoi and Related Species (Aristolochiaceae)  
 Abstract    The volatile components of the leaves of four species and five varieties of the section Bicornes of Heterotropa were examined by gas chromatography and gas chromatograph-mass spectro-metry. The analytical results showed that the species of the section contain phenylpropanes, terpenes, and a paraffin as main components. The components have been used to construct phylogenetic trees of the section Bicornes. Despite some discrepancies, the phylogenetic tree obtained for the section seems to be relevant at the tribal revel. Among the species of the section, geographical variation of twelve localities of H. takaoi also were examined and three chemical types (myristicin, safrole, n-pentane-elemicin types) of H. takaoi are distinguished on the basis of their components.

 Title    Biosynthesis of Porphyrinogens in Etiolated Euglena gracilis Z. I. Isolation and Purification of an Endogenous Factor Stimulating the Formation of Porphyrinogens  
 Abstract    A low molecular weight, heat-stable factor has been purified from Euglena gracilis supernatant fraction by employing gel filtration, cation and anion exchange and paper chromatography. This endogenous compound stimulates porphobilinogenase (PBG-ase) (EC 4.3.1.8) activity, an enzyme of the porphyrin biosynthetic pathway. 1CT 7 M folic acid and ICI" 4 M 6-biopterin produced a significant activation, equivalent to 2—4 units of the purified factor. Elution patterns from the columns and fluorescence and UV absorption peaks suggest that this compound is a pteridine. This conclusion is further supported by the fact that both, folic acid and 6-biopterin can replace the action of the isolated factor on PBG-ase. The mechanism of stimula-tion is discussed.

 Title    On the Role of A 1-Piperideine and Tripiperideine in the Biosynthesis of Quinolizidine Alkaloids  
 Abstract    Carbon 14-labelled cadaverine, A 1-piperideine and a-tripiperideine were administered to leaf disks of Lupinuspolyphyllus in short term experiments of 12—20 h duration. Whereas cadaverine was readily incorporated into lupanine in good yields, a 7 to 60 times lower incorporation was observed for tripiperideine or A 1-piperideine. In L. arboreus the incorporation of cadaverine into sparteine was 9 times better than that of A 1-piperideine. These results indicate that A 1-piperideine and tripiperideine are not direct intermediates of lupanine or of sparteine bio-synthesis.
