    Notes: Abstract For the infinite dihedral double group D * ∞ and the finite dihedral double groups D 2 * through D 6 * ; D 8 * ; D 10 * ; and D 12 * , we present various choices of standard unitary irreducible matrix representations and discuss properties of corresponding 3-Γ symbols. The presentation follows a recent exposition of the general theory of 3-Γ symbols and coupling coefficients [1] and a companion description of general features of double groups and their irreps and 3-Γ symbols [2].

    Notes: Abstract It is demonstrated that for the group-subgroup hierarchy I *⊃ C 5 * , one may choose standard irreducible matrix representations and corresponding all-real sets of 3-Γ symbols which obey a formalism just as elegant as the classical one for the 3-j symbols of the rotation double group. The 3-Γ symbols are phase-fixed by the specification of basis functions (or, equivalently, subduction coefficients) generating them and based on functions first given by McLellan. Other icosahedral double-group hierarchies are also briefly discussed.

    Notes: Summary A rice mutant with unique protein expression/ transport properties has been established as cells in liquid suspension and partially characterized. Mutants were originally recovered from anther calli grown for three cycles at inhibitory levels of lysine + threonine and one cycle of S-(2-aminoethyl)cysteine. Cell suspension cultures were started from high lysine-containing seeds regenerated from the inhibitor selections. Cultures of the mutant produce 2 times as much protein per unit weight as is produced by the control. Significant portions of the proteins are exported from the cells into the surrounding medium. The mutant also has 20% greater lysine content in the exported protein than the control. This cell suspension line should be particularly useful for biochemical and molecular studies on protein synthesis and processing phenomena in cereals.

    Notes: Abstract We present sets of real 3-Γ symbols which correspond to explicitly given irreducible matrix representations for the two double group hierarchies T* ⊃ C 3 * and T* ⊃ C 2 * . They fit into the formalism exposed in a previous paper [1] on the general theory of 3-Γ symbols and coupling coefficients and illustrate much of the discussion in a subsequent one [2] treating the particular properties of the double groups.

    Notes: Abstract For all the subgroup hierarchies descending from the octahedral double group O *, we have obtained sets of 3-Γ symbols and discuss here their properties. We have entirely real sets of 3-Γ symbols for the tetrahedral and tetragonal hierarchies as well as for O * ⊃ C 3 * . For the latter hierarchy and the tetragonal ones, formalisms almost as powerful as the classical one for the rotation group may be established. We also discuss results obtained for cases with strict adaption to D 3 * where it is now known that non-real 3-Γ symbols are unavoidable. The 3-Γ symbols are phase-fixed by the specification of basis functions (or, equivalently, subduction coefficients) generating them. The significance of the concept of associated representations of O* is discussed. The problems raised by the two multiplicity triples UT1U and UT2U in O* are given particular attention.

    Modification of amino acid composition of endosperm proteins from in-vitro-selected high lysine mutants in rice (1990)

    Notes: Summary Endosperm protein mutants in rice may be recovered by biochemical selections with inhibitory levels of lysine and threonine. Among the phenotypes recovered from in vitro selections are lines with increased protein and percent lysine in the protein. This work was designed to identify changes in proteins of rice mutants and to further our understanding of the mechanisms of lysine plus threonine selections in rice. Among the most obvious amino acid changes in mutants was a higher lysine level in all protein solubility fractions and a decrease in tyrosine. Methionine and glutamate are reduced in some protein fractions. However, methionine is significantly higher in the mutant than the control in the glutelin fraction. Several other aspartate pathway amino acids are higher in the mutant than the unselected controls. Separation of proteins in SDS-PAGE gels showed shifts in the protein profiles in the mutants, including a decrease in the major 30 kDa low lysine globulin component, and an increase in several high-molecular-weight components, approximately 60–100 kDa. Increases in the lysine content of proteins of different solubility classes and different proteins within classes are detailed.

    Free and bound amino acids and proteins in developing grains of rice with enhanced lysine/proteins (1997)

    Notes: Abstract  Free amino acids were determined in developing seed of a rice mutant with enhanced grain lysine. This phenotype frequently has enhanced protein. Some free amino acids of developing seed are inversely related to the level of total amino acids in proteins of the mature grain. Amino acids that were enhanced in protein, including aspartic acid, threonine, methionine and lysine, were notably lower in the free amino-acid pool. Our conclusion is that mutant-developing grains process aspartate amino acids more rapidly than the controls. Conversely, arginine, valine and glutamic acid/glutamine accumulate as free amino acids with mutant/control ratios of 1.39, 1.29 and 1.12, respectively. Glutamic acid/glutamine in proteins of mature seeds is lower in the mutant than the control. 3H-lysine incorporation showed enhanced isotope incorporation into at least four proteins. One mutant protein was less actively labelled than analogous controls. The 3Hlysine pattern indicates processing modifications in this useful rice mutant.

    Notes: In recent years air quality and atmospheric investigations have become very important topics. This results from a new legal basis for environmental protection which generates the need for the accurate measurement of ambient conditions. Despite the importance of these investigations, detailed reviews characterizing the existing analytical GC systems are scarce. The author has attempted to remedy this unsatisfactory situation by presenting a comprative review of the principal commercially available systems as well as some homemade set-ups. No single method will be optimal for all purposes. The system of choice will depend on the particular application and on the quality and composition of the sample. This review does not attempt to cover all existing systems, but some exotic or lesser known systems have also been included.

    Notes: Carbon-13NMR data recorded in the pulsed Fourier transform mode are re- ported for 1- and 2-naphthyltrimethyl- stannanes and 9-phenanthryltrimethyl- stannane. Assignments of ring carbon resonances are based on magnitudes of tin-carbon spin-spin coupling constants, substituent chemical shifts, spin-lattice relaxation times and proton coupled spectra.
