The One

Starch-gel electrophoresis of the total livetins of hen's egg yolk resolved 16 zones: seven major zones, six minor zones, and three faint, diffuse zones. One zone was identified with the major component of paper electrophoretic alpha-livetin and hence with serum albumin. Four of the major zones were identified with the major components of paper electrophoretic beta-livetin on the one hand, and with an electrophoretically heterogeneous livetin antigen (livetin antigen 3) on the other hand, thus establishing the electrophoretic heterogeneity and relative immunological homogeneity of the paper electrophoretic beta-livetin fraction. The other two major starch-gel electrophoretic zones were identified as transferrins by their positive staining reaction for iron and comparison of their mobilities with two corresponding serum starch-gel fractions.

A range of laboratory methods was examined for their ability to distinguish between 19 barley cultivars currently grown in Australia. Aleurone colour, revealed after mechanical or chemical dehulling, differentiated Abyssinian, Atlas, Cape and Corvette from the other cultivars. Peroxidase and phenol testing were not useful. Seven different patterns were obtained for the hordeins of lowest mobility by starch gel electrophoresis. Further distinction was provided by flat gel isoelectric focusing of the water-soluble and hordein proteins for which 13 different pattern-groupings were obtained. The two electrophoretic techniques complemented one another, so that the use of both methods left only a few cultivars that could not be distinguished.

Genetic Comparison

Sand fance (Genus Ammodytes) collected from four stations off Japan and one station at Kodiak, Alaska were genetically characterized at 17 protein coding loci using starch-gel electrophoresis. Sand lance in Wakkanai (Cape Soya, Japan) consist of two genetically distinct groups. They are fixed for different alleles at four loci (Ldh-2, -3, G3pdh-2, and Mdhp-2). The genetic structure of one of the groups (Wakkanai-a group, W-a) is similar to that of A. personatus around Japan. The other group (Wakkanai-b group, W-b) has different genetic structure from either A. personatus or the Alaskan collection, which is presumed to belong to A. hexapterus. It is not presently possible to identify the affiliation of the W-b group; however, despite its sympatry with the W-a group, it is reproductively isolated and therefore is probably a distinct species occurring northeast of Hokkaido.

And Migration

Serum transferrins and 11 other genetically controlled proteins representing 17 loci were examined by starch-gel electrophoresis from Siberian, Alaskan, and Canadian populations of Spermophilus parryii. Six transferrin alleles were identified. Arctic populations (S. p. parryii, S. p. osgoodi) were characterized by Tf 6 occurring alone or together with Tf 7 whereas middle and subarctic populations exhibited Tf 7 occurring either alone (S. p. ablusus, S. p. lyratus, S. p. plesius) or together with Tf 5 (S. p. plesius). Tf 8, Tf 9, and Tf 19 constituted local variants. Tf 6 displayed a clinal distribution, increasing in frequency eastward and paralleling a clinal increase in body size. Three PGM2 alleles were observed, the frequencies of which tend to differentiate arctic S. p. parryii from subarctic S. p. ablusus. G6PD-b occurred uniformly in North America and in one Siberian population; a second population (two specimens) exhibited G6PD-a, thereby suggesting that G6PD polymorphism may be present in Siberian S. parryii. The other nine proteins were monomorphic in all Holarctic populations.

Characteristic Zone

Histories were extracted at pH 1.7 from washed nuclei of chicken erythrocytes, spleen, liver, and testis and compared by starch-gel electrophoresis at pH 5.0, ionic strength 0.020. Spleen and liver histories displayed the most complex electrophoretic patterns with 18 zones each and differed only in relative proportions of certain zones. Erythrocyte histone contained a characteristic zone while lacking a group present in spleen and liver histones. Testis histone with only seven zones differed markedly from the other three. These results were consistent with chromatograms of erythrocyte, spleen, and liver histones on sodium IRC-50. The suggested correlation of tissue-specific histones with cell differentiation is discussed.

Spring Leaf

Subterranean clover burrs were collected during summer from 28 sites, 10 of which were in the <500 mm annual rainfall zone. All sites had been sown to the Dwalganup strain, 30-50 years ago. Spaced plants were grown from seed from burr subsamples of each population. Several morphological characters, flowering dates, and oestrogenic isoflavones in late spring leaf samples were determined. At maturity, burr samples were collected from each plant, and the isozyme patterns in seeds were determined for eight enzyme systems using starch gel electrophoresis. Populations from the lower rainfall (< 500 mm) sites usually consisted of one or two strains - Dwalganup with or without Geraldton - and variant (or 'unknown') genotypes were very rare or absent. Populations from the higher rainfall (> 500 mm) sites, on the other hand, comprised about 50% of a few known strains - mostly Dwalganup and/or Dinninup - the remaining 50% consisting of numerous variant genotypes. Infrequent outcrossing between the Dwalganup and Mt Barker strains is the likely major source of this variation. Possible explanations for the lack of variant genotypes in the lower rainfall zone are discussed.

1. The plasma proteins of six inbred strains of mice have been studied, using starch-gel electrophoresis.2. The existence of two alternative plasma transferrin (β-globulin) phenotypes has been demonstrated. Five of the strains have one of these and one strain has the other. Each of the two transferrin patterns comprises three (or possibly only two) electrophoretic bands. The two patterns differ in all of these bands.3. The two transferrin types recognized are determined by a pair of allelic, autosomal genes (designated TrfA and TrfB). The TrfA phenotype (CBA strain) is determined by the genotype TrfA/TrfA, and the TrfB phenotype (A, C57BL, JU, KL, RIII strains) by the genotype TrfB/TrfB. The phenotype TrfAB, of the heterozygote (genotype TrfA/TrfB), is distinguishable and shows four (or possibly only three) bands. In this way it closely resembles a mixture of equal parts of TrfA and TrfB plasma.4. No linkage was detected between the Trf locus and sex, the agouti locus or the haemoglobin locus.5. The possible molecular basis of the action of the transferrin alleles in the mouse, and the widespread distribution in mammals of polymorphism involving the transferrins, are discussed.

The genetic variability in the diploid annual species (2n = 2x = 16) Medicago turbinata L. and M. truncatula Gaernt. was studied at three loci for the enzymes peroxidase, Prx1-1, and leucine-aminopeptidase, Lap1-1 and Lap1-2. Eight accessions of each species, including all the taxonomic forms were surveyed by starch gel electrophoresis. No variation was observed among plants within each accession. Among the M. turbinata forms, four alleles were observed at locus Lap1-2. No variation was detected for the other two loci studied. For the M. truncatula forms, four alleles were found for Prx1-1 and three alleles for Lap1-2. No variation was observed for locus Lap1-1. Form uncinata of M. truncatula, of uncertain taxonomic status, has at least one M. turbinata allele. Both species can be differentiated by their specific allozymes. In general, the alleles of the isozymic loci segregated in a Mendelian fashion in the expected ratios for monomeric enzymes. The presence of chlorophyll-deficient plants on some of the progenies involving different taxonomic forms of the species M. turbinata indicates the presence of isolation barriers between these forms. The lack of segregation at locus Lap1-1 in the tetraploidized interspecific hybrid proves its alloploid nature.

One case of "double albuminemia" has been found among a total number of 70 mule sera tested. This condition was demonstrable by means of paper, agar gel, starch grain, and starch gel electrophoresis. Double albuminemia was shown to be present at pH's 8.6, 11.3, and 12.2. When tested immunochemically, however, these two albumins were alike, and were similar to normal mule serum albumin.

SummaryDifferent fractions of human κ-casein characterized by their sensitivity to chymosin were separated, after reduction, by affinity chromatography on thiol-Sepharose in a 0·1 m-Tris-HCl buffer, pH 7·0, containing 7 M-urea, 0·3 m-NaCl and 1 mm-EDTA. The fraction retained on the column and bearing the SH-groups was then chromatographed on hydroxyapatite in a 5 mm-phosphate buffer, pH 6·8, containing 0·2 m-KC1, 4·5 m-urea and 2 mm 2-mercaptoethanol. The fraction not retained on this column was purified by chromatography on DEAE-cellulose in a 6·6 m-urea, 0·02 m-imidazole, 0·02 m 2-mercaptoethanol buffer, pH 7·0. Two chymosinsensitive fractions were identified by starch-gel electrophoresis at pH 8·6; one of low electrophoretic mobility, the other a smeared band covering the whole distance of migration, in which several bands with mobilities greater than those of β-caseins could be detected.
