    Notes: Asian cultivated rice was domesticated from the wild rice, Oryza rufipogon and throughout the domestication process, a wide range of morphological and physiological changes altered the ancestral form. This study was conducted to identify the genetic basis of changes associated with the domestication process. An recombinant Inbred line (RIL) population consisting of 120 lines was developed from a cross between the Juponica cultivar.‘Hwayeongbyeo’and a presumed wild progenitor. O. rufipogon Griff. Acc.01944. The population was genotyped with 124 simple sequence length repeat (SSR) markers, providing an average interval size of 15 cM, and also evaluated for 20 traits related to domestication and agricultural performance. A total of 63 quantitative trait locus (QTLs) and one locus associated with qualitative variation for pericarp coloration were identified using single point and composite interval analysis. The number of QTLs per trait ranged from one to seven. Phenotypic variation associated with each QTL ranged from 3.7 to 40.4%. with an average of 15.3%. The results indicated that most domestication-related traits clustered in chromosomal blocks, and the positions of many of these clusters were consistent with those reported in previous studies and with skewed segregation ratios in these BC1,F7 RILs. For 13 (20.6%) of the QTLs identified in this study. the O. rufipogan -derived allele contributed a desirable agronomic effect despite the overall undesirable characteristics of the wild phenotype. Favourable alleles from O. rufipogan were detected for panicle length, spikelets per panicle, days to heading and leaf discoloration associated with cold stress. When compared with previous studies involving interspecific crosses, it can be concluded that O. rufipogon is useful as a source of valuable alleles for rice improvement and that many of the introgressed regions contain genes that have a favourable impact on phenotype in different genetic backgrounds and different environments.

    Storage of Mandarin Oranges II. Effects of Hormones and Wax Coatings (1963)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The effects of temperature, wax emulsion coating, hormone treatment, and their combination on the storage behavior of Nagpur and Darjeeling mandarins were investigated. Use of 2,4-D with wax coating was more effective in prolonging the storage life of both varieties at any storage temperature than either wax coating or 2,4-D used separately. The storage lives of Nagpur and Darjeeling oranges were respectively 50 and 35 days at normal temperature (50–85°F) and 90 and 75 days at 40 ± 1°F when treated with 2,4-D (1000 ppm for Nagpur and 2000 ppm for Darjeeling varieties) followed by wax coating. Wax-coated Nagpur and Darjeeling oranges were in a good marketable condition for 30 and 22 days, respectively, at room temperature, whereas the respective controls remained marketable for only 10 and 7 days. At 40 ± 1°F, storage lives were respectively 60 and 52 days for Nagpur and Darjeeling oranges coated with wax, and 40 and 25 days for their respective controls. Hormone-treated fruits, like the controls, lost their marketable appearance through considerable desiccation, pitting, and shriveling. Loss in weight and spoilage due to fungal attack and rind blemishes were least in fruits treated with 2,4-D followed by wax coating in both varieties and each storage temperature. Pulp-to-peel ratio, reducing sugar, sucrose, total sugar, sugar-to-acid ratio, pH value, and specific gravity in juice increased, whereas vitamin C content and titratable acidity decreased, during storage in all treatments. No off flavor was produced in any case.

    Efficient haploid induction in wheat by using pollen of Imperata cylindrica (2005)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Intergeneric hybridization between wheat (Triticum aestivum L.) and a wild weedy species, Imperata cylindrica (2n = 20) resulted in the recovery of a high frequency of wheat haploids, which were obtained through the elimination of I. cylindrica chromosomes. Cytological analysis of the root tips revealed the somatic chromosome count of the regenerants equalled 21. Haploid regenerants were also obtained in all the crosses of wheat F1s with I. cylindrica, implying the genotype nonspecific nature of wheat x I. cylindrica hybridization. Variation among wheat F1 hybrids was observed with respect to seed formation (44.9-84.5%), embryo formation (15.1-47.7%) and regeneration (27.0-75.0%) in crosses with I. cylindrica. Comparisons based on the efficiency of I. cylindrica and maize (Zea mays) as pollen sources indicated that Imperata-mediated haploid production is equally efficient. There is natural coincidence of flowering period of I. cylindrica with that of wheat under sub-temperate conditions which is advantageous compared with maize, which cannot be grown during the winter season in the sub-temperate regions.

    Effect of Soybean Varieties and Growing Locations on the Flavor of Soymilk (2005)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 70 (2005), S. 0

    Notes: : The volatile compounds of soymilk prepared from 5 soybean varieties grown in 2 locations were isolated and separated by a dynamic headspace analyzer and capillary gas chromatography. The coefficient of variation for the quantitative analysis of volatile compounds of soymilk by dynamic headspace analysis was less than 3.0%. Soybean varieties and growing locations had significant effects on the volatile compounds of the batches of soymilk at α= 0.05. The higher the soybean protein, the higher was the volatile compounds of soymilk. Correlation coefficient between the protein content and the volatile compounds of the milk was 0.99. Thirty-eight volatile compounds of soymilk were identified by a combination of mass spectrometry and gas chromatographic retention times of standard compounds. Most of the identified compounds were formed by the lipid oxidation of soymilk. However, 2-pentylfuran, dimethyl disulfide, and dimethyl sulfide were formed by singlet oxygen. The beany or green flavor that makes the soymilk unpleasant or unacceptable to Westerners may be due to 2-pentylfuran, which is formed from linoleic acid by singlet oxygen. The beany flavor can be eliminated by processing the soymilk with a minimum exposure to light and air.

    Variation in the Cellular Slime Mold Acrasis rosea (1961)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 8 (1961), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: A number of isolates of the cellular slime mold, Acrasis rosea, differed from each other in the range of microorganisms on which they could grow and fruit. In a test for the possible occurrence of sexual reproduction and genetic recombination, two of the most widely divergent of these physiological races were studied further. Mixed colonies were obtained in agar plate cultures of Rhodotorula mucilaginosa, a yeast utilized by both. When spores from mature fruiting bodies or amoebae migrating out from the mixed colonies were isolated singly, regrown on Rhodotorula, and tested on a critical spectrum of food microorganisms, about 3-4% proved to be distinct from the original two strains. Although some of these new types remained stable for several transfers, they eventually reverted to one or both of the parental types. The possibilities of explaining the neotypes on the basis of diploidy, heterokaryosis, or mixed cytoplasmic effects are discussed. The occurrence of cell anastomoses and occasional binucleate cells favors the latter two possibilities.

    Effect of Aminotriazole and Streptomycin on Multiplication and Pigment Production of Photosynthetic Microorganisms (1960)
    Oxford, UK : Blackwell Publishing Ltd

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: 3-Amino-l,2,4-triazole (AT) stops multiplication of the photosynthetic protists, Ochromonas danica, O. mal-hamensis, Euglena gracilis var. bacillaris. and Rhodopseudo-monas palustris; it also stops growth of the multicellular plant, Spirodela oligorhiza. O. danica and S. oligorhiza are the most sensitive. AT is about equally inhibitory to algal flagellates grown in the light or dark. Porphyrin biosynthesis is suggested as the probable site of inhibition by AT. Both AT and streptomycin (SM) bleach all the above organisms. Bleaching is permanent only in SM-bleached E. gracilis; all the other organisms become fully pigmented when placed in inhibitor-free media. The uniqueness of the SM-bkaching of E. gracilis is discussed.

    Notes: In view of the paucity of information on the effect of grassland irrigation on livestock production, a grazing experiment was made in 1960 and 1961 in which the response to irrigation was measured at two dairy-cow stocking rates. The method and herbage results are described.The increases in herbage utilized as a result of irrigation were comparable with the results of cutting experiments, averaging 342 lb of ash-free organic matter per acre-inch of water used. Irrigation also increased the uniformity of herbage production.
