    [Auszug] A hyperdiploid line of Lettre's Ehrlich ascites tumour of mouse (ELD) served as the starting material. Adult as well as new-born mice were used as host animals. The tumour was transplanted into the adult mice by injecting more than 107 cells. The new-born mice, which were not more than 48 h old, ...

    [Auszug] The alga, at first, occupies the intercellular spaces in the nodules (Fig. 1, 2) and gradually invades the cellular region, forming globose to subglobose colonies (Fig. 1,1). The trichomes are few-celled, though many occur as individual cells. The characteristic blue-green pigment, double-walled ...

    Notes:
    Summary An efficient culture system has been developed for repeated cycles of somatic embryogenesis in microspore-derived embryos of Brassica juncea without a callus phase. Haploid embryos produced through anther culture showed a high propensity for direct production of somatic embryos in response to 2 mgL−1 BA and 0.1 mgL−1 NAA. The embryogenic cultures which comprised the elongated embryonal axis of microspore-derived embryos when explanted and grown on the medium of same composition produced a large number of secondary embryos. These somatic embryos in turn underwent axis elongation and produced more somatic embryos when explanted and cultured. This cycle of repetitive somatic embryogenesis continued with undiminished vigour passage after passage and was monitored for more than a year. Somatic embryos from any passage when isolated at cotyledonary stage and grown on auxin-free medium for 5 days and then on a medium containing NAA (0.1 mgL−1), developed into complete plants with a profuse root system and were easily established in the soil. The cytology of the root tips of these plants confirmed their haploid nature. The total absence of callus phase makes the system ideal for continuous cloning of androgenic lines, Agrobacterium-mediated transformation and mutation induction studies.

    Notes:
    Summary Callus cultures of four Sorghum bicolor (L.) Moench cultivars were initiated from aseptically germinated seed. Prior to culture on media containing 0, 100, 200, and 400 μM aluminum, the callus had been subcultured for 3 to 12 months. There were differences amongst the cultivars in response to the aluminum in terms of callus growth. Growth was inhibited at the highest level of aluminum tested. Subculture of callus from aluminum selection medium on both aluminum-containing and aluminum-free media indicated that aluminum-selected callus grew better in the presence of aluminum. Plants were regenerated from only one cultivar (IS3620C of the Margaritiferum group) after several passages on aluminum-supplemented media. Regeneration capacity was however inhibited at 400 μM aluminum.

    Summary 1. The length of the chromosome complements of T. monococcum, Ae. speltoides var. ligustica and Ae. squarrosa, the donors of the A, B and D genomes respectively of T. aestivum, varied in the ratio 1.0 ∶ 1.24 ∶ 0.76. The proportion of the total lengths of the chromosomes belonging to the A, B and D genomes in the bread wheat variety Chinese Spring, as calculated from the data of Sears (1954), also falls into a similar ratio (1.0 ∶ 1.28 ∶ 0.84). 2. T. monococcum, T. dicoccum and T. aestivum differed in the proportion 1.0 ∶ 1.5 ∶ 2.0 as regards chromosome length and not as 1.0 ∶ 2.24 ∶ 3. 0 as would be expected from the additive value of the total chromosome length of the concerned genome donors. 3. The DNA content of individual nuclei in the species studied varied in proportion to chromosome length, thus indicating that the DNA content per unit length of chromosome is constant in the material studied. 4. The type of karyotype asymmetry in the different Triticum and Aegilops species was classified according to the scheme of Stebbins (1958). The diploid species had the most symmetrical and the hexaploids, the most asymmetrical karyotype. No prominent heterochromatic segment could be detected in any of the species. 5. The data indicate that a considerable degree of elimination of chromosomal material has taken place in tetraploid and hexaploid wheats subsequent to their origin. It is suggested that this might have been an important factor in the conversion of tetraploid and hexaploid wheats into functional diploids. A combination of the multivalent gene suppressor system and chromosome elimination appears to have led to a synthesis of the advantageous features of auto- and allo-polyploidy in tetraploid and hexaploid wheats.

    Notes:
    Summary Hybridization followed by continuous selection of lines of barley from different cross-combinations involving high protein-high lysine genotypes and the agronomically superior strains resulted in breaking the negative correlations between 1000 grain weight and high protein content and high DBC values. The methodology of DBC-Kjeldahl protein adopted in the present study is likely to be useful in identifying high lysine lines. The present study has shown considerable variability with respect to protein content and grain weight and has provided interesting genotypes which can be used in synthesising lines with improved nutritional quality and productivity in barley. The success in breaking the undesirable linkages to factors that impair the endosperm development is due to sufficient genetic variability in the initial breeding material as well as the use of suitable breeding procedures like the full-sib mating in the early segregating generations.

    Notes:
    Summary Protoplasts isolated enzymatically from precultured cotyledonary leaves ofB. oleracea var.botrytis and cultured in KM8p medium (Kao andMichayluk 1975) underwent sustained divisions in about 0.1% population to eventually produce callus, whereas mesophyll protoplasts from either field grown orin vitro raised plants failed to divide. The callus readily differentiated on Murashige-Skoog medium as modified for shoot culture (Binding 1974) to give rise to shoot and roots.

    Abstract Sorghum bicolor (L.) Moench, plants were regenerated from 4 to 5 month old callus cultures originally derived from seedling explants. Somaclonal variation was examined in the SC2 and SC3 generations of eight different clones plus the non-tissue cultured parent line. Characters examined included the area of the third leaf, height, tiller number, total shoot weight, seed number, grain yield, days to flowering, and chlorophyll content in the SC2 generation. Some plants were phenotypically different from the parent line in the SC2 generation. All clones were similar to the parent in third leaf area and chlorophyll content. Three clones had significant height reduction and six had significantly higher total plant matter production. Seven of the clones had significant increases in number of secondary tillers, and all had significant decreases in days to flowering. Only three clones had significant increases in grain yield and seed number; however, all the clones had smaller seeds. In subsequent studies of SC2 and SC3 generations of three somaclones, characters examined included height, tiller number, total shoot weight, and days to flower. In one of the somaclones none of the original differences in characters was maintained in two subsequent growing seasons in the SC2 or SC3 generation. The other two somaclones maintained the increased tiller number in the next growing season in both the SC2 and SC3 generations. In one of the somaclones plant height reduction occurred in the SC2 and SC3 generations. All other traits were not maintained.
