    Notes: Self-incompatibility is one of the most effective approaches to utilizing heterosis in oilseed rape around the world. To evaluate the heterosis of double low self-incompatibility, the possibility of combining seed yield and oil content, and the genetic effects of parents on their hybrid progenies, a 2-year field trial using a 3 × 22 NC II mating design was conducted during the 1999-2001 growing seasons in Wuhan, China. Significant differences in seed yield per plant and seed oil content were observed among the F1 hybrids and between F1 progenies and their parents. However, the heterosis for seed yield per plant was much greater than that for seed oil content. Mid-parent heterosis and high-parent heterosis of seed yield per plant ranged from 5.50 to 64.11% and from –2.81 to 46.02%, while those of seed oil content ranged from –1.55 to 7.44% and –3.61 to 6.55%, respectively. Non-additive genetic effects were a major mechanism that accounted for the yield heterosis in addition to additive effects. In contrast, seed oil content heterosis was mainly dependent on an additive genetic effect. General combining ability (GCA) determined the stability of hybrid cultivars. In hybrid breeding, parental materials might be selected by the sum of GCAs and variances of special combining abilities (SCAs) of female and male parents for traits affected by both additive and non-additive effects, and by the sum of GCAs of two parents for traits controlled mainly by additive effects. Primary branches and their siliques were the most important yield traits.

    Notes: An ultrahigh density seeding process of diamond thin-film deposition is demonstrated. Diamond powders with average grain sizes of 0.038 and 0.101 μm were used to study the surface roughness as a function of deposition time, film thickness, and nucleation density. The diamond films, prepared by hot filament chemical vapor deposition, were characterized by atomic force microscopy, scanning electron microscopy, and Raman spectroscopy. An extremely high nucleation density on the order of 1011 cm−2 was achieved by coating 0.038 μm diamond powder on the surface of the Si substrate. One micron thick films were obtained with the mean surface roughness of 30 nm. © 1995 American Institute of Physics.

    Notes: Rs1046AB is a genic male sterile two-type line in rapeseed that has great potential for hybrid seed production. The sterility of this line is conditioned by the interaction of two genes, i.e. the dominant genic male sterility gene (Ms) and the suppressor gene (Rf). The present study was undertaken to identify DNA markers for the Ms locus in a BC1 population developed from a cross between a male-sterile plant in Rs1046AB and the fertile canola-type cultivar ‘Samourai’. Bulked segregant analysis was performed using the amplified fragment length polymorphism (AFLP) methodology. From the survey of 480 AFLP primer combinations, five AFLP markers (P10M13350, P13M8400, P6M6410, E7M1230 and E3M15100) tightly linked to the target gene were identified. Two of them, E3M15100 and P6M6410, located the closest, at either side of Ms at a distance of 3.7 and 5.9 cM, respectively. The Ms locus was subsequently mapped on linkage group LG10 in the map developed in this laboratory, adding two additional markers weakly linked to it. This suite of markers will be valuable in designing a marker-assisted genic male sterility three-line breeding programme.

    Notes: The commercial utilization of heterosis in seed yield by means of hybrid varieties is of great importance for increasing oilseed rape production in China. This requires a functional system for the production of hybrid seed. The Brassica napus oilseed rape line 9012AB is a recessive epistatic genic male sterility (GMS) two-type line, in which the sterility is controlled by two pairs of recessive duplicate sterile genes (ms1 and ms2) interacting with one pair of a recessive epistatic inhibitor gene (rf). Homozygosity at the rf locus (rfrf) inhibits the expression of the recessive male sterility trait in homozygous ms1ms1ms2ms2 plants. This study was conducted to identify molecular markers for one of the male fertility/sterility loci in the B. napus male sterility line 9012AB. Sterile bulk (BS) and fertile bulk (BF) DNA samples prepared from male sterile and male fertile plants of the homozygous two-type line 9012AB were subjected to amplified fragment length polymorphic (AFLP) analysis. A total of 256 primer combinations were used and seven markers tightly linked to one recessive genic male sterile gene (ms) were identified. Among them, six fragments co-segregated with the target gene in the tested population, and the other one had a genetic distance of 4.3 cM. The markers identified in this study will greatly enhance the utilization of recessive GMS for the production of hybrid seed in B. napus oilseed rape in China.

    Notes: Reciprocal hybridization between four self-incompatible lines of Brassica napus: 271, 181, 184 and ‘White Flower’, revealed incompatibility. The reciprocal F1s obtained by bud pollination showed self-incompatible reactions, and no segregation for self-incompatibility was observed in all the reciprocal F2 populations, indicating that lines 271, 181, 184 and ‘White Flower’ were genetically identical with regard to self-incompatibility. Observations of self-incompatibility in 17 hybrids from crosses between line 271 and 17 varieties of B. napus showed 10 of the F1 hybrids to be self-compatible, while four were partially self-compatible and three were self-incompatible. Genetic analysis based on F2 and BC1 populations from five self-compatible F1 hybrids and two self-incompatible F1 hybrids suggested the existence of at least two loci controlling the self-incompatibility of line 271: one is the S locus, with dominant and recessive relationships between the S alleles, and the other is the suppressor (sp) of the S locus. The sp locus is genetically different from the S locus, and also shows dominant and recessive relationships between the sp alleles.

    Notes: Five restorers of ‘polima’ cytoplasmic male sterility (pol CMS) cannot restore the fertility in dominant genie male sterility (DGMS). A dominant male sterility gene from both, a DGMS line Rs l046AB and DGMS hybrid ‘Zhongza No. 3’, was successfully introduced into Polima cytoplasm. A random-mating population of pol CMS restorers was established by using many double-low pol CMS restorers as pollinators to cross continuously to the DGMS plants which had Polima cytoplasm.

    Notes: We have proposed that the transmembrane receptor encoded by the c-Kit protooncogene and its ligand play an important role in regulating the proliferation of blasts cells in acute myeloblastic leukemia (AML). To test this hypothesis, immunobeads were used to separate blasts from three Kit-expression positive cell lines into strongly Kit-protein positive and weakly Kit-protein positive fractions. The strongly positive fraction had greater proliferative potential than the weakly positive fraction as assessed both by colony-formation in methylcellulose and growth of clonogenic cells in suspension. The reproducibility of the percentage of each blast population found in the strongly and weakly positive fractions provided evidence that Kit-protein expression is regulated. Kinetic experiments provided evidence for reversible transitions between strong and weak Kit protein expression. Thus regulated expression of the Kit receptor may be a mechanism for controlling blast cell growth in culture. © 1993 Wiley-Liss, Inc.

    Hydrocortisone in culture protects the blast cells in acute myeloblastic leukemia from the lethal effects of cytosine arabinoside (1991)

    Notes: The blast cells in acute myeloblastic leukemia (AML) respond to many of the same regulatory mechanisms that control normal hemopoiesis. These include the growth factors that bind to membrane receptors and steroid hormones or vitamins that have intracellular receptors. We report the effects in culture of the steroid glucocorticoid hydrocortisone on freshly explanted AML blasts from patients and on two continuous AML cell lines. Only small changes in clonogenic cell numbers in suspension cultures were seen in the presence of hydrocortisone. The most striking effect of the hormone was on the sensitivity of blasts cells to cytosine arabinoside (ara-C). In contrast to the response of AML blast cells to retinoic acid, a ligand for intracellular steroid receptors that sensitizes some blast populations to ara-C, hydrocortisone reduced the toxic effects of the drug. The protective action of hydrocortisone was not mediated through the cell cycle since exposure of blasts to hydrocortisone did not affect the percentage of cells in DNA synthesis as measured with the tritlated thymidine (3HTdR) “suicide” technique. The hydrocortisone effect could be demonstrated using a pulse (20 min) exposure protocol. Blasts pulsed with increasing specific activities of 3HTdR showed the usual response pattern with an initial loss in plating efficiency to about 50% of control, followed by a plateau, regardless of whether the cells had been exposed to hydrocortisone. Control blasts exposed to increasing ara-C concentrations gave very similar dose-response curves; in striking contrast, blast cells cultured in hydrocortisone, then pulsed with ara-C did not lose colony-forming ability even though the same population was sensitive to 3HTdR. The hydrocortisone effect was dose and time related; protection from ara-C increased from 10-8 to 10-5 M and was seen after 4 hr exposure but required 8 hr to reach a maximum. We conclude that hydrocortisone can protect blasts from the lethal effects of ara-C even while the cells are in active DNA synthesis.
