    Topics: Biology
    Notes: Abstract Iso-electric focusing of extracts derived from stigmatic homogenates of Brassica oleracea reveals that the mature stigma possesses large quantities of a glycoprotein not present in earlier stages of development in the bud. Pollen germination experiments carried out in parallel with the biochemical tests suggest that the appearance of this glycoprotein, which has an isoelectric point of pH 5.8, is coincident with the development of the self-incompatibility response. The site of this protein, and the role it may play in pollen-stigma interactions are discussed in terms of current models of the self-incompatibility system in Brassica.

    Notes: Abstract Three parameters are described for estimating the natural occurrence of chemically defined insect pheromones: (1) the rate and duration of release by the insect, (2) the density of the pheromone-emitting insect population in both time and space, and (3) dispersal and degradation rates of the chemicals. Each of these parameters, except dispersal, was estimated for a population ofDendroctonus brevicomis LeC, and its three component attractive pheromones. A single generation of 610,000 beetles, believed to comprise the entire population in a 65-km2 forest, was estimated to have released 0.78, 3.7, and 370.5 g of frontalin,exo-brevicomin, and myrcene, respectively, within a 30-day period.

    Notes: Abstract Western pine beetles were caught on unbaited sticky traps placed near a source ofexo-brevicomin, frontalin, and myrcene. Size of trap, distance and direction from the source of attractant, and height from the ground were varied. Significant differences in trap catch were observed in relation to each of the variables. Traps close to the source of attractant caught more beetles than traps farther from the source. Traps downwind of the source of attractant caught more beetles than did upwind traps. More males than females were trapped close to the source of attractant.

    Notes: Abstract Authentic 4,6,6-lineatin (3,3,7-trimethyl-2,9-dioxatricyclo-[3.3.1.04,7]nonane) (I) was produced in low yield via three synthetic pathways. In field tests, microgram amounts of the product from all three syntheses attracted large numbers ofTrypodendron lineatum of both sexes. These results confirm that 4,6,6-lineatin (I) is a population aggregation pheromone forT. lineatum.

    Pollen-pistil interaction in Brassica oleracea (1979)
    Springer
    Planta 146 (1979), S. 211-216

    ISSN: 1432-2048
    Keywords: Brassica ; Pollen adhesion ; Pollen hydration ; Self-incompatibility ; Tryphine mobility
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Quantitative studies of the adhesion of pollen grains to the stigma in Brassica oleracea revealed that self-pollen is initially less firmly bound than cross-pollen. The pollen grain tryphine, believed to be important in the adhesion process, has been shown to differ in mobility following self- and cross-pollination when observed using fluorescent probes. The hydration of the pollen grains has been investigated in vitro by measuring the changes in shape, volume and fresh weight of the imbibing grains. Whilst little change in volume could be detected there was a considerable increase in fresh weight together with a change of shape. The significance of these events, which occur prior to pollen germination, is discussed in relation to their effect upon subsequent germination and expression of self-incompatibility.

    Specificity of trail markers of forest and eastern tent caterpillars (1979)

    ISSN: 1573-1561
    Keywords: Lepidoptera ; Lasiocampidae ; Malacosoma americanum ; Malacosoma disstria ; Tortricidae ; Archips cerasivoranus ; trail marker ; pheromone ; interspecific response ; tent caterpillar

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Exploratory trails deposited on paper strips by the forest tent caterpillar (FTC),Malacosoma disstria Hubner, and the eastern tent caterpillar (ETC),M. americanum (Fabricius), as well as extracts of these trails, readily elicited interspecific trail-following behavior. In 2-choice tests involving simple Y mazes constructed from these paper strips, the caterpillars of both species preferred by approximately 3∶1 the trails of the FTC. Studies involving whole colonies of the ETC maintained under nearnatural conditions in the laboratory, however, indicated that the trails deposited by successful foragers of the ETC as they returned to their tent from feeding sites were more attractive than the exploratory trails of either the ETC or FTC. The pronounced interspecific response of these congeners to each other's trails suggests that they utilize either qualitatively similar or identical trail-marking chemicals. Both species preferred their own trails to those ofArchips cerasivoranus (Fitch) (Tortricidae), providing the first evidence that more distantly related lepidopterous larvae utilize distinct trails.

    Interactions of S alleles in sporophytically controlled self incompatibility of Brassica (1979)
    Springer
    Theoretical and applied genetics 54 (1979), S. 193-201 
    Details
    ISSN: 1432-2242
    Keywords: Incompatibility ; Cabbage ; S Alleles ; Dominance ; Brassica

    Notes: Summary The expressed activity in pollen and stigma was determined for both S alleles of sixteen S-alíele heterozygous genotypes and for one of the two S alleles of two additional heterozygotes. Activities were measured using pollen tube penetration and seed set data from reciprocal crosses between each S-allele heterozygote and its two corresponding S-allele homozygotes. In pollen the S-allele activities ranged from zero to 100% inhibition of pollen tube penetration and seed set, and in the stigma they ranged from 8 to 100% inhibition. Of the sixty-eight S-allele activities measured, thirty-three (48%) were 90 to 100% inhibition, nine (13%) were 80 to 89% inhibition and one to five were within each ten-unit range below 80% inhibition. In an S-allele heterozygote, each subset of two S alleles had an activity for each allele in both pollen and stigma which was highly repeatable among duplicate pollinations within and among successive years. Each subset of two S alleles had a specific S-allele interaction in the pollen, and the same or another specific interaction in the stigma. In pairings with six other S alleles, allele S 2 had four calculated levels of activity in pollen that ranged from 88 to 94%, and five levels in the stigmas between 15 and 94%. When paired in a heterozygote, alleles S 3 and S 5 had activities ranging between 42 and 59%, representing mutual weakening of S-allele activity. Also, heterozygote S 15 S 3 had pollen activities, respectively, of 25 and 6%, i.e. mutual weakening in the pollen. These results indicate that in heterozygous combination with a series of other S alleles, each S-allele may have activity in pollen and also in stigma that potentially is between zero and 100% inhibition. They further indicate that the defined sexual-organ X S-allele-interaction Types I, II, III and IV are extremes; all intermediate variations including complete weakening of both alleles are possible. Recessiveness is weakening of the activity of but one of the two S alleles. The pollen tube penetrations into the style and seed set were highly correlated.

    Procedures for identifying S-allele genotypes of Brassica (1979)
    Springer
    Theoretical and applied genetics 54 (1979), S. 249-265

    ISSN: 1432-2242
    Keywords: Brassica ; S alleles ; Incompatibility ; Hybrid ; Crucifer ; Dominance

    Topics: Biology
    Notes: Summary Procedures are described for efficient selection of: (1) homozygous and heterozygous S-allele genotypes; (2) homozygous inbreds with the strong self- and sib-incompatibility required for effective seed production of single-cross F1 hybrids; (3) heterozygous genotypes with the high self- and sib-incompatibility required for effective seed production of 3- and 4-way hybrids. From reciprocal crosses between two first generation inbred (I1) plants there are three potential results: both crosses are incompatible; one is incompatible and the other compatible; and both are compatible. Incompatibility of both crosses is useful information only when combined with data from other reciprocal crosses. Each compatible cross, depending on whether its reciprocal is incompatible or compatible, dictates alternative reasoning and additional reciprocal crosses for efficiently and simultaneously identifying: (A) the S-allele genotype of all individual I1 plants, and (B) the expressions of dominance or codominance in pollen and stigma (sexual organs) of an S-allele heterozygous genotype. Reciprocal crosses provide the only efficient means of identifying S-allele genotypes and also the sexual-organ x S-allele-interaction types. Fluorescent microscope assay of pollen tube penetration into the style facilitates quantitation within 24–48 hours of incompatibility and compatibility of the reciprocal crosses. A procedure for quantitating the reciprocal difference is described that maximizes informational content of the data about interactions between S alleles in pollen and stigma of the S-allele-heterozygous genotype. Use of the non-inbred Io generation parent as a ‘known’ heterozygous S-allele genotype in crosses with its first generation selfed (I1) progeny usually reduces at least 7 fold the effort required for achieving objectives 1, 2, and 3, compared to the method of making reciprocal crosses only among I1 plants. Identifying the heterozygous and both homozygous S-allele genotypes during the I1 generation facilitates, during subsequent inbred generations, strong selection for or against modifier genes that influence the intensity of self- and sib-incompatibility. Selection for strong self and sib incompatibility can be effective for both homozygous inbreds and also for the S-allele heterozygote, thus facilitating production of single-cross F1 hybrids and also of 3-and 4-way hybrids.
