    Identification of chemicals attractive to the olive bark beetle, Phloeotribus scarabaeoides, in laboratory bioassays (1998)

    Notes: Abstract The semiochemical system of the olive bark beetle Phloeotribus scarabaeoides was investigated. During the course of their life-cycle, whole insects, excised hindguts, frass, wood and leaves were collected, from both the field and from a laboratory rearing system. Samples were analysed by capillary GC/MS, after solvent extraction, collection of air volatiles on a sorbent or solid sample injection. Olfactometer bioassays were used to test the different samples and individual compounds for attraction to both sexes. Decanal, undecanal, 2-decanone, 2-nonanone and 2-undecanone, as well as α- and β-pinene, were identified as attractive compounds.

    CaMADS1, a MADS box gene expressed in the carpel of hazelnut (1998)
    Springer
    Plant molecular biology 38 (1998), S. 1147-1160

    ISSN: 1573-5028
    Keywords: hazelnut ; Corylus avellana ; MADS box genes ; flower development ; ovule ; AGAMOUS

    Topics: Biology
    Notes: Abstract Hazelnut (Corylus avellana L.) is a species of economic interest that shows a peculiar floral biology. Unlike most of the angiosperms, which produce ovules during floral development such that they are ready for pollen at anthesis, hazelnut ovary development is delayed and triggered by compatible pollination. In order to elucidate the mechanisms regulating this unusual process and the role of the MADS box genes in ovary development, a cDNA library from pollinated styles of hazelnut was screened with a mixture of MADS box genes from different plant species. CaMADS1 (Corylus avellana MADS box), a floral-specific MADS box gene, was isolated, and characterized as belonging to the sub-family of the AGAMOUS genes. Northern blot, RT-PCR analyses and in situ hybridization experiments show a precise correlation between ovary development and CaMADS1 expression, indicating a role of this MADS box gene in the processes of floral organogenesis.
