    Notizen: Abstract (Z,Z,Z)-1,3,6,9-Heneicosatetraene was identified as a sex pheromone component ofEpirrita autumnata (Borkhausen), (Lepidoptera: Geometridae). Gas chromatography coupled with electroantennographic detection revealed one active peak from female pheromone gland extracts. The chemical identification of the compound was based on gas chromatography-mass spectrometry, chemical micro-reactions and unambiguous synthesis. In a field test, a rubber septum loaded with 3000 μg of this compound showed highest attraction of maleE. autumnata moths compared to lower doses and the control. The attraction of males to a 300 μg bait was equivalent to that obtained using live virgin females.

    AFLP markers for the study of rice biodiversity (1998)

    Notizen: Abstract  AFLP was used as a DNA fingerprinting technique in rice (Oryza sativa L.) germplasm analysis. The high efficiency and random coverage of AFLP markers were established. With only five combinations of primers and RFLP anchors, a framework linkage map was constructed. This map demonstrated that the AFLP markers from a limited number of primers were not confined to any particular regions or chromosomes in the rice genome. To analyse the biodiversity of 57 rice germplasm accessions, we examined 179 polymorphic AFLP markers generated from four primer combinations. Both principal component analysis and cluster analysis were used, and three groups were clearly identified which corresponded to genotypes of Isozyme Groups I, II and VI. The number of markers needed for robust classification of rice germplasm and the diversity between/within the groups was established.

    Towards rice genome scanning by map-based AFLP fingerprinting (1999)

    Notizen: Abstract Map-based DNA fingerprinting with AFLP markers provides a fast method for scanning the rice genome. Three hundred AFLP markers identified with ten primer combinations were mapped in two rice populations. The genetic maps were aligned and almost full coverage of the rice genome was obtained. The transferability of AFLP markers between indica × japonica and indica × indica crosses was tested. The chromosomes were divided into DNA Fingerprint Linkage Blocks (DFLBs) defined by specific AFLP markers. Using these blocks, the degree of similarity or divergence within specific chromosome regions was calculated for nine varieties. Applications of map-based fingerprinting for biodiversity studies and maker-assisted selection are discussed.
