    Notizen: Abstract A biolistic particle delivery system was used to genetically transform embryogenic tissue of Pinus radiata. The introduced DNA contained a uidA reporter gene under the control of either the tandem CaMV 35S or the artificial Emu promoter, and the npt II selectable marker controlled by the CaMV 35S promoter. The average number of stable, geneticin-resistant lines recovered was 0.5 per 200 mg fresh weight bombarded tissue. Expression of the uidA reporter gene was detected histochemically and fluorimetrically in transformed embryogenic tissue and in derived mature somatic embryos and regenerated plants. The integration of uidA and npt II genes into the Pinus radiata genome was demonstrated using PCR amplification of the inserts and Southern hybridisation analysis. The expression of both genes in transformed tissue was confirmed by Northern hybridisation analysis. More than 150 transgenic Pinus radiata plants were produced from 20 independent transformation experiments with four different embryogenic clones.

    Notizen: Abstract A series of chloroplast and nuclear probes were used to examine restriction fragment length polymorphisms (RFLPs) in kiwifruit (Actinidia deliciosa) and three of its closest relatives. The four species fell into two pairs, withA. chinensis andA. deliciosa closely related but some distance away from the other two species,A. latifolia andA. eriantha. The results are consistent with the hypothesis that the diploid species,A. chinensis, is a precursor ofA. deliciosa, which is hexaploid.
