V. Chesnokov, R. Manteuffel] Abstract : The influence of kanamycin on the percentage of pollen germination and on tube growth of pollen from non-transformed and transformed plants of various species containing a chimaeric kanamycin resistance gene (NPTII) was investigated. Pollen grains isolated from kanamycin resistant plants expressed resistance when germinating in vitro, whereas kanamycin impaired tube growth of pollen from non-transformed plants. Pollen grains from transgenic plants were less sensitive and produced significantly longer tubes. mRNAs of the chimaeric gene are probably presynthesized concurrently with the other mRNAs during microsporogenesis, and kanamycin resistance is expressed by mRNA translation during pollen tube elongation.
