    Notes: Summary Field studies ofPolyrhachis moesta revealed that colonies were facultatively founded by more than one queen, even though each established colony was inhabited by only one queen with her workers. In pleometrotic colonies, it was found that cofoundresses frequently exhibited cooperative behaviors, including trophallaxis. The results of DNA fingerprinting showed that multiple foundresses were not genetically to one another. It seems that they aggregate randomly and independently of their relatedness. A discussion of the reasons why foundresses ofP. moesta do not aggregate preferentially with genetically related females.

    Notes: Abstract  Aseptically propagated regenerates were cultivated in a hydroponic apparatus, a phytotron or in the field, and their growth and littorine contents were investigated. No littorine was detected in aseptic regenerates cultured on solidified Murashige and Skoog medium, nor was it found in leaves under the three conditions tested. In roots, it was common features to all three conditions tested that littorine increased dramatically after transplantation from culture tubes and was a major alkaloid up to week 4; subsequently the littorine contents varied depending on the cultivation conditions. Roots cultivated in the field showed a marked thickening and rapid disappearance of littorine; those cultivated in the hydroponic apparatus were thin and maintained a high level of littorine for a long time. In a plant cultivated for 16 weeks in a pot, littorine content in the roots decreased with increasing root diameter.

    Notes: Abstract A hairy root clone (M8) of Atropa belladonna, producing high levels of tropane alkaloids, was established by transformation with Agrobacterium rhizogenes (MAFF 03-01724). Littorine, an intermediate of tropane alkaloids, was detected by high-performance liquid chromatography and gas chromatography-mass spectrometry in the alkaloid fraction of the hairy roots and identified by nuclear magnetic resonance analysis. Littorine was also detected in the non-transformed root culture of A. belladonna.

    Notes: Abstract Hairy roots of Coleus forskohlii were induced by infection with the Agrobacterium rhizogenes MAFF 03-01724 strain. Growth and forskolin production of two hairy root clones cultured in various liquid media were examined. Hairy root clone B9 grew well in woody plant liquid medium and showed a high forskolin yield (ca. 1.3 mg/ 100 ml flask) after 5 weeks of culture. The time course of growth and forskolin production of the clone B9 cultured in woody plant liquid medium was also examined. Rapid growth started at week 2 and continued until week 5. The highest forskolin yield (ca. 1.6 mg/100 ml flask) was obtained at week 5. Productivity was much higher than that previously reported.
