• Hyoscyamus
  • To recognize the different cell and tissue type in which alkaloids biosynthesis occurs, various studies like study of enzymes, gene transcripts, and immumo-cytochemical studies (see, Immunocytochemistry ) have been carried out in model plants like Atropha belladonna, Catarahthus roseus, Eupatorium cannabinum, Hyoscyamus muticus, Senecio jacoba and S. vernalis .

  • roots
  • In Senecio species, pyrrolizidine alkaloids are produced in actively growing roots as senecione N-oxides, which are transported via the phloem to above ground organs. (wordpress.com)
