PLANT CLONAL LINES AND PLANTS HAVING ELEVATED PEROXIDASE ACTIVITY

摘要

A method for selecting plants and plant tissue cultures that contain elevated levels of peroxidase activity is disclosed. The method uses clonal organogenic tissue culture lines, the cultures being derived from meristematic tissue of a member of the Lamiaceae or Umbelliferae family. Cultured tissue propagules are cultured in the presence of at least one aromatic compound. Those clonal lines exhibiting tolerance to the compound have elevated levels of peroxidase activity.
