Outline of Final Research Achievements

In order to understand the molecular mechanism of the orchid-specific floral organs such as lip, column, pollinium, we established the cultivation system and Agrobacterium-mediated transformation system in Psygmorchis pusilla. We also analyzed the optimal condition for mutant generation with ion beam and EMS. cDNA fragments related to floral development were isolated from Psygmorchis pusilla and Habenaria radiata.
