title: A Phalaenopsis variety with floral organs showing C class homeotic transformation and its revertant may enable Phalaenopsis as a potential molecular genetic material.
abstract: The Orchidaceae is one of the most famous garden plants, and improvement of the orchid is very important in horticulture field. However, molecular information is largely unknown. We found a Phalaenopsis variety harboring floral organs showing C class homeotic change. Column is composed of the anthers with the receptive stigmatic surface just underneath them in wild type. However the C class variety produced column with sepal or petal like structure at the abaxial side. This is the typical abnormality as C class mutants in plants. Further, wild type looking revertant was found from the meristem tissue cultured population. This result strongly indicates the existence of active transposable element in Phalaenopsis genome. This transposon may enable Phalaenopsis as a good material for molecular genetic analysis in Orchidaceae.
