Cyclamen persicum (cyclamen) is a commercially valuable, winter-blooming perennial plant. We cloned two cyclamen orthologues of AGAMOUS (AG), CpAG1 and CpAG2, which are mainly expressed in the stamen and carpel, respectively. Cyclamen flowers have 5 petals, but expression of a chimeric repressor of CpAG1 (CpAG1-SRDX) caused stamens to convert into petals,(More)
— In this study, we developed a virtual cycling system (VR Bike) using a magnetorheological fluid brake (MRB). This system consists of a bike, the MRB, a 3-D projector, a screen, a controller and a sound device. Users can drive the bike in virtual worlds with vision, sound, and reaction force on its pedal. We have developed a cylindrical MRB in the previous(More)
