Research Abstract |
I have previously identified and reported a "bulb", a complex and mobile structure on the continuous vacuolar membrane at 2002. To get a clue its biological significance and function, I searched mutants that show abnormalities in bulbs. By a reverse genetical approach, I found that the frequency of the appearance of bulbs were reduced in autophagy mutants. I further tried to isolate mutants that have abnormal bulbs by forward genetical approach.
