| Research Abstract |
During plant organ growth, cells transit from the proliferative phase to the differentiation phase. During cell differentiation, cells cease their growth when they reach their maximum size but the mechanism that determine the final cell size is not known. In this study I investigated the function of plant-specific trihelix transcription factors GTL, DF1 and GT2 in regulating plant cell size. My data demonstrate that plants actively terminate cell growth by upregulating the expression of these transcription factors.
