Abstract excerpt

BACKGROUND: Accurate cell cycle progression is essential for plant growth and development. UVI4(UV-B-insensitive 4) and its homologue OSD1(Omission of the Second Division) function as negative regulators of the anaphase-promoting complex/cyclosome (APC/C) and are critical for cell cycle regulation in plants. In potato, UVI4 and OSD1 have a single homologue, StOSD1/UVI4, and the role of one copy of this gene in...
