Steviol glycosides (SGs) are noncaloric natural sweeteners found in the leaves of stevia (). These diterpene glycosides are biosynthesized by attaching varying numbers of monosaccharides, primarily glucose, to steviol aglycone. Rebaudioside (Reb) D and Reb M are highly glucosylated SGs that are valued for their superior sweetness and organoleptic properties, yet they are present in limited quantities in stevia leaves.

Here, we analyzed the role of the B1 subclass of mitotic cyclins in cell cycle control during Arabidopsis development. While we reveal CYCB1;5 to be a pseudogene, the remaining four members were found to be expressed in dividing cells.
