Table 5. Analysis of cell division and cell size in tmk mutant leaves.

Genotype	Size of the6^th leaf (cm²)	Size of adaxialmature epidermalpavement cells (µm²)	Frequency of cellsshowing Cyc1At:GUSactivity
Wild type	3.04±0.28	1431±412	4.3%±0.6%
tmk1;tmk4	0.28±0.08*	1212±376*	1.2%±0.4%*

Wild-type plants were compared with various tmk mutant combinations. Adaxial epidermal pavement cells were measured in 20 plants for each genotype. The average±standard deviation is shown. Values that are significantly different (p<0.01) from wild type are labeled with an asterisk. The frequency of cells showing Cyc1At:GUS was determined by number of adaxial epidermal pavement cells stained with Cyc1At:GUS/total number of adaxial epidermal pavement cells. ND: not determined.
