Table 1. Cell Numbers in the Circumference in Root Sections of Wild-Type, jkd, and jkd bib-i Homozygotes.

Genotype		Epidermis	Cortex	Endodermis
Wild type	n = 13	22.9 ± 1.9	8 ± 0	8 ± 0
bib-i	n = 11	22.5 ± 1.2	8 ± 0	8 ± 0
jkd	n = 12	27.5 ± 1.6	9.2 ± 1.0	9.3 ± 1.1
		Layer 1	Layer 2	Layer 3
jkd bib-i	n = 12	40.0 ± 2.9	26.3 ± 1.8	21.3 ± 1.6

In jkd bib-i, cells were counted in the outermost layer at the corresponding position of the epidermis (layer 1) and two layers inward (layers 2 and 3). n represents the number of roots counted; numbers are average and sd.
