PGP1 and PGP19 regulate the division of endodermal cells. A, Visualization of fluorescent signals in PGP1::PGP1-GFP (PGP1-GFP) and PGP19::PGP19-GFP (PGP19-GFP) plants, and their high resolution images (right). Ep, epidermis; Co, cortex; En, endodermis; P, pericycle. B, Transverse sections of WT and pgp1pgp19 double mutant roots grown in 1/2 MS solid media for 7 d. Asterisks on the images indicate endodermal cells. C, Quantification of the number of endodermal cells in these plants (n > 22). En and Co indicate the endodermis and cortex, respectively. Error bars represent sd, and the asterisk indicates a statistically significant difference from the control (P < 0.01, two-tailed t test). Scale bars = 20 μm.
