Characterization of three pxc1 mutants. (A) Location of insertions creating pxc1 mutant alleles. The location of the insertion site is indicated. Lines indicate non-coding sequence and boxes indicate coding sequence; (B) mRNA expression levels in pxc1-1, pxc2-1, and pxc1-3 plants were determined by the real-time PCR. EF1α were used as an internal control; (C)pxc1-1 and pxc1-3 mutant plants are pendent in phenotype under short-day conditions. Photographs of wild-type (Col0) are on the left and those of pxc1-3 are on the right. Arabidopsis plants taken 51 days after germination (DAG); (D-L) Phloroglucinol staining for lignin in the cross-sections taken from the base of 30 cm wild-type (D-F), pxc1-1(G-I), and pxc1-3(J-L). Scale bars represent 100 μm in f, i, l close-up.
