Cell wall composition is altered in ARP2/3 mutants. (A–F) Cell wall was isolated from 4-d-old etiolated hypocotyls (A, C, E) and 6-week-old inflorescence stems (B, D, F), and the composition of the cell wall was analysed. The cellulose content is not changed in hypocotyls (A), but decreased in mature inflorescence stems in ARP2/3 mutants, with statistically significant decreases for arp2 and arpc4 mutants (B). Similarly, cellulose/hemicellulose ratio is not changed in hypocotyls (C), but decreased in mature inflorescence stems, with statistically significant increases for arpc4 and arpc5 (D). Galacturonic acid (GalA) content in ammonium oxalate fraction enriched in homogalacturonan (HG) is not changed in hypocotyls (E), but is increased in mature inflorescence stems, with statistically significant increases for arpc4 and arpc5 (F). *P <0.05, **P < 0.01. AIR: alcohol-insoluble residue.
