Other claims from this paper (12)
- Mechanism Recessive mutations at three loci caused collapse of mature Arabidopsis xylem cells.
- Association The irx lines had up to an eightfold reduction in stem cellulose.
- Intervention effect The mutations did not change cell-wall phenolic amounts.
- Intervention effect The mutations did not change cell-wall polysaccharide amounts.
- Mechanism Reduced cellulose changed the spatial organization of wall material in irx lines.
- Mechanism Normal cellulose deposition may be required to assemble lignin or polysaccharides.
- Mechanism Reduced cellulose content decreased stem stiffness.
- Mechanism The authors infer that irx walls fail to resist compressive forces.
- Mechanism Cellulose may be needed to develop normal lignin structure.
- Observation irx plants grew slightly more slowly and were shorter.
- Observation irx plants were otherwise normal in appearance.
- Recommendation The authors expect irx mutations to help identify control factors for cell-wall synthesis and deposition.
