Other claims from this paper (12)
- Intervention effect The CYP98A3 insertion inhibits development and cell growth.
- Observation Insertion-mutant lignin content is reduced.
- Observation Insertion-mutant stem lignin consists essentially of p-hydroxyphenyl units with trace guaiacyl and syringyl units.
- Observation Roots show ectopic lignification and a substantial proportion of guaiacyl and syringyl units.
- Mechanism The root lignin composition suggests a CYP98A3-independent meta-hydroxylation mechanism.
- Observation Mutant plantlets produce very low sinapoyl ester amounts relative to control.
- Observation Mutant plantlets accumulate flavonol glycosides.
- Association Reduced cell growth correlates with altered cell-wall polysaccharide abundance, particularly decreased crystalline cellulose.
- Association Reduced cell growth correlates with profound changes in gene expression and homeostasis reminiscent of stress.
- Observation CYP98A3 cosuppressed lines show a gradation of developmental defects.
- Observation Foliar sinapoyl esters in cosuppressed lines resemble control.
- Association Purple leaf color correlates with sinapoylated anthocyanin accumulation.
