Other claims from this paper (9)
- Intervention effect Exogenous ethylene most strongly reduced AtEXPA5 transcription among the tested expansins.
- Intervention effect The ethylene biosynthesis inhibitor 2-Aminoethoxyvinylglycine increased AtEXPA5 transcription.
- Observation The ethylene insensitive ein7 mutant had increased transcription.
- Observation The constitutive ctr1 mutant had decreased transcription.
- Association Hypocotyl elongation followed the same trend as AtEXPA5 expression.
- Intervention effect AtEXPA5 overexpressor 35S-EXPA5 showed reduced hypocotyl length response to exogenous ethylene compared with wild-type and expA5-1.
- Association Aminocyclopropane-1-carboxyl acid showed a dose-dependent effect on hypocotyl elongation.
- Mechanism The authors infer that ethylene endogenously downregulates AtEXPA5 expression.
- Mechanism The authors infer that changes in hypocotyl elongation reflect changes in AtEXPA5 expression.
