Title
Auxin Asymmetry during Gravitropism by Tomato Hypocotyls
Marcia A. Harrison; Barbara G. Pickard PLANT PHYSIOLOGY 1989. doi:10.1104/pp.89.2.652
Other claims from this paper (6)
- Observation Lower-side to upper-side auxin ratio was about 1.4 after 5–10 minutes.
- Observation The auxin asymmetry ratio increased to about 2.5 after 20–25 minutes.
- Observation The auxin asymmetry ratio reached 3.5 during main curvature.
- Observation The lower-to-upper side elongation ratio was about 3.9.
- Intervention effect An auxin asymmetry ratio of 2.5 accompanied wrong-way curvature after high auxin application.
- Mechanism Auxin asymmetry was judged sufficient to account for the start of curvature.
