Title

Hanna Skubatz Botanical studies 2014. doi:10.1186/s40529-014-0068-0
Other claims from this paper (11)
- Observation Sauromatum appendix sections showed two successive temperature rate maxima with three inducers.
- Observation Intact Sauromatum inflorescences also showed two appendix temperature maxima.
- Observation Temperature profiles varied considerably among sections of one Sauromatum appendix in magnitude and peak time.
- Observation After cooling, Sauromatum temperature returned either to its prior baseline or to a slightly different one.
- Intervention effect KCN at 20 mM blocked the temperature rise.
- Intervention effect SHAM at 40 mM blocked the temperature rise.
- Intervention effect KCN and SHAM together blocked the temperature rise.
- Intervention effect DNP at 2.5 mM blocked the temperature rise.
- Intervention effect Thermogenic inducers triggered an appendix temperature rise in Arum.
- Mechanism The authors infer that both cyanide resistant and sensitive pathways are required for heat generation.
- Mechanism The authors suggest variation in temperature profiles may relate to cellular control factors.
