e4“proANF-(1-30), proANF-(31-67), and proANF-(79-98) but not ANF (each at < 5.9 pg/ml) significantly increased (P < 0.001) the flow of colored water up stems, coloring their flowers 15-35 min earlier than the other one-half of the same flowers without exogenous peptide addition”
t0“Atrial natriuretic peptides are present throughout the plant kingdom and enhance solute flow in plants”

Other claims from this paper (9)
- Observation Atrial natriuretic factor-like peptides were present in roots, stems, leaves and flower petals of tracheophytes.
- Observation Among the tested tracheophytes, the highest peptide concentrations were ranked from Florida beauty down to Florida coontie.
- Observation Atrial natriuretic peptide-like peptides were also present in Bryophata.
- Observation Atrial natriuretic peptide-like peptides were even present in Euglena.
- Intervention effect Exogenous proANF peptides made flowers color 15-35 min earlier than untreated flowers.
- Intervention effect ANF did not significantly increase the flow of colored water up stems.
- Intervention effect These peptides increased the rate of transpiration.
- Intervention effect These peptides increased the absorption of solutions.
- Method / resource Peptides extracted from plants have elution profiles and molecular weights very similar to pure synthetic peptides.
