Other claims from this paper (15)
- Observation Daylily flowers are insensitive to ethylene.
- Intervention effect Exogenous ABA prematurely induces loss of differential membrane permeability in daylily petals.
- Intervention effect Exogenous ABA prematurely increases lipid peroxidation in daylily petals.
- Intervention effect Exogenous ABA prematurely induces proteinase and RNase activities in daylily petals.
- Method / resource Six daylily genes increasing during senescence were isolated.
- Observation The six DSA genes belong to multigene families.
- Observation Homology suggests DSA3 belongs to the cytochrome P450 superfamily.
- Observation Homology suggests DSA5 may be a water stress protein.
- Observation Homology suggests DSA6 is a putative S-1 type nuclease.
- Observation Homology suggests DSA12 resembles impedance induced protein.
- Observation Homology suggests DSA15 is a fatty acid elongase.
- Intervention effect ABA accelerates accumulation of DSA mRNAs except DSA4 by 3.2 to 43 times.
- Observation DSA mRNA levels in leaves are less than 4% of the petal maximum.
- Observation DSA mRNA levels in leaves do not change significantly during senescence.
- Observation DSAs except DSA12 are expressed at low levels in daylily roots.
