Other claims from this paper (10)
- Association Cellular programmed cell death is tightly connected to petal senescence.
- Mechanism Petal senescence is described as developmental programmed cell death dominated by autophagy and vacuole membrane breakdown.
- Observation Measured markers often characterize petal death as V-PCD or AL-PCD.
- Observation AL-PCD-associated features are often seen alongside V-PCD in early or late senescence.
- Mechanism Both programmed cell death pathways may operate in parallel and be interconnected in senescing petals.
- Mechanism Specific conditions may determine the relative contribution of both pathways to petal cell death.
- Observation The petal cell death cascade may start earlier in parenchyma than epidermis.
- Observation In visibly non-senescent open flowers, many mesophyll cells may have died or disappeared.
- Observation Petal abscission can occur in both non-senescent and senescent petals.
- Association Petal abscission regulation seems independent of petal PCD.
