From models to ornamentals: how is flower senescence regulated?

  title={From models to ornamentals: how is flower senescence regulated?},
  author={Hilary Rogers},
  journal={Plant Molecular Biology},
Floral senescence involves an ordered set of events coordinated at the plant, flower, organ and cellular level. This review assesses our current understanding of the input signals, signal transduction and cellular processes that regulate petal senescence and cell death. In many species a visible sign of petal senescence is wilting. This is accompanied by remobilization of nutrients from the flower to the developing ovary or to other parts of the plant. In other species, petals abscise while… CONTINUE READING
