Cos'è la senescenza
Cellular senescence is a phenomenon characterized by the cessation of cell division. In their experiments during the early 1960s, Leonard Hayflick and Paul Moorhead found that normal human fetal fibroblasts in culture reach a maximum of approximately 50 cell population doublings before becoming senescent. This process is known as "replicative senescence", or the Hayflick limit. Hayflick's d… Webgradiente auxinico, in corrispondenza al decorso della senescenza, viene perturbato inducendo la sintesi di etilene. Infine, nella fase di caduta, la concentrazione di etilene inducono le cellule dello strato di abscissione alla produzione di cellulasi ed enzimi degradativi di parete, determinando così la caduta della foglia.
