0 the fact of becoming older, and therefore being in less good condition and less able to function well:
Senescence refers to gradual deterioration with age and in animals is typically very obvious under zoo conditions.
These findings rule out potential site-specific differences in leaf senescence and turnover rate.
In some cases they also had delayed senescence and fewer green leaves below the ear.
Alternatively, stimulated microglia undergo senescence, demonstrated by reduced viability and mitotic activity, after several weeks in culture and in the absence of telomerase repression.
In summary, multiple studies have now shown the strong correlation between the formation of heterochromatin and the attainment and maintenance of the senescence phenotype.
The obvious answer - death - is inadequate, for death is the inevitable and unavoidable conclusion of senescence.
The influence of sward condition on rates of herbage growth and senescence in mixed swards under continuous stocking management.
Our current knowledge of lung senescence is incomplete and much of it is based on detailed anatomical studies reported in the 1950s and 60s.
It goes without saying that when plasmid transfer rates overshadow plasmidinduced senescence death, the senescent type can invade.
