1. This would allow direct measurement of how far senescence in the original population had been caused by accumulation of partially recessive mutations.

2. Senescence of clones is probably caused by the accumulation of deleterious mutations.

3. It was comfortable with its premature senescence but at the same time was wired with a wildness and youthful energy.

4. An even later flight to assess late senescence of the cereal crops might be undertaken this year.

5. Tea can inhibit cell senescence, people live longer.

6. It affects tuberization, leaf senescence, and dormancy.

7. Cytokinin is an important phytohormone involved in delaying senescence of plant leaf,(http://sentencedict.com/senescence.html) and isopentenyl transferase (IPT) gene encodes the key enzyme that catalyzes cytokinin biosynthesis.

8. Like cell proliferation, differentiation and apoptosis, cellular senescence is a fundamental feature of normal cells.

9. Senescence and immortalization: role of telomeres and telomerase - Carcinogenesis, 2005.

10. The presence of leaf senescence is a result of metabolism disadjustment in active oxygen and free radicals inside the body.

11. The role of serine endopeptidase in cu-cumber leaf senescence was studied by using the inhibitor of serine endopeptidase and plant growth regulators(6-BA and ABA)on darkness-induced cucumber leaves.

12. These results suggested that flesh lignification was a senescence phenomenon in postharvest loquat fruits, and inappropriate chilling storage will promote the incidence of flesh lignification.

13. The effects of 1-MCP treatments on senescence and quality of snap bean during storage were investigated.

14. The increase in firmness during postharvest loquat fruit senescence showed similar characteristic to tissue lignification of chilling injury, however, the mechanism might be different.

15. And exogenous Spermine could retard drought-sensitive Variety senescence better than drought-resistant one under water stress.

16. This is rather a trivial example: if teeth were the only problem, senescence could be cured by false teeth.

17. Water deficit stress-induced changes of endopeptidase activity and types and acceleration of flower senescence process in cut rose (Rosa hybrida) (Chinese with English Abstract).

18. Under condition of field cultivation, winter wheat Yumai 49 were sprayed with GA3, NBT, 6-BA, TIBA, PP333 to study their effect on process of flag leaf senescence and yield constituents.

19. Expression of an oncogene in a primary cell can, paradoxically, block proliferation by inducing senescence or apoptosis through pathways that remain to be elucidated.

20. Spraying cytokinin on waterlogged plants may stop the decrease of chlorophyl content and delay senescence.

21. Soluble protein, DNA, and RNA contents in flag leaf of cultivar senescence at early stage rapidly reduced and the activities of protease and nuclease rapidly raised.

22. He refers to this approach as strategies for engineered negligible senescence ( SENS ).

23. Conclusion: EEP can enhance mouses immunity and delay mouse senescence.

24. Besides, chlorophyll content, soluble protein, thylakoid membrane lipids fatty acid instauration and activity of Violaxanthin de-epoxidase(VDE)were all decreased with the progress of senescence.

25. The burst out of reactive oxygen may activate the process of senescence.

26. We observed the influence of aging or caloric restriction (CR) on pancreatic beta cell senescence and its insulin secretion.

27. Thus, if ethrel is applied too early, it may affect the fullness of maturing cotton bolls due to pre- cedable senescence of cotton leaves.

28. Telomere and telomerase are the focus of modern biological study. There are close relationships among telomere loss and cell ageing, activation of telomerase, cell senescence and immortalization.

29. "Our method allowed us to look at the consequences of removing senescent cells at different stages of the mouse life cycle, " van Deursen says. "We didn't just block senescence altogether."

30. POA and POF may, therefore, represent a continuum in phenotypical expression of different etiologies of premature ovarian senescence.
