(1) The degradation of proteins and the remobilization of amino acids to developing tissues is a prominent process during senescence .(2) We have devised a functional approach to clone genes involved in the regulation of cell growth and senescence .(3) Although it is characterized as being a deterioration process, senescence is considered to be a highly evolved genetic process.(4) Mortality barriers to human cell immortalization and effectors of replicative cellular senescence in human cells(5) A pretreatment of cold-induction temperatures had little effect on the course of tissue senescence under these conditions.(6) But most healthy mammalian cells managed just a few dozen divisions before they stopped, a process known as replicative senescence .(7) Additional carbon would also be released into the rhizosphere with border cell senescence and death.(8) Oxidative processes during senescence involve an increase in enzyme activities generating oxygen radicals and superoxide ions.(9) Behind this zone of environmental invasion is a wave of cell senescence , death and necrotrophic disappearance.(10) The terms senescence and programmed cell death have led to some confusion.(11) For leaf and stem samples, mature but not senescent tissues were taken.(12) Fourth, after some 30 passages, cells cultured at 33u00b0C stopped proliferating, suggesting a senescent state.(13) A feature shared by senescent cells in culture and in vivo is shortening of the telomeres.(14) It is known that induction of telomere shortening leads to the extinction of yeast clones similar to a senescent phenotype.(15) The molecular mechanisms for vacuolar protein degradation and the nutrient recycling pathway in senescent leaves are generally not clear.
