Example sentences for: senescence

How can you use “senescence” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • It is important to mention that our experiments were conducted at similar passage levels (passage 6 to 8) in both groups, since senescence of fibroblasts is associated with a shift from the biosynthesis of PGI 2 to TXA 2 [ 24 25 ] . It is possible that the difference seen in our study between HF-IPF and HF-NL could result from comparing fibroblasts of different ages.

  • These include DNA damage caused by Ionizing Radiation and genotoxic agents [ 1], by expression of activated oncogenes such as ras or myc [ 2], or during progression of primary cells to senescence [ 3].

  • The WRKY transcription factors are involved in defense, wounding, senescence and plant development [ 7 16 70 71 72 73 ] . There are 70 genes with a WRKY domain in the Arabidopsis genome and six of them (WRKY15, 25, 33, 46, 62, 70) are in the stress cDNA collection.

  • This enzyme has several proposed functions, such as gluco-neogenesis in germinating seeds, carbon recovery during senescence, nitrogen assimilation during seed development and decarboxylation of OAA in PEPCK-type C4 photosynthesis [ 36, 37].

  • We used ozone as an abiotic stressor because the plant's response at the biochemical and molecular level shows extensive overlap with the pathogen defense response and includes the production of ROS, as well as induction of HR and SAR [ 23 24 ] . At the phenotypic level, acute ozone exposure (high dose for a short interval) causes necrotic lesions similar to those caused by avirulent pathogen infections, whereas chronic ozone exposure (low dose for an extended period of time) accelerates foliar senescence, producing similar symptoms to those caused by virulent pathogen infections [ 25 26 ] . There is evidence that elicitor-evoked ROS production, called the oxidative burst, is an essential signaling component of the defense response [ 27 ] . Moreover ozone is a component of photochemical smog and itself represents an oxidative stress to living organisms, damaging crops and forests [ 28 ] .
