How can you use “pcd” in a sentence? Here are some example sentences to help you improve your vocabulary:
However, we have argued on the basis of results with ndr1 mutant plants that HR "triggering" in response to the avrRpt2 / RPS2 combination is weaker than that in response to avrB / RPM1 [ 4 ] . Weaker "triggering" results in a lower probability of individual cells undergoing PCD early in the HR, prior to the onset of potentiation caused by increased SA levels [ 4 12 ] . Signaling elicited by avrRpt2 clearly differs in many respects from that directed by the other avr genes.
Fas and FasL are expressed in the TM and a FAS-stimulating monoclonal antibody causes PCD of TM cells [ 29, 30].
15d-PGJ 2 , 15-deoxy-delta 12, 14-PGJ 2 ; AP-1, activator protein-1; ERK, p42/44, Extracellular signal-Regulated Kinase; LDL, low density lipoprotein; MAP kinases, Mitogen-Activated Protein kinases; MTT (3-(4,5-dimethylthiazole-2yl)-2,5-diphenyltetrazolium bromide); PCD, programmed cell death; PPARs, peroxisome proliferator-activated receptors; SAPK/JNK, Stress-Activated Protein Kinase/ c-Jun NH2-terminal Kinase.
The HR occurs in response to infection with avirulent bacteria at levels of inoculum that cause a large percentage of leaf cells to undergo programmed cell death (PCD) [ 8 ] . In contrast to results with avrRpt2, P. syringae bacteria carrying the avirulence genes avrB , avrRpm1 , avrPphB or avrRps4 elicit an exaggerated HR relative to that on the wild-type Columbia parent [ 5 7 ] . In a study in which bacteria carrying avrB were chosen as a representative member of this class, in further contrast to results with avrRpt2 , these bacteria were capable of eliciting SAR and PR-1 induction on ndr1-1 mutant plants [ 4 ] .
This plasmid, called pCD1 [ 1 ] in Y. pestis , encodes for a type III secretion apparatus necessary for the translocation of effector proteins (Yops) into eukaryotic target cells [ 2 ] . The net result of this polarized toxin translocation is the disruption of eukaryotic cell signalling and structure [ 2 ] . Induction of the virulence-related genes on pCD1 is linked to an in vitro phenomenon termed the Low Calcium Response (LCR).
