Whether or not there will be a significant drought induced die-back even of pine is debatable (cf. Dobbertin et al. 2007).
For both vegetation types, we evaluated four disturbance types: undisturbed, controlled burns, drought- and beetle-induced die-off, and prescriptive thinning treatments.
Large-scale, rapid reductions in forest and woodland tree cover caused by fire, drought-induced die-off, or wildfire-mitigating thinning prescriptions, all three of which differentially affect canopy structure, are increasingly altering coniferous-dominated landscapes across extensive regions such as western USA.
Furthermore, many of the cells in which CA was induced may have died, precluding their quantitation.
By contrast, in embryos in which cells had been induced to die, CED-4 assumed a perinuclear localization.
While doing her Ph.D., Wang came across a defense mechanism in plants involving apoptosis, where "the plant cell is induced to die around the infection site so the pathogen cannot be spread to other tissues," Wang says.
We examined the effect of expressing each of the seven SIRT proteins in healthy cerebellar granule neurons (CGNs) or in neurons induced to die by low potassium (LK) treatment.
It was a paradox, since the toxic antibiotic, BS, was able to rescue the murine keratinocyte BALB/MK induced to die by the apparently inoffensive bacterial bsrm gene.
This switch between K15 acetylation and S14 phosphorylation on H2B was also observed in apoptotic thymocytes from animals treated in vivo with glucocorticoids and in a rat hepatoma cell line (HTC) induced to die by UV-C or Fas ligand.
Induction of FLAG-RIPK3 by 4HT also failed to kill the cells, but when TNF was added to cells in which FLAG-RIPK3 had been induced, they died.
Anyway, these neuroprotective effects could be still sufficient in vivo to rescue neurons of the ischemic penumbra from secondary death induced by dying cells in the infarct core.
