Abstract

Pseudomonas cichorii causes necrotic leaf spots (NLS), while Pseudomonas syringae pv. tabaci induces a hypersensitive response (HR) in eggplant. P. cichorii induced cell death at 9 h after inoculation (HAI), reaching a maximum of around 24-30 HAI. On the other hand, cell death was induced 6 HAI with P. syringae pv. tabaci, reaching a maximum of around 12-18 HAI. Superoxide generation was observed in eggplant inoculated with both bacteria. DNA fragmentation, cytochrome c release into the cytosol and expression of defense-related genes such as PR-1 and hsr203J was also induced by inoculation with both bacteria, but these plant reactions were more rapidly induced in eggplant inoculated with P. syringae pv. tabaci rather than those with P. cichorii. Lipid peroxidation and induction of lipoxygenase (LOX) was drastically induced in eggplant inoculated with P. syringae pv. tabaci compared to P. cichorii-inoculated eggplant. Pharmacological studies showed that induction of the cell death, and the NLS or the HR in response to both bacteria was commonly associated with de novo protein synthesis, reactive oxygen species and caspase III-like protease. Interestingly, involvement of lipid peroxidation, LOX, serine protease, and DNase differe...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.
