In mammals protein tyrosine phosphorylation plays an important role in the activation of apoptosis. However, tyrosine phosphorylation associated with cell death has not been examined in plants. We monitored changes in tyrosine phosphorylation during cell death in rice (Oryza sativa L.) suspension cultures. Cell death was induced in the cell cultures by mannose treatment or by allowing the cultures to senescence. We have demonstrated that both mannose and senescence induced DNA fragmentation in… 

Effects of iron excess on cell viability and mitogen-activated protein kinase activation in rice roots

Investigating the signal transduction pathway activated by increasing concentrations of iron showed that iron elicited a remarkable myelin basic protein (MBP) kinase activity, and suggested that the MAPK, reactive oxygen species, protein phosphatase, and H+-ATPase might function in the plant iron-triggered signaling pathway in rice roots.

Zinc-induced Cell Death in Rice (Oryza Sativa L.) Roots

Results suggest that the ROS, protein phosphatase and PI-3K may function in the Zn-induced cellular toxicity in rice roots.

Protein phosphorylation differs significantly among ontogenetic phases in Malus seedlings

Protein phosphorylation varied significantly during vegetative phase change and floral transition in apple seedlings, and most of the observed changes were consistent among seedlings and between hybrid populations.

Protein and Metabolite Analysis Reveals Permanent Induction of Stress Defense and Cell Regeneration Processes in a Tobacco Cell Suspension Culture

The secretome of a tobacco cell suspension culture was investigated by a combined proteomic and metabolomic approach and showed strong abundance of stress associated proteins and metabolites in the absence of elicitors or additional stress treatments.

Identification and functional characterization of a leucine-rich repeat receptor-like kinase gene that is involved in regulation of soybean leaf senescence

The cloning and characterization of a soybean receptor-like kinase (RLK) gene, designated GmSARK, and results strongly suggested the involvement of this LRR-RLK in regulation of soybean leaf senescence, maybe via regulating chloroplast development and chlorophyll accumulation.

Identifying sucrose as a signal for nitrate uptake by wheat roots

Some sugars supplied directly to roots can stimulate nitrate uptake by wheat (Triticum aestivum L.) roots. To identify a signaling molecule, we compared the response of net nitrate influx to sugar

Induced inaccessibility and accessibility in the oat powdery mildew system: insights gained from use of metabolic inhibitors and silicon nutrition.

Induced inaccessibility in oat to Blumeria graminis requires active cell processes that are reiterative de novo cell processes involved in inherent penetration resistance and may well involve cellular memory of the initial attack.

Mannose inhibition of nitrate uptake by wheat roots

The inhibition of mannose on nitrate uptake is not due to the onset of programmed cell death because it starts too rapidly and it is reversible, however, it is probably due to Pi and consequent ATP depletion.



Regulation of intestinal tyrosine phosphorylation and programmed cell death by peroxovanadate.

The data suggest that tyrosine kinase inactivation or tyosine phosphatase activation may initiate intestinal epithelial cell death, and peroxovanadate enhanced protein tyrosines phosphorylation of many intestinal proteins, dramatically increasing the dually phosphorylated and active form of mitogen-activated protein kinase.

Protein-tyrosine phosphorylation regulates apoptosis in human eosinophils and neutrophils.

It is demonstrated that the effect of GM-CSF on granulocyte cell death can be blocked by the tyrosine kinase inhibitor genistein, suggesting that increases in tyrosin phosphorylation are essential to inhibit cell death.

Tyrosine phosphorylation in DNA damage and cell death in hypoxic injury to LLC-PK1 cells.

The data provide a strong evidence that tyrosine phosphorylation plays as important role in DNA damage and cell death in chemical hypoxic injury to renal tubular epithelial cells.

Expression of Oryza sativa MAP kinase gene is developmentally regulated and stress-responsive.

Results suggest that this OsMAPK2 may function in the stress-signalling pathway as well as panicle development in rice.

Multiple levels of tobacco WIPK activation during the induction of cell death by fungal elicitins.

The kinetics of WIPK activation following elicitin treatment correlated with the onset of hypersensitive response (HR)-like cell death and staurosporine and K-252a, two Ser/Thr protein kinase inhibitors that blocked WIPk activation, suppressed cell death.

Programmed cell death during rice leaf senescence is nonapoptotic.

The cellular events associated with programmed cell death during leaf senescence in rice (Oryza sativa) plants are reported here and are quite different from features characteristic of apoptosis in animals.

A programmed cell death pathway activated in carrot cells cultured at low cell density

These findings show that plants, like animals, can control PCD by social signaling, and imply that the mechanism of PCD in plants and animals may be similar.

Serine/threonine protein kinases and apoptosis.

This minireview will focus on the role of protein kinases in apoptosis, which has been implicated both in the upstream induction phase of apoptosis and in the downstream execution stage, as the direct targets for caspases.

Chemical-induced apoptotic cell death in tomato cells: involvement of caspase-like proteases

Results showed that proteolysis plays a crucial role in apoptosis in plants, and caspase-specific peptide inhibitors were found to be potent inhibitors of the chemical-induced cell death in tomato cells, indicating that, as in animal systems, casp enzyme-like proteases are involved in the apoptotic cell death pathway in plants.
