Heat stress: an inducer of programmed cell death in Chlorella saccharophila.
Programmed cell death (PCD) has been recognized as a fundamental cellular process conserved in metazoans, plants and yeast. However, the cellular mechanisms leading to PCD have not been fullyExpand

An endopolygalacturonase from Sclerotinia sclerotiorum induces calcium-mediated signaling and programmed cell death in soybean cells.
A basic endopolygalacturonase (PG) isoform, produced early by Sclerotinia sclerotiorum when infecting soybean seedlings, was used to examine the signaling role of the enzyme in aequorin-expressingExpand

Programmed cell death and adaptation: two different types of abiotic stress response in a unicellular chlorophyte.
Eukaryotic microalgae are highly suitable biological indicators of environmental changes because they are exposed to extreme seasonal fluctuations. The biochemical and molecular targets andExpand

Endoplasmic reticulum stress-induced programmed cell death in soybean cells
In animal cells, the endoplasmic reticulum may participate in programmed cell death by sensing and transducing apoptotic signals. In an attempt to analyze the role of the endoplasmic reticulum inExpand

Calcium-mediated perception and defense responses activated in plant cells by metabolite mixtures secreted by the biocontrol fungus Trichoderma atroviride
BackgroundCalcium is commonly involved as intracellular messenger in the transduction by plants of a wide range of biotic stimuli, including signals from pathogenic and symbiotic fungi. TrichodermaExpand

Calreticulin and the Endoplasmic Reticulum in Plant Cell Biology
Calreticulin is ubiquitously expressed in plants. The plant homologue shares with its animal counterpart a similar structural organization and basic functioning. A wide range of developmental andExpand

Silencing of G1-1 and A2-1 genes. Effects on general plant phenotype and on tuber dormancy inSolanum tuberosum L.
SummaryWe have evaluated the effect that the, silencing of two genes specifically expressed in conditions of dormancy (A2-1) and sprouting (G1-1) had on tuber dormancy. For this purpose potato plantsExpand
