Summary
Programmed cell death (PCD) in plants shares mechanisms with animal apoptosis, but distinct features exist. This review compares plant phytaspases and animal caspases, highlighting similarities and differences in PCD implementation.
Area of Science:
- Plant biology
- Cellular biology
- Biochemistry
Background:
- Programmed cell death (PCD) is a fundamental biological process.
- PCD occurs in both plants and animals, with distinct evolutionary paths.
- Understanding PCD mechanisms is crucial for various biological processes.
Purpose of the Study:
- To review modern concepts of programmed cell death (PCD) in plants.
- To compare PCD mechanisms and participants in plants versus animals.
- To elucidate commonalities and differences in PCD implementation.
Main Methods:
- Comparative analysis of scientific literature.
- Review of molecular mechanisms of PCD.
- Focus on proteolytic enzymes (caspases and phytaspases).
Main Results:
- Programmed cell death (PCD) in plants shares fundamental similarities with animal apoptosis.
- Key differences exist in the specific molecular players and regulation of PCD between plants and animals.
- Plant phytaspases and animal caspases represent distinct but functionally analogous enzyme families.
Conclusions:
- PCD is a conserved but diversely implemented process across kingdoms.
- Comparative studies of plant and animal PCD offer insights into evolutionary strategies.
- Further research into phytaspases and plant-specific PCD pathways is warranted.

01:30Overview of Cell Death
8.2K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

01:30Apoptosis
12.5K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

01:16Necrosis
5.2K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

01:25Cell Signaling in Plants
5.9K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

01:18Autophagic Cell Death
3.7K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

01:17The Extrinsic Apoptotic Pathway
6.9K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
