Summary
Programmed cell death (PCD) is crucial for organism health, yet its mechanisms in plants remain unclear. This review explores plant PCD in development and disease, comparing it to mammalian apoptosis.
Area of Science:
- Plant biology
- Cellular biology
- Developmental biology
Background:
- Cellular homeostasis relies on regulated cell death.
- Programmed cell death (PCD) is essential for multicellular organisms.
- Understanding of plant PCD lags behind that of mammalian apoptosis.
Purpose of the Study:
- To review the role of PCD in plant development.
- To discuss PCD during plant pathogenesis.
- To compare and contrast plant PCD with mammalian apoptosis.
Main Methods:
- Literature review of existing research on plant PCD.
- Comparative analysis of plant PCD and mammalian apoptosis.
- Discussion of key molecular and physiological aspects.
Main Results:
- PCD plays vital roles in plant development and defense.
- Significant differences exist between plant PCD and mammalian apoptosis.
- Gaps in knowledge regarding plant PCD mechanisms are identified.
Conclusions:
- Programmed cell death is a fundamental process in plants, essential for development and defense.
- Further research is needed to fully elucidate the unique pathways of plant PCD.
- Comparative studies with mammalian apoptosis provide valuable insights but highlight plant-specific features.

01:30Overview of Cell Death
11.4K
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
17.3K
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
7.4K
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
7.2K
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...

5
Cell death is the irreversible loss of cellular structure and function, representing the final stage of severe injury. It plays a key role in both normal physiology and disease.Types of Cell DeathThe two main types are necrosis and apoptosis, though others like necroptosis and pyroptosis also exist.Necrosis:Necrosis is an unregulated form of cell death caused by severe injury such as trauma, toxins, or ischemia. It is characterized by cell swelling, membrane loss, rupture, and leakage of...

01:22Cellular Injury V: Apoptosis and Autophagy
7
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
