Summary
Autophagy, a cellular process, can lead to cell survival or programmed cell death (PCD). This review focuses on autophagic cell death (ACD) mechanisms in plants and their role in stress responses.
Area of Science:
- Plant Biology
- Cellular Biology
- Molecular Biology
Background:
- Autophagy is a conserved catabolic process crucial for cellular homeostasis.
- It degrades cytoplasmic components via autophagosomes fusing with lysosomes.
- While known for stress adaptation, autophagy also mediates programmed cell death (PCD).
Purpose of the Study:
- To review the physiological functions of autophagy.
- To emphasize recently identified mechanisms of autophagic cell death (ACD) in plants.
- To explore the role of ACD in plant stress responses and development.
Main Methods:
- Literature review of autophagy research.
- Focus on studies investigating autophagic cell death (ACD) in plants.
- Analysis of molecular and physiological data related to ACD.
Main Results:
- Autophagy plays a dual role, promoting either cell survival or PCD.
- Specific ACD mechanisms in plants are increasingly being elucidated.
- ACD is implicated in plant development and responses to environmental stress.
Conclusions:
- Autophagy's role extends beyond survival to include programmed cell death.
- Understanding ACD in plants offers insights into plant resilience and development.
- Further research is needed to fully unravel the complexities of ACD in plants.

3.5K
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.

01:30Overview of Cell Death
7.7K
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...

01:27Autophagy
4.6K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:17Phagocytosis of Apoptotic Cells
4.0K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.

11.9K
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...

01:36Delivery Pathways to the Lysosome
7.0K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.

In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...
