Do Fungi Undergo Apoptosis-Like Programmed Cell Death?

Abstract:
This question of whether fungi undergo apoptosis-like programmed cell death can be separated into two questions. One question is about applying the term "apoptosis" to fungi, and the other is a more challenging question of whether fungi have evolved mechanisms that inflict self-injury. The answers to both questions depend on the definitions applied to "apoptosis" and "programmed cell death." Considering how these and other cell death terms originated and are currently defined for animals, some confusion arises when the terms are applied to fungi. While it is difficult to defend the concept of fungal apoptosis, the more interesting issue is whether fungi will eventually be found to encode programmed or extemporaneous self-destructive processes, as suggested by intriguing new findings.
Insights
Fungi may not undergo apoptosis, but research suggests they might possess self-destructive processes. Further investigation into fungal programmed cell death mechanisms is warranted.
Area of Science:
- Mycology
- Cell Biology
- Biochemistry
Background:
- The application of animal-centric cell death terminology to fungi is debated.
- Definitions of apoptosis and programmed cell death are crucial for understanding fungal cell demise.
Purpose of the Study:
- To clarify whether fungi exhibit apoptosis-like programmed cell death.
- To explore the existence of self-injurious mechanisms in fungi.
Main Methods:
- Comparative analysis of cell death definitions.
- Review of existing literature on fungal cell death.
Main Results:
- The term "apoptosis" is difficult to apply directly to fungi.
- Evidence suggests fungi may have evolved distinct self-destructive processes.
Conclusions:
- Fungal apoptosis is questionable based on current definitions.
- Further research is needed to identify programmed or extemporaneous self-destruction in fungi.

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...
