Summary
Ferroptosis, an iron-dependent cell death, was observed in plants after heat shock. This suggests ferroptosis is a conserved cell death mechanism across animals and plants.
Area of Science:
- Plant biology
- Cell death mechanisms
- Molecular biology
Background:
- Ferroptosis is an iron-dependent, oxidative, non-apoptotic cell death pathway identified in mammalian systems.
- Cell death pathways are crucial for development and stress response in multicellular organisms.
Purpose of the Study:
- To investigate the presence and characteristics of ferroptosis in plants.
- To determine if ferroptosis is conserved between animal and plant kingdoms.
Main Methods:
- Induction of cell death in *Arabidopsis thaliana* using heat shock.
- Microscopic and biochemical analysis to identify hallmarks of ferroptosis.
Main Results:
- A ferroptosis-like cell death process was successfully triggered by heat shock in *Arabidopsis thaliana*.
- The observed plant cell death exhibited key features consistent with mammalian ferroptosis.
Conclusions:
- Ferroptosis is not exclusive to animal cells and can be induced in plants.
- This finding indicates that ferroptosis represents a conserved cell death mechanism conserved across diverse eukaryotic kingdoms, including plants and animals.

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...

01:30Overview of Cell Death
10.6K
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...

4.8K
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.

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...

01:25Cell Signaling in Plants
6.8K
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...

Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.
