Summary
Programmed cell death (PCD) is crucial for seed evolution in flowering plants, influencing seed coat and embryo development. This review explores PCD
Area of Science:
- Plant biology
- Reproductive botany
- Developmental biology
Background:
- Angiosperm seed evolution involves significant structural and physiological changes.
- Programmed cell death (PCD) is a key, yet understudied, process in seed development.
- Changes particularly affect the nucellus and endosperm during seed formation.
Purpose of the Study:
- To review the role and examples of PCD during seed development.
- To examine PCD in various seed components like integuments, nucellus, suspensor, and endosperm.
- To consolidate current knowledge on PCD in representative seed examples.
Main Methods:
- Literature review of studies on seed development and PCD.
- Analysis of documented instances of PCD in angiosperm seeds.
- Comparative examination across different seed types.
Main Results:
- PCD occurs in integuments, nucellus, suspensor, and endosperm during seed development.
- Specific examples of PCD are identified in various studied seed types.
- The review highlights the fundamental role of PCD throughout seed evolution.
Conclusions:
- PCD is a significant biological process integral to angiosperm seed evolution.
- Further research is needed to fully elucidate the mechanisms and extent of PCD in seed development.
- Understanding PCD provides insights into plant reproductive strategies.

01:30Overview of Cell Death
11.3K
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
17.1K
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...

02:33Seed Structure and Early Development of the Sporophyte
31.9K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

01:24Caspases
14.6K
Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...

01:25Cell Signaling in Plants
7.1K
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...
