Summary
Fruit expansion in Fragaria vesca involves simultaneous cell separation and cell wall disassembly. These processes are critical for coordinated fruit growth and ripening.
Area of Science:
- Plant Biology
- Fruit Development
- Cell Biology
Background:
- Fruit expansion during ripening is a complex process.
- The underlying structural and metabolic mechanisms are not fully understood.
Purpose of the Study:
- To investigate the roles of cell separation and cell wall metabolism in Fragaria vesca fruit expansion.
- To elucidate the coordinated regulation of fruit growth and ripening.
Main Methods:
- Anatomical observations of fruit development.
- Histochemical analysis.
- Cell wall composition analysis.
Main Results:
- Cell separation occurs early in fruit development, increasing apoplastic space.
- Massive cellulose disassembly correlates with cell and fruit volume expansion.
- Cell separation is linked to cell wall metabolism.
Conclusions:
- Cell separation, cell elongation, and cell wall disassembly are simultaneous events during Fragaria vesca ripening.
- These processes are critical for coordinated fruit expansion.

01:58Fruit Development, Structure, and Function
24.5K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

4.4K
Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth. Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.

01:59The Phragmoplast
6.0K
Cell division is essential for organismal growth and development. In animal cells, the central spindle and its associated proteins form the midbody, a structure that has an essential role in cytokinesis. In plants, the central spindle, along with the microtubules, actin, and other cell components, matures into the phragmoplast, which is necessary for cytokinesis. Unlike the stationary midbody, the phragmoplast expands centrifugally, eventually leading to the formation of the new cell wall.

The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

01:07Plant Cell Wall
6.9K
Plant cells have a cell wall, a rigid outer covering that protects the cell and provides shape and support. During cell division, a mixture of enzymes, proteins, and glucose molecules is transported via vesicles to the center of the cell. These vesicles continuously fuse and build a cell plate between the dividing cells. As the cell plate matures, new polysaccharides are added to it to form the cell walls of the daughter cells. The predominant polysaccharide in the cell wall is cellulose, made...

01:02Role of Microtubules in Cell Wall Deposition
2.8K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...
