Summary
Vibration damages kiwifruit texture by breaking down pectin. Applying 1-methylcyclopropene (1-MCP) preserves pectin structure, reducing texture loss during transport.
Area of Science:
- Food Science
- Plant Physiology
- Biochemistry
Background:
- Transportation vibration accelerates fruit texture deterioration.
- Understanding the molecular mechanisms of vibration-induced texture loss is crucial for improving postharvest quality.
Purpose of the Study:
- To elucidate the molecular basis of vibration-induced texture deterioration in kiwifruit.
- To evaluate 1-methylcyclopropene (1-MCP) as a potential intervention to mitigate texture loss.
Main Methods:
- Analysis of pectin composition and nanostructure.
- Transcriptomic analysis of pectin-modifying genes.
- Molecular docking simulations.
Main Results:
- Vibration stress led to pectin solubilization and nanostructural changes.
- 1-MCP treatment maintained pectin integrity, increasing chelate-soluble and sodium-carbonate-soluble pectin.
- Vibration upregulated pectin-degrading genes (PG, β-galactosidase, PME), while 1-MCP downregulated them.
- Molecular docking provided insights into pectin de-esterification and depolymerization.
Conclusions:
- Vibration stress causes kiwifruit texture deterioration through pectin modification.
- 1-MCP is an effective strategy to preserve pectin structure and delay texture loss under vibration stress.

01:28Biodeterioration
Biodeterioration refers to the unwanted alteration of materials caused by microorganisms—especially fungi—which damage both organic substrates (paper, wood, textiles) and inorganic ones (stone, plaster, glass). Unlike abiotic decay, biodeterioration results from biological activity that produces physical disruption and chemical degradation.Physical deterioration occurs as fungal hyphae penetrate pores, cracks, and surface irregularities. Hyphal turgor pressure, thigmotropic growth along...
01:58Fruit Development, Structure, and Function
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.
01:15Cellulose and Pectic Polysaccharides
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.
As a cell matures, its cell wall specializes according to its type. For example, the parenchyma cells of...

01:02Role of Microtubules in Cell Wall Deposition
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 disassembly and...
