Summary
Sensory texture significantly impacts citrus organoleptic quality, driven by cell wall components. This study used mRNA sequencing to identify genes regulating citrus texture, providing insights into fruit quality mechanisms.
Area of Science:
- Plant Biology
- Molecular Biology
- Food Science
Background:
- Sensory texture is a key factor in the organoleptic qualities of fresh fruit.
- Plant cell wall components like pectin, cellulose, hemicellulose, and lignin are crucial for determining textural properties.
Purpose of the Study:
- To explore genes and regulatory pathways influencing the perceived sensory texture of fresh citrus.
- To compare transcriptomic profiles of citrus segment membranes from two cultivars with distinct textures.
Main Methods:
- mRNA sequencing (mRNA-seq) was performed on segment membranes of Shiranui and Kiyomi citrus cultivars at two developmental stages.
- Differential gene expression analysis and gene ontology enrichment were conducted.
- Chemical component analysis of mature fruit segment membranes was performed.
Main Results:
- Over 3000 differentially expressed genes were identified between the two cultivars.
- Enriched pathways were predominantly related to metabolism, with more categories significant in 'Shiranui'.
- Key genes involved in pectin, cellulose, hemicellulose, and lignin synthesis were identified, and chemical analysis showed higher pectin, cellulose, and lignin content in 'Kiyomi' segment membranes.
Conclusions:
- Citrus organoleptic quality is significantly influenced by sensory texture, primarily determined by segment membrane properties.
- Transcriptomic analysis revealed distinct gene expression profiles related to cell wall metabolism in citrus cultivars with different textures.
- This study offers insights into the genetic mechanisms underlying citrus sensory texture and fruit quality.

02:43Plant 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.Collenchyma and sclerenchyma cells, on the other hand, mainly occur in the outer layers of a plant's stems and leaves. These cells provide the plant with strength and support by either partially thickening their primary cell wall (i.e., collenchyma), or depositing a...
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.
01:07Plant Cell Wall
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...
