Summary
This review explores the five basic tastes, examining the molecular and cellular basis of taste perception. It reveals that distinct taste cells activate specific taste qualities, varying across species.
Area of Science:
- Neuroscience
- Sensory Biology
- Molecular Biology
Background:
- Taste perception involves specialized cells in oral epithelia.
- The five basic tastes (sweet, umami, bitter, sour, salty) lack clear evolutionary justification.
- Understanding the diversity of taste cells is key to understanding taste quality.
Purpose of the Study:
- To dissect the peripheral gustatory system in vertebrates.
- To explain the molecular and cellular mechanisms underlying the five basic tastes.
- To explore the evolutionary reasons for the specific set of basic tastes.
Main Methods:
- Review of recent behavioral studies.
- Analysis of molecular genetic studies.
- Examination of functional taste receptors and cells.
Main Results:
- Different taste qualities are mediated by distinct subsets of taste receptor cells.
- The diversity of taste buds and their cellular composition varies significantly among species.
- Functional taste receptors and cells have been identified through genetic and behavioral studies.
Conclusions:
- The diversity of basic tastes is intrinsically linked to the diversity of taste cells within taste buds.
- Species-specific variations in taste cell populations may explain differences in taste perception.
- Further research into taste cell diversity can elucidate the evolutionary pathways of taste perception.

Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
The Tongue and Taste Buds
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
The Physiology of Taste
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the diffusion of...
Gustation
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
Introduction to Special Senses
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive functions.
Gene Duplication and Divergence
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.
