Summary
Slime mould Physarum polycephalum exhibits biased rightward turning in laboratory experiments. This study reveals consistent laterality in the fungi kingdom, adding to known asymmetric behaviors in other organisms.
Area of Science:
- Developmental Biology
- Cell Biology
- Mycology
Background:
- Left-right patterning and lateralized behavior are common in plants and animals.
- The link between cellular chirality and large-scale asymmetry in multicellular organisms is not fully understood.
- Cellular chirality is hypothesized to be determined by the cytoskeleton.
Purpose of the Study:
- To investigate biased asymmetry in the slime mould Physarum polycephalum.
- To determine if this unicellular organism exhibits consistent laterality.
- To explore the presence of laterality in the fungi kingdom.
Main Methods:
- Laboratory experiments using a T-shaped maze.
- Observation and quantification of turning behavior in Physarum polycephalum.
- Statistical analysis of directional preference.
Main Results:
- Physarum polycephalum demonstrated a significant rightward turning bias, occurring in over 74% of trials.
- This finding represents the first documented instance of consistent laterality in fungi.
- The results align with previously observed asymmetric movement in various cell types.
Conclusions:
- Physarum polycephalum exhibits a consistent, biased laterality.
- This study expands the understanding of asymmetric behavior to the fungal kingdom.
- The precise mechanisms underlying the slime mould's directional preference require further investigation.

Chirality
32.2K
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Chirality in Nature
17.9K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Molecules with Multiple Chiral Centers
16.4K
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2,3-diol have multiple chiral centers. A simple formula to predict the number of stereoisomers possible for a molecule with n chiral centers is 2n. However, there can be a lower number where some of the stereoisomers are...

Chirality at Nitrogen, Phosphorus, and Sulfur
7.4K
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.
A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...

Prochirality
5.3K
The concept of prochirality leads to the nomenclature of the individual faces of a molecule and plays a crucial role in the enantioselective reaction. It is a concept where two or more achiral molecules react to produce chiral products. A typical process is the reaction of an achiral ketone to generate a chiral alcohol. Here, the achiral reactant reacts with an achiral reducing agent, sodium borohydride, to generate an equimolar mixture of the chiral enantiomers of the product. For example, an...

Diversity of Protists IV
2.1K
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
