# Salt chemotaxis and its plasticity in hermaphroditic nematodes

## TL;DR

This study explores salt chemotaxis in several nematode species, finding that most show similar abilities to C. elegans, suggesting they could be useful for future research.

## Contribution

The study identifies multiple nematode species with salt chemotaxis plasticity, expanding potential model organisms for chemosensation research.

## Key findings

- Most nematode species tested showed salt chemotaxis plasticity similar to C. elegans.
- The results highlight the biological importance of salt chemotaxis across species.
- These species could serve as alternative models for future chemosensation studies.

## Abstract

Salt chemotaxis in the nematode

Caenorhabditis elegans

has been used as a model to study chemosensation, behavior, and learning and memory. To investigate whether other nematode species could serve as alternative models, we examined salt chemotaxis plasticity in five androdioecious nematode species—

Caenorhabditis briggsae

,

Caenorhabditis tropicalis

,
Oscheius myriophilus
,

Oscheius tipulae

, and

Pristionchus pacificus

—all isolated as wild type. Most strains exhibited salt chemotaxis plasticity similar to that of

C. elegans

, underscoring the biological importance of this ability and supporting their potential use in future research on salt chemotaxis.
