Plants exhibit phenotypic plasticity in response to changes in their environment, such as soil
composition, presence of pathogens or soil engineers like earthworms. Worms are known to
improve plant growth. However, the extent of worm effects depends on plant species, worm and
soil types. To date, plant plasticity in response of earthworms has essentially been assessed
through measurements of biomass production.
In the present work, we propose a new approach to study earthworm effects on plant plasticity in
which plant phenotypic variations are correlated with variations in the expression levels of several
genes involved in cellular division and responses to stress. To do so, an original experimental
setup was designed in which as many parameters as possible were tightly controlled. Individual
Arabidopsis thaliana plants were grown with (or without) Aporrectodea caliginosa earthworms
in two types of soil, a rich one or a poor soil almost free of organic matter and nitrogen.
In the poor soil, plant phenotype was typical of nitrogen-starved plants, with a reduced aerial
biomass production and an over-developed root system. However, earthworms restored
vegetative and reproductive biomass production to the levels observed in the rich soil. In leaves,
this seemed to correspond to increased cell divisions and enhanced defence against reactive
oxygen species. Regardless of soil quality, worms significantly decreased length and biomass
of the root systems, suggesting an improvement of plant mineral uptake. This hypothesis was
confirmed by plant C:N analyses that revealed general N enrichment in all plants. Furthermore,
worms decreased ammonium contents in both soils whereas they strongly increased nitrogen
content in the poor soil.
These experiments clearly showed effects of worms on soil mineral status and on nutrient uptake
in plants leading to better resource allocation MenosPlants exhibit phenotypic plasticity in response to changes in their environment, such as soil
