Maternal Environmental Effects on salt tolerance in Medicago truncatula.

Through allocation of resources to pods and seeds, maternal plants have the capacity to affect the ability of their offspring to tolerate abiotic stress. If abiotic stress is predictable, perhaps due maternal experience of stress and the likelihood of offspring encountering similar conditions, maternal plants can allocate preferentially to offspring to increase stress tolerance. We tested for maternal environmental effects on stress tolerance in Medicagotruncatula by growing 40 genotypes under high and low salinity conditions to generate contrasting maternal environments. Seed germination rate was tested at seven salinity levels, and plants were grown to maturity at two salinity levels. Results show that maternal environmental effects are substantial, particularly at early life stages, and that effects are genotype specific.
