Drought stress has transgenerational effects on seeds and seedlings in winter oilseed rape (Brassica napus L.).

ABSTRACT:

Background

Drought stress has a negative effect on both seed yield and seed quality in Brassica napus (oilseed rape, canola). Here we show that while drought impairs the maternal plant performance, it also increases the vigour of progeny of stressed maternal plants. We investigated the transgenerational influence of abiotic stress by detailed analysis of yield, seed quality, and seedling performance on a growth-related and metabolic level. Seeds of eight diverse winter oilseed rape genotypes were generated under well-watered and drought stress conditions under controlled-environment conditions in large plant containers.

Results

We found a decrease in seed quality in seeds derived from mother plants that were exposed to drought stress. At the same time, the seeds that develop
