Challenging environments have forced plants to develop exceptional phenotypic variation resulting from genetic variation and its interaction with the environment. However, complex heritable traits are not only determined by changes in the DNA sequence.
Epigenetic modifications triggered by environmental factors contribute to the phenotypic variation within a generation and allow information to be transferred to the next generation without genetic mutations.
Although it is a well-known phenomenon that defense responses induced in the parental generation can increase resistance of the offspring, virtually nothing is known about the underlying molecular mechanisms. We investigate whether differential DNA methylation patterns impact the glucosinolate defense compounds and aim at identifying novel genes involved in epigenetic inheritance of plant resistance.
