|a In the past decade, plant biologists and breeders have developed a growing interest in the field of epigenetics, which is defined as the study of heritable changes in gene expression that cannot be explained by changes in the DNA sequence. Epigenetic marks can be responsive to the environment, and evolve faster than genetic changes. Therefore, epigenetic diversity may represent an unexplored resource of natural variation that could be used in plant breeding programmes. On the other hand, crop genomes are largely populated with transposable elements (TEs) that are efficiently targeted by epigenetic marks, and part of the epigenetic diversity observed might be explained by TE polymorphisms. Characterizing the degree to which TEs influence epigenetic variation in crops is therefore a major goal to better use epigenetic variation. To date, epigenetic analyses have been mainly focused on the model plant Arabidopsis thaliana, and have provided clues on epigenome features, components that silence pathways, and effects of silencing impairment. But to what extent can Arabidopsis be used as a model for the epigenomics of crops? In this review, we discuss the similarities and differences between the epigenomes of Arabidopsis and crops. We explore the relationship between TEs and epigenomes, focusing on TE silencing control and escape, and the impact of TE mobility on epigenomic variation. Finally, we provide insights into challenges to tackle, and future directions to take in the route towards using epigenetic diversity in plant breeding programmes
