phenotype expression in land plants, although discerning the epigenetic contribution is
difficult. Agriculturally important attributes like heterosis, inbreeding depression, phenotypic
plasticity, and environmental stress response are thought to have significant epigenetic
components, but unequivocal demonstration of this is often infeasible. Here, we investigate
gene silencing of a single nuclear gene, MutS HOMOLOG1 (MSH1), in the tomato (Solanum …
