Animals and plants can epigenetically silence a widespread genomic parasite, transposable element (TEs), to counteract TEs' selfish increase. However, studies on the genetic basis of a wide array of phenotypic traits suggested that the supposedly beneficial epigenetic silencing of TEs could inadvertently influence nearby host genes' functions. In these examples, the presence of a TE insertion, irrespective of TE type (IAP, MuLE, LINE, or GynohAT), is associated with nearby genes' silencing, contributing to variation in mouse coat color, color streaks in morning glory, bonsai-like Arabidopsis, and female flower of muskmelon.
