DECREASE IN DNA METHYLATION 1-mediated epigenetic regulation maintains gene expression balance required for heterosis in Arabidopsis thaliana

Kodai Matsuo, Rui Wu, Hiroto Yonechi, Terumi Murakami, Satoshi Takahashi, Asuka Kamio, Mst. Arjina Akter, Yoshiki Kamiya, Keita Nishimura, Takakazu Matsuura, Kaoru Tonosaki, Motoki Shimizu, Yoko Ikeda, Hisato Kobayashi, Motoaki Seki, , Ryo Fujimoto

This study shows that loss of DDM1 reduces biomass heterosis in Arabidopsis hybrids by disrupting DNA methylation and transcriptome stability, revealing a salicylic acid-independent epigenetic mechanism.
