A. auteur aut IRD text journalArticle eng text/pdf born digital access Plants' ability to respond to environmental stimuli and developmental cues depends upon changes in gene expression. In eukaryotes, genetic information encoded by DNA is packed in a highly regulated and dynamic nucleoprotein complex known as chromatin that is subject to epigenetic modifications. Historically, several biological phenomena relying on epigenetic mechanisms were first characterized in plants. Seminal discoveries such as paramutation and silencing of transposable elements were made in maize (Zea mays). Later rice (Oryza sativa) was selected as a good model for monocotyledons owing to its relatively small genome size and well-annotated sequenced genome. In the past few years an increasing number of epigenetic and epigenomic studies were performed in both maize and rice. In this chapter we will first compare the basic knowledge acquired on epigenetic regulation in rice and maize versus Arabidopsis, then we will describe cereals-specific aspects of epigenetic regulations. specialized DNA METHYLATION PATTERNS TRANSPOSABLE ELEMENTS SMALL RNAS ALLELIC VARIATION IMPRINTED GENES B1 LOCUS MAIZE RICE PARAMUTATION PLANT 076 020 88 361-386 2018 0065-2296 https://www.documentation.ird.fr/hor/PAR00018780 0065-2296 [F A010075425] https://www.documentation.ird.fr/hor/PAR00018780 https://www.documentation.ird.fr/intranet/publi/2019/01/010074864.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-02-04 2019-04-09 PAR00018780 fre
