Differential Methylation during Maize Leaf Growth Targets Developmentally Regulated Genes      

Abstract: DNA methylation is an important and widespread epigenetic modification in plant genomes, mediated by DNA methyltransferases (DMTs). DNA methylation is known to play a role in genome protection, regulation of gene expression, and splicing and was previously associated with major developmental reprogramming in plants, such as vernalization and transition to flowering. Here, we show that DNA methylation also controls the growth processes of cell division and cell expansion within a growing organ. The maize (Zea m… Show more

“…Much overlap was found between the GRFs identified in leaf and ear, indicating that some GRFs might be universally associated with growth processes such as division and expansion. Our experiments clarify which of the many GRFs that all show zone-specific expression profiles (Candaele et al, 2014; Supplemental Figure 3) are predominantly associated with AN3/GIF1, information that could not be deduced from the transcriptome data alone. The dynamics of the transcript levels of the identified GRFs within the maize leaf growth zone (all GRF genes except GRF4 and GRF10 were more highly expressed at the division zone compared with the expansion zone) matched their dynamics in protein accumulation within the complex.…”

“…While bait, tag, and copurified core subunits did not change between the division and expansion zone, 12 proteins were significantly enriched in the dividing tissue ( Figure 2; Supplemental Table 4). Among these proteins, we found GRF1, GRF6, GRF7, GRF12, GRF15, and GRF17, GRFs that all contain an miR396a target site (Candaele et al, 2014), while the miR396a-resistant GRFs, GRF4 and GRF10, did not show changes in their abundance between the two zones ( Figure 2). The expression level of the GRF genes was evaluated along the leaf gradient using quantitative RT-PCR.…”
