The DOMAINS REARRANGED METHYLTRANSFERASEs (DRMs) are crucial for RNA‐directed DNA methylation (RdDM) in plant species. Setaria viridis is a model monocot species with a relatively compact genome that has limited transposable element (TE) content. CRISPR‐based genome editing approaches were used to create loss‐of‐function alleles for the two putative functional DRM genes in S. viridis to probe the...
The plant hormone auxin plays a critical role in root growth and development; however, the contributions or specific roles of cell‐type auxin signals in root growth and development are not well understood. Here, we mapped tissue and cell types that are important for auxin‐mediated root growth and development by manipulating the local response and synthesis of auxin. Repressing auxin signaling in the...
