ARABIDOPSIS HOMOLOG OF TRITHORAX1 impacts lateral root development by epigenetic regulation of targets involved in root system architecture

New Phytologist, Volume 247, Issue 5, Page 2180-2195, September 2025.
Summary Developmental processes are regulated at multiple levels, including the epigenetic level. Among the epigenetic factors, histone H3 lysine 4 (H3K4) methyltransferases contribute to active transcription of target genes, and here, we explored how the H3K4 methyltransferase ARABIDOPSIS HOMOLOG OF TRITHORAX1 (ATX1) affects Arabidopsis thaliana ...
