How do DRN & WUS upregulate CLV3 transcription in #plant shoot #ApicalMeristem? This study shows that DRN interferes with WUS dimerization & #ChromatinRemodeling to activate CLV3 transcription, so helping to maintain the shoot stem cell pool #PLOSBiology https://plos.io/3AyF1je
DRN facilitates WUS transcriptional regulatory activity by chromatin remodeling to regulate shoot stem cell homeostasis in Arabidopsis

DRN and WUS are known to upregulate the transcription of CLV3 in the shoot apical meristem of Arabidopsis, but how remains unclear. In this study, DRN is shown to interfere with WUS dimerization and chromatin remodeling to activate CLV3 transcription, thus contributing to the maintenance of the shoot stem cell pool.
