Ubiquitination of BAM1 attenuates CLE peptide–mediated signaling in the root apical meristem

Proceedings of the National Academy of Sciences, Volume 123, Issue 4, January 2026. <br/>SignificanceThe receptor kinase BARELY ANY MERISTEM1 (BAM1) drives phloem formation and regulates other aspects of root development. However, the mechanisms underlying BAM1 degradation remain unclear. Our study reveals that two closely related ubiquitin …
