Concentration-dependent transcriptional switching through a collective action of cis-elements (Sci. Adv.)
One of the well-known molecular pathways that regulate plant development is the one formed by the homeobox transcription factor WUSCHEL (WUS) and the secreted peptide CLAVATA 3 (CLV3). In the shoot apical meristem (SAM), WUS expression is constrained to the organizing center where it maintains the stem…
