Plant stem cells under low oxygen: metabolic rewiring by phytoglobin underlies stem cell functionality

When flooding occurs, soils become saturated and oxygen solubility and diffusion decreases. This situation creates a hypoxic environment in the roots that stresses the plant, causing significantly decreased growth. However, the quiescent center (QC) stem cells, located in the root apical meristem, are…

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…
