Variegated Canvases: The Diverse World of Plant Shoot Stem Cells
The Plant Cell: In a NutshellBradamante et al. investigate the heterogeneity of stem cells of the shoot apical meristem

Background: In plants, stem cells in the shoot apical meristem (SAM) produce new organs…
Review: Stem cells for crop improvement
Plant Science Research WeeklyPlants, like animals, have small populations of stem cells capable of differentiating into other tissues, but in plants these stem cell populations are even more long-lived and versatile. Stem cells in plants include the meristems (shoot and root apical meristems, inflorescence and axillary meristems)…
Plant stem cells under low oxygen: metabolic rewiring by phytoglobin underlies stem cell functionality
Plant Science Research WeeklyWhen 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.)
Plant Science Research WeeklyOne 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…
