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 highly hypoxic under normal oxygen tension. When hypoxia is imposed to the […]
