摘 要：Oxygen is essential for plant growth and *** occurs in plants due to limited oxygen avail-abilityfollowing adverse environmental conditions as well inhypoxic niches in otherwisenormoxic ***,the existence and functional integration of spatiotemporal oxygen dynamics with plant development remains *** animal systems dynamic fluctuations in oxygen availability are known as cyclic *** this study,we demonstrate that cyclic fluctuations in internal oxygen levels occur in young emerging leaves of Arabidopsis *** hypoxia in plants is based on a mechanism requiring the ETHYLENE RESPONSE FACTORS type VII(ERFVII)that are central components of the oxygen-sensing machinery in *** ERFVll-dependent mechanism allows precise adjustment of leaf growth in response to carbon status and oxygen availability within plant *** study thus establishes a functional connection between internal spatiotemporal oxygen dynamics and developmental processes of plants.
