Abstract
Hypoxia (low-oxygen tension) caused by complete submergence or waterlogging is an abiotic stress factor that severely affects the yield and distribution of plants. To adapt to and survive under hypoxic conditions, plants employ several physiological and molecular strategies that integrate morphological acclimation, metabolic shifts, and signaling networks. Group VII ETHYLENE RESPONSE FACTORS (ERF-VIIs), master transcription factors, have emerged as a molecular hub for regulating plant hypoxia sensing and signaling. Several mitogen-activated protein kinases and calcium-dependent protein kinases have recently been reported to be involved in potentiating hypoxia signaling via interaction with and phosphorylation of ERF-VIIs. Here, we provide an overview of the current knowledge on the regulatory network of ERF-VIIs and their post-translational regulation in determining plant responses to hypoxia and reoxygenation, with a primary focus on recent advancements in understanding how signaling molecules, including ethylene, long-chain acyl-CoA, phosphatidic acid, and nitric oxide, are involved in the regulation of ERV-VII activities. Furthermore, we propose future directions for investigating the intricate crosstalk between plant growth and hypoxic resilience, which is central to guiding breeding and agricultural management strategies for promoting flooding and submergence stress tolerance in plants.
