Abstract:

Oxygen is an essential substance for plants, and adequate oxygen supply is necessary for plant growth and developments. As one of the major abiotic threats to plants, frequent floods could lead to oxygen deficiency in the rhizosphere. Therefore, it is important to understand the response and adaptive mechanisms of plants to rhizosphere oxygen concentration for crop productions and breeding of resistant varieties. This review shed light on the impacts of rhizosphere oxygen contents on plants from multiple perspectives. We also demonstrated the injury and acclimations caused by oxygen deficiency and the mechanism of low-oxygen signaling. We finally summarized methods to avoid oxygen deficit and prospect of further studies.

Key words: rhizosphere oxygen content, adaptation mechanism, oxygen signaling, internal oxygen concentration, aeration
