Submergence-responsive MicroRNAs are Potentially Involved in the Regulation of Morphological and Metabolic Adaptations in Maize Root Cells

摘要

Background and AimsAnaerobic or low oxygen conditions occur when maize plants are submerged or subjected to flooding of the soil. Maize survival under low oxygen conditions is largely dependent on metabolic, physiological and morphological adaptation strategies; the regulation mechanisms of which remain unknown. MicroRNAs (miRNAs) play critical roles in the response to adverse biotic or abiotic stresses at the post-transcriptional level. The aim of this study was to understand submergence-responsive miRNAs and their potential roles in submerged maize roots.
