MiRNA Sequencing Analysis in Maize Roots Treated with Neutral and Alkaline Salts.

ABSTRACT: Soil salinization/alkalization is a complex environmental factor that includes not only neutral salt NaCl but also other components like Na₂CO₃. miRNAs, as small molecules that regulate gene expression post-transcriptionally, are involved in plant responses to abiotic stress. In this study, maize seedling roots were treated for 5 h with 100 mM NaCl, 50 mM Na₂CO₃, and H₂O, respectively. Sequencing analysis of differentially expressed miRNAs under these conditions revealed that the Na₂CO₃ treatment group had the most differentially expressed miRNAs. Cluster analysis indicated their main involvement in the regulation of ion transport, binding, metabolism, and phenylpropanoid and flavonoid biosynthesis pathways. The u
