Insights into aluminum-tolerance pathways in Stylosanthes as revealed by RNA-Seq analysis.

ABSTRACT: Stylo has a great potential for Al³⁺ resistance in acidic soils through secretion of citrate from the roots. To get insight into the molecular mechanisms responsible, transcriptomic changes were investigated in the roots after treatment with T01 (-Al³⁺, pH6.0), T02 (-Al³⁺, pH4.3) and T03 (50 µM AlCl₃, pH4.3). In total, 83,197 unigenes generated from 130,933 contigs were obtained. Of them, 282, 148 and 816 differentially expressed unigenes (DEGs) were revealed in T01_vs_T02, T02_vs_T03 and T01_vs_T03 comparison, respectively (FDR < 0.001, log₂FC > 2). DEGs by Al³⁺ were related to G-proteins, diacyglycerol and inositol metabolism, calcium-signaling, transcription regulation, protein modification and transporters for detoxifica
