Transcriptome Analysis Revealed the Potential Molecular Mechanism of Anthocyanidins’ Improved Salt Tolerance in Maize Seedlings

Anthocyanin, a kind of flavonoid, plays crucial role in plant resistance to abiotic stress. Salt stress is that can damage the growth and development seedlings. However, limited research has been conducted on involvement maize seedlings salt via anthocyanin accumulation, its potential molecular mechanism still unclear. Therefore, it great significance for normal explore improving tolerance transcriptome analysis. In this study, we identified two W22 inbred lines (tolerant line pur–W22 sensitive bro–W22) exhibiting differential during seedling but showing no significant differences characteristics under non–treatment conditions. order identify specific genes involved seedlings’ response, generated recombinant (RILpur–W22 RILbro–W22) by crossing bro–W22, then performed analysis grown both treatment A total 6100 5710 differentially expressed (DEGs) were RILpur–W22 RILbro–W22 seedlings, respectively, salt–stressed conditions when compared non–treated groups. Among these DEGs, 3160 as being present RILbro–W22, served commonly stressed EDGs mainly enriched redox process, monomer metabolic catalytic activity, plasma membrane, process regulation. Furthermore, detected 1728 DEGs salt–tolerant not salt–sensitive line, which 887 upregulated 841 downregulated. These are primarily associated with processes, biological regulation, membrane. Notably, synthesis related strongly induced conditions, was consistented phenotype summary, results only expanded our understanding complex also, specifically (RILpur–W22) provided candidate further genetic
