Aluminum is one of the main factors limiting crop growth in acidic soils, thus, revealing the mechanism involved in soybean aluminum resistance is an important measure in order to improve soybean yield in acidic soils. In this paper, we analyzed transcriptome data from different genotypes of soybean under aluminum stress and found that multiple genes may mediate differences in aluminum tolerance of different soybean genotypes. Through comparative analysis, we found that aluminum-tolerant soybeans had a higher organic acid metabolism compared to sensitive soybeans, while aluminum-tolerant soybeans suffered higher levels of oxidative stress compared to sensitive soybeans. The differences in root elongation of various genotypes of soybeans under aluminum stress is likely to be closely related to the changes in cell wall structural components, among which differential expression of genes encoding POD, PAL, PME, PGIP1, HRGPs and expansin and other enzyme genes plays a key role. These results provide a clear basis for further studies on the relationship between the cell wall and aluminum tolerance of soybeans and their regulation
