Outline of Final Research Achievements |
In the acid soil of world arable land, mainly Aluminum and proton inhibit the crop growth of crop. In the present study, we conducted genome-wide association study (GWAS) for Al- and proton stress tolerance using approximately 200,000 SNPs among 200 Arabidopsis accessions. In the results, we detected over 100 gene regions which explain approximately 70% of variation in both Al- and proton-tolerance, and then we identified novel genes associated with the Al tolerance. In addition, we revealed that some polymorphisms in the promoter region of AtALMT1 gene are involved in the Al tolerance.
