The prevalence of soluble aluminum (Al) ions is one the major limitations to crop production worldwide on acid soils. Therefore, understanding Al tolerance mechanism rice and applying functional genes in sensitive plants can significantly improve stress resistance. In this study, transcriptomics metabolomics analyses were performed reveal differences between two landraces (Al-tolerant genotype Shibanzhan (KR) Al-sensitive Hekedanuo (MR) with different tolerance. results showed that DEG related phenylpropanoid biosynthesis was highly enriched KR MR after stress, indicating may be closely E1.11.1.7 (peroxidase) most significant enzyme under regulated by multiple genes. We further identified candidate Os02g0770800 Os06g0521900 involved regulation rice. Our not only resistance some extent, but also provide a useful reference for molecular effects poisoning plants.
