| Outline of Final Research Achievements |
Soil pH has a large impact on availability of mineral elements. For example, at a low pH, Al is solubilized to inhibit plant growth, while at a high pH, Fe availability becomes very low. However, different plant species show different adaptability to soil pH. Among cereal crops, rice is highly tolerant to Al but relatively sensitive to Fe-deficiency. By contrast, barley is the most sensitive to Al but highly tolerant to Fe-deficiency, while rye is able to adapt to a wide range of soil pHs. However, the molecular mechanisms underlying these differences are poorly understood. In this study, we conducted a comparative transcriptome analysis. Rice (WT, art1, star1), barley and rye were exposed to three different solutions (low pH with Al, moderate pH, or high pH with less Fe) for a short period, the roots were subjected to RNA-seq. The difference in gene expression in response to different pH were compared.
