Biodiversity of Mineral Nutrient and Trace Element Accumulation in Arabidopsis thaliana

摘要: In order to grow on soils that vary widely in chemical composition, plants have evolved mechanisms for regulating the elemental composition of their tissues balance mineral nutrient and trace element bioavailability soil with requirements plant growth development. The biodiversity exists within a species can be utilized investigate how regulatory individual elements interact identify genes important these processes. We analyzed (ionome) set 96 wild accessions genetic model Arabidopsis thaliana grown hydroponic culture using inductively coupled plasma mass spectrometry (ICP-MS). concentrations 17–19 were roots leaves from hydroponically, seeds artificial soil. Significant effects detected almost every analyzed. observed very few correlations between either or seeds. There many pairs significantly correlated each other tissue, but none consistently across conditions, phenomenon several previous studies. These results suggest ionome tissue is variable, yet tightly controlled by gene×environment interactions. dataset provides valuable resource mapping studies accumulation.
