Silicon isotopic fractionation under water stress in Sorghum bicolor: evidence from in situ morphotype-specific phytolith analysis
Our findings align with prior research suggesting that water stress affects Si uptake, potentially altering the Si-water movement relationship. The significant variability in the isotopic data measured indicates the potential involvement of additional environmental, and consequently physiological factors influencing silicon isotope composition in phytoliths, especially Bulliform, which we suggest should be the focus of future research. Our model offers a solid foundation for research in several fields, from agronomic studies aimed at using Si to improve drought-resistance, to palaeoenvironmental and archaeological studies aimed at reconstructing past climate change and human-environment interactions.
