What is the effect of UV-B radiation on phytotechnologies?

Our site has high solar irradiance. While we study plant uptake of metals, we can't ignore that UV-B is a major environmental variable. I need to move beyond "UV causes stress" to specific, measurable endpoints like changes in phenolic compounds, antioxidant activity, or root exudate profiles that could directly interact with our remediation mechanism. What are the key biomarkers?

In my field trials, UV-B's effect is rarely on gross biomass alone; it's a biochemical moderator. I would recommend you prioritize measuring three interconnected responses. First, quantify leaf phenolic compounds, especially flavonoids they act as a sunscreen and their increase is a direct acclimation signal. Second, monitor antioxidant enzyme activity (e.g., catalase, peroxidase) in leaves; a spike indicates oxidative stress management. Crucially, analyze root exudate composition. I have seen UV-B alter exudate profiles, which can shift rhizosphere microbial communities and directly impact metal solubilization and uptake, the core of your remediation process. These are the functional links.
