As droughts in California become more severe, understanding how native populations will react is crucial to conservation success. When compounded with elevated concentrations of soil-borne nitrogen, water availability in plants may drive plasticity in their root morphologies. In this study, a genome-wide (multi-population) representation of the riparian coastal sage scrub species Baccharis salicifolia (mulefat) will be used to model possible trends in belowground structural architecture. Individuals from throughout the plant s distribution will be sampled, and placed at random into 4 separate treatments consisting of a combination of low and high water and nitrogen. As well as propagating to facilitate cloning and using WinRHIZO software to scan root structures, individuals will also be subjected to a simulated drought, where a zero-water time-to-death scenario will be used to determine plant performance under severe drought conditions.
