GRIPP Plant Chemistry

Using advanced analytical approaches including ultra performance liquid chromatography coupled with mass spectrometry (UPLC-MS), GRIPP members are currently researching how specific chemicals produced in plants mediate growth and development processes such as reproduction, circadian rhythms, senescence, and protection against environmental stresses including cold, UV, and toxic ions. By studying plant-environment interactions over time, GRIPP researchers can develop new processes for conserving, propagating and re-distributing plant species which are generally hard to grow by mimicking specific growth conditions through the application of plant growth regulating chemicals.
