Scientists Miriam Paredes and Maria Quiles led an investigation on the plant species Rosa Meillandina, and its metabolic response to water deficit.  They noted how limited water irrigation can cause a reduction in PS II levels, which then results in the inhibition of photosynthesis. Paredes and Quiles also noticed the increase in chlororespiration activity as a protective mechanism for the lack of photosynthesis.
In the experiment, the plants in water deficit were analysed with fluorescence imaging technique. This form of analysis detected increased levels of PTOX, and NAD(P)H activity within the plant.  An increase in these two molecules led to the initiation of chlororespiration.
N-propyl gallate was also added to these water deficit plants. The effect resulted in increased chlorophyll fluorescence levels.  Quiles recorded a similar outcome in the same species of plants that went under intense light.  This increase in chlorophyll fluorescence is attributed to the influx of NAD(P)H in the thylakoid membrane.  Which then led to an increase in the by-product, hydrogen peroxide, inside the thylakoid membrane.
