Abstract

• Long-term exposure to high light (HL) increases reactive oxygen species (ROS) production causing damages to DNA, proteins, and lipids, as well as to components of the photosynthetic apparatus. Plants have evolved different mechanisms to enhance the dissipation of the excess light energy under HL. The Systemic Acquired Acclimation (SAA) has been demonstrated to be an effective mean in Arabidopsis against oxidative damage. In this species, a systemic signal is rapidly transmitted from high-lighted exposed to distal shaded leaves, resulting in improved tolerance to oxidative stress. This work aimed to evaluate the possible role of SAA in photoprotection in common bean plants. To test this hypothesis, upper leaves of bean were exposed for 2h to high light (HL), whereas the below leaves were shaded (LL). After, LL leaves were exposed to high light (LL->HL). In HL, LL and LL->HL leaves, gas exchange and chlorophyll a fluorescence measurements were performed to assess the functionality of photosynthetic apparatus, whereas poly(ADP-ribose) polymerase (PARP) expression and activity, total antioxidant capacity and H2O2 content were monitored to evaluate the incidence of oxidative stress. The overall results were pondered to estimate the potential for photoprotection in bean plants due to the possible occurrence of SAA mechanism. (literal)
