Figure 5 in Hydrogen peroxide is involved in drought stress long-distance signaling controlling early stomatal closure in tomato plants
Figure 5. Growth analysis of shoots and roots of tomato BS II0020 grown under irrigated or drought conditions. (A) fresh weight; (b) dry weight; (c) foliar area; (d) height. Control plants received full irrigation throughout the experiment. The values are the means of each treatment (n= 4), followed by the standard error. The letters over the bars represent the differences in the means between biochemical treatments within each condition, and the asterisks the differences of the same biochemical treatment between the conditions, calculated by Scott-knott test at 5% probability.

Figure 7 in Hydrogen peroxide is involved in drought stress long-distance signaling controlling early stomatal closure in tomato plants
Figure 7. Schematic representation of the proposed model for the role of H 2O2 in drought stress responses in tomato plants before and after the decline in shoot turgor. Thus, when there is a mild drought stress, the H O produced by the roots can travel to the shoot 2 2 where it will induce stomatal closure and thus reduce water loss, even before there is a reduction in the leaves water status. On the other hand, when drought stress becomes severe, other signals become part of the drought response complex, such as hormones, pH changes and electrical current, among others. Currently, H O appears to exert a lesser effect on drought signaling. *Several signals, such 2 2 as hormones, chemical elements, reactive nitrogen species, electrical currents, hydraulic signals and pH changes (Christmann et al., 2013; Silva et al., 2015; Karuppanapandian et al., 2017; Huber et al., 2019; Fichman and Mittler, 2020; Mahmood et al., 2020).
Figure 3 in Hydrogen peroxide is involved in drought stress long-distance signaling controlling early stomatal closure in tomato plants
Figure 3. Water relations of tomato BS II0020 grown in split-root scheme under full or partial irrigation. (a) relative water content; (b) total transpiration of plants throughout the evaluation period; (c) transpiration per cm2 of leaf area; (d) water use efficiency. Control plants received full irrigation throughout the experiment. The values are the means of each treatment (n= 4), followed by the standard error. The letters over the bars represent the differences in the means among biochemical treatments within each condition, and the asterisks the differences of the same biochemical treatment between the conditions, calculated by Scott-knott test at 5% probability.

Unraveling the interaction between singlet state atomic oxygen and water: toward the formation of oxywater and hydrogen peroxide
<p>We provide example input files to perform simulations of our article "Unraveling the interaction between singlet state atomic oxygen O(1D) and water: toward the formation of oxywater and hydrogen peroxide". In addition, we provide the output files together with a python script to caclulate the reaction rate of oxywater transition to hydrogenperoxide.
