Species were assigned to different phylogenetic groups. One phylogenetic group, Spermatophyta, was further divided into C₃ and C₄ species, and C₃ species were further divided into warm- and cool-temperature species according to their optimum growth temperature (T_growth). The two C₃–C₄ intermediate species Flaveria angustifolia and F. floridana were assigned to the group of C₃ plants from warm habitats because they present C₃-like Rubisco kinetics (Perdomo et al., 2015). The optimum growth temperature (T_growth) for each species was either obtained from literature or assigned according to their climate of origin. For Spinacea oleracea, Triticum aestivum and F. pringlei, individual reports’ values and average values for S_c/o of different reports are given. c, scaling constant; ∆H_a, activation energy; K_c, Michaelis–Menten constant for CO₂; K_o, Michaelis–Menten constant for O₂; r, correlation coefficient for linear regressions between measured vs. predicted (Microsoft Excel Solver function) values of each kinetic parameter at the assayed temperatures; Q₁₀, coefficient over the temperature intervals of 5–15 ºC ($Q_{10}^{{}^{15-5}}$), 15–25 ºC ($Q_{10}^{{}^{25-15}}$), 25–35 ºC ($Q_{10}^{{}^{35-25}}$) and 35–45 ºC ($Q_{10}^{{}^{45-35}}$); S_c/o, Rubisco specificity factor for CO₂/O₂; T_meas, range of measurement temperature.

n.d.: r was not determined because measurements consisted in only two assay temperatures.

^a Data from Jordan and Ogren (1984) for Rhodospirillum rubrum consisted of only two measurement temperatures (2 and 25 ºC) and, therefore, $Q_{10}^{{}^{35-25}}$ and $Q_{10}^{{}^{45-35}}$ were not calculated.

^b Due to poor convergence in the Excel Solver (low degree of explained variance), c and ∆H_a for this report were not considered in determining the group averages, and Q₁₀ values were obtained from second-order polynomial fits. Due to high scatter at higher temperature, values of $Q_{10}^{{}^{35-25}}$ and $Q_{10}^{{}^{45-35}}$ from polynomial fits were also unreliable and were therefore not considered for group averages.

^c Data from Hermida-Carrera (2016) consisted of measurements at three temperatures (15, 25 and 35 ºC), and the assays were performed following the procedures described in Galmés et al. (2014b).

^d Low adjustment of the Excel Solver; c and ∆H_a for this report were not considered in calculating the averages for Spinacea oleracea.

^e Young et al. (2015) consists of only two measurement temperatures (0 and 20 ºC); $Q_{10}^{{}^{35-25}}$ and $Q_{10}^{{}^{45-35}}$ were not calculated.

^f Low adjustment of the Excel Solver; c and ∆H_a of this report were not considered for group averages.

^g r is not provided given the large scattering between measured vs. predicted values.
