Extended Data Fig. 5: Comparing the Ko and Kc of mutant tobacco and hybrid Arabidopsis Rubisco.

(a) Linear response in Km for CO2 (Kc) with elevating [O2] for the differing Rubiscos. Data shows a collation of measures made on n = 3 to 5 samples (each symbol indicating an independent biological sample). For comparison, the grey dashed line represents the linear fit to the Kc vs [O2] response for wild-type tobacco Rubisco from the top left panel. The mean ( ± SD) values of (b) Kc derived the y-axis (that is where [O2] = 0) and (c) Ko calculated as Kc/slope of the linear fit for each biological sample assayed (circles representing values for each sample). Shown are the mean ( ± SD) of individual values (white circles) from n = 4–6 biological replica measurements as indicated. Lower case letters indicate significant differences to p < 0.05 using a Tukey multiple comparison test with p-values and all data points provided in Source Data Figs. 4 and 5 and Extended Data Fig. 5.
