Since its publication, the author of Lüttge (2006) has brought to our attention that an error appears in the legend to Fig. 2 where the phases of CAM are labeled incorrectly.


Figure 2. CO2 gas exchange curves (inline image) of Clusia minor L. under three different conditions (A–C) and Clusia venosa Jacq. (D), Clusia alata Pl. et Tr. (E) and Clusia major L. (F), showing performance of C3 photosynthesis (A, D), crassulacean acid metabolism (CAM) (B, E, F), with the four phases of (I) nocturnal CO2 uptake, (III) daytime stomatal closure and organic acid remobilization, (II) a transition with CO2 uptake in the early light period, and (IV) CO2 uptake in the later light period (Osmond, 1978), and CO2 uptake almost around the clock and strong expression of all four CAM phases (C). In (A–C) for C. minor, the irradiance and water vapour pressure deficit (VPD) of the atmosphere in µmol m−2 s−1/mbar bar−1, respectively, were as follows: (A) 1700/6.6, (B) 400/13.5, (C) 400/3.5, i.e. high irradiance and low VPD favoured C3 photosynthesis, medium irradiance and high VPD favoured CAM, and medium irradiance and very low VPD favoured CO2 uptake around the clock. Dark bars, night-time; white bars, daytime. (After data of Lee et al., 1989, where C. minor is wrongly named C. rosea, and Franco et al., 1990.)
