“…The key message is that similar responses have been observed in wheat (Zhang et al, 2008), rice (Gesch et al, 1998) and several other plant species, including trees (Van Oosten and Besford, 1996), in response to elevated [CO 2 ]. Direct comparisons of the effects of sugar feeding and elevated atmospheric [CO 2 ] on transcription of several nuclear and chloroplast genes involved in photosynthesis have been undertaken in tomato (Van Oosten and Besford, 1994).…”

“…The similar result was also observed in Norway spruce (Urban et al 2003). Furthermore, Zhang et al (2008) has demonstrated that RuBP regeneration limitation is predominant within the two limitations. However, it is not known whether such mechanism of photosynthetic acclimation operating in rice is speciesspecific or universal.…”

“…---Photosynthetic measurements with calculation of maximum in vivo carboxylation rate (V cmax ) and maximum in vivo electron transport rate (J max ), and determinations of RuBP and sucrose contents as well as sucrosephosphate synthase (SPS) activity were made as described by Chen et al (2005) and Zhang et al (2008). RuBPCO and its activase contents were measured with a protein detector enzyme-linked immuno-sorbent assay (ELISA) kit, ABTS system (KPL, Gaithersburg, USA).…”

“…Obviously, the mechanism of photosynthetic acclimation in wheat is different from that in rice (cf. Yong et al 2007) where the photosynthetic acclimation is related to both RuBP carboxylation limitation and RuBP regeneration limitation and the latter is predominant one (Chen et al 2005, Zhang et al 2008). It appears that the mechanism for photosynthetic acclimation to EC treatment operating in rice is species-dependent but not universal.…”

“…(Sudo et al 2003). Moreover, a significant decrease in the Cyt f content observed in CO 2 -enriched rice leaves (Zhang et al 2008) means that the EC rice leaves had a lower RuBP regeneration capacity. Although the Cyt f content in EC wheat leaves was not measured, the basically unchanged J max (Fig.…”

Net photosynthetic rate (P N ) measured at the same CO 2 concentration, the maximum in vivo carboxylation rate, and contents of ribulose-1,5-bisphosphate (RuBP) carboxylase/oxygenase (RuBPCO) and RuBPCO activase were significantly decreased, but the maximum in vivo electron transport rate and RuBP content had no significant change in CO 2 -enriched [EC, about 200 μmol mol −1 above the ambient CO 2 concentration (AC)] wheat leaves compared with those in AC grown wheat leaves. Hence photosynthetic acclimation in wheat leaves to EC is largely due to RuBP carboxylation limitation.Additional key words: maximum in vivo electron transport rate; net photosynthetic rate; ribulose-1,5-bisphosphate carboxylase/oxygenase activase; RuBP regeneration limitation; sucrose-phosphate synthase; Triticum. --After long-term exposure to elevated CO 2 concentration (EC) leaf net photosynthetic rate (P N ) is often significantly lower in the plants grown at EC than that in plants grown in ambient air (AC) when measured at a same CO 2 concentration. This phenomenon is so called photosynthetic acclimation to EC (Xu et al. 1994). Usually, this acclimation has been almost entirely attributed to the decrease in active ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCO) (Jacob et al. 1995, Rogers and Humphries 2000, Pérez et al. 2007). Nevertheless, Chen et al. (2005 reported that the photosynthetic acclimation in rice leaves is related to both RuBP carboxylation limitation and RuBP regeneration limitation. The similar result was also observed in Norway spruce (Urban et al. 2003). Furthermore, Zhang et al. (2008) has demonstrated that RuBP regeneration limitation is predominant within the two limitations. However, it is not known whether such mechanism of photosynthetic acclimation operating in rice is speciesspecific or universal. In order to answer the question the photosynthetic acclimation was investigated further in wheat.The Chinese CO 2 enrichment facilities were located at Xiaoji village (119°42'0"E, 32°35'5"N), Yangzhou city in Jiangsu Province, East China. In the experimental field, there were six rings of 15 m diameter. Among them, three rings were sprayed with pure CO 2 as EC treatment, and the others were in the normal atmosphere as AC control. The distances between EC and AC rings were more than 90 m. Target CO 2 concentration in the centre of EC rings was about 200 μmol mol -1 above the AC. The EC treatment was made from emergence of wheat seedlings to harvesting. Seeds of wheat (Triticum aestivum L.cv. Ningmai 9) were sown in mid November. The cultivation of wheat was performed with typical agronomic management techniques for this region.---Abbreviations: C i -internal CO 2 concentration; Cyt -cytochrome; J max -maximum in vivo electron transport rate; P N − net photosynthetic rate; RuBP -ribulose-1,5-bisphosphate; RuBPCO -ribulose-1,5-bisphosphate carboxylase/oxygenase; SPS -sucrosephosphate synthase; V cmax -maximum in vivo carboxylation rate.
