Photosynthetic acclimation to elevated CO2 in relation to Rubisco gene expression in three C3 species.
Wheat (Triticum aestivum L. var. DL 1266-5), sunflower (Helianthus annuus L. var. MSFH 17) and mungbean [Vigna radiata (L.) Wilczek var. P 9072] were grown in field under atmospheric (360 +/- 10 cm3 m(-3), AC) and elevated (650 +/- 50 cm3 m(-3), EC) CO2 concentrations in open top chambers for entire period of growth and development. Photosynthetic acclimation to elevated CO2 was examined by com...
متن کاملDoes Chloroplast Size Influence Photosynthetic Nitrogen Use Efficiency?
High nitrogen (N) supply frequently results in a decreased photosynthetic N-use efficiency (PNUE), which indicates a less efficient use of accumulated Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). Chloroplasts are the location of Rubisco and the endpoint of CO2 diffusion, and they play a vital important role in photosynthesis. However, the effects of chloroplast development on phot...
متن کاملDifferential Allocation to Photosynthetic and Non-Photosynthetic Nitrogen Fractions among Native and Invasive Species
Invasive species are expected to cluster on the "high-return" end of the leaf economic spectrum, displaying leaf traits consistent with higher carbon assimilation relative to native species. Intra-leaf nitrogen (N) allocation should support these physiological differences; however, N biochemistry has not been examined in more than a few invasive species. We measured 34 leaf traits including sev...

متن کاملDoes ear C sink strength contribute to overcoming photosynthetic acclimation of wheat plants exposed to elevated CO2?
Wheat plants (Triticum durum Desf., cv. Regallo) were grown in the field to study the effects of contrasting [CO(2)] conditions (700 versus 370 μmol mol(-1)) on growth, photosynthetic performance, and C management during the post-anthesis period. The aim was to test whether a restricted capacity of sink organs to utilize photosynthates drives a loss of photosynthetic capacity in elevated CO(2)....
