Horticulture Research International, Wellesbourne, Warwick CV35 9EF, UK Photosynthetic limitations: use in guiding effort in crop improvement [Elektronische Daten] [Hamlyn G. Jones] Methods for identifying the important processes limiting crop production and especially photosynthesis are discussed with special reference to the use of transgenic plants with altered expression of the small subunit of ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco). Recent advances in the use of metabolic control analysis are reviewed and some restrictions in their application to crop improvement are discussed. Metabolic control and other sensitivity approaches are compared with the opportunities offered by ‘elimination' analyses where the contribution of one component is estimated from the change in assimilation rate when any limitation by that component is removed. It is concluded that although control or sensitivity analyses provide effective tools for describing the importance of component processes, especially when using transgenic approaches to generation of isogenic material, our present limited knowledge of the complex interactions between various metabolic pathways restricts the value of these approaches in guiding breeding effort. © 1995 Oxford University Press Environmental Interactions nationallicence Control coefficient nationallicence crop productivity nationallicence deviation index nationallicence metabolic control theory nationallicence photosynthetic limitations nationallicence plant breeding nationallicence transgenics nationallicence Journal of Experimental Botany Oxford University Press 46/special_issue(1995-09), 1415-1422 0022-0957 46:special_issue<1415 1995 46 exbotj https://doi.org/10.1093/jxb/46.special_issue.1415 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/jxb/46.special_issue.1415 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Jones Hamlyn G.
