Growth of the C4 dicot Flaveria bidentis: photosynthetic acclimation to low light through shifts in leaf anatomy and biochemistryJasper J L Pengelly
Research School of Biology, The Australian National University, Canberra, Australia
J Exp Bot 61:4109-22. 2010..Both mesophyll and bundle sheath conductance to CO(2) diffusion were greater in MI compared with LI plants. Despite being a C(4) species, F. bidentis is very plastic with respect to growth irradiance...
Nitrogen in cell walls of sclerophyllous leaves accounts for little of the variation in photosynthetic nitrogen-use efficiencyMatthew T Harrison

Nitrogen fertilization enhances water-use efficiency in a saline environmentKatherine C Martin
Division of Plant Sciences, Research School of Biology, The Australian National University, Canberra, ACT 0200, Australia
Plant Cell Environ 33:344-57. 2010..Instantaneous WUE estimates were supported by less negative foliar delta(13)C values for +N trees and scrub control trees. Thus, nutrient enrichment may alter the structure and function of mangrove forests along salinity gradients...
Light and CO2 do not affect the mesophyll conductance to CO2 diffusion in wheat leavesYoushi Tazoe
The Australian National University, Canberra, Australia
J Exp Bot 60:2291-301. 2009..In wheat, g(m) was independent of PFD between 200 and 1500 micromol m(-2) s(-1) and was independent of p(i) between 80 and 500 microbar...
Antisense reductions in the PsbO protein of photosystem II leads to decreased quantum yield but similar maximal photosynthetic ratesSimon A Dwyer
Research School of Biology, The Australian National University, Canberra ACT 0200, Australia
J Exp Bot 63:4781-95. 2012..It is suggested that these plants had a smaller pool of PSII centres, which are inefficiently connected to antenna pigments resulting in reduced photochemical efficiency...
