The free-pool sizes of amino acids involved in photorespiratory metabolism have been determined in leaves of Moricandia species during the post-illumination CO2 burst. The kinetics of the burst and the time to attainment of steady-state rates of dark respiration were much slower in the C3-C4
In order to study the location of enzymes of photorespiration in leaves of the C3-C4 intermediate species Moricandia arvensis (L.). DC, protoplast fractions enriched in mesophyll or bundlesheath cells have been prepared by a combination of mechanical and enzymic techniques. The activities of the
