“…Under conditions approximating those present during r-determinations at low light intensity (60 umol photon m2 s-' and 140 ,l C02/ 1), a somewhat greater propoftion of the initial 14C fixed occurs in the C4 acid fraction, especially in aspartate, indicating an (Tables II and V) show that no marked increase in CO2 assimilation via PEP carboxylase occurs in P. milioides and M. arvensis as the pCO2 is lowered from 310 to 140 Ml C02/ 1. These data are an additional indication that although the PEP carboxylase activity in vitro in leaf extracts of these C3-C4 intermediate species is about twice that in C3 leaf extracts (3,6,9,17), the activity in vivo remains as low as in C3 species.…”

“…ities of certain features of both species, such as the presence of bundle sheath cells with numerous centripetally arranged chloroplasts and mitochondria (9,17), suggest that a C4-type mechanism may be a factor in reducing photorespiration in M. arvensis. Leaves of this crucifer do accumulate substantial amounts of the C4 acid, malate, in the light (17).…”

“…For example, a rather well developed Kranz anatomy characterizes the C3/C4 grasses, Panicum and Neurachne (6,7,13), but the dicots Moricandia and some species of Flaveria, which have reduced PR and O2 sensitivity of AP similar to the C3/C4 grasses, have very little Kranz development (14,18). In the F2 and F5 progeny of the C3 X C3/C4 Panicum crosses some plants had well developed BSC with numerous organelles, but without F or PR which approach those ofthe C3/ C4 parents.…”

“…Among the species of Brassicaceae in which C 4 species have not yet been found, other C 3 -C 4 intermediate species have also been found within the genera Moricandia, Diplotaxis and Brassica (Apel et al, 1997). M. ar vensis, which was the first-reported C 3 -C 4 intermediate species in the Brassicaceae (Apel et al, 1978;Holaday et al, 1981), has attracted the attention of breeders because its traits can be introgressed into cultivated crops to improve their photosynthetic efficiency (Apel et al, 1984;Toriyama et al, 1987;Takahata, 1990;Takahata and Takeda, 1990;Kirti et al, 1992;Takahata et al, 1993;Razmjoo et al, 1996;Bang et al, 1996Bang et al, , 2002Bang et al, , 2007Ishikawa et al, 2003).…”
