This study was undertaken to examine the degree of Kranz anatomy development in the species intermediate to C3 and C4 types (C3-C4) in Panicum, Neurachne, Flaveria, and Moricandia. In each genus, C3 and/or C4 species were used for comparison. Leaf transections from each species were examined by light and transmission electron microscopy. The percentages of leaf photosynthetic cell profiles partitioned to bundle sheaths were higher in C4 than in C3 species, while C3-C4 species tended to be in between. However, percentages for C3-C4 species in Moricandia and some C3-C4 Flaveria species were not greater than C3. When expressed on a cell profile area basis, C3-C4 species partitioned more photosynthetic tissue to bundle sheaths than C3 species in Moricandia, but not in Flaveria. Neurachne minor S. T. |
