“…M cells fix atmospheric CO 2 into C 4 acids, which are passed through plasmodesmata to adjacent BS cells and decarboxylated. The BS is specialized with a permeability boundary to retain the released CO 2 and to exclude O 2 , thereby enhancing the Rubisco-initiated carbon reduction steps ( Nelson, 2010 ). BS cells seem to be developmentally related to the endodermal cells that surround the vasculature of the root and stem ( Slewinski, 2013 ).…”

“…Downloaded from https://academic.oup.com/jxb/article-abstract/65/13/3357/2877555 by guest on 18 March 2019 of functional properties (Brown and Smith, 1972;Edwards and Voznesenskaya, 2011), which must first be considered before analysing diversity in the identity and developmental origins of the characteristics that generate them. Based on the literature, the following functional properties of leaves are considered essential requirements for C 4 photosynthesis (Hattersley et al, 1977;Leegood, 2002;von Caemmerer and Furbank, 2003;Edwards and Voznesenskaya, 2011;Nelson, 2011). Note that these apply equally to all C 4 plants, whether or not they use distinct types of cells.…”

C4 photosynthesis is a complex physiological adaptation that confers greater productivity than the ancestral C3 photosynthetic type in environments where photorespiration is high. It evolved in multiple lineages through the coordination of anatomical and biochemical components, which concentrate CO2 at the active site of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). In most C4 plants, the CO2-concentrating mechanism is achieved via the confinement of Rubisco to bundle-sheath cells, into which CO2 is biochemically pumped from surrounding mesophyll cells. The C4 biochemical pathway relies on a specific suite of leaf functional properties, often referred to as Kranz anatomy. These include the existence of discrete compartments differentially connected to the atmosphere, a close contact between these compartments, and a relatively large compartment to host the Calvin cycle. In this review, we use a quantitative dataset for grasses (Poaceae) and examples from other groups to isolate the changes in anatomical characteristics that generate these functional properties, including changes in the size, number, and distribution of different cell types. These underlying anatomical characteristics vary among C4 origins, as similar functions emerged via different modifications of anatomical characteristics. In addition, the quantitative characteristics of leaves all vary continuously across C3 and C4 taxa, resulting in C4-like values in some C3 taxa. These observations suggest that the evolution of C4-suitable anatomy might require relatively few changes in plant lineages with anatomical predispositions. Furthermore, the distribution of anatomical traits across C3 and C4 taxa has important implications for the functional diversity observed among C4 lineages and for the approaches used to identify genetic determinants of C4 anatomy.

“…However, how Kranz leaf anatomy develops is largely unknown. Progress in C 4 engineering will require a better understanding of the developmental and evolutionary aspects of Kranz leaf anatomy (Langdale, 2011;Nelson, 2011;Wang et al, 2016).…”

The successful introduction of the C 4 pathway into C 3 crops would increase photosynthetic rates and crop productivity. However, our poor understanding of how Kranz leaf anatomy develops poses a great obstacle. In particular, the origin, development, and genetics of bundle sheath (BS) cells in C 4 plants are key points to elucidate. Here we report that Elymus tsukushiensis, a common C 3 grass of the subfamily Pooideae, contains chloroplasts in the mestome sheath (MS) cells of the leaf, unlike most MS cells of C 3 grasses. The chloroplasts are smaller than those of mesophyll cells. Immunogold localization showed that the chloroplasts and mitochondria of MS cells, respectively, accumulate ribulose 1,5-bisphosphate carboxylase/oxygenase and a photorespiratory enzyme, glycine decarboxylase, as in mesophyll cells. Thus, we suggest that the MS cells have weak photosynthetic and photorespiratory functions. This finding provides an insight into the development and evolution of C 4 -type BS cells in leaves of C 3 grasses. ARTICLE HISTORY
