C3、C4或天冬酸代谢（CAM）光合途径是植物性状变异的一个基本轴，在从基因组到生物群系的尺度上具有重要意义。了解这些途径在野生物种中的分布是理解光合作用进化模式和过程及其在大尺度生态过程中的作用（例如全球变化下生物群落组成的变化）的关键的第一步。C4光合作用在禾本科植物中最为普遍，约占所有C4物种的一半（Sageet al., 1999a）。这些植物的进化和生态学研究经历了文艺复兴时期在过去的7年,催化系统发育分析显示多个平行C4起源(如Christin et al ., 2007; Vicentini制作et al ., 2008; GPWG II, 2012),洞察C4物种的分布和组装的C4草原生物群落(爱德华兹&仍然,2008;爱德华兹和史密斯,2010;爱德华兹et al ., 2010),和努力将C4途径引入大米(Hibberd et al ., 2008;·冯·Caemmerer et al ., 2012)。C4光合作用是研究复杂性状进化的一个极好的模型，因为它有广泛的知识库来描述其生化基础、进化史和生态相互作用（Christin et al., 2010）。
C3, C4 or Crassulacean acid metabolism (CAM) photosynthetic pathways represent a fundamental axis of trait variation in plants, with importance at scales from genome to biome. Knowing the distribution of these pathways among wild species is a crucial first step in understanding the patterns and processes of photosynthetic evolution and its role in ecological processes at large scales (eg changes in the composition of biomes under global change). C4 photosynthesis is most prevalent in the Poaceae (grasses), which account for about half of all C4 species (Sageet al., 1999a). Research on the evolution and ecology of these plants has undergone a renaissance during the last 7 yr, catalyzed by phylogenetic analyses showing multiple parallel C4 origins (eg Christin et al., 2007; Vicentini et al., 2008; GPWG II, 2012), insights into the distribution of C4 species and assembly of the C4 grassland biome (Edwards & Still, 2008; Edwards & Smith, 2010; Edwards et al., 2010), and efforts to introduce the C4 pathway into rice (Hibberd et al., 2008; von Caemmerer et al., 2012). C4 photosynthesis is an excellent model for investigating complex trait evolution, because of the broad knowledge base describing its biochemical basis, evolutionary history, and ecological interactions (Christin et al., 2010).
