Model for mechanisms of divergent growth associated with NCAPG. Black boxes identify genes and gene products that interact with each other in the NCAPG-network (Figure 3B). Grey shaded boxes specify gene products which are encoded by genes from the global growth network (Figure 3A). Arrows indicate molecular interactions, dashed arrows indicate genetic effects, dotted lines indicate physiological effects and blocked lines indicate a decreased pathway activity. Graph adapted from  and the Kyoto Encyclopedia of Genes and Genomes (KEGG) (http://www.genome.jp/kegg/, pathway: vascular smooth muscle contraction, accessed: 06/20/2013).
