Figure 5.

Schematic illustration of a model for the relationship among Ccm1, Pmp1, 51 low-CO₂ inducible genes, and 58 Ccm1-regulated genes. Numbers of the genes are indicated in each group. Of these genes, Cah1 and Mca encoding carbonic anhydrases (CA); LciA, LciB, and Mrp1 possibly involved in Ci uptake; Pgp1, Gdh1, and Aat1 for the photorespiratory cycle (PR cycle); Sta2 and Sta3 possibly involved in the pyrenoid development, are highlighted. Previously known low-CO₂ inducible genes (Lci1 and Lci5) and chloroplast CA gene (Cah3) are also indicated.
