Fig. 2.

C₄ cycle genes required for cell cooperation are cell-biased at SST. The C₄ cycle between BS and M cells relies on numerous enzymes expressed in either cell type. Heat maps of three boxes next to enzyme names represent the log₂-transformed BS/M expression ratio at the three developmental stages sampled (SST, maturing, mature). Each row indicates the results from a gene with the same proposed activity. Green signifies an M-biased ratio and blue represents a BS-biased ratio. Modified from Li et al., 2010 and detailed expression data is found in Supplementary dataset 2.
