Differential expression of tandemly arrayed genes. A. The PAD gene array of carboxylate transporter proteins (PAD1, Tb9277.5930, PAD2, Tb927.7.5940, PAD3, Tb927.7.5950, PAD4, Tb927.7.5960, PAD5, Tb927.7.5970, PAD6, Tb927.7.5980, PAD7, Tb927.7.5990, PAD8, Tb927.7.6000). Not shown is the unlinked PAD-like gene, Tb927.8.1650, which is expressed constitutively to low levels. B. A cluster of four genes encoding proteins of a major facilitator family. C. A cluster of genes with five to six transmembrane domains. Four genes are tandemly linked on chromosome 10 and the fifth, more divergent gene (Tb11.39.0005) is on chromosome 11.
