TABLE 2.

Putatively functional sequences and pseudogenes obtained by cloning the PCR product from three different protocols: standard PCR, high-stringency PCR (with DMSO), and (RT–PCR)

	Putatively functional		Pseudogenes:
	Group 1	Group 2	Groups 3–8
Standard PCR	3	9	23
PCR with DMSO	18	1	0
RT–PCR	5	4	7

The eight groups represent well-supported clades in a maximum-likelihood tree, of which two are putatively functional (groups 1 and 2) and the rest are pseudogenes (Figure 2).
