FIG. 3.

Sequence alignment of the regions corresponding to the 3′UTRs of the mRNAs, deduced from cDNA sequencing. 3′UTR-specific groups are indicated on the left and correspond to the clustering of identical or nearly identical sequences. Fourteen different 3′UTR groups were defined among the 28 sequences obtained from our 15-isolate panel. The different 3′UTR groups were designated according to the elicitin class, i.e., a for acidic, ha for highly acidic, and b for basic elicitins. For each 3′UTR, the boxed sequence represents the polymorphic region from which a 3′UTR-specific primer could be designed. The PFF309b 3′UTR sequence was so divergent that it could not be properly aligned. PFF309b was therefore not represented, but a specific reverse primer could be designed (a11-R).
