Expressed transcripts of the bracts and the normal leaves determined by cDNA-AFLP. An example showing selective amplification with eight different primer combinations and resolution of transcripts using cDNA-AFLP on an 8 % polyacrylamide denaturing gel and visualized by silver staining. 1, bract and 2, normal leaf. Bands indicated by numbers were differentially expressed transcripts, which were excised from the polyacrylamide gels and sequenced. The corresponding TDF numbers are on the right of the gel.
