Abstract: Abstract: cDNA—AFLP was used to detect diferentially expressed genes during flower bud development of
male sterile an d fertile lines of cabbage an d broccoli. Expression profiles were generated around 26,000 cDNA frag—
ments(128 primer combinations).Transcriptional changes were observed for 24 cDNA fragments,from which,
1 3 were only expressed in fertile buds, while the other 1 1 were upregulated in fertile buds. Sequencing of a 300 bp
diferential fragment amplified by primer combination A16T15 revealed 89% similarity to the gene thioredoxin,
which is related to pollen development in the Brassica family.

Key words: Cabbage, Dominant male sterility, cDNA—AFLP, Diferentially expressed genes
