A cDNA clone (designated Repro) encoding profilin gene was isolated from rapeseed ( Brassica napus L. cv. canadian Tween) using RT-PCR technique. Sequence analysis showed 82% similarity to Zea mays L. ZmPro3, 85% to Arabidopsis AthPRF1, 82% to Nicotiana tabacum L. NTPRO, 81% to Oryza sativa L. profilin A. A new full-length cDNA was obtained by 5'-RACE and 3'-RACE techniques. Sequence analysis showed that the size of full-length cDNA is 672 bp which contains a major open reading frame of 134 amino, acids, 5' and 3' untranslated regions and a long Poly (A) tail. Northern blot analysis showed that the profilin gene is a pollen and anther specific gene.展开更多
