Abstract:

The protein of 'Lidongben' longan zygotic embryos during different development stages were separated and compared by IEF-SDS-PAGE technique. Flavanone 3-hydroxylase was one of differential proteins identified by MALDI-TOF-TOF/MS. Then F3H gene cDNA sequence was cloned from longan zygotic embryos using RT-PCR and RACE technique. A 1 404 bp full-length cDNA sequence was obtained. Analysis of F3H gene cDNA indicated that it encoded a peptide containing 365 amino acids. The nucleotide sequence comparison with the F3H gene of Citrus sinensis, Gossypium hirsutum and Pyrus communi showed that identity was all higher than 80%. The sequence was accepted and released by GenBank (Accession number:EF468104)。

Key words: longan, embryo, flavanone 3-hydroxylase, gene cloning, sequence analysis
