A new genomic DNA encoding a member of Gastrodia antifungal protein family is isolated and sequenced.This gene contains a 510 bp open reading frame and 531 bp promoter region without introns.Sequence analysis indicates that a 28 amino acids signal peptide exists at the N-terminal.It shows high sequence homology with the mannose-binding lectinsfrom Epipactis hellebo-rine, Listera ovata and Cymbidium hybrid.A putative TATA box and transcription start site is dete cted in the promoter region.
