Molecular cloning and characterization of the novel lection gene. Primers were designed based on conserved sequences of other lectin genes from Amaryllidaceae. A novel lectin gene was isolated from Zephyrathes grandiflora. The full-length cDNA of Zephyrathes grandiflora lectin was 955bp, containing an open reading frame (576bp) encoding a peptide of 191 amino acids. The gene was named as zga (Zephyrathes grandiflora agglutinin), with its encoding protein showing 59% similarity to GNA.

Positive rate was relatively high, and the foreign gene could also maintain in testicular tissue for a long time, it could still be detected in the tissue in 7 months after being injected. However. Deferent results could be gained when the detection were made with different primers on different sites of the recombinant plasmid. This could be explained by transgene lost when the foreign gene recombinated and integrated in heterogenetic cell, or transgene degradated by cell nucleases.
