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.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
