text: The level 1 destination vector determines the position and orientation of each gene in the final construct. There are fourteen available level 1 vectors, which differ only by the sequence of the flanking fusion sites while being identical in the internal fusion sites. Hence, all vectors can assemble the same level 0 parts.
  As all level 1 vectors are binary plasmids, they are used for Agrobacterium mediated temporary expression in plants.
