Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding novel delta-9 elongases along with a method of making long-chain polyunsaturated fatty acids using these delta-9 elongases in plants. The former comprises one or more multimedia agents contributed for use as components when developing more sophisticated systems. Fabric events engendered by the insertion or removal of hot-pluggable devices are handled by the isolation switch blade and \u201cevent storms\u201d on the Fibre Channel fabric are avoided.
