Genes for microsomal delta-12 fatty acid desaturases and related enzymes from plants

   
   

The preparation and use of nucleic acid fragments encoding fatty acid desaturase enzymes are described. The invention permits alteration of plant lipid composition. Chimeric genes incorporating such nucleic acid fragments with suitable regulatory sequences may be used to create transgenic plants with altered levels of unsaturated fatty acids.

A preparação e o uso dos fragmentos do ácido nucleic que codificam enzymes do desaturase do ácido fatty são descritos. A invenção permite a alteração da composição de lipid da planta. Os genes chimeric que incorporam tais fragmentos do ácido nucleic com seqüências regulatory apropriadas podem ser usados criar plantas transgenic com os níveis alterados de ácidos fatty unsaturated.
