Summary

enlarge

Arabidopsis seeds viewed through a fluorescence microscope. Two show the fluorescent markers used to track inserted genes; the third is an unmodified, wild type seed, which appears dark.

Fatty acid desaturase genes are delivered to host plants in expressible form to provide lower saturated fatty acid content in seeds.

Description

The present invention relates to enzymes involved in lipid metabolism. In particular, the present invention provides coding sequences for Arabidopsis Desaturases (ADS), the encoded ADS polypeptides, and methods for using the sequences and encoded polypeptides, where such methods include decreasing and increasing saturated fatty acid content in plant seed oils.
