An object of the present invention is to clone a gene which is involved in synthesis of fatty acid having trans-11-, cis-13-conjugated double bonds from fatty acid having a double bone at position &#x394;12. The present invention provides a gene having any one of the following nucleotide sequences:

Genes participating in the synthesis of fatty acid having trans-11-,cis-13-conjugated double bond and utilization thereof

In order to obtain a crop which provides an increased storage lipid content in its seed, the activity of cytosolic pyruvate kinase of a seed is substantially lowered as compared with the endogenous activity of pyruvate kinase in the plant seed. Preferably, the activity of phosphoenolpyruvate carboxylase is substantially lowered as compared with the endogenous activity of phosphoenolpyruvate carboxylase in the seed. Thus the storage lipid content in the plant seed is increased.

Method for increasing storage lipid content in plant seed

An oilseed crop with altered amino acid composition and/or fatty acid composition is provided. The crop is prepared by introducing antisense gene of a seed storage protein into the oilseed crop.
