Isolation and sequencing of the hazel FAD2-Ngene

摘要

The invention relates to the isolation from hazel (Corylus avellana L.) of the FAD2-N gene coding for the DELTA 12 desaturase enzyme of the microsomal fraction and, in particular, provides the nucleotide sequence and the deduced amino-acid sequence of the gene and provides for the use of the FAD2-N gene as a probe for the isolation of other plant desaturases. The invention also relates to the use of the FAD2-N gene for altering desaturase levels and consequently the fatty-acid composition of the plant.
