Transcript profiling and gene characterization of three fatty acid desaturase genes in high, moderate, and low linolenic acid genotypes of flax (Linum usitatissimum L.) and their role in linolenic acid accumulation.

Abstract excerpt

Three genes encoding fatty acid desaturase 3 (fad3a, fad3b, and a novel fad3c) were cloned from four flax genotypes varying in linolenic acid content. Real-time PCR was used to quantify expression levels of the three fad3 genes during seed development. High amounts of both fad3a and fad3b transcripts were observed and reached their peak levels at 20 days after anthesis, except for fad3a from SP2047 where only low...
