In Silico Identification and Comparative Genomics of Candidate Genes Involved in Biosynthesis and Accumulation of Seed Oil in Plants

Figure 4

Structure of FAD 3 (linoleoyl desaturase) gene in Arabidopsis (At2g29980), castor bean (29681.m001360), and two soybean homologs (Glyma01g29630, Glyma07g18350). Exon/intron numbers are conserved in FAD 3 while variation in sizes was observed in the first and last exons. SNP identified in the 6th exon of soybean homolog (Glyma01g29630) was reported to be associated with low linolenic acid content [17].
