Brassica Napus L

Rapeseed (Brassica napus L.) with substantial lipid and oleic acid content is of great interest to rapeseed breeders. Overexpression of Glycine max transcription factors Dof4 and Dof11 increased lipid accumulation in Arabidopsis and microalgae, in addition to modifying the quantity of certain fatty acid components. Here, we report the involvement of GmDof4 and GmDof11 in regulating fatty acid composition in rapeseeds. Overexpression of GmDof4 and GmDof11 in rapeseed increased oleic acid content and reduced linoleic acid and linolenic acid. Both qPCR and the yeast one-hybrid assay indicated that GmDof4 activated the expression of FAB2 by directly binding to the cis-DNA element on its promoters, while GmDof11 directly inhibited the expression of FAD2. Thus, GmDof4 and GmDof11 might modify the oleic acid content in rapeseed by directly regulating the genes that are associated with fatty acid biosynthesis.

Brassica Crops

Five genes have been identified in Brassica crops which control the level of synthesis of the fatty acid, erucic, in their seed oils. These genes, designated e, Ea, Eb, Ec, and Ed, act in an additive manner and result in erucic acid levels of < 1, 10, 15, 30 and 3.5, respectively. No direct evidence has yet been obtained to show that these genes are true alleles. Selected plants of the amphidiploid species Brassica napus L. with erucic acid contents of 7–8% and a genotype of EdEdee were reciprocally crossed with selected plants with erucic acid levels of [Formula: see text] and a genotype of Eaeee. Fatty acid analysis of F1 and backcross seed demonstrated that the genes Ed and Ea in the parents used were in the same genome and were truly allelic. Interspecific crosses were made between these B. napus parents and selected zero erucic acid plants of Brassica campestris L. (genotype "ee") to determine whether the genes Ed and Ea resided in the oleracea or the campestris genome of B. napus parents. Fatty acid analysis of F1 and backcross seed from these interspecific crosses suggest that the alleles of Ed and Ea are located on chromosomes of the oleracea genome.
