Abstract: Seed coat color is a very important trait in oilseed type Brassica crops. Identification of the genes controlling the seed coat color is essential to the manipulation of these genes to develop new yellow-seeded germ plasm for oilseed breeding. The Brassica TTG1 and TT1 genes may be used to control seed color in plants.

Abstract: Seed coat color is a very important trait in oilseed type Brassica crops. Identification of the genes controlling the seed coat color is essential to the manipulation of these genes to develop new yellow-seeded germplasm for oilseed breeding The Brassica rapa Transparent Testa Glabra (TTG1) and Transparent Testa (TT1) genes may be used to control seed coat color in Brassica plants.

Abstract: A single base change in the Bn-FAE1.1 gene in the A genome and a two-base deletion in the Bn-FAE1.2 gene in the C genome produce the nearly zero content of erucic acid observed in canola. A BAC clone anchoring Bn-FAE1.1 from a B. rapa BAC library and a BAC clone anchoring Bn-FAE1.2 from a B. oleracea BAC library were used in this research. After sequencing the gene flanking regions, it was found that the dissimilarity of the flanking sequences of these two FAE1 homologs facilitated the design of genome specific primers that could amplify the corresponding genome in allotetraploid B. napus. The two-base deletion in the C genome gene was detected as a sequence characterized sequence region (SCAR) marker. To increase the throughput, one genome specific primer was labeled with four fluorescence dyes and combined with 20 different primers to produce PCR products with different fragment sizes.

Abstract: Provided are nucleic acid sequences from Brassica oleracea plants that encode enzymes involved in the synthesis of a glucosinolate molecule, including BoGSL-ALK, and BoGSL-ELONG, and methods of their use. The sequences find particular use in modifying the glucosinolate content of a plant. Also provided are primers for these two genes and a third key gene in the glucosinolate pathway, BoGSL-PRO, that can be used for developing molecular markers for assisted selection of plants with specific glucosinolate compositions. Additionally, compositions and methods for a simple, reliable and efficient PCR-based marker system, named sequence-related amplification polymorphism (SRAP), that finds use in the identification of coding sequences in the genome of a plant are provided.
