Abstract
MAIN CONCLUSION We review the application and the molecular regulation of anthocyanins in colorful Brassica crops, the creation of new germplasm resources, and the development and utilization of colorful Brassica crops. Brassica crops are widely cultivated: these include oilseed crops, such as rapeseed, mustards, and root, leaf, and stem vegetable types, such as turnips, cabbages, broccoli, and cauliflowers. Colorful variants exist of these crop species, and asides from increased aesthetic appeal, these may also offer advantages in terms of nutritional content and improved stress resistances. This review provides a comprehensive overview of pigmentation in Brassica as a reference for the selection and breeding of new colorful Brassica varieties for multiple end uses. We summarize the function and molecular regulation of anthocyanins in Brassica crops, the creation of new colorful germplasm resources via different breeding methods, and the development and multifunctional utilization of colorful Brassica crop types.

Development of genome-specific SSR markers for the identification of introgressed segments of Sinapis alba in the Brassica juncea background. 3 Biotech 2022; 12:332.

Abstract
Sinapis alba L. (white mustard) is recognized for carrying host resistance against several biotic stresses including, Alternaria brassicae, which is responsible for blight disease in cultivated Brassica. However, another cultivated Brassica has a dearth for genetic resistance for these stresses due to its narrow genetic base. Therefore, we performed introgression of the genomic regions of S. alba into backcross progenies of B. juncea + S. alba somatic hybrids. These advanced generations with S. alba chromosomal segments are named B. juncea-S. alba introgression lines (ILs). In the present study, we developed the S. alba genome-specific microsatellites from the draft genome to track the S. alba genome introgressions and responsible regions for resistance to A. brassicae. For developing these SSR markers, the unique contigs of S. alba draft genome were identified through BLASTN with B. juncea, B. rapa, B. nigra, and B. oleracea reference genome assemblies, including mitochondrial and chloroplast genomes, and further used for marker development. Out of 403,423 contigs, we have identified 65,343 non-hit contigs of S. alba that yielded a total of 1231 genome-specific microsatellites, out of which 1107 were expected to produce a single allele upon amplification. Out of the total SSRs, 234 primer pairs were randomly picked from whole-genome and validated between B. juncea and S. alba genomes for their specificity. In the validation experiment, these markers gave a single amplicon into S. alba, while they did not amplify in B. juncea genome. Of these, 59 microsatellites were used to track S. alba introgressions in 80 BC2F3 lines. To the best of our knowledge, this is the first time that these two genetic resources are developed in the form of B. juncea-S. alba ILs and S. alba-specific markers. Therefore, both the resources unlock a new avenue of Brassica breeding for biotic and abiotic stresses along with quality traits.

Abstract
Seed coat colour is an important trait in Indian mustard. Breeding for seed coat colour needs precise knowledge of mode of inheritance and markers linked to it. The present study was focussed on genetics and development of functional markers for seed coat colour. F1s (direct and reciprocal) and F2 populations were developed by crossing two contrasting parents for seed coat colour (DRMRIJ-31, brown seeded and RLC-3, yellow seeded). Phenotypic results have shown that the seed coat colour trait was under the influence of maternal effect and controlled by digenic-duplicate gene action. Further, Bju.TT8 homologs of both parents (DRMRIJ-31 and RLC-3) were cloned and sequenced. Sequencing results of Bju.TT8 homologs revealed that in RLC-3, gene Bju.ATT8 had an insertion of 1279bp in the 7th exon; whereas, gene Bju.BTT8 had an SNP (C→T) in the 7th exon. These two mutations were found to be associated with yellow seed coat colour. Using sequence information, functional markers were developed for both Bju.TT8 homologs, validated on F2 population and were found highly reliable with no recombination between the markers and the phenotype. Further, these markers were subjected to a germplasm assembly of Indian mustard, and their allelic combination for the seed coat colour genes has been elucidated. The comparative genomics of TT8 genes revealed high degree of similarity between and across the Brassica species, and the respective diploid progenitors in tetraploid Brassica species are the possible donors of TT8 homologs. This study will help in the marker-assisted breeding for seed coat colour, and aid in understanding seed coat colour genetics more precisely.

Abstract
Chinese cabbage (Brassica rapa L. ssp. pekinensis) is one of the most widely cultivated and economically important vegetables in China. Constructing an effective genetic linkage map and mapping quantitative trait loci (QTLs) related to yield and leafy head morphology is of great importance for molecular breeding of Chinese cabbage. Using two diverse Chinese cabbage inbred lines, ZHB and G291, as parents, an F2 segregating population consisting of 240 individuals was prepared for genetic map construction and phenotype investigation in this study. The two parents are significantly different in both shape and size. Sixteen important agronomic traits of F2 individuals were investigated. A genetic map of 105 intragenic simple sequence repeat (SSR) markers distributed across 10 linkage groups (LGs) was constructed, which was 2034.1 cM in length and had an average inter-locus distance of 21.75 cM. We identified 48 QTLs for the tested important agronomic traits on the studied LGs, with LOD scores of 2.51–12.49, which explained the phenotypic variance of 3.41–26.66%. The QTLs identified in this study will facilitate further genetic analysis and marker-assisted genetic improvement of Chinese cabbage.

Abstract
Seed coat color is an important agronomic trait in Brassica rapa. Yellow seeds are a desirable trait for breeding oilseed Brassica crops. To identify quantitative trait loci (QTLs) that condition seed coat color in B. rapa, we used a population of recombinant inbred lines (RILs) derived from crossing 09A001, a standard rapid-cycling (RcBr) inbred line of B. rapa L. ssp. dichotoma with yellow seeds, with 08A061, an inbred line of heading Chinese cabbage with dark brown seeds. Using two phenotypic scoring methods, we detected a total of nine QTLs distributed on four chromosomes (Chrs.), A03, A06, A08, and A09, that explained 3.17 to 55.73% of the phenotypic variation for seed color. To validate the effects of the identified QTLs in the RIL population, chromosome segment substitution lines (CSSLs) harboring the chromosomal segment carrying the candidate QTL region from 08A061 were selected, and two co-localized major QTLs, qSC9.1 and qSCb9.1, and one minor QTL, qSC3.1, were successfully validated. The validated QTL located on Chr. A03 appears to be a new locus underlying seed coat color in B. rapa. These findings provide additional insight that will help explain the complex genetic mechanisms underlying the seed coat color trait in B. rapa.

Fine mapping of the major QTL for seed coat color in Brassica rapa var. Yellow Sarson by use of NIL populations and transcriptome sequencing for identification of the candidate genes. PLoS One 2019; 14:e0209982. [PMID: 30716096 PMCID: PMC6361427 DOI: 10.1371/journal.pone.0209982] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2018] [Accepted: 12/15/2018] [Indexed: 11/19/2022] Open
Abstract
Yellow seed is a desirable trait in Brassica oilseed crops. The B. rapa var. Yellow Sarson carry unique yellow seed color genes which are not only important for the development of yellow-seeded oilseed B. rapa cultivars but this variant can also be used to develop yellow-seeded B. napus. In this study, we developed near-isogenic lines (NILs) of Yellow Sarson for the major seed coat color QTL SCA9-2 of the chromosome A9 and used the NILs to fine map this QTL region and to identify the candidate genes through linkage mapping and transcriptome sequencing of the developing seeds. From the 18.4 to 22.79 Mb region of SCA9-2, six SSR markers showing 0.63 to 5.65% recombination were developed through linkage analysis and physical mapping. A total of 55 differentially expressed genes (DEGs) were identified in the SCA9-2 region through transcriptome analysis; these included three transcription factors, Bra028039 (NAC), Bra023223 (C2H2 type zinc finger), Bra032362 (TIFY), and several other genes which encode unknown or nucleic acid binding protein; these genes might be the candidates and involved in the regulation of seed coat color in the materials used in this study. Several biosynthetic pathways, including the flavonoid, phenylpropanoid and suberin biosynthetic pathways were significantly enriched through GO and KEGG enrichment analysis of the DEGs. This is the first comprehensive study to understand the yellow seed trait of Yellow Sarson through employing linkage mapping and global transcriptome analysis approaches.

Characteristics of Color Development in Seeds of Brown- and Yellow-Seeded Heading Chinese Cabbage and Molecular Analysis of Brsc, the Candidate Gene Controlling Seed Coat Color. FRONTIERS IN PLANT SCIENCE 2017; 8:1410.

Abstract
The proanthocyanidin (PA) is the main flavonoids which affect the seed coat color in Brassica species. In this paper, characteristics of color development and accumulation of flavonoids were analyzed in the seeds of brown-seeded (B147) and yellow-seeded (B80) heading Chinese cabbage (Brassica rapa L. ssp. Pekinensis). It is found that the content of phenolic compounds in B147 were significantly more than that of B80 by using dimethylaminocinnamaldehyde (DMACA) staining and toluidine blue O (TBO) staining. In previous studies, the locus associated with seed coat color has been mapped. The results of whole genome re-sequencing showed that there are large fragment deletions variation in the mapping region between the brown-seeded parent '92S105' and the yellow-seeded parent '91-125.' Based on the B. rapa genome annotation information, the TRANSPARENT TESTA GLABRA 1 (TTG1), is likely to be the candidate gene controlling seed coat color. A 94-base deletion was found in the 96th base downstream of the initiation codon in the TTG1 of yellow seed, thus, the termination codon TGA was occurred in the 297th base which makes the full length of TTG1 of yellow seed is 300 bp. Based on the differential sequences of TTG1 of brown and yellow seed, a functional marker, Brsc-yettg1, was developed to detect the variation of TTG1. Quantitative real-time PCR analysis of BrTTG1 in different tissues showed that expression levels of BrTTG1 was not tissue-specific. During the whole seed development period, the expression of BrTTG1 in B147 was higher than that of B80. The expression levels of four structural genes, BrDFR, BrANS, BrANR1, and BrANR2 in B147 were also higher than those in B80. The co-segregation molecular markers obtained in this report and TTG1 related information provide a basis for further understanding of the molecular mechanism of seed coat color in heading Chinese cabbage.
