“…Classical genetic studies described the V gene as a color enhancer or modifier gene which has multiple alleles with pleiotropic effects on color in flowers and seed coats (Prakken 1970(Prakken , 1974Bassett 1997;Bassett and Miklas 2007). Specifically, the [V] allele produces seed coats in which color ranges from pale violet to black depending upon other color genes present (Lamprecht 1932;Prakken 1934Prakken , 1972, whereas the [v] allele (in the presence of other color genes like T P C J G B) produces mineral brown seed coat (Lamprecht 1935;Bassett and Miklas 2007). Beninger et al (1999Beninger et al ( , 2000 affirmed that anthocyanin production is dependent on the V gene, since the presence of dominant genotypes [V] leads to anthocyanin accumulation, whereas recessive genotypes [v] lead to flavonol accumulation.…”

Key message Three genes associated with the seed coat color in a TU/Musica RIL population were located on a genetic map, and two candidate genes proposed to control black seed coat in the TU genotype were characterized. Abstract Seed coat color is an important characteristic of common bean (Phaseolus vulgaris L.) associated with the marketability of dry bean cultivars, quality and nutritional characteristics of seed, as well as response to pathogens. In this study, the genetic control of seed coat color in a recombinant inbred line population (175 lines) obtained from the cross 'TU' × 'Musica' was investigated. Phenotypic segregation fitted 1:1 for white vs. nonwhite, and 3:1 for brown versus black, indicating the involvement of three independent genes, one controlling white color and two (with epistatic interaction) controlling black color. Using a genetic map built with 842 SNPs, the gene responsible for the white seed coat was mapped on the linkage group Pv07, in the position previously described for the P gene. For the black seed coat phenotype, two genes were mapped to the beginning of chromosomes Pv06 and Pv08, in the positions estimated for the V gene and the complex C locus, respectively, by classical studies. The involvement of these two genomic regions was verified through two crosses between three selected RILs exhibiting complementary and dominant inheritance, in which the TU alleles for both genes resulted in a black phenotype. Two genes involved in the anthocyanin biosynthesis pathway were proposed as candidate genes: Phvul.006G018800 encoding a flavonoid 3′5'hydroxylase and Phvul.008G038400 encoding MYB113 transcription factor. These findings add knowledge to the complex network of genes controlling seed coat color in common bean as well as providing genetic markers to be used in future genetic analysis or plant breeding.

“…A recombinant inbred family was generated from a cross between Jamapa and Calima, a Mesoamerican and an Andean bean cultivar. Jamapa is a small and black seeded ( c ) [ 21 ] bean with an indeterminate growth habit ( Fin ) [ 22 ], pigmented hypocotyl ( Hpg ), purple flowers ( V ) [ 23 ] with pigmented stripes on the back of the standard, and pigmented calix and floral bracts. Calima is a large seeded mottled bean ( C ), with a determinate ( fin ) growth habit, white flower ( v ) and lacking pigmentation of the hypocotyl ( hpg ).…”

Punctuated Distribution of Recombination Hotspots and Demarcation of Pericentromeric Regions in Phaseolus vulgaris L.

High density genetic maps are a reliable tool for genetic dissection of complex plant traits. Mapping resolution is often hampered by the variable crossover and non-crossover events occurring across the genome, with pericentromeric regions (pCENR) showing highly suppressed recombination rates. The efficiency of linkage mapping can further be improved by characterizing and understanding the distribution of recombinational activity along individual chromosomes. In order to evaluate the genome wide recombination rate in common beans (Phaseolus vulgaris L.) we developed a SNP-based linkage map using the genotype-by-sequencing approach with a 188 recombinant inbred line family generated from an inter gene pool cross (Andean x Mesoamerican). We identified 1,112 SNPs that were subsequently used to construct a robust linkage map with 11 groups, comprising 513 recombinationally unique marker loci spanning 943 cM (LOD 3.0). Comparative analysis showed that the linkage map spanned >95% of the physical map, indicating that the map is almost saturated. Evaluation of genome-wide recombination rate indicated that at least 45% of the genome is highly recombinationally suppressed, and allowed us to estimate locations of pCENRs. We observed an average recombination rate of 0.25 cM/Mb in pCENRs as compared to the rest of genome that showed 3.72 cM/Mb. However, several hot spots of recombination were also detected with recombination rates reaching as high as 34 cM/Mb. Hotspots were mostly found towards the end of chromosomes, which also happened to be gene-rich regions. Analyzing relationships between linkage and physical map indicated a punctuated distribution of recombinational hot spots across the genome.

“…Studies have been carried out aiming to map the genetic control of tolerance to PHD [ 10 , 21 , 28 , 31 ] and of grain color of the species [ 35 – 37 ]. Expression of seed coat color is controlled by a sequence of multiple alleles of the P locus that show allelic interactions with the V locus [ 38 , 39 ], and they interact with alleles of seven other genes ( Gy , C , R , J , G , B , and Rk ) [ 35 , 36 ]. Bassett [ 37 ] proposed a list of 24 genes that can affect the seed coat color trait, and, in the case of carioca beans, which are characterized by cream-colored seeds with brown stripes, the pattern of the stripes and the coloring is controlled by the C locus [ 40 ].…”

Genome-wide association mapping reveals new loci associated with light-colored seed coat at harvest and slow darkening in carioca beans

et al. 2021

Background Common bean (Phaseolus vulgaris L.) is a legume whose grain can be stored for months, a common practice among Brazilian growers. Over time, seed coats become darker and harder to cook, traits that are undesirable to consumers, who associate darker-colored beans with greater age. Like commercial pinto and cranberry bean varieties, carioca beans that have darker seeds at harvest time and after storage are subject to decreased market values. Results The goal of our study was to identify the genetic control associated with lightness of seed coat color at harvest (HL) and with tolerance to post-harvest seed coat darkening (PHD) by a genome-wide association study. For that purpose, a carioca diversity panel previously validated for association mapping studies was used with 138 genotypes and 1,516 high-quality SNPs. The panel was evaluated in two environments using a colorimeter and the CIELAB scale. Shelf storage for 30 days had the most expressive results and the L* (luminosity) parameter led to the greatest discrimination of genotypes. Three QTL were identified for HL, two on chromosome Pv04 and one on Pv10. Regarding PHD, results showed that genetic control differs for L* after 30 days and for the ΔL* (final L*—initial L*); only ΔL* was able to properly express the PHD trait. Four phenotypic classes were proposed, and five QTL were identified through six significant SNPs. Conclusions Lightness of seed coat color at harvest showed an oligogenic inheritance corroborated by moderate broad-sense heritability and high genotypic correlation among the experiments. Only three QTL were significant for this trait – two were mapped on Pv04 and one on Pv10. Considering the ΔL, six QTL were mapped on four different chromosomes for PHD. The same HL QTL at the beginning of Pv10 was also associated with ΔL* and could be used as a tool in marker-assisted selection. Several candidate genes were identified and may be useful to accelerate the genetic breeding process.
