The nearest flanking markers from the pre-selected common marker set are SNP100025953|F|0-27 and SNP100027611|F|0-18 (47.6 – 54.4 cM), which have syntenic blocks at Pv03 (38.4 – 39.1 Mbp), Va11 (12.5 – 17.4 Mbp) and Vr07 (39.4 – 43.5 Mbp). The effect of soil moisture on the proximate composition of Bambara groundnut (Vigna subterranea (L.) Verdc). A plant DNA minipreparation: Version II. The presence or absence (0/1) scoring of dominant DArT markers for each individual line in the segregating populations were converted into genotype codes, either (c,a) or (b,d), by comparison with the parental lines. Azam-Ali SN, Sesay A, Karikari SK, Massawe F, Aguilar-Manjarrez J, Bannayan M, Hampson KJ. 35.6 and 31.1% of the total DArTseq markers generated from populations IA and TD, respectively, could be mapped to the common bean genome using the marker sequence tag, with 55% of these matches occurring in genomic contexts expected to be transcribed. A comparison of the potential sequence matching location suggested that while the Va02 position gave the higher BLAST score due to a higher percentage of matching bases (57 out of 61 bases), the second best aligned position at Va08 with a slightly lower match (56 out of 61 bases) is the better alignment and agrees with the adjacent pre-selected common markers between 0 cM and 76.0 cM of this linkage group (Additional file 1: Fig S1a and b). The syntenic locations of the unassigned superscaffolds of aduki bean and mung bean genome have been omitted for simplicity (scaling: 1 cM to 0.5 Mbp). http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s12864-016-3393-8. The chromosome number is one of the primary basis of hybridization in agricultural crops as … Bi-allelic SNP markers were assigned as ‘a’, ‘h’ and ‘b’ as appropriate in each individual line according to the scoring pattern in both parental lines. Kang YJ, Satyawan D, Shim S, Lee T, Lee J, Hwang WJ, Kim SK, et al. 10 c. 20 d. 30. J Sci Food Agric. A total of 142 pre-selected common markers (Additional file 3: Table S1) meeting the selection criteria were added to the population-specific SNP markers for genetic linkage analysis using JoinMap v4.1 [18]. Cytological studies of wild diploid Arachis species in the same section of the genus (sect. Google Scholar. AUXIN RESPONSE FACTORs (ARFs) play important roles in auxin‐mediated growth and development, including fruit and seed development. Abnormalities in the division during meiosis or during spore wall formation result in 2n pollen. In the future, a completed and annotated genome sequence will become available through the efforts of the African Orphan Crops Consortium (AOCC) which includes bambara groundnut as one of its targets [10]. Alan Cann is a Senior Lecturer in the School of Biological Sciences at the University of Leicester and formerly Internet Consulting Editor for AoB.View all posts by AJ Cann. Bambara groundnut is cleistogamous, highly inbreeding and has 11 pairs of chromosomes (2n = 2x = 22) . Unweighted pair group method with arithmetic mean. Of these two sets of high quality selected DArTseq markers, 268 out of 298 (89.9%) markers showed the expected segregation pattern (1:2:1 or 1:1) in the IA F2 segregating population and 611 out of 739 (82.7%) markers segregated in the expected pattern in the TD F3 population (3:2:3 or 3:5) at a significance level of p < 0.05. The first intraspecific genetic map used a F3 segregating population (n = 73) derived from a cross between two domesticated forms of bambara groundnut (Tiga Nicuru and DipC), sharing the domesticated common parental line with the interspecific cross [8]. Table 1 shows the total number of cells analyzed, mitotic index values and the number of chromosome aberrations observed in bambara groundnut treated with The putative synthetic blocks identified across legume genomes would facilitate more effective comparison of gene order in the legume species and assist in the identification of the location of genes underlying QTL involved in controlling agronomic and yield traits in bambara groundnut, facilitating the marker-assisted selection process. Lavin M, Herendeen PS, Wojciechowski MF. Bambara groundnut [Vigna subterranea (L) Verdc.] These three species have 11 pairs of chromosomes and they were chosen not only because they have been sequenced and annotated (although they are at different levels of completion), but also because of the close evolutionary relationship among these legumes. The results from our study show that 2n pollen can be effectively used to obtain tetraploids interspecific derivatives, without the use of colchicine to double the chromosome number of triploids and avoid the laborious hexaploid route to obtain tetraploids. Growing monocultures of crop genotypes selected to respond to intensive inputs potentially makes major crops more vulnerable to pest and diseases and can lead them to perform poorly in low input systems. In our approach, two sets of DArTseq markers were used for the construction of the genetic maps; population-specific high quality SNP markers and pre-selected common ‘link’ DArTseq markers (as illustrated in Fig. Article  How many chromosomes would be in the zygote? et Greg. groundnut. A fluorescence in situ hybridization (FISH)‐based karyotyping cocktail … 2009. 1992;60:197–203. All authors read and approved the final manuscript. In line with expectations based on genetic relatedness, a higher percentage of markers showed good sequence homology hits with the Vigna genomes, with more than 45% of the bambara groundnut DArTseq markers locatable on the adzuki bean and mung bean genomes (DArTseq markers from IA population: 47.8% mapped to adzuki bean genome, 46.2% to mung bean genome; DArTseq markers from TD population: 50.2% mapped to adzuki bean genome, 48.0% mapped to mung bean genome), nevertheless, some were less informative as they were found to be homologous to the remaining superscaffolds within the genome assemblies which had not been assigned to chromosome locations in the sequenced species. Article  However, there is a possibility that the mapping algorithm has misidentifying the best match within the genome of the other species, or that the best match may not have been represented in the comparison species genome sequence.
