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. The internode length trait data was recorded in mm for the average length of the fourth internode measured for the five longest stems per plant at harvest. Food Chem. DArTseq markers (as identified by the sequence tags) found in both bambara groundnut populations were mapped to common bean, adzuki bean and mung bean genomes using CLC Genomic Workbench v8 (Qiagen). An alternation of generations means the plant, in this case the peanut, switches between the haploid (n) and diploid (2n) stages during its life. It is a recent allotetraploid, most probably resulting from the hybridization of two wild species followed by natural chromosome duplication (Halward et al., 1991; FM developed the TD population and helped to draft the manuscript. A DArT Array-based UPGMA genetic distance analysis grouped the two parents into different sub-sections based on a previous population structure analysis [9], which has made these two crosses useful in unravelling our understanding of the domestication events in bambara groundnut and the genetic control of a number of morphological and physiological traits.

A fluorescence in situ hybridization (FISH)‐based karyotyping cocktail … A test using the QTL location of an agronomic trait in one of the bambara groundnut maps allowed the corresponding flanking positions to be identified in common bean, mung bean and adzuki bean, demonstrating the possibility of identifying potential candidate genes underlying traits of interest through the conserved syntenic physical location of QTL in the well annotated genomes of closely related species. II. The authors declare that they have no competing interests. Most of the work on the chromosomes of the groundnut has been done at the somatic metaphase, which has only result- ed in karyotyping them in a routine fashion (Husted 1931, The cultivated species is made up of two genomes A and B. 3a). Using a combination of population-specific and pre-selected markers, two framework genetic maps were constructed from the two crosses; the genetic map of IA: from 263 F2 lines of IITA686 x Ankpa4 gave 11 linkage groups comprising of 223 markers and covered 1,395.2 cM and the genetic map of TD: from 71 F3 lines of Tiga Nicuru x DipC gave 11 linkage groups consisting of 293 markers and covered 1,376.7 cM (Fig. 2009;19:1639–45.

The significance threshold of the LOD score was identified through permutation tests using 10,000 reiterations. However, little is known about NAC genes in peanut. Our preliminary results overlaying the location of within-species QTL onto sequenced genomes suggests that translation of information (and the generation of gene lists within a trait controlling locus) can be used in an attempt to identify candidate controlling genes for further analysis within the species of interest which has no genome sequence. (2012). Identifying the conserved synteny between underutilised species without complete genome sequences and the genomes of major crops and model species with genetic and trait data is an important step in the translation of resources and information from major crop and model species into the minor crop species. In this case, the second best match would be in favour as it is consistent with the syntenic physical locations of its flanking markers. 45, 51 Arabidopsis MNT/ARF2, an ortholog of peanut ARF2, is a negative regulator of seed size and weight by repressing cell division and organ growth. The analysis options were set to be default whereby the regression algorithm was used for IM and MQM mapping.

Three of the most abundant elements are non-autonomous, and two of these appear to harbour ‘hitchhiking’ ORFs, in one case with retrotransposon-related function, and in the other with a biological function that remains to be identified. Ahmad NS, Redjeki ES, Ho WK, Aliyu S, Mayes K, Massawe F, Kilian A and Mayes S. Construction of a genetic linkage map and QTL analysis in bambara grouudnut (Vigna subterranean (L.) Verdc.). The additional homologue information from the population-specific markers could help in further refining the target area underlying QTL. To increase the marker resolution in this region, more population-specific markers could also be mapped to the common bean genome (as shown in Fig. Biodiversity for food security and nutrition.

The first genetic linkage map of bambara groundnut was reported by Basu in 2007 using a F2 segregating population (n = 98) derived from an interspecific cross between the non-domesticated wild type (VSSP11) and a domesticated form (DipC). identified the syntenic blocks of soybean QTL compared to the mung bean genome [12]. What's the chromosome number of peanut gamete?-40-10-20-30. As an example, LG4 shared homology with P. vulgaris Chromosome 07 (Pv07), V. radiata Chromosome 08 (Vr08) and V. angularis Chromosome 06 (Va06). PubMed  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. Bambara groundnut is cleistogamous, highly inbreeding and has 11 pairs of chromosomes (2n = 2x = 22) . (XLSX 45kb). ), rice (Oryza sativa) and maize (Zea mays) with thirty crops in all accounting for around 95% of total calories consumed [1, 2]. As this syntenic mapping approach is achieved through a cross-species comparison, we have been conservative in terms of mapping stringency so that the possibility of having more than one single good match location for a particular bambara groundnut marker sequence tag in the query genome was minimised. Within the Papilionoid legumes, peanut belongs to the Dalbergioids, a clade separated from most other economically important legumes (peas and beans) by an estimated 55 million years of evolution. c A simplified summary of the pseudo-physical map of bambara groundnut using the syntenic locus information from common bean (Pv), adzuki bean (Va) and mung bean (Vr) across the linkage groups of bambara groundnut genetic Map IA (based on chromosome number). Therefore, for cases where the genetic location and comparative syntenic position did not match with flanking markers, we manually used BLAST to determine whether the marker was likely to be a genuine breach of conserved synteny or whether other syntenic target sites might exist.

From these comparisons we identify conserved synteny blocks corresponding to the Linkage Groups (LGs) in bambara groundnut genetic maps and evaluate the potential to identify genes in conserved syntenic locations in a sequenced genome that underlie a QTL position in the underutilised crop genome. Dimensions of need: An atlas of food and agriculture. The ability to translate trait information from model and major crops species to underutilised crops is important to be able to fully exploit available resources, effectively developing research simultaneously into a complex of species, rather than a single species in isolation. Alcivar A, Jaconson J, Raingo J, Meksem K, Lightfoot DA, Kassem MA. Article  Schematic representation of our overall approach in constructing genetic maps of Population IA and TD having informative common markers from pre-selection. The current coincidence of the QTL in soybean and bambara groundnut for internode length needs further investigation and the gene content within the target region between species of interest is by no means guaranteed to be the same, although the closer the species are related taxonomically, the more likely it is that they will have similar gene content in the regions of conserved synteny. It is difficult to distinguish Brassica chromosomes as they are small and morphologically similar. The inheritance of pod- and seed-number traits (PSNT) in peanut (Arachis hypogaea L.) is poorly understood. Rome: Banson; 1995. p. 21–4. An initial QTL analysis was carried out on trait differences observed for growth habit, maturity and yield production [7]. When is Botany criminal? Collectively, the finding of a predicted soybean internode length QTL (located through the mung bean genome) is in accordance with our bambara groundnut internode length QTL study and has demonstrated that our approach could be adopted in other minor and underutilised species, both to translate existing information in more studied species and to identify de novo candidate lists. CAS  No consensus legume chromosome number of 5 has been proposed to date, although Medicago's basic chromosome number of 6 could be close to an ancestral chromosome complement. Brough SH, Azam-Ali SN, Taylor AJ. A total of 96 DArTseq markers from an initial pool of 142 pre-selected common markers were used. Exploring the potentials of underutilised and minor crops to contribute to agricultural biodiversity may also help agricultural production to cope with the effects of climate change, through improving the resilience of future agricultural systems, using crops that have been selected in-field for millennia under low input agriculture. This intraspecific map was constructed from 29 SSR and 209 DArT Array markers covering 608.6 cM in 21 linkage groups. This has further allowed us to observe that soybean Internode Length 1–4 QTL falls within this bambara groundnut QTL conserved synteny region.
