Also, a complete lack of recombination across this region is reflected in the genetic map derived from a cultivated × wild cross (Lo et al., 2018; IT99K‐573‐1‐1 × TVNu‐1158; Figure S10), which indicates that the wild parent has the opposite orientation of the cultivated accession. A series of checks are carried out before and after the stitching to minimize the possibility of creating mis‐joins. There are approximately 4,000 seeds/lb (Woodruff et al., 2010), and there are about 60 lb/bushel of grain (Murphy, 1993). Two tightly linked genes coding for NAD-dependent malic enzyme and dynamin-related protein are associated with resistance to Cercospora leaf spot disease in cowpea (Vigna unguiculata (L.) Walp.). As nodulins play a key role in the establishment of symbiosis with Rhizobium bacteria (Legocki and Verma, 1980), perhaps different nodulin alleles are correlated with different rhizobial symbionts for the two subpopulations. Cowpea (Vigna unguiculata (L.) Walp.) Cowpea BES with more than 80% of the sequence length showing homology to known repeats were removed, otherwise the BES were kept but the repetitive region was marked using letter N. Self‐comparisons were conducted with the RepeatMasker processed sequences to further filter the cowpea‐specific repeat elements. The dashed lines indicate the bottom and top 1% of He and FST values, respectively. The publicly available genome sequence lays the foundation for basic and applied research, enabling progress towards the improvement in this key crop plant for food and nutritional security. SMRTbell libraries were annealed and bound to the P6 DNA polymerase for sequencing using the DNA/Polymerase Binding Kit P6 v2.0 (P/N100‐372‐700). The presently available data from one reference‐quality genome sequence and WGS short reads from 36 accessions are insufficient to create a comprehensive and reliable catalog of structural variants; additional high‐quality de novo assemblies will be required to accomplish those goals. Frequencies were calculated for 2 cM intervals and normalized to the total anchored scaffold size. Cowpea flowers are large and showy. This report presents 323 Mb of WGS and 497 Mb of BAC sequence information, a tool to simultaneously test 51 128 single nucleotide variants, and a high‐density genetic map providing coordinates for most of those sequences and variants. One interpretation could be that there has been selection for a preferred pod length in these materials. A decade of Tropical Legumes projects: Development and adoption of improved varieties, creation of market‐demand to benefit smallholder farmers and empowerment of national programmes in sub‐Saharan Africa and South Asia. The cowpea, which also includes black-eyed peas, is one of the most widely grown legume crops in the world and number one source of protein in the human diet in sub-Saharan Africa. The legume cowpea (Vigna unguiculata L.) is extensively grown in sub-Saharan Africa. Journal of Food Composition and Analysis. Resulting SMRTbell libraries were size selected using the BluePippin (Sage Biosciences) according to the Blue Pippin User Manual and Quick Guide. Gene models were predicted by homology‐based predictors, FGENESH+, FGENESH_EST (similar to FGENESH+, EST as splice site and intron input instead of protein/translated ORF), GenomeScan (Yeh et al., 2001), PASA assembly ORFs (in‐house homology constrained ORF finder) and from AUGUSTUS via BRAKER1 (Hoff et al., 2015). With a high SNP coverage of the genome and connections to cowpea genome sequences, this study provides the basis for a unified chromosome nomenclature for the cowpea research community. The peak of the distribution is 56, which represents the effective coverage. QTL Mapping of Ineffective Nodulation and Nitrogen Utilization‐Related Traits in the IC‐1 Mutant of Cowpea. Genetic diversity and structure of Iberian Peninsula cowpeas compared to world-wide cowpea accessions using high density SNP markers. The region extending from the beginning of the first hit to the end of the last hit was considered to define the centromeric region of each cowpea chromosome. The total number of unique 27‐mers in the range x = 2–10 000 is 31.381 × 109. Mukherjee (1968) studied the pachytene chromosomes and reported that the 11 bivalent complement, consisted of 1 short (19 µm), 7 medium (26-36µm), and 3 long (41-45 µm) chromosomes. The extra floral nectarines at the base of the corolla attract ants, flies and bees but a heavy insect is required to depress the wing petal and expose the stamen and stigma. The standard MagBead sequencing protocol followed the DNA Sequencing Kit 4.0 v2 (P/N 100‐612‐400), which is known as P6/C4 chemistry. (1990) could be due to incomplete removal of formaldehyde fixative prior to staining with Schiff's reagent, which binds to free aldehyde groups (Chieco and Derenzini, 1999).
