Genomic analysis and identification of potential duplicate accessions in Burkina Faso cassava germplasm based on single nucleotide polymorphism

چکیده
Cassava adaptation to climate change and its resistance diseases are essential prerequisites for achieving food security in sub-Saharan Africa. The accessions collected from farmers’ fields very important because they can provide new sources of genetic variability that achieve this goal. In study, a panel 184 Burkina Faso was genotyped using 36 single nucleotide polymorphism (SNP) markers. markers presented with more than 6% missing data were removed the dataset remaining 34 166 retained diversity population structure assessment. average values expected heterozygosity (0.46), observed (0.58), polymorphic information content (0.36) indicated high within accessions. A complex through formation 17 clusters discriminant analysis principal components (DAPC) two Bayesian analysis. Out accessions, 79 unique multilocus genotypes (MLGs) 87 potentially duplicates. From MLGs, DAPC suggested eight while seven clusters. Clusters shaped by appeared be consistent higher probability assignment Principal Coordinate Analysis (PCoA) showed lack clustering according geographical origin. Information related breeding patterns geographic origin did not allow clear differentiation between molecular variance (AMOVA). results study will useful cassava germplasm conservation programs.

Background Single nucleotide polymorphism (SNPs) are considered as one of the underlying causes of male infertility. Proper sperm chromatin packaging which involves replacement of histones with protamines has profound effect on male fertility. Over 20 SNPs have been reported for the protamine 1 and 2.
