Twenty three polymorphic microsatellite markers were developed for citrus plant pathogenic fungus, Colletotrichum gloeosporioides, and used to analyze genetic diversity population structure of 163 isolates from four different geographical regions Ethiopia. These loci produced a total 118 alleles with an average 5.13 per marker. The information content values ranged 0.104 0.597 0.371. observed heterozygosity across all varied 0.046 0.058. gene among the 0.106 0.664. Unweighted...
Continuous storage root formation and bulking (CSRFAB) in sweetpotato is an important trait from agronomic biological perspectives. Information about the molecular mechanisms underlying CSRFAB traits lacking.Here, as a first step toward understanding genetic basis of sweetpotato, we performed genome-wide association study (GWAS) using phenotypic data four distinct developmental stages 33,068 single nucleotide polymorphism (SNP) insertion-deletion (indel) markers. Based on Bonferroni...
Genetic diversity and phylogenetic relationships among 252 cowpea (Vigna unguiculata (L.)Walp) accessions collected throughout the six geographical regions of Sudan were evaluated using simple sequence repeat (SSR) molecular markers. Eighteen (18) published primer pairs selected based on their informativeness, out which 16 gave reproducible results all tested. A total 129 alleles detected from loci with an average 8.1 per locus. Heterozygosity values ranged 0.01 to 0.13 occurrence 0.05 while...
Brachiaria (syn. Urochloa) grass is an important tropical forage of African origin that supports millions livestock and wildlife in the tropics. Overgrazing, conversion grasslands for crop production non-agricultural uses, introduction improved forages have threatened natural diversity Uganda. This study established a national collection ecotypes Uganda analyzed them genetic population structure using 24 simple sequence repeats (SSR) markers. These markers had high discriminating ability...
Abstract Background Ethiopian sheep living in different climatic zones and having contrasting morphologies are a most promising subject of molecular-genetic research. Elucidating their genetic diversity structure is critical for designing appropriate breeding conservation strategies. Objective The study was aimed to investigate genome-wide population eight populations. Methods A total 115 blood samples were collected from four populations that include Washera, Farta Wollo (short fat-tailed)...
Urochloa (syn.—Brachiaria s.s.) is one of the most important tropical forages that transformed livestock industries in Australia and South America. Farmers Africa are increasingly interested growing to support burgeoning business, but lack cultivars adapted African environments has been a major challenge. Therefore, this study examines genetic diversity Tanzanian accessions provide essential information for establishing breeding program Africa. A total 36 historical initially collected from...
Brachiaria is a tropical, warm-season grass native to Africa. It an extensively cultivated forage in the tropics with proven benefits on livestock productivity. well-known for high biomass production, animal nutrition, carbon sequestration, biological nitrification inhibition, soil conservation, and adaptation drought low fertility soils. However, use of fodder production Africa has been little explored largely due lack cultivars suitable different environments. The exploration natural...
Equine histoplasmosis commonly known as epizootic lymphangitis (EL) is a neglected granulomatous disease of equine that endemic to Ethiopia. It caused by Histoplasma capsulatum variety farciminosum , dimorphic fungus closely related H. c apsulatum. The objective this study was undertake phylogenetic analysis isolated from EL cases horses in central Ethiopia and evaluate their relationship with isolates other countries and/or clades using the internal transcribed spacer (ITS) region rRNA...
Knowledge about genetic diversity and population structure among goat populations is essential for understanding environmental adaptation fostering efficient utilization, development, conservation of breeds. Uganda's indigenous goats exist in three phenotypic groups: Mubende, Kigezi, Small East African. However, a limited their attributes hinders the development sustainable utilization goats. Using Goat Illumina 60k chip International Genome Consortium V2, whole-genome data 1,021 sourced...
Despite being the center of origin and genetic diversity, there has beenlimited application molecular markers in arabica coffee breeding inEthiopia. In this study, extent diversity relationships of48 elite lines from different geographical originswere evaluated using 14 SSR markers. The amplified 105 alleles ofwhich 104 are polymorphic with an average 7.4 per locus.The percent polymorphism Polymorphic Information Content (PIC)of were 98.81 0.79, respectively. geneticsimilarity coefficient...
Abstract Maize ( Zea mays L .) is a major staple crop in southern Africa and produced on millions of hectares. However, its yield greatly reduced by Striga spp, parasitic weed which causing US$ 7 billion losses annually. Use host resistance could be an effective way controlling to quantitative, mainly controlled additive gene action. Understanding the population structure genetic diversity therefore key designing breeding program targeting grain heterosis . The aim this study was determine...
Abstract BackgroundThere are over 100 Babesia species known to infect vertebrates with some of them being zoonotic. Local dog keeping practices enable extensive and intimate interactions between dogs, livestock, wildlife, their human owners, thus allowing the possibility dogs act as hosts for zoonotic parasites.Canine babesiosis, occur in Kenya causes a severe debilitating illness which compromises welfare capacity carry out role society. Published data on circulating among is limited....
Abstract One of the crucial public health problems today is emerging and re-emerging multidrug-resistant bacterial pathogens coupled with a decline in development new antimicrobials. Non-typhoidal Salmonella classified among international concern. To predict their multidrug resistance potentials, 19 assembled genomes (partial genomes) 23 non-typhoidal isolated at Yaounde abattoir between December 2014 November 2015 from live cattle (n=1), beef carcass (n=19), butchers’ hands (n=1) processing...
Abstract A study was conducted in all agro-ecological zones Tanzania to characterize the indigenous goat populations. Qualitative and quantitative data were collected from 688 randomly selected adult female goats. total of 220 households interviewed for description production system. Income generation meat primary objectives rearing goats across areas. More than 55% respondents grazed their animals freely communal lands where natural pasture chief feed resource. Mating mainly uncontrolled...
