Abstract: Ethiopia is claimed as the likely center of origin for okra [Abelmoschus esculentus (L).Moench], but few studies were conducted to assess the diversity of the crop in the country. Moreover, no attempt has been made to assess the diversity of okra genotypes for seed yield and related traits though the crop is known for the production of quality edible oil. Therefore, this study was conducted with the objectives of assessing genetic variability among okra genotypes for seed yield and...
Abstract: The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. The ABO and Rh blood groups varies worldwide and are not found in equal numbers even among ethnic groups. Therefore, the objective of the study was to estimate phenotypic, genotypic and allelic frequencies of ABO and Rh blood groups among students of Oromo, Amhara and Gurage ethnic groups in Geresu Duki preparatory school in Woliso town, Oromia, Eth...
Abstract: The feeder free culturing of pluripotent stem cells aims to eliminate the use of mouse embryonic fibroblasts (MEFs) as substrate during in vitro culturing. Here, the potential of fibronectin and vitronectin to keep stem cells undifferentiated was compared using two different stem cell lines (HUES1 and HUES7). Cells were cultured on vitronectin and fibronectin for 3 weeks. Results showed that cells cultured in fibronectin appear to adhere slightly well initially while those in vitro...
Abstract: CrV1, a polydisperse DNA virus (polydnavirus or PDV) gene contributes to the suppression of host immunity in Cotesia genus parasitoids. Its molecular evolution was analyzed in relation to levels of resistance in the sympatric host species. Natural selection for nonsynonymous substitutions (positive Darwinian selection) was observed at specific amino acid sites among CrV1 variants; particularly, between parasitoid strains immune suppressive and nonimmune suppressive to the main resi...
Abstract: Yam (Dioscorea spp.) is an important food security crop with economic, nutritional, and medicinal value. It is a source of carbohydrates for millions of people in tropical and sub-tropical regions of Africa, Asia, South America, the Caribbean, and the South Pacific Islands. Determining the appropriate parents for breeding programs is the most important decision that plant breeders must make to maximize genetic variability and produce excellent recombinant varieties. However, adequa...
Abstract: Entomopathogenic fungi have been explored as a potential biopesticide to counteract the insecticide resistance issue in mosquitoes. However, little is known about the possibility that genetic resistance to fungal biopesticides could evolve in mosquito populations. Here, we detected an important genetic component underlying Anopheles coluzzii survival after exposure to the entomopathogenic fungus Metarhizium anisopliae. A familiality study detected variation for survival among wild ...
Abstract: Endophytic entomopathogenic species are known to systematically colonize host plants and form symbiotic associations that benefit the plants they live with. The actin-depolymerizing factors (ADFs) are a group of gene family that regulate growth, development, and defense-related functions in plants. Systematic studies of ADF family at the genome-wide level and their expression in response to endophytic colonization are essential to understand its functions but are currently lacking ...
Abstract: Plants are master regulators of rhizosphere ecology, secreting a complex mixture of compounds into the soil, collectively termed plant root exudate. Root exudate composition is highly dynamic and functional, mediating economically important interactions between plants and a wide range of soil organisms. Currently we know very little about the molecular basis of root exudate composition, which is a key hurdle to functional exploitation of root exudates for crop improvement. Root exp...
Abstract: We have chosen the urine innurioglobulin M (IgM) as system to study glycoprotein biosynthesis and carbohydrate processing. Secreted IgM heavy chain (m) has five glycoasylation sites which location and structures have been determined. chain variable region (VH) ia involved in antigen binding, while the constant region (CH) is responsible for the effect or functions in which the carbohydrate plays an important role.
Genetic diversity OF PLASMODIUM falciparum IN APPARENTLY HEALTHY SCHOOL children in ORE, Osun STATE.
ABSTRACT Human behavioral genetic research aimed at characterizing the existence and nature of genetic and environmental influences on individual differences in cognitive ability, personality and interests, and psychopathology is reviewed. Twin and adoption studies indicate that most behavioral characteristics are heritable. Nonetheless, efforts to identify the genes influencing behavior have produced a limited number of confirmed linkages or associ...
ABSTRACT Faidherbia albida (Del.) A. Chev is a tree species native to Africa and the Middle East. It is an important agro-silvo pastural species owing to its morphological and physiological dynamics that mediate improvement of soil structure and fertility while offering several other benefits to farmers and the environment. Key among these is its reverse phenology, a phenomenon that allows the tree to compete minimally with crops while providing a favorable microclimate for their growth. It ...
ABSTRACT Despite the fact that virtually all households in Kenya grow maize over 60% of them are net maize buyers because they do not produce enough for their consumption. Kenya‘s current food supply situation and outlook give cause for serious concern. Maize is the main staple food averaging over 80% of total cereals (rice, wheat, millet and sorghum) in Kenya. Maize stocks are estimated to be depleted at all levels throughout the country. According to strategic grain bank report on food s...
ABSTRACT Blast disease (Pyricularia oryzae or Magnaporte oryzae) is a disease of the economic importance in rice, causing up to 100% yield loss. The aroma trait of rice grain encoded by the badh2 gene significantly increases its market value. Unfortunately, the aromatic IR97012-27-3-1-1-B (Supa234) line developed at IRRI is susceptible to Pyricularia grisea pathotypes. Improvement of IR97012-27-3-1-1-B (Supa234) rice has been carried out through introgression of R genes (Pi9 and Pita) at IRRI...
ABSTRACT Coffee is a small shrub which is a source of a stimulating beverage. It ranks as one of the world's major commodity crops and is the major export product of many countries including Kenya. Economic production of Arabica coffee in Kenya is greatly hindered by the Coffee Berry Disease (CBD) caused by Colletotrichum kahawae. Since the release of the resistant Ruiru 11 in 1985, efforts have been devoted to the improvement of the genetic base of resistance, but this has faced the problem ...
