Jatropha curcas L. is peculiar treasured tree species for its uses and considerable economic potential as a biofuel plant. Propagation using seeds is limited by low viability and germination hence unable to provide high quality planting material for sustainable use. To achieve mass production of J. curcas, regeneration from leaf discs and petioles using different treatments of plant growth regulators (PGRs) including 6-... Read more.

Cassava (Manihotes culenta Crantz) is among major food and income security crops in sub-Saharan Africa. However, high seed dormancy and delayed germination limit seed propagation. Using traditional stem cutting causes loss of superior genotypes and decreases productivity as a result of low multiplication ratio (1:10) and viral and bacterial diseases.Thus, the aim of this study was to optimize and screen efficient in...

Legumes have been used as food by indigenous people of Africa yet their full potential as food sources has not been completely realized. With modern technologies such as marker-assisted selection and mutational breeding, there is scope for rapid improvement of germplasm in these underutilized species. One approach is to induce genetic mutations through irradiation of plant tissues with neutrons or gamma rays generating... Read more.

The discovery of RNA interference by Fire and Mello has opened up a new arena for research in molecular biology. The interfering RNAs (iRNAs) are 21-23 nucleotide RNA duplexes, which have the ability to reduce or abolish gene activity, and this property is being used in reverse genetics. Dicer and RISC (RNA-induced silencing complex) play important role in mechanism of RNA interference. The specificity, efficiency and... Read more.

Genetic diversity assessment of genetic resources maintained at Gene-Banks has important implication for future improvement, conservation and collection activities. However, such information is not available for sesame collected by IBC, Ethiopia. Inter simple sequence repeat (ISSR) marker was used to assess the level of genetic diversity, genetic structure and genetic distance, and to indirectly estimate the level of... Read more.

Biodegradation is the chemical breakdown of materials by a physiological environment. The term is often used in relation to ecology, waste management and environmental remediation. A specific gene from bacteria is identified and sequenced which has the capacity of oil degradation without any obvious strain specific discrimination using a combination of PCR and hybridization. The parameters of biodegradation that is... Read more.

The identification of a microbial isolate to genus level only amounts to a partial characterization of the isolate, but this can tell us a lot about that organism. Knowing the species allows the laboratory access to the body of knowledge that exists on that species. Identification schemes using phenotypic characteristics such as colony and cell morphology, Gram reaction and other staining characteristics, nutritional... Read more.

The Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov) causes extensive economic damage to wheat (Triticum aestivum L.) in most wheat growing regions of the world. Control of RWA using systemic insecticides is expensive and pollutes the environment therefore the most effective method of RWA control is the development of RWA resistant cultivars. This study was initiated to determine inheritance of RWA resistance in a... Read more.

Some nutrients in livestock feed may not be fully digested by animals own digestive enzymes, and hence important nutrients are unavailable to the animal. Although, supplementation of enzymes to farm animals has shown to increase the digestibility of poorly digested diets to a much greater extent. By targeting specific anti-nutrients in certain feed ingredients, feed enzymes allow especially pigs and poultry to extract... Read more.

Enzymes are substances produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction. Amylases are a class of hydrolytic enzymes, widely spread in nature having varied application in different industrial processes and constitute a class of industrial enzymes. Fungal amylases have been widely used for the preparation of oriental foods. In spite of the wide distribution of amylases... Read more.
