Item Microorganisms associated with some selected leafy vegetables sold in some markets in Ilorin, Kwara State(Department of Biological Sciences, Faculty of Science, Bayero University, Kano., 2014) Olahan, Ganiyu S.; Garuba, Taofeeq; Adeyemi, Sherif B.; Olahan, S. A.Microorganisms associated with some commonly consumed leafy vegetables in popular markets of Ilorin, kwara State were investigated. The leafy vegetables were Amaranthus hybridus, Brassica oleraceae and Telfairia occidentalis. Seven species of bacteria were isolated namely Escherichia Coli, Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Enterobacter aerogenes, streptococcus faecalis and Micrococcus luteus. Six species of fungi were equally isolated from some of the same leafy vegetables namely Aspergillus niger, A. Flavus, Rhizopus stolonifer, Neurospora sitophila, penicillium chrysogenum and Mucor racemosus. The isolates which are pathogenic might have arisen from conditions in the field and gardens where the leafy vegetables were grown, during transportation of the leafy vegetables to the market or as a result of the filthy environment in the markets where the leafy vegetables were obtained for this study. Therefore there is a great need for increased awareness on environmental hygiene in those fields and gardens and the market as well as sensitization of the farmers and traders on the need to adopt the modern technologies of transporting, storing and handling leafy vegetables.Item Molecular Characterisation of Potential Crop Pathogens Associated with Weeds as Endophytes in Unilorin Plantations, Nigeria(College of Science for WomenUniversity of Baghdad, 2022) Lateef, Azeez A.; Garuba, Taofeeq; Abdulkareem, Khadijah A.; Olayinka, Bolaji U.; Olahan, Ganiyu S; Adeyemi, Sherif B.; AbdulRahaman, AbdullahiItem Molecular Characterisation of Some Accessions of Corchorus olitorius(Faculty of Science, Federal University Birnin Kebbi, 2019) Abdulkareem, Khadijah A.; Sidiq, K. O.; Olayinka, Bolaji U.; Lateef Azeez A.; Garuba, Taofeeq; Adeyemi, Sherif B.; Sagaya, AbdulkadirNigeria has several native leafy vegetables that have been neglected. Corchorus olitorius belongs to this group. Genetic diversity was studied in five accessions of the plant using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS - PAGE). The aim was to determine the relationship (differences and similarities) among them. Sixteen polypeptide bands were obtained ranging from 12.29 KDa to 170 KDa indicating variations in the banding patterns of the accessions. The unweighted pair group method with arithmetic algorithm (UPGMA) dendrogram grouped the five accessions into three clusters with four groups showing 60% of the accessions in one group. The greatest similarity (96%) observed was between NGB00196 and NGB00194 while the lowest similarities (32%) NGB00191 and (40%) NGB00187. Adopting this technology can be useful in plant variety identification and registration of new plant varieties. NGB00191 was observed to be distantly related to the other accessions hence could be combined in a breeding programme.
