            RESEARCH PROJECTS

(a)

Accomplished:

1. Furano-coumarins in disease resistance and mild virus in plant disease control. Furano-coumarins (-secondary metabolite) was isolated and characterized in both healthy and virus-infected celery (Apiumgraveolens Mill D.C.).  Infected of celery plants with viruses induced the production of greater amount of furano-coumarins than virus – free plants. Also, prior infection of celery plants with mild strains of viruses suppressed leaf blight disease caused by a fungus – Septoria apicola.

2. Studies on the post-harvest fungal diseases and deterioration of some Nigerian crops.  Storage and rot fungi such as Aspergillus   spp., Penicillium spp; Botryodiploida thebromae, Fusarium spp; Macrophomina phaseolina; etc were found to be associated with sunflower (Helianthus annus) seeds, groundnut (Arachis hypogaea L.), wild mango (gbono) seeds, Africana yambean (Sphenostylis stenocarpa), Africana pear (Dacryodes edulis), and sweet potato (Ipomoea batatas).  The fungi caused various biochemical changes in their food composition.

3. Evaluation of some fungi in the remediation of crude oil and products in polluted soil.  Some soil-borne and edible fungi were identified to grow well in crude oil, automotive gasoline oil and spent engine oil, and to degrade the toxic hydrocarbons to less or non-toxic compounds.  The fungi include: Rhizopus sp; Aspergillus niger, A. flavus, pleurotus pulmonarius. P. tuber-regium and Lentinus squarrosulus.  Ammendment (with waste             cotton and saw dust) and bio-augumentation (with Pleurotus       polmunarius) of crude oil and products polluted soils supported germination and seedling growth of some crops.

4. Screening of indigenous plant extracts for the control of plant pathogens and diseases.  Some local plants vizly: Alchornea cordifolia, Annona muricata, Allium sativum, Garcina cola and Zingiber officinale extracts (water or ethanol) inhibited the growth and establishment of rot fungi (Aspergillus flavus, A.niger, Botryodiplodia theobromae, Fusarium solani, F.   oxysporium and Rhizopus stolonifer) of sweet potato (Ipomoea batatas).

5. Studies on the storage methods and fungi associated with storage rots of fruits.  This study primarily considered the various factors that affect the keeping of quality of fruits and to assess the magnitude of loss.  It also aimed at determining the causes of fruit deterioration in storage.

6. Studies on the use of some edible fungi in bioremediation of crude oil polluted environment. Enzymes produced by some fungi which are responsible for the degradation of toxic hydrocarbons into non-toxic substances were isolated and characterized.

7. Screening of soil-borne fungi for possible use as bioremediation agent. Some soil-borne fungi were screened and those with bioremediation potentials were identified.

8. Studies on fungal leaf spot of disease of potato in local and experimental farms in Rivers State. In this study, the fungal organisms responsible for the leaf spot disease of potato were identified and the effects of leaf spot disease on potato was also ascertained.

(b)

Research in progress/completed but not yet published:

1. Molecular characterization of microorganisms associated with some food crops, vegetables and fruits using Sanger sequencing.
2. The use of metagenomics to determine microbial community structures in plants and food crops such as: Dacryodes edulis (ube), Irvingia gabonensis (ogbono), Talinum fruticosum (water leaf), Cucumeropsis mannii (egusi), Telfairia occidentalis (Ugu), Chrysophllum albidium (africa star apple) and Persea americana (avocado).
3. Interaction between microorganisms in plants and the functional prediction of their genes
4. The use of shortgun metagenomics to determine the viral particles associated with Jatropha curcas (jatropha) and Cnidoscolus aconitifolius (chaya) plants.
