The Department of Plant Science is one of the foundational Departments in the Faculty of Science, dedicated to excellence in teaching, research, and community service. The Department provides rigorous training in molecular biology, genetics, physiology, ecology, ethnobotany, plant pathology, Taxonomy and Biosystematics, and applied aspects of plants, preparing students to contribute meaningfully to crop improvement and development, environmental sustainability, and scientific advancement.

Vision

To be a leading centre of excellence in teaching and research in Plant Sciences, producing graduates who are globally competitive and locally relevant in addressing taxonomic, agricultural, ecological, and environmental challenges.

Our History

Plant Science, formerly called Botany option, was one of the three options introduced at the foundation of the Department of Biological Sciences in 1983. This programme has been graduating students since 1986/87 Session annually. The programme is designed for the award of degrees, at the end of the fourth year of study.

Plant Science places strong emphasis on practical works both in the field and laboratory. This led to the introduction of compulsory field work during the Rain Semester of three hundred levels (300L) and during the first semester of the 400Level. In addition, there is an all-year-round project work and seminar on literature review, in Pure and Applied areas of Plant Science where students are given opportunity to select course areas, according to their interest.

Our Objectives

  • To train graduates for job opportunity in Pharmaceutical, fermentation industries, Agricultural establishments, Forestry, Management of Botanical Gardens arboreta, Parks Researchers in Research Institute; and as Teachers/Lecturers in both Secondary and Tertiary Institutions.
  • To turn out entrepreneurial graduates in various fields of Plant Science who could be future employers of labour.
  • To provide a broad-based academic training upon which graduates of the programme can build to pursue degrees of M.Sc., M.Phil/Ph.D in any area of Plant Science.

Academic Programmes

The Department offers undergraduate and postgraduate programmes designed to equip students with the theoretical knowledge and practical skills required in plant biology, bryology, ethnobotany, taxonomy and plant systematics, ecology, conservation, biotechnology, breeding, and crop management. Students are exposed to hands-on learning through field courses, laboratory research, and innovative projects that align with global trends in plant sciences.

Research Areas

Research in the Department spans areas such as:

  1. Plant Breeding and Genetics
  2. Plant Taxonomy and Biosystematics
  3. Plant Physiology and Biochemistry 
  4. Ecology and Ecophysiology
  5. Plant Pathology
  6. Ethnobotany and Phytomedicine
  7. Plant Conservation
  8. Molecular Biology

Facilities for Student Training

The Department is well equipped with modern facilities to support research and teaching:

  1. Teaching and Research Laboratories: for plant breeding, genetics, physiology, biotechnology, and pathology practicals.
  2. Herbarium: a well-curated collection of preserved plant specimens for taxonomy, biodiversity, and ecological studies.
  3. Greenhouse and Screen House: for controlled plant growth, breeding experiments, and stress-tolerance research.
  4. Biome and Field Trial Sites: serving as outdoor learning and research environments for ecological and crop studies.
  5. Lecture Halls and Classrooms: conducive spaces for interactive and effective teaching.

Dr Roseline Tolulope FEYISOLA is a Senior Lecturer and researcher in Plant Breeding and Genetics, with expertise in crop improvement, field evaluation, Plant tissue culture and genetic studies of maize, cassava, tomato and other food crops. She earned her PhD in Plant Breeding and Genetics in the year 2016, building on a strong foundation of research in maize productivity and resilience to Sitophilus zeamais (maize weevil) under diverse agro-ecological conditions. She is currently serving as the Acting Head of the Department of Plant Science (Botany), Olabisi Onabanjo University, Ago-Iwoye, Ogun State, Nigeria.

Her research focuses on the development of high-yielding and stress-tolerant crop varieties, with special interest in maize breeding, disease resistance, and abiotic stress adaptation. She has more than twenty-eight publications in national and international reputable journals, and has contributed to advancing knowledge in plant genetics through teaching, mentoring, and collaborative projects.

Dr Feyisola is passionate about applying plant breeding research to improve food security and sustainable agriculture in Sub-Saharan Africa. Her long-term goal is to strengthen research capacity in plant breeding, genetics and molecular biology while promoting innovations that address farmers’ needs and global food challenges..

In her capacity as Acting Head of Department, she oversees academic administration, curriculum development, staff coordination, and student mentoring. She is committed to fostering a culture of academic excellence, collaborative research, and innovation within the Department. Her leadership is directed toward strengthening the Department’s visibility and expanding its contributions to solving local and global crop challenges.
