Since establishment in 1984, the department flourished with tireless efforts of faculties, staff and students. The course curriculum of the department has always been strong and forward looking. Syllabi have been revised regularly and the latest version was done with the introduction of semester system offering five special papers, namely Cytogenetics, Microbiology, Molecular Plant pathology and Fungal Biotechnology, Plant Biochemistry and Taxonomy of Angiosperms and Biosystematics.

    Physico-chemical analysis of rhizospheric soil, mycorrhizal association and root colonization of Mulberry (Morus alba L) plants grown in Kalimpong hills
    (University of North Bengal, 2014-03) Acharya, A.; Allay, S.; Ram, R. L.; Chakraborty, B. N.
    Morus alba L, known as white mulberry, is widely cultivated in the hills and its leaves are the major source of food for the silkwoms (Bombya mori L.) employed in the commereial production of silk. The physico-chemical properties of the soil where this plant is cultivated were analysed. The soils analysed had medium to high nitrogen content, but low to medium phosphorus and potash. Since mycorrhizal fungi can help in nutrient mobilization, AMF associated with the rhizosphere of the mulberry tree cultivated in RSRS, Kalimpong were extensively studied in relation to their population in soil, root colonization as well as their diversity. Predominant species of Glomus and few species of Gigaspora was determined. Histo-pathological studies of host roots showed the presence of vesicles and different kind of hyphal network. AMF spores were tried to be identified up to species level with the belp of standard keys. The result indicates that various species of AMF have established successful colonization with the host plant that will further support and help the plant for better growth and development
