Research Interest
Dr. Ajit Pratap Singh’s research interests focuses upon taxonomy, diversity & distribution, developmental biology, reproductive behaviour, multiplication, conservation, restoration and prospection of Pteridophytes & Bryophytes. Current state of our research is to prepare taxonomic account of these plants in the regions of Uttar Pradesh, western and eastern Himalayas, central India; reproductive behaviour & conservation of threatened ferns; large-scale propagation of ferns and prospection for potential insecticidal molecules from these plants; and futuristic approaches for study on nutritional profile and nutrients of significance in ferns for alternative food resources.
Research Summary:
Checklist of ferns and fern-allies of Uttar Pradesh. Taxonomic and account of ferns and fern-allies in most of the wild-life protected areas of Uttar Pradesh with a new record of Mircolepia speluncae, Selaginella ciliaris, Lygodium japonicum from Terai regions. Floristic account on ferns and fern-allies in some regions of Madhya Pradesh with a new record of Hymenophyllum javanicum, Ophioglossum gramineum. An account on the ferns and fern-allies in some regions of Arunachal Pradesh, Assam, Madhya Pradesh, Rajasthan and Uttarakhand is progressing. Developmental biology and reproductive behaviour of Anemia rotundifolia, Adiantum peruvianum, Lepisorus nudus, Cyathea spinulosa. Conservation of more than 70 live fern species in the fern-house and enrichment of about 8000 herbarium specimens in the herbarium. Prospection of about 102 species of pteridophytes & bryophytes yielded six plants showing potential mortality against cotton feeding insects. Development of a transgenic Tma-12 cotton against whitefly using a potential fern Tectaria macrodonta.
