Polyphasic taxonomic characterization of nine Penicillium species from soil of different parts of India (original) (raw)
2021, Journal of Environmental Biology
Aim: Morpho-molecular analyses for taxonomic characterization of nine predominant Penicillium species present in the soil of different parts of India. Methodology: Fifteen Penicillium isolates were isolated from the soil samples collected from the experimental field of ICAR-Indian Agricultural Research Institute (IARI), New Delhi. Another twenty-six isolates were procured from Indian Type Culture Collection (ITCC), Division of Plant Pathology, ICAR-IARI, New Delhi which were isolated from the soil of different parts of India. Total 41 isolates were characterized following distinct macroscopic (colony texture, colony colour exudate production; soluble pigmentation; reverse coloration and mycelial growth) and microscopic observations (type of penicillus; shape of phialides; conidial shape, size and pigmentation). Molecular characterization was done using partial β-tubulin gene sequence which is considered an excellent marker in differentiating Penicillium species. Results: The morphol...
