Single spore isolation of fungi

Fungal Diversity 01/1999; 3.


W.H. (1999). Single spore isolation of fungi. Fungal Diversity 3: 29-38. Methods to isolate fungi from single spores are outlined. These methods are specifically designed for mycological laboratories which are not necessarily well funded. Therefore, they involve a simple procedure, are relatively inexpensive, and most importantly effective. Furthermore, only basic equipment is required. By using these methods, most fungi, with the exception of those that do not germinate on artificial medium, can be isolated. Some approaches are suggested to prevent mite infestations and to reduce the risk of bacterial contamination.

    • "For the RNA extraction, single-spore isolates were obtained from the same ascoma of C. maritima from Paraíso Beach following a technique described by Choi et al. (1999). Whereas for the quantitative reversetranscription (RT) PCR, single-spore isolates from Pico de Oro Beach, Paraíso Beach, and Boca del Río Beach were obtained in addition to those from Paraíso Beach.

    • "C. canescens was recognized by its typical growth with cercosporin production (Daub, 1982) along with typical conidia and conidiophores (Ellis and Martin, 1882). In a few cases isolations were made from the infected tissues and culture was further purified by single spore isolation (Choi et al., 1999). Spore producing isolates of C. canescens were deposited in Microbial Type "

    • "The inoculated plates of PDA were incubated for 7-9 days at room temperature 25 0± 2 0 C. The colonies of the fungus were obtained within 8 days after inoculation. The pure cultures of the isolates were obtained using single spore isolation method described by Choi et al. (1999). The isolates were incubated on 2% potato dextrose agar (PDA) medium. "

    ABSTRACT: The Chestnut (Castanea sativa Mill.) population in India is confined to the northern part of the country, which is continuously destroyed by natural (diseases/pests) and anthropogenic disturbances. Chestnut diseases like cankers and blight are mainly caused by fungi. Attempts were made to isolate the important fungal pathogen of chestnut trees. We isolated fungal isolates from samples of infected chestnut trees, which are confirmed as a new species of the genus Cytospora, family Valsaceae, with unique morphological and molecular characters. The initial identification of the fungus was based on morphological characters, and later confirmed by molecular studies. The phylogeny of the fungus was determined by rDNA-based phylogenetic markers ITS (Internal Transcribed Spacers) with the help of phylogenetic tools and were used for molecular identification and differentiation of the fungus. Phylogenetic analysis of the unknown fungus showed isolates reside in a clade separate from other species of genus Cytospora. Cytospora castanae sp. nov., therefore, is a new species of the genus Cytospora, witnessed by its morphological and molecular characters.
