T. Hoshino et al., EFFECTS OF TEMPERATURE ON GROWTH AND INTRACELLULAR PROTEINS OF NORWEGIAN TYPHULA-ISHIKARIENSIS ISOLATES, Acta agriculturae Scandinavica. Section B, Soil and plant science, 47(3), 1997, pp. 185-189
Growth of two groups of strains (group I and III) of the snow mould fu
ngus, Typhula ishikariensis from northern Norway, were studied in agar
and liquid culture. All strains could grow from -5 to 15 (group III)
or 20 degrees C (group I) and the optimum temperatures for growth were
4 or 10 degrees C, respectively. The group III strains showed irregul
ar growth as the hypal extensions were inhibited at 15 degrees C. Diff
erent temperature two-dimensional electrophoresis revealed that in the
group III strains some intracellular proteins were modified at the hi
ghest temperature. One of the reasons that group III strains did not g
row or showed irregular growth at 20 or 15 degrees C, was probably due
to protein aggregation or dissociation and thereby loss of vital prop
erties of intracellular proteins.
