Ne. Ivanushkina et al., SPECIFIC FEATURES OF MICROMYCETE COMPLEXES OF THE RHIZOSPHERE AND NODULES OF ACTINORHIZAL PLANTS, Microbiology, 63(5), 1994, pp. 511-515
The structure of micromycete complexes collected from yellow soil clos
e to the roots of five actinorhizal plants and their nodules was studi
ed. The characteristics of the species composition of micromycetes fro
m actinorhizal nodules and from soil (yellow soil) were demonstrated.
Representatives of the genus Cylindrocapron were found to be permanent
inhabitants of nodular microassociations. The effect of the pigment,
which is produced by actinomycetes of the genus Frankia and possesses
antibiotic activity, on the growth of micromycetes inhabiting the nodu
les of actinorhizal plants and the soil in their vicinity was studied.
It was established that the pigment stimulates the growth of micromyc
etes found commonly in the nodules and inhibits the growth of those is
olated from the soil.
