actino- + -mycete

Examples

  • Hippophae possesses a strong capacity to fix atmospheric nitrogen in its root nodules when associated with the actinomycete, Frankia.

    Chapter 10

  • The avermectins are a mixture of natural products produced by a soil actinomycete, Streptomyces avermitilis.

    Chapter 8

  • Hippopha possesses a strong capacity to fix atmospheric nitrogen in its root nodules when associated with the actinomycete, Frankia.

    Chapter 26

  • In-vitro nitrogen fixation by two actinomycete strains isolated from Casuarina equisetifolia nodules.

    Chapter 13

  • As discussed previously, the root hairs of most casuarina species are invaded by the filamentous soil actinomycete, Frankia.

    3. The Plants

  • The nitrogen that the actinomycete in the nodules fixes enables the casuarinas to grow well in soils that otherwise would be too deficient in nitrogen to sustain plant growth.

    1. Introduction

  • Casuarina trees form root nodules in symbiotic association with the soil actinomycete Frankia that fixes atmospheric nitrogen.

    1. Introduction

  • Nitrogen fixation by actinomycete-nodulated angiosperms.

    Chapter 13

  • Casuarinas belong to a group of more than 170 species of actinomycete-nodulated woody plants that fix atmospheric nitrogen.

    1. Introduction

  • The Frankia actinomycete that forms the symbiosis with casuarinas is found naturally in soils where casuarinas are native.
