Other claims from this paper (10)
- Observation Afrothismia winkleri forms fleshy rhizomes with root tubercles that narrow into filiform roots with age.
- Observation The intracellular mycorrhizal fungus has distinct morphologies across plant tissues.
- Observation In filiform roots, fungal hyphae grow straight and vesicles occur on short stalks.
- Observation Hyphae are straight in root-tubercle epidermis and loosely coiled and swollen in rhizome tissue.
- Observation A separating rhizome cell layer allows only one or rarely two hyphal penetrations into each root-tubercle cortex.
- Observation Hyphae advance apically in root hypodermis as coiled spirals whose branches colonize inner cortex.
- Observation Hyphal coils degenerate into amorphous clumps in the inner root cortex.
- Observation Older root cortex deteriorates while other named root layers persist.
- Mechanism Authors interpret the mycorrhizal pattern as a fungus supplying and translocating carbon and nutrients in the plant.
- Observation Several features indicate that the endophyte is an arbuscular mycorrhizal fungus.
