Q. Which statement(s) correctly describe(s) the interactions between plants and fungi?
The common interactions which are noticed between the fungi and plants include…
1. Plants are autotrophs, but fungi are heterotrophs.
2. Fungi secret digestive enzymes into their surroundings to get nutrients, but not plants.
3. Plants rely on fungi as mutualistic symbionts to get nutrients from soils. However, some fungi harm plants for their nutrients.
Example: The plant Arabidopsis thaliana depends on the fungi Colletotrichum tofieldiae for soluble phosphate in phosphate deficient soils.
4. The symbiotic relationship between plants and fungi can be noticed in two forms.
5. The beneficial fungi that colonize outside the plant are called ectophytic fungi.
6. The beneficial fungi which survive within the plant tissue without any harm are called endophytic fungi.
7. The fungi associated with the roots of plants are called ectomycorrhiza or ectomycorrhizal fungi.
Examples of plant beneficial fungi:
1. Some Trichoderma spp.
2. Some Penicillium spp.
3. Some Colletotricum spp.
4. Piriformospora indica, etc.
Examples of plant pathogenic fungi:
1. Fusarium oxysporum
2. Sclerotium rolfsii
3. Rhizoctonia solani
4. Colletotrichum gloeosporioides
5. Aspergillus flavus
