48. Consider the following statement about Mycorrhizal fungi.
1. They form a network of fine filaments associate with plant roots to draw nutrients and water from the soil.
2. Ectomycorrhizal fungi develop exclusively on the exterior of root cells.
3. Mycorrhizal fungi increase plant tolerance to different environmental stresses.
4. It decreases plant tolerance to soil salinity.
Which of the above statement(s) is/are correct?

The correct option is A Only 1, 2 and 3
Mycorrhizal fungi colonize the plant’s root system and develop a symbiotic association called “mycorrhiza”
They form a network of fine filaments that associate with plant roots and draw nutrients and water from the soil that the root system would not be able to access otherwise. Mycorrhizae are formed with more than 90% of plant species.
There are two major groups of mycorrhizal fungi: ectomycorrhizal and endomycorrhizal fungi.
Members of the former group develop exclusively on the exterior of root cells, whereas those of the latter penetrate the plant cells where direct metabolic exchanges can occur. Mycorrhizal fungi allow plants to draw more nutrients and water from the soil. They also increase plant tolerance to different environmental stresses. Moreover, these fungi play a major role in soil aggregation process and stimulate microbial activity. According to the plant species and to the growing practices and conditions, mycorrhizae provide different benefits to the plants and to the environment:
1. Increase tolerance to soil salinity
2. Reduce disease occurrence
3. Contribute to maintain soil quality and nutrient cycling
4. Contribute to control soil erosion.
