Abstract/Contents:"Numerous studies have been conducted to determine the positive effects of Neotyphodium endophye-tall fescue symbiosis on plant resistance to different stresses. However, its effects on the uptake of potassium (K) and transformation of K-bearing minerals are not yet known. The objective of this research was to investigate the possible effects of such symbiosis on the transformation of clay-sized micaceous minerals. Tall fescue genotype 75B, both infected and non-infected with natural Neotyphodium endophyte, was cultivated in a mixture of quartz sand and phlogopite or muscovite. Pots were irrigated with distilled water and complete or K-free nutrient solutions for a period of 140 days. K concentrations in shoot and root were determined using a flame photometer and the clay-sized particles in each pot were analyzed using an X-ray diffractometer. Results revealed vermiculitization of phlogopite under both nutrient solutions. In addition to vermiculite, smectite was detected as a newly formed mineral in phlogopite-amended pots. In contrast, a very weak rate of vermiculitization was observed in muscovite-treated media. The rate of phlogopite transformation was significantly higher under the endophyte-infected plants, particularly when the K-free nutrient solution had been applied. Also, the significant decrease in pH value in the rhizosphere of infected plants confirmed the positive effect of endophyte-tall fescue symbiosis on mineral transformation.
