Some strains establish robust and long-lasting colonization of roots by entering into the first epidermal layers.
Root colonization frequently results in enhancing of growth and development, crop productivity or induction of resistance to abiotic and biotic factors.
The association (interaction) microorganism/plant represents, especially for the first ones, an optimal system to satisfy its needs in terms of nutrition, water, protection to adverse environmental factors (water stress, radiation, extreme temperatures) and to competitors. Plants, therefore, represent a valuable habitat for many heterotrophic organisms and a source of nutrients.
