RELATIONSHIPS BETWEEN MYCORRHIZAE AND ROOT HAIRS

Popis výsledku v původním jazyce

Mycorrhizal extraradical hyphae and root hairs coexist on the root surface and are responsible for water and nutrient absorption from the soil. Root hairs generally are a preferential adhesion point colonized by ectomycorrhizal hyphae, and eventually are suppressed or incorporated in the fungal mantle. However, arbuscular mycorrhizal (AM) fungi occasionally penetrate root hairs of host plants. A root hair feature is not a reliable indicator of mycorrhizal dependency in plants, as well a mycorrhizal growth response. AM fungal inoculation has increased and reduced effects on root-hair growth (including length, density, and diameter), which is related mainly with auxin and some potential factors (i.e. P and glucose). Such AM effects on root hair can be regulated by substrate P and soil water levels. Root hairs have the preponderant role in soil adhesion under sand or semi-arid conditions, in comparison with extraradical hyphae. In addition, root hairs have higher effectiveness in P acquisition and utilization in biomass production than extraradical hyphae under P-deficient conditions. Under drought stress, AM fungi almost replace the absence of root hairs to enhance plant tolerance through alternative pathways.
