Flowers and mycorrhizal roots – closer than we think?

Nouri, Eva ; Reinhardt, Didier

In: Trends in Plant Science, 2015, vol. 20, no. 6, p. 344–350

Roots and flowers are formed at the extreme ends of plants and they differ in almost every aspect of their development and function; even so, they exhibit surprising molecular commonalities. For example, the calcium and calmodulin-dependent protein kinase (CCaMK) plays a central role in root symbioses with fungi and bacteria, but is also highly expressed in developing anthers. Moreover,...

The role of the cell wall compartment in mutualistic symbioses of plants

Rich, Mélanie K. ; Schorderet, Martine ; Reinhardt, Didier

In: Plant-Microbe Interaction, 2014, vol. 5, p. 238

Plants engage in mutualistic interactions with microbes that improve their mineral nutrient supply. The most wide-spread symbiotic association is arbuscular mycorrhiza (AM), in which fungi of the order Glomeromycota invade roots and colonize the cellular lumen of cortical cells. The establishment of this interaction requires a dedicated molecular-genetic program and a cellular machinery of the...

The PAM1 gene of petunia, required for intracellular accommodation and morphogenesis of arbuscular mycorrhizal fungi, encodes a homologue of VAPYRIN

Feddermann, Nadja ; Duvvuru Muni, Rajasekhara Reddy ; Zeier, Tatyana ; Stuurman, Jeroen ; Ercolin, Flavia ; Schorderet, Martine ; Reinhardt, Didier

In: The Plant Journal, 2011, vol. 64, no. 3, p. 470–481

Most terrestrial plants engage into arbuscular mycorrhizal (AM) symbiosis with fungi of the phylum Glomeromycota. The initial recognition of the fungal symbiont results in the activation of a symbiosis signalling pathway that is shared with the root nodule symbiosis (common SYM pathway). The subsequent intracellular accommodation of the fungus, and the elaboration of its characteristic feeding...

Phosphate systemically inhibits development of arbuscular mycorrhiza in Petunia hybrida and represses genes involved in mycorrhizal functioning

Breuillin, Florence ; Schramm, Jonathan ; Hajirezaei, Mohammad ; Ahkami, Amir ; Favre, Patrick ; Druege, Uwe ; Hause, Bettina ; Bucher, Marcel ; Kretzschmar, Tobias ; Bossolini, Eligio ; Kuhlemeier, Cris ; Martinoia, Enrico ; Franken, Philipp ; Scholz, Uwe ; Reinhardt, Didier

In: The Plant Journal, 2010, p. -

Most terrestrial plants form arbuscular mycorrhiza (AM), mutualistic associations with soil fungi of the order Glomeromycota. The obligate biotrophic fungi trade mineral nutrients, mainly phosphate (Pi), for carbohydrates from the plants. Under conditions of high exogenous phosphate supply, when the plant can meet its own P requirements without the fungus, AM are suppressed,...
