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...

In: The Plant Journal, 2008, vol. 54, no. 6, p. 1115 - 1127

The active endogenous dTph1 system of the Petunia hybrida mutator line W138 has been used in several forward-genetic mutant screens that were based on visible phenotypes such as flower morphology and color. In contrast, defective symbiotic phosphate (Pi) transport in mycorrhizal roots of Petunia is a hidden molecular phenotype as the symbiosis between plant roots and fungi takes place...
