Comprehensive transcriptome analysis unravels the existence of crucial genes regulating primary metabolism during adventitious root formation in Petunia hybrida

To identify specific genes determining the initiation and formation of adventitious roots (AR), a microarray-based transcriptome analysis in the stem base of the cuttings of Petunia hybrida (line W115) was conducted. A microarray carrying 24,816 unique, non-redundant annotated sequences was hybridized to probes derived from different stages of AR formation. After exclusion of wound-responsive and...

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,...
