Stimulation of hyphal growth of the VA mycorrhizal fungus Gigaspora margarita by suspension‐cultured Pueraria phaseoloides cells and cell products

Abstract: SUMMARYThe efFects of suspension-cultured Pueraria phaseoloides Benth. (pueraria) cells and cell products on growth of hyphae of the VA mycorrhizal fungus Gigaspora margarita Becker & Hall in liquid media were examined. Addition of 6-d-old cell cultures of pueraria cells at a concentration of 25 cells ml"^ of medium caused a 3-9-fold increase in hyphal growth. Higher cell concentrations resulted in less growth stimulation. Cell exudates or extracts (cell products) at a concentration of 25 [A rs\V^ of medium al… Show more

“…This demonstrates the effectiveness of formononetin in cropping systems, ensuring the stimulating effect of native AMF providing more than 20% increase in mycorrhizal colonization, regardless of the other factors studied, several studies in greenhouse related the same with this plant (BAPTISTA; SIQUEIRA, 1994;PAULA;SIQUEIRA, 1990;SILVA-JUNIOR;SIQUEIRA, 1997).…”

“…A germinação dos esporos dos FMAs no solo não necessita de um sinal vegetal para ter início, uma vez que pode ocorrer em água (Paula & Siqueira, 1990;Harrison, 2005). Contudo, a presença de exsudatos de raízes ou de compostos voláteis, como o CO 2 , pode estimular a germinação dos esporos e o crescimento do tubo germinativo, indicando que os FMAs são sensíveis aos compostos presentes na rizosfera (Bécard & Piché, 1989;Gianinazzi-Pearson et al, 1989;Nair et al, 1991).…”

“…3) do que G. clarum. Sabe-se que esporos de G. margarita germinam entre dois a quatro dias e produzem grande quantidade de micélio (Paula & Siqueira 1990), enquanto os esporos de G. clarum levam mais tempo para germinar (De-Souza & Berbara 1999) e produzem menor quantidade de micélio (Paula et ai. 1994).…”
