Ferulic acid depletion by cultured soybean seedlings under action of glucose and methionine
Provedor de dados: 52
Autores: Herrig,Vanessa; Silva,Hélio Cândido da; Ferrarese,Maria de Lourdes Lucio; Ferrarese-Filho,Osvaldo.
Cultured soybean seedlings were used to investigate how glucose or methionine influenced depletion of ferulic acid. Three-day-old seedlings were grown in hydroponic solution containing ferulic acid plus glucose or methionine, and the level of the phenolic acid were monitored in the nutrient culture. The results showed that ferulic acid depletion was more rapid in the presence of those compounds. After 6 h, the increase caused by glucose (0.01 and 0.05 mM) was more pronounced than methionine in the same concentrations. On the other hand, methionine (0.1 and 0.2 mM) increased depletion more significantly than glucose. Results suggested that both compounds might to increase the allelopathic effects of ferulic acid in the seedlings.

Consumption of ferulic and p-hydroxybenzoic acids by soybean root tips
Provedor de dados: 52
Autores: Silva,Hélio Cândido da; Herrig,Vanessa; Ferrarese,Maria de Lourdes L.; Ferrarese-Filho,Osvaldo.
Depletion method was used to describe how soybean root consumed ferulic and p-hydroxybenzoic acids in nutrient culture. The results showed that excised cultured soybean roots consumed these allelochemicals very rapidly. At concentrations between 0.1 and 1.0 mM, roots consumed 50% or more of ferulic acid after 6-h depletion. Although consumption started only after 3 h, similar behavior was verified with p-hydroxybenzoic acid.
