Provedor de dados: 86
Autores: Cardozo Junior,Euclides Lara; Donaduzzi,Carmen Maria; Ferrarese-Filho,Osvaldo; Friedrich,Juliana Cristhina; Gonela,Adriana; Sturion,José Alfredo.
The objective of this work was to determine the contents of methylxanthines, caffeine and theobromine, and phenolic compounds, chlorogenic and caffeic acids, in 51 mate progenies (half-sib families) and estimate the heritability of genetic parameters. Mate progenies were from five Brazilian municipalities: Pinhão, Ivaí, Barão de Cotegipe, Quedas do Iguaçu, and Cascavel. The progenies were grown in the Ivaí locality. The contents of the compounds were obtained by high performance liquid chromatography (HPLC). The estimation of genetic parameters by the restricted maximum likelihood (REML) and the prediction of genotypic values via best linear unbiased prediction (BLUP) were obtained by the Selegen - REML/BLUP software. Caffeine (0.248-1.663%) and...

High temperatures on root growth and lignification of transgenic glyphosate-resistant soybean
Provedor de dados: 115
Autores: Zonetti,P. da Costa; Suzuki,L. Sayuri; Bonini,E. Aparecida; Ferrarese,M. L. Lucio; Ferrarese-Filho,Osvaldo.
Glyphosate resistant transgenic soybean [Glycine max (L.) Mettill] expresses a glyphosate insensitive EPSPS (5-enolpyruvylshikimate-3-phosphate synthase). This enzyme is involved in important secondary metabolism pathways, including lignin biosynthesis. Thus, differences in lignin content and growth between susceptible (OC14) and glyphosate-resistant soybean may be observed. The objective of this study was to evaluate differences between growth and lignin content of roots in transgenic and OC14 soybean cultivated at high temperatures. Seeds from the OC14 soybean and its transgenic cultivar, CD213RR, were germinated at 25, 27.5, 30 and 32.5 °C. After 3 d, seedlings were cultivated in Hoagland half-strength nutrient solution during 12 h photoperiods and at...

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.

Peroxidase and lipid peroxidation of soybean roots in response to p-coumaric and p-hydroxybenzoic acids
Provedor de dados: 52
Autores: Doblinski,Patrícia Minatovicz F.; Ferrarese,Maria de Lourdes L.; Huber,Domitila A.; Scapim,Carlos Alberto; Braccini,Alessandro de Lucca e; Ferrarese-Filho,Osvaldo.
The scope of the present study was to investigate how the p-coumaric (p-CA) and p-hydroxybenzoic (p-HD) acids affect the peroxidase (POD, EC 1.11.1.7) activity, the lipid peroxidation (LP) and the root growth of soybean (Glycine max (L.) Merr.). Three-day-old seedlings were cultivated in nutrient solution containing p-CA or p-HD (0.1 to 1 mM) for 48 h. After uptake, both compounds (at 0.5 and 1 mM) decreased root length (RL), fresh weight (FW) and dry weight (DW) while increased soluble POD activity, cell wall (CW)-bound POD activity (with 1 mM p-CA and 0.5 mM p-HD) and LP.

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.

Naringenin inhibits the growth and stimulates the lignification of soybean root
Provedor de dados: 52
Autores: Bido,Graciene de Souza; Ferrarese,Maria de Lourdes Lucio; Marchiosi,Rogério; Ferrarese-Filho,Osvaldo.
The flavanone naringenin, an intermediate in flavonoid biosynthesis, was tested for its effect on root growth, phenylalanine ammonia-lyase (PAL) and peroxidase (POD) activities, as well as phenolic compounds and lignin contents in soybean (Glycine max L. Merrill) seedlings. Three-day-old seedlings were cultivated in half-strength Hoagland nutrient solution (pH 6.0), with or without 0.1 to 0.4 mM naringenin in a growth chamber (25°C, 12-h photoperiod, irradiance of 280 µmol m-2 s-1) for 24 h. Inhibitory effects on root growth (length, weight, cell viability), PAL and soluble POD activities were detected after naringenin treatments. These effects were associated with stimulatory activity of the cell wall-bound POD followed by an increase in the lignin...
