Constitutive elevated accumulation of phenylpropanoids in soybean roots at low temperature.

Popis výsledku v původním jazyce

Changes in phenolic acid and isoflavonoid contents in soybean (Glycine max. (L.) Merr) roots after 24-h of low temperature cultivation were investigated. The level of total phenolic acids (represented by the sum of derivatives of benzoic and cinnamic acids) and genistein, daidzein and genistin (glucosyl conjugate of genistein) increased after 24 h of exposure to low temperature. In chill-treated roots the highest increase in genistin was observed. Application of 2-aminoindan-2-phenylphoshonic acid (AIP), a competitive inhibitor of L-phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) resulted in an increased level of endogenous free phenylalanine. An increase in the content of free phenylalanine is regarded as an indication for the inhibition of PAL in vivo.Chilling with AIP decreased valine level. AIP applied in combination with chilling decreased phenolic acids but did not effect the isoflavonoids content. These findings may indicate that the increase in the phenolics level conies from th
