Soft rot (type II) fungi belonging to the family Xylariaceae are known to substantially degrade hardwood by means of their poorly understood lignocellulolytic system, which comprises various hydrolases, including feruloyl esterases and laccase. In the present study, several members of the Xylariaceae were found to exhibit high feruloyl esterase activity during growth on lignocellulosic material...

Lignin biosynthesis in excised tissues of Sorghum vulgare variety Wheatland milo incubated in air with and without prior infiltration with H(2)O was presumably limited by H(2)O(2) production and was dependent upon an endogenous substrate, probably starch. In solution culture without shaking, this conversion of endogenous material was partially blocked at some step prior to p-hydroxycinnamic aci...

The pattern of change in the endogenous levels of several plant hormones and hydroxycinnamic acids in addition to growth and photosynthetic performance was investigated in banana plants (Musa acuminata cv. "Grand Nain") subjected to various cycles of drought. Water stress was imposed by withholding irrigation for six periods with subsequent rehydration. Data showed an increase in abscisic acid ...

Previously, we reported that MALDI spectra of peptides became reproducible when temperature was kept constant. Linear calibration curves derived from such spectral data could be used for quantification. Homogeneity of samples was one of the requirements. Among the three popular matrices used in peptide MALDI [i.e., α-cyano-4-hydroxycinnamic acid (CHCA), 2,5-dihydroxybenzoic acid (DHB), and sina...

Tulipa, Liliaceae, Hydroxycinnamic Acid Conjugates, Ferulic Acid Esters, Sucrose Two ferulic acid conjugates have been isolated from the extract of immature anthers of Tulipa cv. “Apeldoorn” and their structures elucidated using chromatography, electron impact mass spectrometry, and NMR spectroscopy. These two conjugates are 6,3'-diferuloylsucrose and 6,3',4'triferuloylsucrose. High performance...
