α-Tomatine was not highly phytotoxic and slightly inhibited the stem elongation (7 to 13%) when applied as a spray to etiolated 4-day-old seedlings of sesbania [Sesbania exaltata (Raf.) Rybd.], sicklepod (Senna obtusifolia L.), mungbean (Vigna radiata L.), wheat (Triticum aestivum L.) and sorghum (Sorghum vulgare L.). Tomatidine had less effect on stem elongation than tomatine and reduced the e...

BACKGROUND Gaillardia grandiflora Hort. ex Van Houte and Gaillardia pulchella Foug are flowering plants widely cultivated in Egypt for their ornamental value. Previous reports demonstrated that sesquiterpene derivatives represent the major compounds in both species. Moreover, only few flavones were identified from genus Gaillardia and few studies on the cytotoxicity of G. pulchella were found. ...

Aminomethylphosphonic acid (AMPA) is the most frequently detected metabolite of glyphosate in plants. The objective of this study was to determine if there is any correlation of metabolism of glyphosate to AMPA in different plant species and their natural level of resistance to glyphosate. Greenhouse studies were conducted to determine the glyphosate I 50 values (rate required to cause a 50% re...

Aurone synthase from Coreopsis grandiflora (cgAUS1), catalyzing conversion of butein to sulfuretin in a type-3 copper center, is a rare example of a polyphenol oxidase involved in anabolism. Site-directed mutagenesis around the CuA site of AUS1 was performed, and recombinant enzymes were analyzed by mass spectrometry. Replacement of the coordinating CuA histidines with alanine resulted in the p...

The study was conducted at the On Farm Research Division (OFRD) farm, Rangpur from 2002-2003 to 2004-2005 to see the effect of inorganic fertilizers along with organic manure and mungbean residue on soil properties and yield of crops. For the first crop (maize), there were five treatments. After harvest of maize, mungbean and dhaincha (Sesbania) seeds were sown as per treatments. For T. Aman ri...

Capparis grandiflora was used to treat diarrhoea and other infective disorders in folklore. The present study aims at evaluating the action of chloroform soluble fraction, ethanol soluble fraction and ether soluble fraction of the leaves of Capparis grandiflora against inflammatory diseases. The anti-inflammatory effects were investigated by employing acute inflammatory model i.e.; carrageenan-...
