To better understand the evolution of the enzyme phosphoenolpyruvate carboxylase (PEPC) and to test its versatility as a molecular character in phylogenetic and taxonomic studies, we have characterized and compared 70 new partial PEPC nucleotide and amino acid sequences (about 1100 bp of the 3' side of the gene) from 50 plant species (24 species of Bryophyta, 1 of Pteridophyta, and 25 of Sperma...

It is known that plant-based ethnomedicine represented the foundation of modern pharmacology and that many pharmaceuticals are derived from compounds occurring in plant extracts. This track still stimulates a worldwide investigational activity aimed at identifying novel bioactive products of plant origin. However, the discovery that endophytic fungi are able to produce many plant-derived drugs ...

Differentiated plants and suspension cultures of the taxonomic divisions Bryophyta, Pteridophyta, and Spermatophyta have been investigated as to their ability to detoxify heavy metals like Cd2+ through the formation o f (y-Glu —Cys)„—Giy peptides, the phytochelatins. Over 200 individual plants have been checked and there was not a single exception observed. Only in the order Fabales several spe...
