Adaptive phenotypic plasticity in chemical defense is thought to play a major role in plant-herbivore interactions. We investigated genetic variation for inducibility of defensive traits in wild radish plants and asked if the evolution of induction i

Control of messenger RNA (mRNA) stability serves as an important mechanism for regulating gene expression. Analysis of Arabidopsis mutants that overaccumulate soluble methionine (Met) revealed that the gene for cystathionine γ-synthase (CGS), the ke

Summary The glucosinolate content of leaves, stems and roots of a range of Chinese oilseed rape (Brassica napus L.) breeding lines was analysed. Total content and spectrum of individual glucosinolates varied widely, and there was no correlation betwe

L-Homophenylalanine (L-HPhe) is the precursor of 2-phenylethylglucosinolate, a secondary metabolite present in some Brassica and related species. A key step in its biosynthesis is the oxidative decarboxylation of L-HPhe to its aldoxime. The enzyme ca

Benzylglucosinolate was detected in all of the tissues of Carica papaya (pawpaw). No other glucosinolates were detected in any tissue of C. papaya . Previous suggestions that indolyl-3-methylglucosinolate might be present could not be confirmed. The

The initial steps in glucosinolate biosynthesis are thought to proceed from amino acids, via N-hydroxy amino acids, to aldoximes. We showed previously that microsomes from green leaves of oilseed rape (Brassica napus cv Bienvenu) contain two distinct

Many secondary metabolites found in plants have a role in defence against herbivores, pests and pathogens. In this review, a few examples are described and discussed, and some of the problems in determining the precise role(s) of such metabolites hig

Ammonia assimilation in chloroplasts occurs via the glutamine synthetase/glutamate synthase (GS/GOGAT) cycle. To determine the extent to which these enzymes contribute to the control of ammonia assimilation, a metabolic control analysis was performed

Applying a salicylic acid soil drench to oilseed rape plants increased the concentration of glucosinolates in their leaves. The intensity of this «induction» depended on the concentration of salicylic acid applied and the age of the leaf: developin
