THE MYROSINASE-GLUCOSINOLATE SYSTEM, ITS ORGANISATION AND BIOCHEMISTRY
TLDR
The compartmentalization of the components of the myrosinase-glucosinolate system and the cell-specific expression of theMyrosinases represents a unique plant defence system. Expand
The enzymic and chemically induced decomposition of glucosinolates.
TLDR
Early empirical work on glucosinolate degradation along with more recent aspects related to current research on mechanism of glucosInolate degradation in plants, microbes and animals are highlighted. Expand
Towards global understanding of plant defence against aphids--timing and dynamics of early Arabidopsis defence responses to cabbage aphid (Brevicoryne brassicae) attack.
TLDR
A time series-based investigation of Arabidopsis thaliana subjected to attack by a specialist pest of Brassicaceae species, Brevicoryne brassicae, revealed the initiation of extensive gene expression changes already during the first 6 h of infestation. Expand
The ‘mustard oil bomb’: not so easy to assemble?! Localization, expression and distribution of the components of the myrosinase enzyme system
TLDR
In this review, data from the model plant Arabidopsis thaliana is compared to that from other glucosinolate-producing Brassicaceae in order to show common as well as divergent features of the ‘mustard oil bomb’ among these species. Expand
Transcriptional responses of Arabidopsis thaliana ecotypes with different glucosinolate profiles after attack by polyphagous Myzus persicae and oligophagous Brevicoryne brassicae.
TLDR
The induction of the jasmonic acid synthesis pathway was strongest in Cvi, while the up-regulation of the indole glucosinolate synthesis pathways was highest in Ler, suggesting a slightly different defence strategy in these two ecotypes. Expand
Domestic processing of onion bulbs (Allium cepa) and asparagus spears (Asparagus officinalis): effect on flavonol content and antioxidant status.
TLDR
Two commonly consumed plant foods, onion bulbs and asparagus spears, were subjected to typical domestic processing, including chopping, maceration, and boiling, and the consequences of these processes on the antioxidant capacity of the tissues were evaluated with the beta-carotene bleaching method. Expand
The cabbage aphid: a walking mustard oil bomb
TLDR
It is demonstrated that aphid myrosinase expression in head/thoracic muscle starts during embryonic development and protein levels continue to accumulate after the nymphs are born, indicating the apparent lack of an effective chemical defence system in adult winged aphids. Expand
Spatial organization of the glucosinolate–myrosinase system in brassica specialist aphids is similar to that of the host plant
TLDR
It is proposed that death, or damage, to the insect by predators or disease causes disruption of compartmentalized myrosinase, which results in the release of isothiocyanate that acts as a synergist for the alarm pheromone E–β–farnesene. Expand
Characterisation of recombinant epithiospecifier protein and its over-expression in Arabidopsis thaliana.
TLDR
In vitro assays with a recombinant ESP showed that the formation of epithionitriles from alkenylglucosinolates is ESP and ferrous ion dependent and Nitrile formation in vitro however does not require ESP but only the presence of Fe(II) and myrosinase. Expand
Accumulation of Glucosinolates by the Cabbage Aphid Brevicoryne brassicae as a Defense Against Two Coccinellid Species
TLDR
The results indicate that the presence of sinigrin in the diet of B. brassicae makes this aphid unsuitable as a food source for A. bipunctata but not for C. septempunctata, although for this ladybird species, there appear to be costs associated with feeding on aphids that contain this secondary metabolite.
