TLDR
Synthetic lines of Brassica napus were derived by combining the genomes of B. atlantica and B. oleracea var.Abstract:
Synthetic lines of Brassica napus were derived by combining the genomes of B. atlantica and B. oleracea var. alboglabra, which were respectively resistant and susceptible to foliar infection by Leptosphaeria maculans, with a susceptible line of B. rapa. Resistance was expressed in the synthetic lines containing the genome of B. atlantica. The high levels of alkenyl glucosinolates which occur in leaves of B. atlantica, and which have been implicated in disease resistance, were also expressed within the synthetic lines, although the dominant glucosinolate had changed from sinigrin to glucobrassicanapin. Disease resistance and glucosinolate profiles did not co-segregate in F2 progeny from crosses between the synthetic lines.read more

Preformed Antimicrobial Compounds and Plant Defense against Fungal Attack.
TL;DR: A complementary approach involving the study of fungal mechanisms of resistance to preformed inhibitors, and of the contribution of this resistance to fungal pathogenicity to the relevant host plants, offers another route toward investigating the importance of these inhibitors in plant defense.

Myrosinase: gene family evolution and herbivore defense in Brassicaceae.
TL;DR: The evolution of the glucosinolate-myrosinase system and its impact on the interaction between plants and insects are discussed, and data suggesting additional functions in the defense against pathogens and in sulfur metabolism are reviewed.

Role of secondary metabolites in defense mechanisms of plants
TL;DR: This review presents an overview about some of the mechanisms by which plants protect themselves against herbivory, pathogenic microbes and various abiotic stresses as well as specific plant responses to pathogen attack, the genetic control of host-pathogen interactions.

TL;DR: It is suggested that glucosinolate-derived antimicrobial ITCs can play a role in the protection of Arabidopsis against particular pathogens.

A systemic pathway in the infection of oilseed rape plants by Leptosphaeria maculans
TL;DR: In growth room regimes arranged to simulate field conditions which coincide with natural infection of oilseed rape by Leptosphaeria maculans, leaf inoculation resulted in systemic infection, eventually invading and killing cells of the stem cortex and causing the stem canker symptom.

Variation in the glucosinolate content of oilseed rape (Brassica napus L.) leaves. II. Response to infection by Alternaria brassicae (Berk.) Sacc.
TL;DR: In this article, the authors investigated the changes in glucosinolate concentration in leaves of oilseed rape following inoculation with the dark leaf spot pathogen (Alternaria brassicae).
Journal ArticleDOI
In vitro activity of glucosinolates and their products against Leptosphaeria maculans
TL;DR: Levels of glucosinolates reported to occur in leaves of oilseed rape correspond with levels shown here to be sufficient to generate strongly antifungal hydrolysis products, and the significance of these compounds in resistance to L. maculans is discussed.
