Variation in herbivore defense strategies among plant species differing in elevational distribution and the role of temperature in defense

open access: yesNew Phytologist, Volume 249, Issue 6, Page 3091-3103, March 2026.
Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.

Sulphoraphane Affinity-Based Chromatography for the Purification of Myrosinase from Lepidium sativum Seeds

open access: yesBiomolecules, 2022
Sulforaphane and other natural isothiocyanates released from the respective plant glucosinolates by the plant enzyme myrosinase (β-thioglucoside glucohydrolase) show extensive anticancer and antimicrobial effects.

Glucosinolate types and concentrations in seedlings of different Brassica species used for food [PDF]

open access: yes, 2005
Brassicaceous food crops contain in their tissues different quantities of the glucoside allelochemicals known as glucosinolates (Bellostas et al., 2004; Sørensen, 1990).

Studies on the Myrosinase fromWasabia japonica:Purification and Some Properties of Wasabi Myrosinase

open access: yesAgricultural and Biological Chemistry, 1979
The myrosinase from Wasabi (Wasabia japonica) is effectively extracted by sonication. The enzyme is purified about 100-fold by gel-filtration on Sephacryl S-200, Sepharose 6B and ion-exchange chromatography on DEAE-Sephadex. The enzyme is active only when L-ascorbic acid is added to the reaction mixture. General reducing reagents (2-mercaptoethanol and

Plant accession and insect infestation, rather than silicon supplementation, shape defence strategies of Arabidopsis halleri towards a leaf beetle

open access: yesPlant Biology, Volume 28, Issue 2, Page 407-419, March 2026.
Chemical and mechanical defences of a metal‐hyperaccumulating plant species Arabidopsis halleri were more influenced by plant accession (genetic background) and insect herbivory by a leaf beetle Phaedon cochleariae than by supplementation of the metalloid silicon.

Aphid parasitism alters induced plant responses allowing a hyperparasitoid to locate its hidden parasitoid host

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2055-2070, February 2026.
Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of

Elucidation of Sulforaphane‐Mediated Effects on the Cellular Human Metabolome Using Metabolic Profiling

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 1, January 2026.
Sulforaphane (SFN) is an isothiocyanate derived from broccoli and is related to various health‐promoting effects. By using metabolic profiling on the hepatoblastoma cell line HepG2 several effects on pathways such as TCA cycle, urea cycle and redox metabolism through SFN were identified.

Processing-bioprocessing of oilseed rape in bioenergy production and value added utilization of remaining seed components [PDF]

open access: yes, 2007
Cruciferous oilseed crops accumulate relatively high concentrations of oil, proteins and dietary fibres (DF) in their seeds, in addition to bioactive components as glucosinolates and myrosinase isoenzymes (thioglucohydrolase; EC 3.2.1.147). When mixed in

Allyl isothiocyanate induced stress response in Caenorhabditis elegans

open access: yesBMC Research Notes, 2011
Background Allyl isothiocyanate (AITC) from mustard is cytotoxic; however the mechanism of its toxicity is unknown. We examined the effects of AITC on heat shock protein (HSP) 70 expression in Caenorhabditis elegans.

SNRK3.15 Is a Crucial Component of the Sulfur Deprivation Response in Arabidopsis thaliana

open access: yesPlant Direct, Volume 10, Issue 1, January 2026.
ABSTRACT Sulfate deprivation (–S) results in numerous metabolic and phenotypic alterations in plants. Kinases are often key players in transducing nutrient status signals to molecular components involved in metabolic and developmental program regulation, but despite the physiological importance of sulfur, to date, no signaling kinases have been ...
