Metabolite Variation between Nematode and Bacterial Seed Galls in Comparison to Healthy Seeds of Ryegrass Using Direct Immersion Solid-Phase Microextraction (DI-SPME) Coupled with GC-MS

Molecules, 2023
Annual ryegrass toxicity (ARGT) is an often-fatal poisoning of livestock that consume annual ryegrass infected by the bacterium Rathayibacter toxicus. This bacterium is carried into the ryegrass by a nematode, Anguina funesta, and produces toxins within ...

Phytohormones in Japanese Mugwort Gall Induction by a Gall-Inducing Gall Midge [PDF]

Bioscience, Biotechnology, and Biochemistry, 2013
A variety of insect species induce galls on host plants. Liquid chromatographic/tandem mass spectrometric analyses showed that a gall midge (Rhopalomyia yomogicola) that induces galls on Artemisia princeps contained high levels of indole-3-acetic acid and cytokinins. The gall midge larvae also synthesized indole-3-acetic acid from tryptophan.

Spatial distribution of Cynips quercusfolii (Hymenoptera: Cynipidae) galls on leaves and within the crowns of oak trees

European Journal of Entomology, 2013
The factors that affect oviposition and consequently spatial distribution of the galls of many gall makers are poorly understood. Knowledge of these factors could result in a better understanding of the mechanisms that initiate and regulate the ...

Phenolic substances and cyanogenesis in galled and non-galled tissue of the fern species Microgramma vacciniifolia

Brazilian Journal of Biology, 2021
Galls, neo-formed plant structures that can occur in different organs, are generated by species-specific interaction with an inducing organism. Inducers manipulate the metabolism of its host. Microgramma vacciniifolia (Langsd. & Fisch.) Copel.

BIOCHEMICAL ALTERATIONS IN Ulmus pumila L. LEAVES INDUCED BY GALLING APHID Tetraneura ulmi L.

Acta Scientiarum Polonorum: Hortorum Cultus, 2018
It is commonly believed that gall inducers have the ability to control and program the host plant growth to their own benefit. The pattern of changes in the contents of reducing sugars, protein and phenolic compounds as well as the activity of chitinase
