Plant-insect-fungus association in some plant galls
Proceedings: Animal Sciences, 1984In a number of plant galls caused by members of Diptera, the larval cavity and/or the nutritive zone around it are inhabited by specific fungi. Careful investigations reveal that these fungi are not contaminants, but are brought by the gall insect itself. The fungi appear to lead a mutualistic life not only with the insect larva but also with the plant.

Ecological Genomics of Plant-Insect Interactions: The Case of Wasp-Induced Galls
, 2020 Plant-insect interactions are central to understand ecological and evolutionary dynamics that shaped phenotypes and genotypes. Although the interaction between host plants and insect herbivores has been widely assessed, the molecular mechanisms behind it

The plant WEE1 kinase is involved in checkpoint control activation in nematode‐induced galls [PDF]
New Phytologist, 2020 Galls induced by plant‐parasitic nematodes involve a hyperactivation of the plant mitotic and endocycle machinery for their profit. Dedifferentiation of host root cells includes drastic cellular and molecular readjustments.

Gall forming herbivores induce sinks and act as phloem parasites within their host plants. Their performance on the host plant can depend on the sink-source relationship they establish with the plant. Because sink-source relationships within a plant are reflected in its architecture, we examined how architectural differences among cottonwoods might ...

Gall-Bearing Plants and Gall-Inducing Organisms
1964Galls arise on nearly all the major classes of plants. Although no group of plants is entirely free from galls, even casual observation shows that galls are more common on some groups than among others. Relatively few galls are found, for example, on Cryptogams and Gymnosperms, but the Phanerogams, especially the Dicotyle-donae, are remarkable for the ...

Plant Tolerance of Gall‐Insect Attack and Gall‐Insect Performance
Ecology, 1996We examined plant tolerance of gall—insect attack and gall—insect performance in rosinweed (Silphium integrifolium, Asteraceae) and its apical meristem galler Antistrophus silphii (Hymenoptera: Cynipidae). Gall densities were varied in field rosinweed populations, while gall densities, water, and nutrients were varied for rosinweed in an experimental ...

Crown gall – a plant tumour with biological activities
Phytotherapy Research, 2003AbstractPetroleum ether, acetone, 80% MeOH and water extracts of crown gall, a plant tumour, obtained from Eucalyptus globulus tree were screened for cytotoxic, antioxidant, antiinflammatory, embryotoxic, antitumour‐promoting and antimicrobial activities.In terms of bioactivity the 80% MeOH extract was most effective followed by the acetone extract. The

Gall Midges (Hessian Flies) as Plant Pathogens
Annual Review of Phytopathology, 2012Gall midges constitute an important group of plant-parasitic insects. The Hessian fly (HF; Mayetiola destructor), the most investigated gall midge, was the first insect hypothesized to have a gene-for-gene interaction with its host plant, wheat (Triticum spp.). Recent investigations support that hypothesis. The minute larval mandibles appear to act in
