“…It has been proposed that fatty acids are converted into sugars to feed the growing larva (Martinson et al, 2022). Finally, cynipid galls have previously been shown to contain lower concentrations of chlorophyll and carotenoids (Kot et al, 2018b;Kot et al, 2020), suggesting reduced photosynthesis as an explanation for the reduction in apocarotenoids observed here.…”

Many insects have evolved the ability to manipulate plant growth to generate extraordinary structures called galls in which insect larva can develop while being sheltered within and feeding on the plant. In particular, Cynipid (Hymenoptera: Cynipidae) wasps have evolved to form some of the most morphologically complex galls known and generate an astonishing array of gall shapes, colors, and sizes. However, the biochemical basis underlying these remarkable cellular and developmental transformations remains poorly understood. A key determinant in plant cellular development is the deposition of the cell wall to dictate the physical form and physiological function of newly developing cells, tissues, and organs. However, it is unclear to what degree cell walls are restructured to initiate and support the formation of new gall tissue. Here, we characterize the molecular alterations underlying gall development using a combination of metabolomic, histological, and biochemical techniques to elucidate how leaf cells are reprogrammed to form galls. Strikingly, gall development involves an exceptionally coordinated spatial deposition of lignin and xylan to form de novo gall vasculature. Our results highlight how Cynipid wasps can radically change the metabolite profile and restructure the cell wall to enable the formation of galls, providing new insights into the mechanism of gall induction and the extent to which plants can be entirely reprogrammed to form novel structures and organs.

“…Similar compounds including phenolic acids (cinnamic acid, p-coumaric acid, ferulic acid) and gallotannins (digalloylglucose), found in other plant matrices, demonstrated active roles against oxidative stress and type 2 diabetes [89]. However, the presence of galls on leaves of Q. robur had a negative effect on cell membrane integrity and the antioxidant potential of the host plant [90].…”

Quercus species have been widely used in traditional medicine, and recently, researchers’ attention has focused on galls of the genus Quercus as a source of health-promoting phytochemicals. This review presents a summary of the most recent findings on the phytochemistry and bioactivity of oak galls, following the screening of scientific papers published in two relevant databases, PubMed and Embase, between January 2018 and June 2023. The oak galls are rich in active compounds, mostly gallotannins and phenolic acids. Due to these secondary metabolites, the reviewed studies have demonstrated a wide range of biological activities, including antioxidant and anti-inflammatory actions, antimicrobial properties, tissue-protective effects, and antitumor, anti-aging, and hypoglycemic potential. Thus, oak galls are a promising natural matrix, to be considered in obtaining pharmaceutical and cosmetic preparations used in anti-aging strategies and, together with medications, in the management of age-related diseases. In further evaluations, the valuable functional properties of oak galls, reported mostly in preclinical studies, should be confirmed with clinical studies that would also take into account the potential health risks of their use.

“…In ancient Chinese medical sources, the cynipid galls have been used against many diseases such as cancer (Gao et al, 2018). Many studies have been carried out about the bioactive compounds and biological properties of the galls in especially oriental countries (Asif et al, 2012;Noori et al, 2015;Iylia Arina & Harisun, 2019;Kot et al, 2019;Azmaz et al, 2020;Sukor et al, 2020).…”

The galls of cynipid species (Hymenoptera: Cynipidae) have been used since ancient times as an important source of bioactive compounds. Many researchers have evaluated the medicinal potential of some cynipid galls and found that these galls have numerous ethnomedical uses. The aim of this study was to determine the total bioactive (phenolic, flavonoid and tannin) compound amounts of gall extracts, to reveal the phenolic compound contents by HPLC method and to set ground for future pharmaceutical studies. The galls of cynipid wasps (totally 24 taxa) on host plants were collected from the Eastern Black Sea Region of Türkiye. Acetone, ethanol, methanol, and water extracts of these galls were prepared for quantity analysis and HPLC. The phenolic compound amounts (phenolic, flavonoid and tannin) of the cynipid gall extracts were determined, and their phenolic compound contents were also revealed. Some phenolic compounds in ethanol gall extracts were analyzed using HPLC, and some of these compounds were detected for the first time in the cynipid galls. 2,5-dihydroxybenzoic acid, caffeic acid, epicatechin, and ellagic acid are the most abundant in the ethanolic gall extracts. Total phenolic, flavonoid and tannin amounts of the cynipid gall extracts showed high variation. All these studies on quantification and characterization of phenolic compound are the first detailed studies on these taxa of cynipid galls and show that these cynipid galls might pharmaceutically be an important source for human and animal health.
