Antioxidant metabolism in galls due to the extended phenotypes of the associated organisms

Animal-induced galls are considered extended phenotypes of their inducers, and therefore plant morphogenesis and metabolism may vary according to the species of gall inducers. The alterations in vacuolar and apoplastic polyphenols, carotenoids, chlorophyll fluorescence rates, PSII quantum yield, and phospholipid peroxidation were studied in galls induced by Ditylenchus gallaeformans (Nematoda) on Miconia albicans and M. ibaguensis (Melastomataceae), and by an unidentified Eriophyidae (Acarina) on M. ibaguensis. The focus currently addressed is gall metabolism as the extended phenotype of the gall inducers, and the neglected determination of gall functionalities over host plant peculiarities. Galls induced by D. gallaeformans on M. albicans and by the Eriophyidae on M. ibaguensis have increased accumulation of apoplastic and vacuolar phenolics, which is related to the control of phospholipid peroxidation and photoprotection. The galls induced by D. gallaeformans on M. ibaguensis have higher carotenoid and vacuolar polyphenol contents, which are related to excessive sunlight energy dissipation as heat, and photoprotection. Accordingly, antioxidant strategies varied according to the gall-inducing species and to the host plant species. The distinctive investments in carotenoid and/or in polyphenol concentrations in the studied galls seemed to be peculiar mechanisms to maintain oxidative homeostasis. These mechanisms were determined both by the stimuli of the gall-inducing organism and by the intrinsic physiological features of the host plant species. Therefore, the roles of both associated organisms in host plant-galling organisms systems over gall metabolism is attested.

“…The remaining four-oviposition, galling, seed predation, and wood boring-are endophytic, wherein the insect body, in most cases a nymph or a larva, occurs within the tissue being consumed (Coulson and Witter 1984). Fungal damage (Sinclair et al 1987), frequently difficult to characterize, can occur on leaf surfaces, as epiphyllous fungi, or within leaf tissues (Labandeira and Prevec 2014), typically associated with infection of preexisting insect damage such as galls (Constantino et al 2009 figure 7 includes herbivory on the four seed plants, a mixoneuroid odontopteroid, a possible Rhachiphyllum sp., Sandrewia texana, and Walchia piniformis; figures 8-12 consist of herbivory on Auritifolia waggoneri; figure 13 illustrates a variety of seed predation; figure 14 documents the herbivore community structure on the two most herbivorized plants, A. waggoneri (top) and Taeniopteris sp.…”

“…Th e various aspects of FA in plants have been studied in diff erent environments, such as coastal areas, estuaries, tropical dry forests, rain forests, neotropical savannas, and rupicolous habitats (Torrez-Terzo & Pagliosa 2007;Constantino et al 2009;Graham et al 2010;De Sibio & Rossi 2012). Most such studies have shown that plant asymmetry is greater in disturbed areas.…”

Fluctuating asymmetry of and herbivory on Poincianella pyramidalis (Tul.) L.P. Queiroz (Fabaceae) in pasture and secondary tropical dry forest

et al. 2013

Plants subjected to stressful environments tend to be more asymmetric with reduced defenses and are therefore more vulnerable to herbivory. Th is study investigates the relationship between herbivory and fl uctuating asymmetry (FA) in Poincianella pyramidalis in two contrasting habitat types in the Brazilian caatinga (shrublands). We tested the following hypotheses: that FA occurs in P. pyramidalis; that FA of P. pyramidalis leaves is greater in individuals located in pasture than in those located in secondary tropical dry forest; that herbivory by insects (leaf chewers and leaf miners) increases in parallel with increases in the level of FA; and that herbivory is more common in pasture than in secondary tropical dry forest. In each of the two environments, we sampled 20 plants and evaluated 400 leafl ets. We submitted FA data to the Shapiro-Wilk test of normality, and we investigated the other variables using generalized linear models. We found that FA was present in all P. pyramidalis individuals evaluated but was greater in those located in the more degraded habitat (pasture). In addition, although herbivory was similar between the two habitats, there was positive relationship between FA and herbivory. Th is indicates that herbivores select plants that are more asymmetric, regardless of the type of habitat involved, which might be attributable to the mechanisms posited in the plant stress hypothesis.
