“…In the present study, we confirmed that MIR is functional in citrus defense against adapted lines of T. urticae grown for several generations on lemon as a neutral host. Unlike several studies indicating that mite performance is improved in mycorrhized plants such as common bean (Hoffmann and Schausberger, 2012;Patiño-Ruiz and Schausberger, 2014), C. aurantium plants displayed reduced damaged leaf surface and oviposition after three days of herbivory. Notably, C. aurantium has a strong basal level of resistance against this mite compared to other citrus genotypes (Bruessow et al, 2010;Agut et al, 2014).…”

“…Although its role in MIR in citrus remains unclear, it is likely that it mediates enhanced immune responses against the mite. The increase in oxocarboxylic acids, carbon metabolites, and amino acids in both AM and AMinf (24 hpi) plants may suggest a better nutritional status of the host, which contributes to better performance of the mite, as has been shown in other mycorrhized plants (Hoffmann and Schausberger, 2012;Patiño-Ruiz and Schausberger, 2014). However, this was not observed in AM C. aurantium; on the contrary, the pathway ontology classification showed an increased number of hits regarding phenylpropanoids and vitamins, suggesting a metabolic flux from carbon and amino acid precursors into more specialized secondary metabolites.…”

Mycorrhizal Symbiosis Triggers Local Resistance in Citrus Plants Against Spider Mites

Citrus plants are a highly mycotrophic species with high levels of fungal colonization. Citrus aurantium rootstocks typically show abundant root colonization by Rhizophagus irregularis three weeks after inoculation. Mycorrhizal symbiosis protects plants against multiple biotic stressors, however, such protection against spider mites remains controversial. We examined mycorrhiza-induced resistance (MIR) in citrus against the two-spotted spider mite Tetranychus urticae. Mycorrhized C. aurantium displayed reduced levels of damage in leaves and lower mite oviposition rates, compared to non-mycorrhized controls. Mycorrhization did not affect host choice of mites in Y-tube assays; of note, C. aurantium has innate strong antixenotic resistance against this mite. Analysis of metabolism pathways in mycorrhized citrus plants showed upregulated expression of the oxylipin-related genes LOX-2 and PR-3 early after infestation. Accordingly, jasmonic acid (JA), 12-oxo phytodienoic acid (OPDA), and JA-Ile concentrations were increased by mycorrhization. Non-targeted metabolomic analysis revealed the amino acid, oxocarboxylic acid, and phenylpropanoid metabolism as the three major pathways with more hits at 24 h post infection (hpi) in mycorrhized plants. Interestingly, there was a transition to a priming profile of these pathways at 48 hpi following infestation. Three flavonoids (i.e., malic acid, coumaric acid, and diconiferyl alcohol) were among the priming compounds. A mixture containing all these compounds provided efficient protection against the mite. Unexpectedly, systemic resistance did not improve after 72 h of primary infestation, probably due to the innate strong systemic resistance of C. aurantium. This is the first study to show that MIR is functional against T. urticae in locally infested citrus leaves, which is mediated by a complex pool of secondary metabolites and is likely coordinated by priming of JA-dependent responses.

“…The rhizosphere microbial community may consist of a huge diversity of pathogenic, neutral and/or mutualistic micro-organisms. Among the usually mutualistic symbionts, it is especially mycorrhizal fungi, rhizobia and plant growth-promoting rhizobacteria (PGPR) that may influence aboveground plant growth and defense against pathogens and herbivores ( Hoffmann et al, 2009 , 2011a , b ; Hoffmann and Schausberger, 2012 ; Khaitov et al, 2015 ; Pangesti et al, 2015 ; Nunes and Kotanen, 2017 ; Friman et al, 2021b ). Here, we studied plant-mediated interactions between free-living soil bacteria that are commonly considered PGPR and aboveground herbivorous spider mites on strawberry plants.…”

“…Severe spider mite infestations may strongly reduce strawberry fruit quality and quantity ( Attia et al, 2013 ). While the effects of rhizosphere fungi on aboveground-feeding spider mite performance have been investigated in various plants such as bean ( Hoffmann et al, 2009 , 2011a ; Hoffmann and Schausberger, 2012 ; Patiño-Ruiz and Schausberger, 2014 ), tomato ( Pappas et al, 2018 ), and pepper ( Pappas et al, 2021 ), it is unknown whether the presence of PGPR in the soil influences the defense system of strawberry plants against spider mites. This is an important question because spider mites usually thrive and are favored by high N-contents of plants ( Wermelinger et al, 1985 , 1991 ) such as presumably provided by PGPR ( Khaitov et al, 2015 for common bean Phaseolus vulgaris L.).…”

Plants mediate interactions between below- and above-ground microbial and animal communities. Microbial communities of the rhizosphere commonly include mutualistic symbionts such as mycorrhizal fungi, rhizobia and free-living plant growth-promoting rhizobacteria (PGPR) that may influence plant growth and/or its defense system against aboveground pathogens and herbivores. Here, we scrutinized the effects of three PGPR, Azotobacter chroococcum, Azospirillum brasilense, and Pseudomonas brassicacearum, on life history and population dynamics of two-spotted spider mites, Tetranychus urticae, feeding on aboveground tissue of strawberry plants, and examined associated plant growth and physiology parameters. Our experiments suggest that these three species of free-living rhizobacteria strengthen the constitutive, and/or induce the direct, anti-herbivore defense system of strawberry plants. All three bacterial species exerted adverse effects on life history and population dynamics of T. urticae and positive effects on flowering and physiology of whole strawberry plants. Spider mites, in each life stage and in total, needed longer time to develop on PGPR-treated plants and had lower immature survival rates than those fed on chemically fertilized and untreated plants. Reduced age-specific fecundity, longer developmental time and lower age-specific survival rates of mites feeding on rhizobacteria treated plants reduced their intrinsic rate of increase as compared to mites feeding on chemically fertilized and control plants. The mean abundance was lower in spider mite populations feeding on PGPR-treated strawberries than in those feeding on chemically fertilized and untreated plants. We argue that the three studied PGPR systemically strengthened and/or induced resistance in above-ground plant parts and enhanced the level of biochemical anti-herbivore defense. This was probably achieved by inducing or upregulating the production of secondary plant metabolites, such as phenolics, flavonoids and anthocyanins, which were previously shown to be involved in induced systemic resistance of strawberry plants. Overall, our study emphasizes that PGPR treatment can be a favorable strawberry plant cultivation measure because providing essential nutrients needed for proper plant growth and at the same time decreasing the life history performance and population growth of the notorious herbivorous pest T. urticae.

“…Although we know much about interactions of plant-symbiotic fungi with insects (e.g. Rowan et al 1990 ; Breen 1994 ; Elliot et al 2000 ; Clay and Schardl 2002 ; Potter et al 2008 ; García Parisi et al 2014 ), effects of these symbionts on mite herbivores have largely focused on interactions between root-associated microorganisms and the cosmopolitan pest, T. urticae (reviewed by Hoffmann and Schausberger 2012 ). For example, Zhang et al ( 2012 ) demonstrated that the endophyte Neotyphodium gansuense Li & Nan, which is associated with drunken horse grass, Achnatherum inebrians (Hance) Keng, reduced both feeding and survival of the spider mite Tetranychus urticae Koch.…”

Phytophagous mites and endophytic fungi may interact when sharing a host plant, potentially influencing one another’s growth or population dynamics; however, interactions between them are poorly known and remain largely unexplored. In this study, quantitative associations between three species of phytophagous mites and the endophytic fungus Epichloë bromicola Leuchtm. & Schardl (Clavicipitaceae, Ascomycotina) on quackgrass, Elymus repens (L.) Gould are reported. The mites’ abundance was assessed on field-collected grass shoots that were either exhibiting choke disease symptoms or without the fungus. Overall, the abundance of Tetranychus urticae and Aculodes mckenziei was significantly lower on quackgrass plants infected by E. bromicola compared to plants without the fungus. Conversely, populations of Abacarus hystrix were significantly larger on plants colonised by the fungus than on uninfected plants. Thus, the presence of this endophytic fungus may have divergent effects on different phytophagous mite species although the basis of these effects is not yet known.
