“…After biotic and abiotic stress, LOX activity is increased, and it depends mostly on inducing agents as well as the plant genotype and physiologic conditions (Silva et al 2004). The activation of LOX activity was induced by inoculation in the roots of Rhizophagus irregulars in bean plants ( Phaseolus vulgaris L.) (Mora-Romero et al 2015). At 21 dpi, LOX activity was increased about 50% in P. divaricatum seedlings infected by Fusarium solani f. sp.…”

The aim of this study was to evaluate the changes in the production of secondary metabolites Piper aduncum seedlings were inoculated by spores of the arbuscular mycorrhizal fungi (AMF) Rhizophagus clarus and Claroideoglomus etunicatum. P. aduncum seedlings were inoculated by spores of R. clarus and C. etunicatum and then, development parameters, root colonization, lipoxygenase (LOX) activity, and essential oil (OE) chemical composition were monitored at 30, 60 and 90 days’ post-inoculation (dpi). The inoculation had influenced the plant height and root length at 30 and 90 dpi and microscopic analysis of roots showed the presence of hyphae, arbuscules and vesicles in the inoculated plants. Phenylpropanoids and sesquiterpene hydrocarbons were the main compounds in the EO. In the leaves, the concentration of phenylpropanoids showed a decrease, mainly at 60 dpi, with increased sesquiterpene hydrocarbon production. The main compounds were dillapiole, myristicin, and germacrene D; the dillapiole concentration decreased in all treatments. LOX activity had an increase in the leaves and roots at 90 dpi. These results suggest that alterations in the secondary metabolites of P . aduncum can be induced by its mechanisms of resistance during AMF interaction.

The world demand for phosphate has gradually increased over the last decades, currently achieving alarming levels considering available rock reserves. The use of soil microorganisms, such as arbuscular mycorrhizal fungi (AMF), has been suggested as a promising alternative to improve phosphorus-use efficiency. However, the effect of the source of phosphorus on the interactions within the soil microbial community remains unclear. Here, we evaluated the links between the total dry matter content of sugarcane and the interactions within the soil microbial community under different phosphate sources, with/without AMF inoculation. The phosphate sources were Simple Superphosphate (SS, 18% of P2O5), Catalão rock phosphate (CA, 2.93% of P2O5) and Bayovar rock phosphate (BA, 14% of P2O5). The results indicated that the BA source led to the largest total dry matter content. The phosphate source affected total dry matter and the structure of the soil microbial communities. The bacterial interactions increased across sources with high percentage of P2O5, while the fungal interactions decreased. The interactions between bacterial and fungal microorganisms allowed to identify the percentage of P2O5 resulting in the highest total sugarcane dry matter. Our findings suggested the soil microbial interactions as a potential microbial indicator helping to improve the agricultural management.

“…The different bioprotection effects indicated that MIR was a plant genotype-specific trait. Given that plant species can largely differ in resistance induced by AM fungi against pathogens [ 27 , 59 ], our results suggested that plant genotypes played a pivotal role in plant–AM fungus–pathogen interaction.…”

“…A study on two tomato varieties (Micro-Tom and Missouri) showed that only Missouri benefited from the inoculation with the AM fungus Rizophagus irregularis (DAOM 197198) against Xanthamonas campestris pv. vesicatoria , whereas this protection effect was not observed in Micro-Tom [ 27 ].…”

Arbuscular mycorrhizal (AM) fungi can form mutual symbiotic associations with most terrestrial plants and improve the resistance of host plants against pathogens. However, the bioprotection provided by AM fungi can depend on the host–fungus combinations. In this study, we unraveled the effects of pre-inoculation with AM fungus Rhizophagus irregularis on plant resistance against the hemibiotrophic fungal pathogen Fusarium oxysporum in jasmonate (JA) biosynthesis mutant tomato, suppressor of prosystemin-mediated responses8 (spr8) and the wild type Castlemart (CM). Results showed that R. irregularis colonization in CM plants significantly decreased the disease index, which was not observed in spr8 plants, suggesting that the disease protection of AM fungi was a plant-genotype-specific trait. Inoculation with R. irregularis significantly increased the shoot dry weight of CM plants when infected with F. oxysporum, with increased plant P content and net photosynthetic rate. Induced expression of the JA synthesis genes, including allene oxide cyclase gene (AOC) and lipoxygenase D gene (LOXD), and increased activities of polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL) were recorded in mycorrhizal CM plants infected with F. oxysporum, but not in spr8 plants. Thus, mycorrhiza-induced resistance (MIR) to fungal pathogen in tomato was highly relevant to the JA signaling pathway.
