“…7). Since methionine metabolism is known to be associated with plant defense, 69 it seems there is a link between methionine content and antioxidant molecules in the present research. A similar reaction was observed for isoleucine, which, like methionine, belongs to the aspartate family of amino acids.…”

BackgroundThe present study set out to evaluate the potential of plant growth‐promoting actinobacteria (PGPR) in improving some physiological and molecular parameters of rapeseed (Brassica napus L.) plants under ambient and elevated CO2 conditions by assessing some nitrogen and sulfur‐containing metabolites, antioxidant defense system, and antimicrobial activity. With this aim, a pot experiment was conducted where the rapeseed plants were treated with Actinobacterium sp. strain NCO2 (OQ451136) and were grown under two levels of air CO2 concentrations (ambient CO2 (aCO2, 410 μmol CO2 mol−1; and elevated CO2 (eCO2, 710 μmol CO2 mol−1)).ResultsIncreasing the photosynthetic pigments (+35%‐80%) and photosynthesis rate (+20%‐34%) in PGPB‐treated plants under eCO2 compared to control plants, resulting in further growth and biomass production (+53%‐294%). These results were associated with an enhancement in the content of total antioxidant capacity (+15%‐128%), polyphenols (+21%‐126%), and alpha‐tocopherols (+20%‐138%) under both elevated CO2 and PGPB application (in combination or individual application), while only the combined treatment (eCO2 + PGPB) had a significantly higher accumulation of antioxidant enzymes (+88%‐197%), beta‐tocopherols (+177%), and flavonoids (+155%). Moreover, nitrogen and sulfur‐containing metabolites (glucosinolates and amino acids) were improved by PGPB treatment and/or CO2 levels, in which PGPB increased the amino acid‐derived glucosinolates induction by eCO2 with low levels of effective sulforaphane.ConclusionsTherefore, the interaction effects of beneficial actinobacteria and elevated CO2 are expected to boost the level of such antioxidant molecules and to have a helpful designation in improving plant biomass and adaptability to complicated climate changes in the future.This article is protected by copyright.

“…Methionine (Met), a sulfur‐containing amino acid is necessary for several important physiological and metabolic activities, including the initiation of protein synthesis and methylation of proteins, RNA and DNA (Escaray et al., 2022 ; Saint‐Macary et al., 2015 ; Scott et al., 2020 ; Shrivastava et al., 2021 ). It plays a pivotal role in regulating cell proliferation (Sutter et al., 2013 ; Walvekar et al., 2018 ), autophagy (Sutter et al., 2013 ) and respiration (Tripodi et al., 2018 ) in fungi.…”

“…It has been proposed that fungal pathogens like Magnaporthe oryzae (causal agent of rice blast disease) need to synthesize certain amino acids including methionine, that are present in scarce amounts in the leaf apoplast (Saint-Macary et al, 2015). Methionine (Met), a sulfur-containing amino acid is necessary for several important physiological and metabolic activities, including the initiation of protein synthesis and methylation of proteins, RNA and DNA (Escaray et al, 2022;Saint-Macary et al, 2015;Scott et al, 2020;Shrivastava et al, 2021).

Rhizoctonia solani is a polyphagous necrotrophic fungal pathogen that causes sheath blight disease in rice. It deploys effector molecules as well as carbohydrate‐active enzymes and enhances the production of reactive oxygen species for killing host tissues. Understanding R. solani ability to sustain growth under an oxidative‐stress‐enriched environment is important for developing disease control strategies. Here, we demonstrate that R. solani upregulates methionine biosynthetic genes, including Rs_MET13 during infection in rice, and double‐stranded RNA‐mediated silencing of these genes impairs the pathogen's ability to cause disease. Exogenous treatment with methionine restores the disease‐causing ability of Rs_MET13‐silenced R. solani and facilitates its growth on 10 mM H2O2‐containing minimal‐media. Notably, the Rs_MsrA gene that encodes methionine sulfoxide reductase A, an antioxidant enzyme involved in the repair of oxidative damage of methionine, is upregulated upon H2O2 treatment and also during infection in rice. Rs_MsrA‐silenced R. solani is unable to cause disease, suggesting that it is important for the repair of oxidative damage in methionine during host colonization. We propose that spray‐induced gene silencing of Rs_MsrA and designing of antagonistic molecules that block MsrA activity can be exploited as a drug target for effective control of sheath blight disease in rice.

“…Plant metabolic pathways are complex and highly adaptive to environmental change ( Lindermayr et al 2020 ). Activation of defence genes against pathogens as part of transcriptional reprogramming in systemic acquired resistance involves well-described hormone-signalling networks and secondary metabolites to prevent pathogen propagation ( Bolton 2009 ; Vlot et al 2021 ; Escaray et al 2022 ). Consequently, pathogen response leads to an increased demand for metabolic intermediates ( Bolton 2009 ; Escaray et al 2022 ).…”

Plant environmental memory: implications, mechanisms and opportunities for plant scientists and beyond

Plants are extremely plastic organisms. They continuously receive and integrate environmental information and adjust their growth and development to favor fitness and survival. When this integration of information affects subsequent life stages or the development of subsequent generations, it can be considered an environmental memory. Thus, plant memory is a relevant mechanism by which plants respond adaptively to different environments. If the cost of maintaining the response is offset by its benefits, it may influence evolutionary trajectories. As such, plant memory has a sophisticated underlying molecular mechanism with multiple components and layers. Nonetheless, when mathematical modelling is combined with the knowledge of ecological, physiological, and developmental effects as well as the molecular mechanisms as a tool for understanding plant memory, the combined potential becomes unfathomable for the management of plant communities in natural and agricultural ecosystems. In this review, we summarize recent advances in the understanding of plant memory, discuss the ecological requirements for its evolution, outline the multilayered molecular network and mechanisms required for accurate and fail-proof plant responses to variable environments, point out the direct involvement of the plant metabolism and discuss the tremendous potential of various types of models to further our understanding of the plant's environmental memory. Throughout, we emphasize the use of plant memory as a tool to unlock the secrets of the natural world.
