“…These results confirmed that AM symbiosis was able to provide specific adaptation mechanisms to the host plant to tolerate long-term K + deprivation. ROS have been detected in legume roots colonized by both AM fungi and nitrogen-fixing bacteria, particularly in colonized cells (Salzer et al, 1999;Fester and Hause, 2005;Puppo et al, 2013). Moreover, some NADPH oxidase-encoding genes were recently found to be up-regulated in colonized cortical cells of M. truncatula roots, suggesting their role in arbuscule development (Belmondo et al, 2016a(Belmondo et al, , 2016b.…”

Arbuscular mycorrhizal (AM) associations enhance the phosphorous and nitrogen nutrition of host plants, but little is known about their role in potassium (K + ) nutrition. Medicago truncatula plants were cocultured with the AM fungus Rhizophagus irregularis under high and low K + regimes for 6 weeks. We determined how K + deprivation affects plant development and mineral acquisition and how these negative effects are tempered by the AM colonization. The transcriptional response of AM roots under K + deficiency was analyzed by whole-genome RNA sequencing. K + deprivation decreased root biomass and external K + uptake and modulated oxidative stress gene expression in M. truncatula roots. AM colonization induced specific transcriptional responses to K + deprivation that seem to temper these negative effects. A gene network analysis revealed putative key regulators of these responses. This study confirmed that AM associations provide some tolerance to K + deprivation to host plants, revealed that AM symbiosis modulates the expression of specific root genes to cope with this nutrient stress, and identified putative regulators participating in these tolerance mechanisms.

“…The establishment of the symbiosis is highly specific, as a rhizobia species will only interact with a specific legume species. Specificity is greatly influenced by the Nod signalling pathway [30], but H 2 O 2 and † NO also play a role in the proximal mechanisms associated with the specific establishment of the symbiosis [31]. Indeed, in the common bean Phaseolus vulgaris, the contact of roots with NF rapidly triggers a transient burst of intracellular ROS at the tip of the hairs [32].…”

“…From the bacterial point of view, transgenic S. meliloti unable to scavenge † NO are less competitive than wild-type rhizobia in the nodulation process [37], suggesting that † NO is necessary for an optimal establishment of the association. Similar to the squid-vibrio symbiosis [27], it has been proposed that the initial exposure to † NO primes the symbionts to resist against stressful conditions encountered during later symbiotic stages [31].…”

The oxidative environment: a mediator of interspecies communication that drives symbiosis evolution

Symbiotic interactions are ubiquitous in nature and play a major role in driving the evolution of life. Interactions between partners are often mediated by shared signalling pathways, which strongly influence both partners' biology and the evolution of the association in various environments. As an example of 'common language', the regulation of the oxidative environment plays an important role in driving the evolution of symbiotic associations. Such processes have been occurring for billions of years, including the increase in Earth's atmospheric oxygen and the subsequent evolution of mitochondria. The effect of reactive oxygen species and reactive nitrogen species (RONS) has been characterized functionally, but the molecular dialogue between partners has not been integrated within a broader evolutionary context yet. Given the pleiotropic role of RONS in cell-cell communication, development and immunity, but also their associated physiological costs, we discuss here how their regulation can influence the establishment, the maintenance and the breakdown of various symbiotic associations. By synthesizing recent developments in redox biology, we aim to provide an interdisciplinary understanding of the influence of such mediators of interspecies communication on the evolution and stability of symbioses, which in turn can shape ecosystems and play a role in health and disease.

“…Then, in 1979, Keppler (1979) reported that plants treated with different herbicides can generate NO [7]. However during the 1990s, NO research was extended to plant cells, this molecule being involved in a wide spectrum of functions during plant growth and development, as well as in the mechanism of interaction with beneficial microorganisms, defenses against pathogens, and adverse environmental stresses [8][9][10][11]. The main goal of this work is to provide a brief overview of the relevance of NO and derived molecules designated as reactive nitrogen species (RNS) in higher plants.…”

Nitric oxide (NO) is a free radical and a component of the N-cycle. Nevertheless, NO is likewise endogenously produced inside plant cells where it participates in a myriad of physiological functions, as well as in the mechanism of response against abiotic and biotic stresses. At biochemical level, NO has a family of derived molecules designated as reactive nitrogen species (RNS) which finally can interact with different bio-macromolecules including proteins, lipids, and nucleic acids affecting their functions. The present review has the goal to provide a comprehensive and quick overview of the relevance of NO in higher plants, especially for those researchers who are not familiar in this research area in higher plants.
