Resumen

Abstract Whilst many interactions with fungi are detrimental for plants, others are beneficial and result in improved growth and stress tolerance. Thus, plants have evolved sophisticated mechanisms to restrict pathogenic interactions while promoting mutualistic relationships. Numerous studies have demonstrated the importance of nitric oxide (NO) in the regulation of plant defence against fungal pathogens. NO triggers a reprograming of defence-related gene expression, the production of secondary metabolites with antimicrobial properties, and the hypersensitive response. More recent studies have shown a regulatory role of NO during the establishment of plant–fungal mutualistic associations from the early stages of the interaction. Indeed, NO has been recently shown to be produced by the plant after the recognition of root fungal symbionts, and to be required for the optimal control of mycorrhizal symbiosis. Although studies dealing with the function of NO in plant–fungal mutualistic associations are still scarce, experimental data indicate that different regulation patterns and functions for NO exist between plant interactions with pathogenic and mutualistic fungi. Here, we review recent progress in determining the functions of NO in plant–fungal interactions, and try to identify common and differential patterns related to pathogenic and mutualistic associations, and their impacts on plant health.

Resumen

The rhizosphere interaction between plant roots or pathogenic microbes is initiated by mutual exchange of signals. However, how soil pathogens sense host signals is largely unknown. Here, we studied early molecular events associated with host recognition in Fusarium graminearum, an economically important fungal pathogen that can infect both roots and heads of cereal crops. We found that host sensing prior to physical contact with plant roots radically alters the transcriptome and triggers nitric oxide (NO) production in F. graminearum. We identified an ankyrin-repeat domain containing protein (FgANK1) required for host-mediated NO production and virulence in F. graminearum. In the absence of host plant, FgANK1 resides in the cytoplasm. In response to host signals, FgANK1 translocates to the nucleus and interacts with a zinc finger transcription factor (FgZC1), also required for specific binding to the nitrate reductase (NR) promoter, NO production, and virulence in F. graminearum. Our results reveal mechanistic insights into host-recognition strategies employed by soil pathogens.

Resumen

Nitric oxide (NO) is involved in diverse physiological processes in plants, including growth, development, response to pathogens, and interactions with beneficial microorganisms. In this work, a dedicated microarray representing the widest database available of NO-related transcripts in plants has been produced with 999 genes identified by a cDNA amplified fragment length polymorphism analysis as modulated in Medicago truncatula roots treated with two NO donors. The microarray then was used to monitor the expression of NO-responsive genes in M. truncatula during the incompatible interaction with the foliar pathogen Colletotrichum trifolii race 1 and during the symbiotic interaction with Sinorhizobium meliloti 1021. A wide modulation of NO-related genes has been detected during the hypersensitive reaction or during nodule formation and is discussed with special emphasis on the physiological relevance of these genes in the context of the two biotic interactions. This work clearly shows that NO-responsive genes behave differently depending on the plant organ and on the type of interaction, strengthening the need to consider regulatory networks, including different signaling molecules.

Resumen

Phytopathogens have evolved diverse independent and complex modes of penetrating and accessing plant cellular contents. The synthesis of reactive oxygen or nitrogen species (ROS/RNS) by the utilization of molecular oxygen during plant–pathogen interactions results in to oxidative burst, a signaling cascade to defense. ROS array includes singlet oxygen, the hydroxyperoxyl radical, the superoxide anion, hydrogen peroxide, the hydroxyl radical and the closely related reactive nitrogen species, nitric oxide. ROS acts synergistically directs to signal amplification to drive the hypersensitive reaction (HR) and initiates systemicdefenses. The role of ROS in successful pathogenesis, it is ideal to inhibit the cell death machinery selectively and simultaneously to monitor other defense and pathogenesis-related processes. With the understanding of the interplay underlying the localized activation of the oxidative burst following perception of pathogen avirulence signals and key downstream responses including gene activation, cell death, and long-distance signaling, novel strategies will be developed for engineering enhanced protection against pathogens by manipulation of the oxidative burst and oxidant-mediated signal pathways. In this over review, it is reported the different roles of ROS/RNS in host–pathogen interactions with example on Alternaria- Sesamum interaction.

Resumen

Nitric oxide (NO) has recently gained interest as a major signaling molecule during plant development and response to environmental cues. Its role is particularly crucial for plant-pathogen interactions, during which it participates in the control of plant defense response and resistance. Indication for the presence of NO during symbiotic interactions has also been reported. Here, we defined when and where NO is produced during Medicago truncatula-Sinorhizobium meliloti symbiosis. Using the NO-specific fluorescent probe 4,5-diaminofluorescein diacetate, NO production was detected by confocal microscopy in functional nodules. NO production was localized in the bacteroid-containing cells of the nodule fixation zone. The infection of Medicago roots with bacterial strains impaired in nitrogenase or nitrite reductase activities lead to the formation of nodules with an unaffected NO level, indicating that neither nitrogen fixation nor denitrification pathways are required for NO production. On the other hand, the NO synthase inhibitor N-methyl-L-arginine impaired NO detection, suggesting that a NO synthase may participate to NO production in nodules. These data indicate that a NO production occurs in functional nodules. The location of such a production in fully metabolically active cells raises the hypothesis of a new function for NO during this interaction unrelated to defense and cell-death activation.

Resumen

Nitric oxide (NO) is crucial in animal– and plant–pathogen interactions, during which it participates in host defense response and resistance. Indications for the presence of NO during the symbiotic interaction between the model legume Medicago truncatula and its symbiont Sinorhizobium meliloti have been reported but the role of NO in symbiosis is far from being elucidated. Our objective was to understand the role or roles played by NO in symbiosis. As a first step toward this goal, we analyzed the bacterial response to NO in culture, using a transcriptomic approach. We identified approximately 100 bacterial genes whose expression is upregulated in the presence of NO. Surprisingly, most of these genes are regulated by the two-component system FixLJ, known to control the majority of rhizobial genes expressed in planta in mature nodules, or the NO-dedicated regulator NnrR. Among the genes responding to NO is hmp, encoding a putative flavohemoglobin. We report that an hmp mutant displays a higher sensitivity toward NO in culture and leads to a reduced nitrogen fixation efficiency in planta. Because flavohemoglobins are known to detoxify NO in numerous bacterial species, this result is the first indication of the importance of the bacterial NO response in symbiosis.

Resumen

Incompatible plant/pathogen interactions are often manifested as the hypersensitive response (HR), characterised by host cell death and rapid tissue collapse at the site of attempted infection. A key early response during the HR is the generation of reactive oxygen species (ROS), such as the superoxide anion ( 0; -) and hydrogen peroxide (H20 2), in an oxidative burst. The ROS produced during the oxidative burst have been implicated as cellular signalling molecules for the induction of defences responses including hypersensitive cell death. Increasing evidence exist that the free radical, nitric oxide (NO) also acts as a signalling molecule in plants during plant/pathogen interactions. The generation of NO in response to bacterial challenge, and the potential signalling pathways involved in H20 2- and NO-induced defence responses in Arabidopsis were therefore investigated Arabidopsis suspension cultures were found to generate elevated levels of NO and undergo cell death analogous to HR seen in planta, in response to challenge by avirulent bacteria. Using NO donors, elevated levels of NO were found to be sufficient to induce cell death independently of ROS, but not the expression of the defence-related genes PAL or GST. The NO-induced cell death was sensitive to inhibitors of RNA processing and protein synthesis, suggesting that NO-induced cell death is a form of programmed cell death (PCD), requiring the expression of at least one gene. However, the source of NO production by Arabidopsis remains to be elucidated, but appears to be independent of nitric oxide synthase-like activity. Pharmacological studies using specific inhibitors of mammalian mitogen activated protein kinase (MAPK) signalling cascades, and guanylate cyclase, the enzyme responsible for the production of second messenger cyclic guanosine monophosphate (cGMP), suggest that a MAPK signalling cascade acts downstream or independently of the oxidative burst to initiate H20 2-induced defence responses, while NO-induced cell death requires the production of cGMP in Arabidopsis. A number of studies have attempted to establish whether PCD induced during the HR in plants is similar to apoptotic cell death of anin1al cells. The key executioners of apoptosis in animal cells are caspases. NO was found to induce caspase-like activity in Arabidopsis cells, while a specific inhibitor of caspase-l blocked harpin-, H20 2- and NO-induced cell death. A characteristic of apoptosis is chromatin condensation and DNA fragmentation into nucleosomal fragments. Chromatin condensation was observed in Arabidopsis cells treated with the NO donor Roussin's black salt, but no DNA fragmentation was found in DNA extracted from cells treated with harpin, H20 2 or NO. In addition, random DNA degradation indicative of necrosis was found in DNA extracted from cells following avirulent bacterial challenge.

Resumen

Post-translational modification is an intracellular process that modifies the properties of proteins to extend the range of protein function without spending energy in de novo peptide synthesis. There are many post-translational modifications, for example, phosphorylation, ubiquitination, and S-nitrosylation. S-Nitrosylation is a post-translational modification which adds nitric oxide (NO) to sulfhydryl groups at cysteine residues to form S-nitrosothiol (SNO), and is required for plant immunity and fertility. Cellular NO changes between a pool of free NO and bound SNO. During pathogen infection, nitrosative stress in plants is mainly controlled by Snitrosothiolglutathione reductase (GSNOR) via the decomposition of GSNO. GSNOR is an alcohol dehydrogenase type 3 (ADH3) which has both GSNOR and formaldehyde dehydrogenase (FDH) activities. The roles of S-nitrosylation in mammals overlap with those in plants. This conservation led us to explore the relationship between S-nitrosylation, immune response, and fertility in Drosophila melanogaster as it might prove to be a good genetic model for further analysis of the role of S-nitrosylation in animals. I have identified fdh as the likely gsnor in D. melanogaster and have knocked this out using an overlapping deficiency technique in order to observe the effect on immunity and fertility. There are two main pathways in the Drosophila innate immune response, the Toll pathway for protecting against gram-positive bacteria and fungi, and the Imd pathway against gram-negative bacteria. I have investigated the effect of removing GSNOR on sensitivity to gramnegative bacteria (Escherichia coli and Erwinia carotovora) by septic and oral infection, and to fungi (Beauveria bassiana). Susceptibility to infection by the gram negative bacteria was similar to wild-type but susceptibility to B. bassiana was increased. This increase in susceptibility correlated with reduced anti-fungal antimicrobial peptide (AMP) production after B. bassiana infection. This suggests that GSNOR might be required for the normal activity of the Toll pathway or novel Toll-independent processes. We also observed that gsnor knockout impairs fertility and development of embryos.

Resumen

Since the discovery that Nitric oxide (NO) plays a crucial role in mediating plant defense response in the late nineties, extensive research over the past 20 years revealed that NO is acting as a mediator in plant growth and development, as well as coping with biotic and abiotic stresses. However, both NO biosynthesis and NO downstream signaling during the hypersensitive response triggered by an avirulent pathogen still need further clarification. Two routes for NO production in plants are known, the oxidative pathway and the reductive pathway. To date, the reductive route from nitrite is the most firmly described. Nitrate reductase (NR) can produce NO from nitrite but the physiological relevance of this activity is unclear. Furthermore, exogenous nitrite supply to an NR deficient mutant demonstrates that other routes for NO production from nitrite should exist in plants. Interestingly, it was reported that bovine carbonic anhydrase II, an alpha type carbonic anhydrase (CA), can convert nitrite to NO. Moreover, additional literature reports suggested the involvement of carbonic anhydrases belonging to the beta family of plant CAs in immunity. Therefore, the first aim of this work was to explore the possible involvement of plant carbonic anhydrase enzymes in nitric oxide synthesis during the hypersensitive response (HR). Firstly, we tried to explore the NO producing activity of AtαCA2, an Arabidopsis enzyme belonging to the same family as the bovine CA, which expression was induced by pathogen. We found that this protein requires glycosylation for its activity and localizes to plant thylakoids. Unfortunately, the transient expression in plant system, which yielded a properly glycosylated protein, led to low protein expression not enough to verify its NO production activity. Alternative production system should be eventually considered. Two representatives of β andγtype carbonic anhydrases were also cloned, expressed and purified. As expected, tobacco βCA1 showed high carbonic anhydrase activity, and Arabidopsis γCA2 showed no detectable carbonic anhydrase activity. However, these proteins were not able to catalyze the nitrite conversion to NO. In the second part of this work, we enquired the NO downstream signaling, focusing on transcriptomic changes associated to NO induced cell death. A massive transcriptomic rearrangement was found to be associated to the NO induced plant cell death. The functional class response to stimuli was strongly enriched in the differentially expressed genes modulated by NO. Moreover, we found a large modulation in signaling and transcription factors. Genes encoding for proteins involved in protein degradation or metabolism of nucleic acids were induced, while genes involved in anabolic processes were down-regulated. Importantly, we confirmed that NO treatment leads to a massive metabolic reprogramming, which specially affects lipid metabolism. Finally, among induced genes the enrichment in genes previously found to be involved/associated to cell death confirmed that chosen conditions were adequate to select for genes involved in cell death activation and execution during the HR.
