Polyamines and flg22 reshape the ribosomal protein composition of actively translating ribosomes in plants Ester Murillo, Federico Martínez-Seidel, Kostadin E. Atanasov, Dione Gentry-Torfer, Alexandre Augusto Pereira Firmino, Alexander Erban, Shuai Nie, Michael G. Leeming, Pipob Suwanchaikasem, Berin A. Boughton, Nicholas A. Williamson, Ute Roessner, Joachim Kopka, Rubén Alcázar Plant Physiology and Biochemistry, 2025 Polyamines are small, polycationic molecules with amino groups that are present in most living organisms. Studies indicate that polyamines increase general protein synthesis and are essential for efficient translation. While progress has been made in understanding the role of polyamines in translation in bacteria and mammals, their contribution and mode of action in plants remain largely unexplored. In a previous study, we found that putrescine (Put) and the pathogen-associated molecular pattern (PAMP) from bacterial flagellin (flg22) transcriptionally induced ribosome biogenesis in plants. Here we examined the impact of polyamines (Put and spermine, Spm) and flg22 on ribosome complex formation in Arabidopsis. Our results indicate that polyamines, flg22 and their combinations increase the abundance of actively translating polysomes. Riboproteomic analyses revealed that polyamines and flg22 trigger differential changes in the accumulation of ribosomal proteins, which are structurally confined in response to Put. Importantly, Put was found binding to non-translating and actively translating ribosomes, suggesting that this polyamine has a role in functional aspects of translation, such as stabilization and/or remodeling of polysomal complexes. Additional global proteomics analyses in polyamine biosynthesis mutants revealed that lower Put availability triggers changes in proteins associated with ribonucleoprotein complex binding and biogenesis. Overall, our findings highlight the effect of polyamines and flg22 on shaping the ribosomal protein composition of actively translating ribosomes in plants. Changes in ribosomal protein composition of actively translating ribosomes are observed in treatments with polyamines, flg22 and their combinations in Arabidopsis, along with specific binding of polyamines to ribosome complexes. • Put, Spm, and their combinations with flg22 increase the abundance of actively translating polysomes. • Polyamines and flg22 reshape protein composition of translating polysomes. • Put triggered changes of ribosomal proteins are structurally confined within 40S subunit complexes. • Put preferentially binds to actively translational ribosome complexes. • Put deficiency alters the proteome and enriches for ribonucleoprotein binding proteins.
Pararhizobium sp. strains enhancing chilling stress tolerance and yield in tomato plants Lucía Díaz-Narváez, Kostadin E. Atanasov, Ester Murillo, Rubén Alcázar Plant Stress, 2024 In temperate climates, low temperatures represent a significant stressor that adversely affects crop yield and production. Tomato (Solanum lycopersicum L.) is a subtropical crop cultivated in temperate regions. However, most tomato cultivars are sensitive to chilling temperatures, which limit their cultivation in colder regions. Some microorganism-based plant biostimulants have been reported to enhance abiotic stress tolerance in crops. In this study, we isolated two Pararhizobium sp. strains (44 and 128) and tested their potential to trigger chilling stress tolerance in tomato. Through transcriptional, metabolic and biochemical analyses we demonstrate that inoculation with strains 44 and 128 enhance chilling stress tolerance by stimulating the ICE1-CBF-COR cold stress signaling pathway at transcriptional level, improving reactive oxygen species (ROS) detoxifying capacity and boosting the biosynthesis of stress-protective metabolites, such as polyamines and reduced glutathione (GSH). Treatment of tomato plants with these strains under non-stress conditions also increased tomato fruit weight and quality attributes. These findings suggest that Pararhizobium strains 44 and 128 could be valuable biostimulants for improving chilling stress tolerance and crop yield.
Spermine deficiency shifts the balance between jasmonic acid and salicylic acid-mediated defence responses in Arabidopsis Chi Zhang, Kostadin E. Atanasov, Ester Murillo, Vicente Vives‐Peris, Jiaqi Zhao, Cuiyun Deng, Aurelio Gómez‐Cadenas, Rubén Alcázar Plant Cell and Environment, 2023 Polyamines are small aliphatic polycations present in all living organisms. In plants, the most abundant polyamines are putrescine (Put), spermidine (Spd) and spermine (Spm). Polyamine levels change in response to different pathogens, including Pseudomonas syringae pv. tomato DC3000 (Pst DC3000). However, the regulation of polyamine metabolism and their specific contributions to defence are not fully understood. Here we report that stimulation of Put biosynthesis by Pst DC3000 is dependent on coronatine (COR) perception and jasmonic acid (JA) signalling, independently of salicylic acid (SA). Conversely, lack of Spm in spermine synthase (spms) mutant stimulated galactolipids and JA biosynthesis, and JA signalling under basal conditions and during Pst DC3000 infection, whereas compromised SA‐pathway activation and defence outputs through SA–JA antagonism. The dampening of SA responses correlated with COR and Pst DC3000‐inducible deregulation of ANAC019 expression and its key SA‐metabolism gene targets. Spm deficiency also led to enhanced disease resistance to the necrotrophic fungal pathogen Botrytis cinerea and stimulated endoplasmic reticulum (ER) stress signalling in response to Pst DC3000. Overall, our findings provide evidence for the integration of polyamine metabolism in JA‐ and SA‐mediated defence responses, as well as the participation of Spm in buffering ER stress during defence.
Tomato STEROL GLYCOSYLTRANSFERASE 1 silencing unveils a major role of steryl glycosides in plant and fruit development Angel Chávez, Nidia Castillo, Joan Manel López-Tubau, Kostadin E. Atanasov, Emma Fernández-Crespo, Gemma Camañes, Teresa Altabella, Albert Ferrer Environmental and Experimental Botany, 2023 Free and glycosylated sterols localize in the plant cell plasma membrane, where in combination with other lipids regulate its structure and function. The role of glycosylated sterols in regulating membrane-associated biological processes is more relevant in plants like tomato (Solanum lycopersicum), in which glycosylated sterols are the predominant sterols. A proper ratio of free sterols versus glycosylated sterols has proven to be essential for proper plant performance in several species, but almost nothing is known in tomato. To assess the role of glycosylated sterols in tomato plant and fruit development, we generated transgenic lines of tomato cultivar Micro-Tom expressing two different amiRNAs devised to silence STEROL GLYCOSYLTRANSFERASE 1, the most actively expressed of the four genes encoding sterol glycosyltransferases in this plant. STEROL GLYCOSYLTRANSFERASE 1 gene silencing caused moderate plant dwarfism and reduced fruit size. Analysis of the profile of glycosylated sterols throughout fruit development demonstrated that the maintenance of proper levels of these compounds during the early stages of fruit development is essential for normal fruit growth, since reduced levels of glycosylated sterols trigger a transcriptional downregulatory response that affects genes involved in processes that are critical for proper fruit development, such as seed filling, cell wall extension and auxin signaling.
Spermine inhibits PAMP-induced ROS and Ca2+burst and reshapes the transcriptional landscape of PAMP-Triggered immunity in Arabidopsis Chi Zhang, Kostadin E Atanasov, Rubén Alcázar Journal of Experimental Botany, 2023 Polyamines are small polycationic amines whose levels increase during defense. Previous studies support the contribution of the polyamine spermine to defense responses. However, the potential contribution of spermine to pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) has not been completely established. Here, we compared the contribution of spermine and putrescine to early and late PTI responses in Arabidopsis. We found that putrescine and spermine have opposite effects on PAMP-elicited reactive oxygen species (ROS) production, with putrescine increasing and spermine lowering the flg22-stimulated ROS burst. Through genetic and pharmacological approaches, we found that the inhibitory effect of spermine on flg22-elicited ROS production is independent of polyamine oxidation, nitric oxide, and salicylic acid signaling but resembles chemical inhibition of RBOHD (RESPIRATORY BURST OXIDASE HOMOLOG D). Spermine can also suppress ROS elicited by FLS2-independent but RBOHD-dependent pathways, thus pointing to compromised RBOHD activity. Consistent with this, we found that spermine but not putrescine dampens flg22-stimulated cytosolic Ca2+ influx. Finally, we found that both polyamines differentially reshape transcriptional responses during PTI and disease resistance to Pseudomonas syringae. Overall, we provide evidence for the differential contributions of putrescine and spermine to PTI, with an impact on plant defense.
Ammonium and nitric oxide condition the establishment of Arabidopsis Ler/Kas-2 immune-related hybrid incompatibility Kostadin Evgeniev Atanasov, Lucía C. Díaz-Narváez, Rubén Alcázar Planta, 2022 Main Conclusion High ammonium suppresses hybrid incompatibility between Ler and Kas-2 accessions through lowering nitric oxide levels and nitrate reductase activity required for autoimmunity. Abstract The immune-related hybrid incompatibility (HI) between Landsberg erecta (Ler) and Kashmir-2 (Kas-2) accessions is due to a deleterious genetic interaction between the RPP1 (RECOGNITION OF PERONOSPORA PARASITICA1)-like Ler locus and Kas-2 alleles of the receptor-like kinase SRF3 (STRUBBELIG RECEPTOR FAMILY 3). The genetic incompatibility is temperature-dependent and leads to constitutive activation of the salicylic acid (SA) pathway, dwarfism and cell death at 14–16 °C. Here we investigated the effect of nutrition on the occurrence of Ler/Kas-2 HI and found that high ammonium suppresses Ler/Kas-2 incompatible phenotypes independently of the ammonium/nitrate ratio. Ammonium feeding leads to compromised disease resistance to Pseudomonas syringae pv. tomato DC3000, lower total SA, nitric oxide and nitrate reductase activity in Ler/Kas-2 incompatible hybrids. In addition, we find that Ler/Kas-2 incompatibility is dependent on NPR1 (NONEXPRESSER OF PR GENES 1) and nitric oxide production. Overall, this work highlights the effect of nutrition on the expression of incompatible phenotypes independently of temperature.
Pseudomonas germanica sp. nov., isolated from Iris germanica rhizomes Kostadin Evgeniev Atanasov, David Miñana-Galbis, Julia Gallego, Annabel Serpico, Montserrat Bosch, Teresa Altabella, Albert Ferrer International Journal of Systematic and Evolutionary Microbiology, 2022 Through bacterial plant–endophyte extraction from rhizomes of Iris germanica plant, a Gram-stain-negative, aerobic, catalase- and oxidase-positive gammaproteobacterial strain, referred to as FIT28T, was isolated. FIT28T shows vigorous growth on nutrient rich media within the temperature range of 4–35 °C, with optimal growth at 28 °C, a wide pH tolerance from pH 5 to 11, and salt tolerance up to 6 % (w/v) NaCl. Colonies are white-yellow and quickly become mucoid. The results of analysis of the 16S rRNA gene sequence placed the strain within the genus Pseudomonas, and multilocus sequence analysis (MLSA) using 16S rRNA, rpoB, gyrB and rpoD concatenated sequences revealed that the closest relatives of FIT28T are Pseudomonas zeae OE48.2T, 'Pseudomonas crudilactis' UCMA 17988, Pseudomonas tensinigenes ZA5.3T, Pseudomonas helmanticensis OHA11T, Pseudomonas baetica a390T, Pseudomonas iridis P42T, Pseudomonas atagonensis PS14T and Pseudomonas koreensis Ps 9-14T, within the Pseudomonas koreensis subgroup of the Pseudomonas fluorescens lineage. The genome size of FIT28T is about 6.7 Mb with 59.09 mol% DNA G+C content. Average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values calculated from the genomic sequences of FIT28T, and the closely related P. zeae OE48.2T are 95.23 and 63.4 %, respectively. Biochemical, metabolic and chemotaxonomic studies further support our proposal that Pseudomonas germanica sp. nov., should be considered a novel species of the genus Pseudomonas. Hence, the type strain FIT28T (=LMG 32353T=DSM 112698T) has been deposited in public cell-type culture centres.
Pseudomonas fitomaticsae sp. nov., isolated at Marimurtra Botanical Garden in Blanes, Catalonia, Spain Kostadin Evgeniev Atanasov, David Miñana-Galbis, Deborah Cornadó, Annabel Serpico, Guiomar Sánchez, Montserrat Bosch, Albert Ferrer, Teresa Altabella International Journal of Systematic and Evolutionary Microbiology, 2022 In the framework of the research project called fitomatics, we have isolated and characterized a bacterial plant-endophyte from the rhizomes of Iris germanica, hereafter referred to as strain FIT81T. The bacterium is Gram negative, rod-shaped with lophotrichous flagella, and catalase- and oxidase-positive. The optimal growth temperature of strain FIT81T is 28 °C, although it can grow within a temperature range of 4–32 °C. The pH growth tolerance ranges between pH 5 and 10, and it tolerates 4% (w/v) NaCl. A 16S rRNA phylogenetic analysis positioned strain FIT81T within the genus Pseudomonas, and multilocus sequence analysis revealed that Pseudomonas gozinkensis IzPS32dT, Pseudomonas glycinae MS586T, Pseudomonas allokribbensis IzPS23T, 'Pseudomonas kribbensis' 46–2 and Pseudomonas koreensis PS9-14T are the top five most closely related species, which were selected for further genome-to-genome comparisons, as well as for physiological and chemotaxonomic characterization. The genome size of strain FIT81T is 6 492 796 base-pairs long, with 60.6 mol% of G+C content. Average nucleotide identity and digital DNA–DNA hybridization analyses yielded values of 93.6 and 56.1%, respectively, when the FIT81T genome was compared to that of the closest type strain P. gozinkensis IzPS32dT. Taken together, the obtained genomic, physiologic and chemotaxonomic data indicate that strain FIT81T is different from its closest relative species, which lead us to suggest that it is a novel species to be included in the list of type strains with the name Pseudomonas fitomaticsae sp. nov. (FIT81T=CECT 30374T=DSM 112699T).
Putrescine elicits ROS-dependent activation of the salicylic acid pathway in Arabidopsis thaliana Changxin Liu, Kostadin E. Atanasov, Nazanin Arafaty, Ester Murillo, Antonio F. Tiburcio, Jürgen Zeier, Rubén Alcázar Plant Cell and Environment, 2020 Polyamines are small amines that accumulate during stress and contribute to disease resistance through as yet unknown signaling pathways. Using a comprehensive RNA‐sequencing analysis, we show that early transcriptional responses triggered by each of the most abundant polyamines (putrescine, spermidine, spermine, thermospermine and cadaverine) exhibit specific quantitative differences, suggesting that polyamines (rather than downstream metabolites) elicit defense responses. Signaling by putrescine, which accumulates in response to bacteria that trigger effector triggered immunity (ETI) and systemic acquired resistance (SAR), is largely dependent on the accumulation of hydrogen peroxide, and is partly dependent on salicylic acid (SA), the expression of ENHANCED DISEASE SUSCEPTIBILITY (EDS1) and NONEXPRESSOR of PR GENES1 (NPR1). Putrescine elicits local SA accumulation as well as local and systemic transcriptional reprogramming that overlaps with SAR. Loss‐of‐function mutations in arginine decarboxylase 2 (ADC2), which is required for putrescine synthesis and copper amine oxidase (CuAO), which is involved in putrescine oxidation, compromise basal defenses, as well as putrescine and pathogen‐triggered systemic resistance. These findings confirm that putrescine elicits ROS‐dependent SA pathways in the activation of plant defenses.
The polyamine putrescine contributes to H2O2 and RbohD/F-dependent positive feedback loop in arabidopsis pamp-triggered immunity Changxin Liu, Kostadin E. Atanasov, Antonio F. Tiburcio, Rubén Alcázar Frontiers in Plant Science, 2019 Polyamines are involved in defense against pathogenic microorganisms in plants. However, the role of the polyamine putrescine (Put) during plant defense has remained elusive. In this work, we studied the implication of polyamines during pathogen-associated molecular pattern (PAMP) – triggered immunity (PTI) in the model species Arabidopsis thaliana. Our data indicate that polyamines, and particularly putrescine, accumulates in response to nonpathogenic P. syringae pv. tomato DC3000 hrcC and in response to the purified PAMP flagellin22. Exogenously supplied Put to Arabidopsis seedlings induces defense responses compatible with PTI activation, such as callose deposition and transcriptional up-regulation of several PTI marker genes. Consistent with this, we show that Put primes for resistance against pathogenic bacteria. Through chemical and genetic approaches, we find that PTI-related transcriptional responses induced by Put are hydrogen peroxide and NADPH oxidase (RBOHD and RBOHF) dependent, thus suggesting that apoplastic ROS mediates Put signaling. Overall, our data indicate that Put amplifies PTI responses through ROS production leading to enhanced disease resistance against bacterial pathogens.
