menadione Sodium Bisulphite msb beyond seed soaking root pretreatment with msb primes salt stress tolerance in tomato plants
Environmental and Experimental Botany, 2019Co-Authors: David Jimenezarias, Francisco J Garciamachado, Sarai Moralessierra, Emma Suarez, Jose A Perez, Juan C Luis, Cristina Garridoorduna, Antonio J Herrera, Francisco Valdes, Luisa M SandalioAbstract:Abstract Salinity and drought are considered significant abiotic plant stressors with major impact on plant development that causes serious agricultural yield losses. Amongst the strategies to face this problem, the use of compounds capable of inducing abiotic stress tolerance is still little explored. Menadione Sodium Bisulphite (MSB), a water-soluble vitamin K3 derivative, was previously shown to prime salt stress tolerance when Arabidopsis seeds were pre-soaked with this compound. However, this method has some technical problems regarding seed storage and longevity. In order to overcome these handicaps, we assessed the effect of supplying MSB to roots to prime the response to salinity stress, analysing the effect of two NaCl concentrations (100 and 150 mM). We selected tomato plants, the most economically important horticultural crop, as our biological model. In this new system, MSB primes salt tolerance in tomato plants by improving net photosynthesis, regulating stomatal aperture and maintaining water balance. Furthermore, MSB induces a faster proline accumulation and ion homeostasis by up-regulating several ion transporter genes, and increases antioxidant activity. As a result, a clear positive effect on plant growth was observed, indicated by the relative growth rate (RGR), These findings again highlight the potential usefulness of MSB as a priming agent for enhancing crop tolerance in the field under adverse environmental conditions.

menadione Sodium Bisulphite msb enhances the resistance response of tomato leading to repel mollusc pests
Pest Management Science, 2016Co-Authors: Estefania Carrilloperdomo, David Jimenezarias, Angel Aller, Andres A BorgesAbstract:BACKGROUND: Snails and slugs are terrestrial gastropods representing an important biotic stress that adversely affects crop yields. These pests are typically controlled with molluscicides, which produce pollution and toxicity and further induce the evolution of resistance mechanisms, making pest management even more challenging. In our work, we have assessed the efficacy of two different plant defence activators, menadione Sodium Bisulphite (MSB) and 1,2,3-benzothiadiazole-7-thiocarboxylic acid S-methyl ester (BTH), as inducers of resistance mechanisms of the model plant for defence, Solanum lycopersicum, against the generalist mollusc Theba grasseti (Helicidae). The study was designed to test the feeding behaviour and choice of snails, and also to analyse the expression profile of different genes specifically involved in defence against herbivores and wounds. RESULTS: Our data suggest that, through the downregulation of the terpene volatile genes and the production of proteinase inhibitors, treated MSB plants may be less apparent to herbivores that use herbivore-induced plant volatiles for host location. By contrast, BTH was not effective in the treatment of the pest, probably owing to an antagonistic effect derived from the induction of both salicylic-acid-dependent and jasmonic-acid-dependent pathways. CONCLUSIONS: This information is crucial to determine the genetic basis of the choice of terrestrial gastropod herbivores in tomato, providing valuable insight into how the plant defence activators could control herbivore pests in plants. Our work not only reports for the first time the interaction between tomato and a mollusc pest but also presents the action of two plant defence inductors that seems to produce opposed responses by inducing resistance mechanisms through different defence pathways. © 2015 Society of Chemical Industry Supporting information may be found in the online version of this article.

priming effect of menadione Sodium Bisulphite against salinity stress in arabidopsis involves epigenetic changes in genes controlling proline metabolism
Environmental and Experimental Botany, 2015Co-Authors: David Jimenezarias, Andres A Borges, Juan C Luis, Francisco Valdes, Luisa M Sandalio, Jose A PerezAbstract:Abstract Plants are able to develop numerous defence strategies to face stress. Amongst these, higher plants are capable of demonstrating stress imprint, a mechanism related with the phenomenon of priming. This is usually defined as genetic or biochemical modifications induced by a first stress exposure that leads to enhanced resistance to a later stress. Menadione Sodium Bisulphite (MSB), a water-soluble addition compound of vitamin K3, was first studied as a plant growth regulator and has been later widely shown to function as plant defence activator against several pathogens in a number of plant species. We recently reported that treating Arabidopsis seeds with MSB primes salt tolerance by inducing an early acclimation to salt stress. Here we describe the analysis of the effect of MSB on cytosine methylation in a salt stress background demonstrating that one of the mechanisms underlying this early acclimation to salt stress is an epigenetic mark. Specifically, MSB leads to a hypomethylation state at the promoter region of genes involved in the biosynthesis (P5CS1) and degradation (ERD5) of proline, affecting mainly CHG and CHH sites(where H is any nucleotide except G). The epigenetic changes detected are correlated with the observed expression patterns of P5CS1 (upregulation) and ERD5 (downregulation) genes and the increase in proline accumulation.

treating seeds in menadione Sodium Bisulphite primes salt tolerance in arabidopsis by inducing an earlier plant adaptation
Environmental and Experimental Botany, 2015Co-Authors: David Jimenezarias, Jose A Perez, Juan C Luis, Vanesa Martinrodriguez, Francisco Valdesgonzalez, Andres A BorgesAbstract:Abstract For the majority of crops, salinity is one of the most important abiotic stresses, since about 20% of irrigated agricultural land is adversely affected by it. Menadione Sodium Bisulphite (MSB), a water-soluble vitamin K3 o menadione derivative, has been previously reported as a plant defence activator against several pathogens in a number of species. We have further explored the MSB effects on salt tolerance. In this study, Arabidopsis thaliana wild ecotype Col-0 plants were exposed to prolonged salt (50 mM) stress. Salt treatment resulted in severe growth inhibition. This detrimental effect was lower in terms of relative growth rate (RGR) in plants from seeds soaked in 20 mM of MSB. In these plants, the drop in RGR was nearly 30% lower than untreated plants after 7 days in salt. Furthermore, we found that the salt stress imposed was not enough to disturb photosystem II or induce the expression of several detoxification genes. These functional impairments are characteristic of ionic injuries due to high levels of reactive oxygen species (ROS). At the end of the second week of the experiment, salt-treated plants recover RGR levels close to those of the control. Under our experimental conditions plants seem to be challenged by an osmotic stress with a minimum ionic imbalance. Those from MSB-treated seeds were primed to induce an earlier proline accumulation. Although no significant expression of ROS detoxification genes was found, several transcription factors involved in ROS signalling were detected after salt addition. In this context, MSB treatment was able to prime these transcription factors, resulting in an early adaptation of plants in response to salt stress.

induced resistance to fusarial wilt of banana by menadione Sodium Bisulphite treatments
Crop Protection, 2004Co-Authors: Andres A Borges, Andres Borgesperez, Marino FernandezfalconAbstract:Abstract The soilborne fungus Fusarium oxysporum f.sp. cubense is the causal agent of banana vascular wilt disease named Panama disease and one of the most serious threats to banana crops worldwide. A water-soluble addition compound of vitamin K3, menadione Sodium Bisulphite (MSB), first studied as a plant growth regulator, has recently been shown to induce resistance against Panama disease. Effective fungicides are not yet available to control this fatal disease. Here we report on two independent long-term experiments leading to the enhanced resistance response induced by MSB. The results demonstrated that MSB is an effective resistance activator in banana, and a potentially useful agent for the control of Panama disease.
