“…In A. thaliana, peroxidase 34 (At3G49120) showed the most significant transcriptional up-regulation in response to SO 2 (Hamisch et al, 2012). Baillie et al (2019) proved that apoplastic Prx oxidise sulfite to sulfate, in the presence of phenolic compounds and hydrogen peroxide, thus acting as a first-line biochemical defence against toxic sulfite. Apoplastic and symplastic processes often act together in stress responses.…”

“…Common roles include (re-)organisation of the cell wall structure and participation in hormone-controlled developmental processes (Francoz et al, 2015;Kidwai et al, 2020). Moreover, plant Prxs are involved in pathogen defence, and are described to be important for ozone and sulfite detoxification (Francoz et al, 2015;Lüthje & Martinez-Cortes, 2018;Baillie et al, 2019;Kidwai et al, 2020). Pfanz et al (1990) demonstrated increased activity of apoplastic Prxs in sweet potato after fumigation with SO 2 .…”

In their environment, plants are exposed to a multitude of abiotic and biotic stresses that differ in intensity, duration and severity. As sessile organisms, they cannot escape these stresses, but instead have developed strategies to overcome them or to compensate for the consequences of stress exposure. Defence can take place at different levels and the mechanisms involved are thought to differ in efficiency across these levels. To minimise metabolic constraints and to reduce the costs of stress defence, plants prioritise first‐line defence strategies in the apoplastic space, involving ascorbate, defensins and small peptides, as well as secondary metabolites, before cellular processes are affected. In addition, a large number of different symplastic mechanisms also provide efficient stress defence, including chemical antioxidants, antioxidative enzymes, secondary metabolites, defensins and other peptides as well as proteins. At both the symplastic and the apoplastic level of stress defence and compensation, a number of specialised transporters are thought to be involved in exchange across membranes that still have not been identified, and information on the regeneration of different defence compounds remains ambiguous. In addition, strategies to overcome and compensate for stress exposure operate not only at the cellular, but also at the organ and whole‐plant levels, including stomatal regulation, and hypersensitive and systemic responses to prevent or reduce the spread of stress impacts within the plant. Defence can also take place at the ecosystem level by root exudation of signalling molecules and the emission of volatile organic compounds, either directly or indirectly into the rhizosphere and/or the aboveground atmosphere. The mechanisms by which plants control the production of these compounds and that mediate perception of stressful conditions are still not fully understood. Here we summarise plant defence strategies from the cellular to ecosystem level, discuss their advantages and disadvantages for plant growth and development, elucidate the current state of research on the transport and regeneration capacity of defence metabolites, and outline insufficiently explored questions for further investigation.

“…When analyzing the transcriptome of At-SOX knock-out plants and comparing it to the wild-type control, we observed remarkable and broad regulative responses at the mRNA level, especially in transcripts related to sulfur metabolism enzymes, as well as in those related to stress response and senescence ( [88]). These omics analyses identified two novel candidates for involvement in SO 2 detoxification beyond SOX: an apoplastic peroxidase (a heme-enzyme) that shows sulfite oxidation activity [89], and defensins as putative cysteine mass storages [88].…”

Sulfite oxidase is one of five molybdenum-containing enzymes known in eukaryotes where it catalyzes the oxidation of sulfite to sulfate. This review covers the history of sulfite oxidase research starting out with the early years of its discovery as a hepatic mitochondrial enzyme in vertebrates, leading to basic biochemical and structural properties that have inspired research for decades. A personal view on sulfite oxidase in plants, that sulfates are assimilated for their de novo synthesis of cysteine, is presented by Ralf Mendel with numerous unexpected findings and unique properties of this single-cofactor sulfite oxidase localized to peroxisomes. Guenter Schwarz connects his research to sulfite oxidase via its deficiency in humans, demonstrating its unique role amongst all molybdenum enzymes in humans. In essence, in both the plant and animal kingdoms, sulfite oxidase represents an important player in redox regulation, signaling and metabolism, thereby connecting sulfur and nitrogen metabolism in multiple ways.

“…Oxidative detoxification into sulfate was also found in another strategy, with or without increased sulfite oxidase activity. Baillie et al (2019) [77] provided new insights into sulfite detoxification, as they found apoplastic peroxidases that enable additional sulfite detoxification, acting as a first line of defense upon exposure to SO 2 . Sulfite detoxification is of utmost importance in plants, and it has been found that the sulfite concentration is strictly controlled.…”

Sulfate is taken up from the soil solution by the root system; and inside the plant, it is assimilated to hydrogen sulfide, which in turn is converted to cysteine. Sulfate is also taken up by the leaves, when foliage is sprayed with solutions containing sulfate fertilizers. Moreover, several other sulfur (S)-containing compounds are provided through foliar application, including the S metabolites hydrogen sulfide, glutathione, cysteine, methionine, S-methylmethionine, and lipoic acid. However, S compounds that are not metabolites, such as thiourea and lignosulfonates, along with dimethyl sulfoxide and S-containing adjuvants, are provided by foliar application—these are the S-containing agrochemicals. In this review, we elaborate on the fate of these compounds after spraying foliage and on the rationale and the efficiency of such foliar applications. The foliar application of S-compounds in various combinations is an emerging area of agricultural usefulness. In the agricultural practice, the S-containing compounds are not applied alone in spray solutions and the need for proper combinations is of prime importance.
