“…As shown in Figure 1, no homologous LSU sequences were found in the genomes of ancient vascular plants such as Selaginella moellendorffii, non-vascular plants, or microalgae. This 3 of 12 result contrasts with the evolutionary history of other genes involved in the S-deficiency response, such as sulfate transporters, or genes encoding enzymes of S assimilation, such as ATP sulfurylase (APS) or APS reductase (APR), which are present in all Viridiplantae from microalgae to angiosperms (Figure 1) [17]. Furthermore, the family of the central transcriptional regulator of plant S-response, ETHYLENE-INSENSITIVE3-LIKE3 (EIL3), is present in all analyzed land plant genomes (Figure 1), indicating that the evolutionary appearance of LSU family is recent compared to other genes involved in the S-deficiency response [17].…”

“…The evolutionary history of the LSU gene family has recently been analyzed using genomic information from 134 plant species that include representatives of the major phylogenetic groups of the Viridiplantae clade [17]. The first notable finding of this study was that the LSU family probably originated from the common ancestor of seed plants [17]. As shown in Figure 1, no homologous LSU sequences were found in the genomes of ancient vascular plants such as Selaginella moellendorffii, non-vascular plants, or microalgae.…”

“…More recently, S-deficiency has been reported to also induces the expression of the LSU3 and LSU4 genes in Arabidopsis roots and leaves [17]. However, the degree of induction was not the same among members of this family: the induction of LSU4 by S-deficiency is lower than LSU1/2/3 LSU1/2/3 in both organs [17]. Furthermore, this study also showed that the mRNA levels of all tomato LSU genes and three wheat LSU genes increased by S-deficiency [17], supporting the idea that this gene family is associated with Sdeficiency and the response to this nutritional deficiency could be conserved in angiosperm plants.…”

LSUs (RESPONSE TO LOW SULFUR) are plant-specific proteins of unknown function that were initially identified during transcriptomic studies of the sulfur deficiency response in Arabidopsis. Recent functional studies have shown that LSUs are important hubs of protein interaction networks with potential roles in plant stress responses. In particular, LSU proteins have been reported to interact with members of the brassinosteroid, jasmonate signaling, and ethylene biosynthetic pathways, suggesting that LSUs may be involved in response to plant stress through modulation of phytohormones. Furthermore, in silico analysis of the promoter regions of LSU genes in Arabidopsis has revealed the presence of cis-regulatory elements that are potentially responsive to phytohormones such as ABA, auxin, and jasmonic acid, suggesting crosstalk between LSU proteins and phytohormones. In this review, we summarize current knowledge about the LSU gene family in plants and its potential role in phytohormone responses.

Sulfur (S) is an essential macronutrient for plants and its availability in soils is a relevant determinant for plant growth and development. Current regulatory policies aimed at reducing industrial S emissions and changes in agronomical practices have caused a decline in S contents in soils worldwide. Deficiency of sulfate — the primary form of S accessible to plants in soil — has adverse effects on both crop yield and nutritional quality. Therefore, recent research has increasingly focused on unraveling the molecular mechanisms through which plants detect and adapt to a limiting supply of sulfate. A significant part of these studies involves the use of omics technologies and has generated comprehensive catalogs of sulfate deficiency-responsive genes and processes, principally in Arabidopsis thaliana, with a few studies centering on crop species such as wheat, rice or members of the Brassica genus. Although we know that sulfate deficiency elicits an important reprogramming of the transcriptome, the transcriptional regulators orchestrating this response are not yet well understood. In this review, we summarize the knowledge on gene expression responses to sulfate deficiency and current efforts on the identification of transcription factors relevant for controlling this response. We further compare the transcriptional response and putative regulators between Arabidopsis thaliana and two relevant crop plants, rice and tomato, to gain insights into common mechanisms of response to sulfate deficiency.

Protein-protein interactions in plant antioxidant defense

The regulation of reactive oxygen species (ROS) levels in plants is ensured by mechanisms preventing their over accumulation, and by diverse antioxidants, including enzymes and nonenzymatic compounds. These are affected by redox conditions, posttranslational modifications, transcriptional and posttranscriptional modifications, Ca2+, nitric oxide (NO) and mitogen-activated protein kinase signaling pathways. Recent knowledge about protein-protein interactions (PPIs) of antioxidant enzymes advanced during last decade. The best-known examples are interactions mediated by redox buffering proteins such as thioredoxins and glutaredoxins. This review summarizes interactions of major antioxidant enzymes with regulatory and signaling proteins and their diverse functions. Such interactions are important for stability, degradation and activation of interacting partners. Moreover, PPIs of antioxidant enzymes may connect diverse metabolic processes with ROS scavenging. Proteins like receptor for activated C kinase 1 may ensure coordination of antioxidant enzymes to ensure efficient ROS regulation. Nevertheless, PPIs in antioxidant defense are understudied, and intensive research is required to define their role in complex regulation of ROS scavenging.
