“…The common participation of similar signals, like ethylene, NO and auxin, in the induction of their responses, could be related to the existence of crosstalk among nutrient deficiencies (reviewed in [3]). According to this view, ethylene, besides P and Fe deficiency responses, is also implicated in the induction of responses to K deficiency [138], to S deficiency [139,140], and to other deficiencies ( [3] and references therein). Recently, Rai et al [141] demonstrated the potential roles of auxin and Zinc (Zn) in mediating local Pi deficiency responses of the root system during growth under different Fe regimes, supporting the existence of crosstalk between Pi, Fe and Zn for maintaining Pi homeostasis.…”

This review deals with two essential plant mineral nutrients, iron (Fe) and phosphorus (P); the acquisition of both has important environmental and economic implications. Both elements are abundant in soils but are scarcely available to plants. To prevent deficiency, dicot plants develop physiological and morphological responses in their roots to specifically acquire Fe or P. Hormones and signalling substances, like ethylene, auxin and nitric oxide (NO), are involved in the activation of nutrient-deficiency responses. The existence of common inducers suggests that they must act in conjunction with nutrient-specific signals in order to develop nutrient-specific deficiency responses. There is evidence suggesting that P-or Fe-related phloem signals could interact with ethylene and NO to confer specificity to the responses to Fe-or P-deficiency, avoiding their induction when ethylene and NO increase due to other nutrient deficiency or stress. The mechanisms responsible for such interaction are not clearly determined, and thus, the regulatory networks that allow or prevent cross talk between P and Fe deficiency responses remain obscure. Here, fragmented information is drawn together to provide a clearer overview of the mechanisms and molecular players involved in the regulation of the responses to Fe or P deficiency and their interactions.

“…In the last 10 years, increased ethylene production by roots and/or shoots has been described for other nutrient deficiencies, such as K (Shin and Schachtman, 2004;Benlloch-González et al, 2010), S (Zuchi et al, 2009;Moniuszko et al, 2013), N (Zheng et al, 2013), and Mg (Hermans et al, 2010). The higher ethylene production described for nutrient deficiencies has been further supported by results showing up-regulation of genes implicated in ethylene synthesis.…”

Ethylene has also been implicated in both N deficiency and excess Mohd-Radzman et al, 2013;Zheng et al, 2013), and its participation in Mg deficiency has been suggested (Hermans et al, 2010).…”

IntroductionSulfur is an essential macronutrient for plant growth and development. It is found in amino acids such as cysteine and methionine, thiols of proteins, glutathione, secondary products, peptides, cofactors, membrane sulfolipids, cell walls, and hormones. ATP sulfurylase, adenosine 5'-phosphosulfate, phosphorylation to 3'-phosphoadenosine 5'-phosphosulfate, and sulfite reductase are major enzymes in the sulfate assimilation pathway (Saito, 2004;Takahashi et al., 2011). Sulfur compounds play roles in responses to abiotic and biotic stress, including drought and salinity stresses, detoxification of reactive oxygen species, and production of glucosinolates in defense against herbivores and other pathogens (Davidian and Kopriva, 2010;Gallardo et al., 2014). Sulfur is mainly taken up by plants as inorganic sulfate (SO 4 2−) and then converted to sulfite (SO 3 2− ) and sulfide (S 2− ). Later, assimilation into cysteine is accepted to be the major point of the natural sulfur cycle (Buchner et al., 2004). Gene expression data of S nutrition are available for Arabidopsis thaliana (Hirai et al., 2003), poplar (Honsel et al., 2012), and tobacco (Lewandowska et al., 2005Wawrzynska et al., 2005). In A. thaliana, 4 members of the plant-specific LSU (response to Low SUlfur) gene family (LSU1-4) have been found. LSU1 is considered a significant connector in the gene-metabolite hormone-related network for S response, but there is no experimental evidence related to this gene (Nikiforova et al., 2005). The LSU1 (At3g49580) and LSU3 (At3g49570) genes are localized on chromosome 3, separated by a distance of about 2250 bp, while LSU2 (At3g49580) and LSU4 (At5g24660) are on chromosome 5, separated by about 2060 bp (Sirko et al., 2015). S deficiency and some environmental conditions such as salt stress and AgNO 3 treatment have been reported to induce the LSU1 and LSU2 genes (Zimmermann et al., 2004(Zimmermann et al., , 2008. LSU2 was also induced by oxidative stress (Davletova et al., 2005), by carbon starvation, and in response to sugar (Usadel et al., 2008). The Arabidopsis LSU2 gene has been temporarily determined as one of the genes cross-talking between Abstract: Sulfur (S) affects the plant life cycle and crop yield and has nutritional importance for human and animal diet. Its deficiency is one of the major problems in agriculture. However, the plant-specific LSU (response to Low SUlfur) gene family has not been extensively analyzed in major plant species such as grasses. In this study, we have performed in silico genome-wide analysis of LSU genes in 6 grass species, including Brachypodium distachyon, Sorghum bicolor, Oryza sativa, Zea mays, Triticum aestivum, and Panicum virgatum. All identified LSU genes contained one exon encoding proteins of acidic character with cytoplasmic localization. In silico analysis of ciselements revealed that sulfur-responsive elements (SURE boxes, SUlfur Response Element, GAGAC motif) were present in all LSU genes. In phylogenetic analysis, dicot and monocot LSU genes were separated. E...
