Abstract	Silicon (Si) improves plant growth and development especially under stress conditions. Although Si alleviates growth suppression and deficiency symptoms of several nutrient disorders, underlying regulatory processes have remained indefinite. Here, we analyzed the impact of Si on nutritional, metabolic and transcriptional responses in roots and shoots of barley subjected to potassium (K) deficiency. On the long run, Si nutrition improved root and shoot growth as well as metabolite homeostasis and partly reverted the K deficiency signature of the transcriptome back to adequate only in fully expanded leaves but hardly in roots. In the short term, Si supply to K-starved roots enhanced first the expression of the vacuolar K exporter KCO1 together with root-to-shoot translocation rates of rubidium (Rb) that was used as tracer for K. The typical K deficiency response, marked by upregulation of the K importer genes HAK1 and AKT1, set in a few days later but then at several-fold higher levels. Lower root K and higher shoot K contents in Si-supplied plants indicated more efficient remobilization of root K pools and higher root-to-shoot translocation, which on the long run restored K-dependent metabolic processes in shoots for the sake of continued assimilate provision to roots. These results provide a sequence of physiological processes by which Si partially recovers plants from K deficiency and indicate that Si interferes with systemic K deficiency signaling in roots to alter the regulation of K transporters.

Abstract	Strigolactones (SLs) are a class of phytohormones regulating branching/tillering, and their biosynthesis has been associated with nutritional signals and plant adaptation to nutrient-limiting conditions. The enzymes in the SL biosynthetic pathway downstream of carlactone are of interest as they are responsible for structural diversity in SLs, particularly cytochrome P450 CYP711A subfamily members, such as MORE AXILLARY GROWTH1 (MAX1) in Arabidopsis. We identified 13 MAX1 homologues in wheat, clustering in four clades and five homoeologous subgroups. The utilization of RNA-sequencing data revealed a distinct expression pattern of MAX1 homologues in above- and below-ground tissues, providing insights into the distinct roles of MAX1 homologues in wheat. In addition, a transcriptional analysis showed that SL biosynthetic genes were systematically regulated by nitrogen supply. Nitrogen limitation led to larger transcriptional changes in the basal nodes than phosphorus limitation, which was consistent with the observed tillering suppression, as wheat showed higher sensitivity to nitrogen. The opposite was observed in roots, with phosphorus limitation leading to stronger induction of most SL biosynthetic genes compared with nitrogen limitation. The observed tissue-specific regulation of SL biosynthetic genes in response to nutritional signals is likely to reflect the dual role of SLs as rhizosphere signals and branching inhibitors.

Abstract	Cereal-legume mixture is a well-known successful intercrop model for an efficient use of soil nutrients [1,2]. Effects of mineral N gradient on the acquisition of major nutrients: potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) is presented. A greenhouse pot experiment was conducted with wheat (Triticum aestivum L. cv. Lennox) and white lupin (Lupinus albus L. cv. Feodora) grown as sole crops and intercropped along a soil mineral N gradient obtained by ¹⁵N addition. Plants were harvested at flowering stage and dry weights of shoots and roots were measured. Potassium, calcium, magnesium and sulfur concentrations in shoots and roots were determined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

Abstract	Seaweed extracts are a category of biostimulant products that have the potential to promote plant growth and thus, have given a promise to develop more resilient systems of crop production that make efficient use of water and nutrients. This field study evaluated the effect of application timing of an Ascophyllum nodosum extract on nutrient uptake and grain yield of winter wheat when the extract was applied singly in five growth stages from 2017 to 2019. Analysis by orthogonal polynomial contrasts indicated that extract application significantly increased yield or biomass in all three site-years. Application at the tillering stage increased average yield by 17%, grain nutrient accumulation (N, P, K) by 21–24%, and N-use efficiency by 11% over the three site-year period, but extract effects were not consistent between site-years both in terms of optimal growth stages of application and magnitude of crop responses. While grain yield increased by 39% with extract application at tillering in 2017, yield gains ranging from 16 to 22% were obtained at the stem elongation and booting stages in 2018. These differences were likely the result of site-year variations in weather patterns and soil properties. Among macro-nutrients, only grain N accumulation was linearly correlated to grain yield across site-years indicating that increased soil N uptake and/or remobilization to the reproductive organs was a key process of the A. nodosum mode of action. An economic analysis indicated that the average return over extract cost was higher than that of the zero-extract control by €79-100 ha⁻¹ when the extract was applied at the tillering or stem elongation stage and assuming higher dilution rates recommended by the industry. Even greater economic benefits can result if N rates are substantially reduced without an adverse effect on yield gains.

Abstract	Being an essential macroelement, sulfur (S) is pivotal for plant growth and development, and acute deficiency in this element leads to yield penalty. Since the last decade, strong evidence has reported the regulatory function of silicon (Si) in mitigating plant nutrient deficiency due to its significant diverse benefits on plant growth. However, the role of Si application in alleviating the negative impact of S deficiency is still obscure. In the present study, an attempt was undertaken to decipher the role of Si application on the metabolism of rice plants under S deficiency. The results showed a distinct transcriptomic and metabolic regulation in rice plants treated with Si under both short and long-term S deficiencies. The expression of Si transporters

Abstract	It has been long recognized that silicon (Si) plays important roles in plant productivity by improving mineral nutrition deficiencies. Despite the fact that Si is considered as 'quasi-essential', the positive effect of Si has mostly been described in resistance to biotic and tolerance to abiotic stresses. During the last decade, much effort has been aimed at linking the positive effects of Si under nutrient deficiency or heavy metal toxicity (HM). These studies highlight the positive effect of Si on biomass production, by maintaining photosynthetic machinery, decreasing transpiration rate and stomatal conductance, and regulating uptake and root to shoot translocation of nutrients as well as reducing oxidative stress. The mechanisms of these inputs and the processes driving the alterations in plant adaptation to nutritional stress are, however, largely unknown. In this review, we focus on the interaction of Si and macronutrient (MaN) deficiencies or micro-nutrient (MiN) deficiency, summarizing the current knowledge in numerous research fields that can improve our understanding of the mechanisms underpinning this cross-talk. To this end, we discuss the gap in Si nutrition and propose a working model to explain the responses of individual MaN or MiN disorders and their mutual responses to Si supplementation.

Abstract	To date urea and ammonium are two nitrogen (N) forms widely used in agriculture. Due to a low production cost, urea is the N form most applied in agriculture. However, its stability in the soil depends on the activity of microbial ureases, that operate the hydrolysis of urea into ammonium. In the soil ammonium is subjected to fast volatilization in form of ammonia, an environmental N loss that contributes to the atmospheric pollution and impacts on farm economies. Based on these considerations, the optimization of N fertilization is useful in order to maximize N acquired by crops and at the same time limit N losses in the environment. The use of mixed nitrogen forms in cultivated soils allows to have urea and ammonium simultaneously available for the root acquisition after a fertilization event. A combination of different N-sources is known to lead to positive effects on the nutritional status of crops. It is plausible suppose that N acquisition mechanisms in plants might be responsive to N forms available in the root external solution, and therefore indicate a cross connection among different N forms, such as urea and ammonium.This DIB article provides details about the elemental composition and transcriptional changes occurring in maize seedlings when ammonium and urea mixture is applied to nutrient solution. An extensive and complete characterization of seedling response to urea and ammonium treatments is shown in the research article “Characterization of physiological and molecular responses of Zea mays seedlings to different urea-ammonium ratios” Buoso et al. [1].Maize seedlings were grown under hydroponic system with N applied to nutrient solution in form of urea and or ammonium, hence five different urea (U) to ammonium (A) ratios were tested (100U, 75U:25A, 50U:50A, 25U:75A, 100A). As control maize were fed with nitrate as sole N source, or were maintained in N deficiency (-N). After 1 or 7 days of N-treatment, maize seedlings were collected, and physiological and transcriptional analyses were performed on maize roots.Depending on nutritional treatment, no significant changes in seedling biomass were observed comparing N treatments. At both sampling times, an overall higher N accumulation in shoots and roots were detected when the inorganic N sources were applied to nutrient solutions (as ammonium or nitrate). ¹⁵N experiments indicated that in comparison to -N seedlings, urea fed seedlings showed an increase of N accumulation and data showed that ureic-N was taken up by seedlings in lower amounts than inorganic N-forms. Through EA-IRMS, ICP-OES and ICP-MS a multielemental composition of maize tissues was performed as well as gene expression analyses by Real-time RT-PCR that allowed to monitor the expression profile of genes most involved in urea and ammonium nutritional pathways.
