“…Transporters of the NPF family are involved in translocation of a wide variety of nitrogenous compounds, including nitrate, nitrite, amino acids, oligopeptides, glucosinolates, plant hormones (auxin, abscisic acid, jasmonic acid) (summarized in Corratge-Faillié and Lacombe 2017; Jørgensen et al 2017) and several family members are active in roots (reviewed in Wang et al 2012). NPF transporters are therefore promising candidates for the exchange of nitrogenous compounds between AMF and their host plants.…”

Arbuscular mycorrhizal fungi (AMF) colonize up to 90% of all land plants and facilitate the acquisition of mineral nutrients by their hosts. Inorganic orthophosphate (P i ) and nitrogen (N) are the major nutrients transferred from the fungi to plants. While plant P i transporters involved in nutrient transfer at the plant-fungal interface have been well studied, the plant N transporters participating in this process are largely unknown except for some ammonium transporters (AMT) specifically assigned to arbuscule-colonized cortical cells. In plants, many nitrate transporter 1/peptide transporter family (NPF) members are involved in the translocation of nitrogenous compounds including nitrate, amino acids, peptides and plant hormones. Whether NPF members respond to AMF colonization, however, is not yet known. Here, we investigated the transcriptional regulation of 82 rice (Oryza sativa) NPF genes in response to colonization by the AMF Rhizophagus irregularis in roots of plants grown under five different nutrition regimes. Expression of the four OsNPF genes NPF2.2/ PTR2, NPF1.3, NPF6.4 and NPF4.12 was strongly induced in mycorrhizal roots and depended on the composition of the fertilizer solution, nominating them as interesting candidates for nutrient signaling and exchange processes at the plantfungal interface.

“…In legumes, limited data are available on NPFs, unlike with Arabidopsis thaliana in which 18 of the 53 AtNPF members have been characterized as nitrate and/or dipeptide transporters (see review by Wang et al 2012;Hsu and Tsay 2013). All those characterized as nitrate transporters are low-affinity nitrate transporters, except AtNPF6.8 (AtNRT1.1; CHL1) which is a dual-affinity nitrate transporter .…”

“…It is now accepted that the role of nitrate transporters extends beyond their function in the active uptake of nitrate from the environment (Wang et al 2012). Indeed, nitrate transporters are expressed in all plant organs, allowing both long-distance transport of nitrate, and tailored delivery to cell types.…”

Main conclusion The nitrate transporters, belonging to NPF and NRT2 families, play critical roles in nitrate signaling, root growth and nodule development in legumes.Nitrate plays an essential role during plant development as nutrient and also as signal molecule, in both cases working via the activity of nitrate transporters. To date, few studies on NRT2 or NPF nitrate transporters in legumes have been reported, and most of those concern Lotus japonicus and Medicago truncatula. A molecular characterization led to the identification of 4 putative LjNRT2 and 37 putative LjNPF gene sequences in L. japonicus. In M. truncatula, the NRT2 family is composed of 3 putative members. Using the new genome annotation of M. truncatula (Mt4.0), we identified, for this review, 97 putative MtNPF sequences, including 32 new sequences relative to previous studies. Functional characterization has been published for only two MtNPF genes, encoding nitrate transporters of M. truncatula. Both transporters have a role in root system development via abscisic acid signaling: MtNPF6.8 acts as a nitrate sensor during the cell elongation of the primary root, while MtNPF1.7 contributes to the cellular organization of the root tip and nodule formation. An in silico expression study of MtNPF genes confirmed that NPF genes are expressed in nodules, as previously shown for L. japonicus, suggesting a role for the corresponding proteins in nitrate transport, or signal perception in nodules. This review summarizes our knowledge of legume nitrate transporters and discusses new roles for these proteins based on recent discoveries.

“…S is assimilated from the soil mainly as sulfates (SO 4 2-), and the oxidation process involves microorganisms. N is mainly taken from the soil, and nitrate is the major form of absorption (Reif et al 2012;Wang et al 2012;Abbey et al 2002). Therefore the content of those elements are influenced by growth conditions, while ash content also varies greatly among biomass (Demirbas 2004).…”

Brazilian Lignocellulosic Wastes for Bioenergy Production: Characterization and Comparison with Fossil Fuels

et al. 2013

The aim of this paper was to analyze energy-related properties of forestry and agricultural wastes for energy production purposes, and to compare them with fossil fuels. The forestry wastes used were red cedar, Eucalyptus, and Pinus wood shavings. The agricultural wastes analyzed were rice husk, coffee wastes, sugar cane bagasse, maize harvesting wastes, and bamboo cellulose pulp. The forestry wastes presented more suitable properties for bioenergy production than the agricultural wastes. Desirable energetic properties were found for coffee wastes. The opposite was verified for rice husks. Among the biomass studied, coffee wastes presented the highest equivalent in fossil fuel volume and hence may lead to the highest decrease in CO 2 emissions by fossil fuels used in Brazil for steam and heat production. The results suggests that CO 2 benefits can be obtained if bioenergy is generated in the same locale where biomass is produced, avoiding CO 2 cost of logistics and leading to greater end-use efficiency. The present work promotes the widespread use of different lignocellulosic wastes for bioenergy production and gives useful information for the planning and the control of power plants using biomass.
