“…Plants take up nitrogen in the form of NO 3 -N (nitrate) or NH 4 -N (ammonium); therefore, the total N (nitrogen) absorbed usually consists of a combination of these two forms [16,17]. The ratio of NO 3 -N to NH 4 -N is of a great significance and can impact plant growth.…”

Abstract:Growing vegetables economically in the use of constructed wetland for wastewater treatment can play a role in overcoming water and food scarcity.Allium porrum L., Solanum melongena L., Ipomoea aquatica Forsk., and Capsicum annuum L. plants were selected to grow in hybrid constructed wetland (CW) under natural conditions. The impact of the ratio of nitrate to ammonium nitrogen on ammonium and nitrate nitrogen removal and on total nitrogen were studied in wastewater. Constructed wetland planted with Ipomoea aquatica Forsk. and Solanum melongena L. showed higher removal efficiency for ammonium nitrogen under higher ammonium concentration, whereas Allium porrum L.-planted CW showed higher nitrate nitrogen removal when NO 3 -N concentration was high in wastewater. Capsicum annuum L.-planted CW showed little efficiency for both nitrogen sources compared to other vegetables.

“…Rhizosphere microbiome composition and function vary with plant species/cultivar and are linked to plant ecological niche and nutrient requirements (Peiffer et al, 2013;Turner et al, 2013;Emmett et al, 2017). Plant-microbial partnerships jointly control processes such as aggregate formation, N cycling dynamics and the net balance between SOM decomposition and formation in the rhizosphere (Figure 3; Briones et al, 2003;Philippot et al, 2013;Emmett et al, 2020). For example, fast growing plant species, including crops such as maize, tend to be net mineralizers and accelerate decomposition and N cycling rates (Castro-Diez et al, 2014).…”

“…Conventionally cultivated rice is submerged, and nitrification is inhibited, NH 4 + is the main inorganic nitrogen in rhizosphere soil, therefore, rice is generally considered as ammonium-preferring plant (Arth et al, 1998;Kronzucker et al, 1999). However, for its well-developed aerial tissue, rice can transport and secrete oxygen from photosynthesis above ground to the rhizosphere (Aurelio et al, 2003). Oxygen can stimulate the growth and reproduction of nitrifying bacteria in the rhizosphere, so the part of NH 4 + in the rhizosphere can be nitrified into NO 3 - (Li et al, 2008).…”

“…Therefore, in the actual growth of rice, its root system has been in the mixed nutrition of NH 4 + and NO 3 - (Kirk and Kronzucker, 2005). Aurelio et al (2003) found that most rice varieties could absorb the same amount of NH 4 + and NO 3 -, and the amount of NO 3 absorbed by rice would be much larger than that of NH 4 + because of the strong nitrification in rhizosphere. During the late stage of rice growth and development, when it has been going through the process of long-term alternate wetting and drying irrigation or the whole growth stage of upland rice, the uptake of NO 3 was also higher than that of NH 4 + by rice (Arth et al, 1998;Wang et al, 2004).…”

Co-Overexpression of OsNAR2.1 and OsNRT2.3a Increased Agronomic Nitrogen Use Efficiency in Transgenic Rice Plants

The NO 3 - transporter plays an important role in rice nitrogen acquisition and nitrogen-use efficiency. Our previous studies have shown that the high affinity systems for nitrate uptake in rice is mediated by a two-component NRT2/NAR2 transport system. In this study, transgenic plants were successful developed by overexpression of OsNAR2.1 alone, OsNRT2.3a alone and co-overexpression of OsNAR2.1 and OsNRT2.3a . Our field experiments indicated that transgenic lines expressing p35S:OsNAR2.1 or p35S:OsNAR2.1-p35S:OsNRT2.3a constructs exhibited increased grain yields of approximately 14.1% and 24.6% compared with wild-type (cv. Wuyunjing 7, WT) plants, and the agricultural nitrogen use efficiency increased by 15.8% and 28.6%, respectively. Compared with WT, the 15 N influx in roots of p35S:OsNAR2.1 and p35S: OsNAR2.1-p35S:OsNRT2.3a lines increased 18.9%‑27.8% in response to 0.2 mM, 2.5 mM 15 NO 3 – , and 1.25 mM 15 NH 4 15 NO 3 , while there was no significant difference between p35S:OsNAR2.1 and p35S:OsNAR2.1-p35S:OsNRT2.3a lines; only the 15 N distribution ratio of shoot to root for p35S:OsNAR2.1-p35S:OsNRT2.3a lines increased significantly. However, there were no significant differences in nitrogen use efficiency, 15 N influx in roots and the yield between the p35S:NRT2.3a transgenic lines and WT. This study indicated that co-overexpression of OsNAR2.1 and OsNRT2.3a could increase rice yield and nitrogen use efficiency.
