“…Nitrogen is taken up from the soil in inorganic forms, such as nitrate (NO 3 − ) and ammonium (NH 4 + ), as well as organic compounds (urea, amino acids, short peptides) [ 83 ]. NO 3 − uptake in roots is mediated by transporters belonging to NPF (NRT1/PTR) and NRT2 families [ 38 , 83 , 84 ]. It has been revealed by electrophysiological studies that nitrate uptake by roots is an active process that occurs via the 2H + /NO 3 − symport mechanism [ 38 , 85 ].…”

In plants, the plasma membrane proton pump (PM H+-ATPase) regulates numerous transport-dependent processes such as growth, development, basic physiology, and adaptation to environmental conditions. This review explores the multifunctionality of this enzyme in plant cells. The abundance of several PM H+-ATPase isogenes and their pivotal role in energizing transport in plants have been connected to the phenomena of pleiotropy. The multifunctionality of PM H+-ATPase is a focal point of numerous studies unraveling the molecular mechanisms of plant adaptation to adverse environmental conditions. Furthermore, PM H+-ATPase is a key element in plant defense mechanisms against pathogen attack; however, it also functions as a target for pathogens that enable plant tissue invasion. Here, we provide an extensive review of the PM H+-ATPase as a multitasking protein in plants. We focus on the results of recent studies concerning PM H+-ATPase and its role in plant growth, physiology, and pathogenesis.

In plants, the translocation of molecules, such as ions, metabolites, and hormones, between different subcellular compartments or different cells is achieved by transmembrane transporters, which play important roles in growth, development, and adaptation to the environment. To facilitate transport in a specific direction, active transporters that can translocate their substrates against the concentration gradient are needed. Examples of major active transporters in plants include ATP-binding cassette (ABC) transporters, multidrug and toxic compound extrusion (MATE) transporters, monosaccharide transporters (MSTs), sucrose transporters (SUTs), and amino acid transporters. Transport via ABC transporters is driven by ATP. The electrochemical gradient across the membrane energizes these secondary transporters. The pH in each cell and subcellular compartment is tightly regulated and yet highly dynamic, especially when under stress. Here, the effects of cellular and subcellular pH on the activities of ABC transporters, MATE transporters, MSTs, SUTs, and amino acid transporters will be discussed to enhance our understanding of their mechanics. The relation of the altered transporter activities to various biological processes of plants will also be addressed. Although most molecular transport research has focused on the substrate, the role of protons, the tiny counterparts of the substrate, should also not be ignored.

Objective: This study aims to determine the nutritional value and nutrient digestibility by in vitro of fodder sorghum (Sorghum bicolor (L.) Moench) from the effect of the addition of fermented urine fertilizer to the hydroponic media.Methods: The research used sorghum Numbu varieties grown hydroponically in the fodder phase, which was carried out in June - September 2020. The research treatments consist of water medium (T1), fermented urine 12.5 mL/L (T2) and 25 mL/L media (T3) with 4 replications. The urine fertilizer used was derived from fermented Ongole Crossbreed cow urine for 21 days. Fodder sorghum planted for 15 days. The results of the fodder harvest were analyzed by proximate and in vitro nutrient digestibility. Observation nutritional value parameters consists of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fiber (CF), total nutrient digestible (TDN), dry matter digestibility (DMD) and organic matter digestibility (OMD). Data were analyzed using one way ANOVA design, the significance by Duncan's Multiple Range Test.Results: The results showed that the addition of fermented urine had no effect on the DM, OM, and EE, but had a significant effect (P <0.05) on CP, CF, TDN and nutrient digestibility. The T2 and T3 treatments increased crude protein by 6.31% and 11.23% compared to T1. T3 treatment increased organic matter digestibility by 3.06% compared to T1.Conclusions: It can be concluded that the crude protein and organic matter digestibility of sorghum fodder at 15 days harvest stage, increases with the addition of fermented cattle urine up to 25.0 ml/L hydroponic media.
