Abstract:
ABSTRACT Glutamate dehydrogenase (GDH) and glutamine synthetase (GS)–glutamine 2-oxoglutarate-aminotransferase (GOGAT) represent the two main pathways of ammonium assimilation in Corynebacterium glutamicum. In this study, the ammonium assimilating fluxes in vivo in the wild-type ATCC 13032 strain and its GDH mutant were quantitated in continuous cultures. To do this, the incorporation of15N label from [15N]ammonium in glutamate and glutamine was monitored with a time resolution of about 10 min with in vivo 15N nuclear magnetic resonance (NMR) used in combination with a recently developed high-cell-density membrane-cyclone NMR bioreactor system. The data were used to tune a standard differential equation model of ammonium assimilation that comprised ammonia transmembrane diffusion, GDH, GS, GOGAT, and glutamine amidotransferases, as well as the anabolic incorporation of glutamate and glutamine into biomass. The results provided a detailed picture of the fluxes involved in ammonium assimilation in the two different C. glutamicumstrains in vivo. In both strains, transmembrane equilibration of 100 mM [15N]ammonium took less than 2 min. In the wild type, an unexpectedly high fraction of 28% of the NH4 + was assimilated via the GS reaction in glutamine, while 72% were assimilated by the reversible GDH reaction via glutamate. GOGAT was inactive. The analysis identified glutamine as an important nitrogen donor in amidotransferase reactions. The experimentally determined amount of 28% of nitrogen assimilated via glutamine is close to a theoretical 21% calculated from the high peptidoglycan content of C. glutamicum. In the GDH mutant, glutamate was exclusively synthesized over the GS/GOGAT pathway. Its level was threefold reduced compared to the wild type.

Abstract:
The uptake of nitrate and ammonium by a terrestial (Bromheadia finlaysonia) and an epiphytic (Dendrobium hybrid) orchid in solution culture has been studied. The rates of nitrate and ammonium were relatively linear, with higher rate of uptake for ammonium. The rates of nitrate uptake in terrestial and epiphytic orchids were 0.4 and 0.9 μmole gm fw-1 hr-1 respectively and they were considerably lower than those of most major crops. SEM studies show that the velamen of Bromheadia was 2 cells thick whereas that of Dendrobium was 8-10 cells thick. It is unlikely that the velamen is the major factor in restricting influx of nitrate or ammonium. Nitrate reductase (NR) and glutamine synthetase (GS) were present in roots and leaves of both orchids. NR was high in roots but low in leaves. The reverse was for GS. The activities of NR and GS was low but high enough to account for the rate of nitrate or ammonium uptake. It appears that the movement of ions across the transfer junction at the exodermis plays a major regulatory role in ion uptake by orchid root.

Abstract:
We applied 15N-labeled ammonium and nitrate to individual branches of red spruce (Picearubens Sarg.) to examine the importance of canopy N assimilation in the field. Levels of labeled N were highest in the youngest foliage and youngest twigs, and twig ammonium assimilation exceeded nitrate assimilation. Approximately 5% of the ammonium and 1% of the nitrate applied to each branch was assimilated; because of throughfall interactions with multiple branches, canopy assimilation rates are expected to be 3–6 times larger. Twig 15N levels exceeded foliar levels for the younger age-classes in the ammonium-labeled treatments, suggesting that twigs play an important role in ammonium assimilation. Comparisons of these results with data from trees that assimilated 15N through their roots showed that the pattern of canopy N assimilation differs from root assimilation, primarily by the assimilation of large amounts of N by twigs. Our results directly demonstrate for the first time that canopy assimilation is a pathway for uptake of N in these high-elevation trees. Canopy assimilation of atmospherically deposited N may represent 2–8% of the total N requirement for spruce in the high-elevation forest. While canopy N assimilation may thus reflect only a minor anthropogenic alteration of N acquisition in these forests, the long-term fate of this N needs to be determined.

Abstract:
Saccharomyces cerevisiae can assimilate ammonium by NADP-GDH or by GS-GOGAT. The aim of this project was to improve the efficiency of ammonium assimilation, and therefore substrate utilisation, of S. cerevisiae by elimination of the energy inefficient pathway (GS-GOGAT). GOGAT- mutants were isolated from a GDH- parent strain by their inability to use ammonium as sole nitrogen source. Two structural gene mutants were identified, one in each of the two structural genes encoding GOGAT. Constructs with different combinations of GDH- and GOGAT- mutations and corresponding wild type alleles were made, and their growth studied in medium supplemented with different levels of ammonium. The growth properties (as final culture density and growth rate) of GOGAT- and GOGAT+ strains transformed with the GDH1 gene, and grown with excess ammonium were very similar. It was concluded that, under the conditions used in this study, the loss of GOGAT does not improve the growth properties of the strain. Non-transformed constructs were grown with excess and limiting ammonium. Growth properties of the GDH- and GOGAT- strains suggest that GS-GOGAT functions in ammonium assimilation at very low ammonium levels. This conclusion needs further investigation because the GDH+ GOGAT- construct had lower NADP-GDH activity than the wild type. The physiology of ammonium assimilation by two industrial strains was compared to that of a laboratory wild type at different ammonium concentrations using shake-flask culture. All three strains possessed the three activities in MM+20mM NH4+, and the profiles of appearance/disappearance of activity were very similar. At lower ammonium concentrations, important differences between the strains became apparent. It is unclear if it is due to simple strain heterogeneity or represents significant differences between industrial and laboratory strains. On the basis of the enzyme data, GS-GOGAT appears to be important in ammonium assimilation by DCL1 at limiting concentrations.

Bibliography: pages 98-112.
A review of the recent literature concerning the assimilation and utilisation of nitrate and ammonium nitrogen within plants has been presented. Barley plants (Hordeum vulgare L.cv. Clipper) were grown hydroponically under controlled environmental conditions. The aerated nutrient solutions contained 2mM inorganic ¹⁴N supplied as either nitrate alone, ammonium alone, a 1:1 nitrate plus ammonium mixture or a 3:1 nitrate plus ammonium mixture. After 20 days of growth ¹⁵N nutrient solutions were substituted. The plant material was harvested four and eight hours after the commencement of the ¹⁵N feeding experiment and prepared for analysis. Xylem sap was also collected for a period of one hour beginning half an hour before each harvest and continuing for half an hour after harvesting. Separate batches of plants were used for harvesting and sap collection. In nitrate-fed plants the shoot was shown to be the main organ of nitrate assimilation. Xylem sap analysis indicated that 66% of the ¹⁵N supply to the shoot was in the form of nitrate and the majority of the absorbed and assimilated ¹⁵N was located in this region. In ammonium-fed plants, however, ¹⁵N-ammonium accumulated in the root with only a very small amount detectable in the xylem sap. Some 93% of the ¹⁵N exported from root to shoot in the xylem stream was in the form of organic nitrogen (mainly glutamine). This indicated that the root was the major organ of ammonium assimilation and that the shoot was the main destination of root assimilated nitrogen.

Abstract:
L’activité de croissance des plantes se trouve souvent limitée par les conditions contraignantes de l’environnement. La salinité du sol est l’une des majeures contraintes abiotiques qui ne cesse d’envahir les surfaces cultivés chaque année. Elle entraine chez les espèces glycophytes des perturbations d’ordre osmotique, nutritionnel et métaboliques. La nutrition et le métabolisme de l’azote minéral constituent des étapes primordiales dans la synthèse des acides aminés et des composés azotés indispensables chez les plantes. Par conséquent, l’étude de l’expression des enzymes impliquées dans l’assimilation d’azote telle que l’asparagine synthétase (AS, EC 6.3.5.4) chez l’arabette des dames (Arabidopsis thaliana) permet d’avancer nos connaissances sur la régulation transcriptionnelle du métabolisme azoté sous stress salin. Au cours des travaux de recherche entamés dans le cadre de cette thèse, un intérêt particulier est accordé au gène ASN2 chez Arabidopsis. Les résultats obtenus ont montré que la mutation ASN2 a accentué les effets du NaCl sur l’assimilation de l’ammonium. Le mutant asn2-1 se montre plus sensible au stress salin que le sauvage malgré que l’absence des transcrits du gène ASN2 est associé à une expression importante du gène ASN1. L’inhibition de l’activité glutamine synthétase (GS, EC 6.3.1.2), la faible activité aminatrice de la GDH (NADH-GDH, EC 1.4.1.2) sous stress salin ainsi que l’absence des transcrits ASN2 seraient à l’origine de l’accumulation de l’ammonium chez le mutant asn2-1. Toutefois, l’application exogène de l’ammonium nous a montré que l’action du NaCl sur l’expression de l’asparagine synthétase n’est pas directement liée à l’accumulation endogène d’ammonium. L’accumulation d’autres métabolites tels que l’asparagine, la glutamine et la glutamate pourrait être à l’origine des effets du sel sur l’expression des gènes ASN
Plant growth activity is often limited by constraint environment conditions. Soil salinity is one of major abiotic stress which is becoming more problematic every year. In glycophytes species, it induced osmotic, nutritional and metabolic disturbances. The nitrogen nutrition and metabolism constitute an essential step in amino acid and nitrogen compounds synthesis in plants. Therefore, studying the expression of enzymes involved in nitrogen assimilation such as asparagine synthetase (AS, EC 6.3.5.4) in Arabidopsis thaliana will improve our knowledge on the transcriptional regulation of nitrogen metabolism under salt stress. In the present work of this thesis, a special attention was taken on AS gene (ASN2) wild type and mutants. Obtained results showed that ASN2 mutation accentuated the salt-induced effects on ammonium assimilation. The asn2-1 mutant was more sensitive to salt stress than the wild type, while the ASN2 transcript absence was associated with an important ASN1expression. The observed inhibition of glutamine synthetase (GS, EC 6.3.1.2) activity, the low aminatrice GDH (NADH-GDH, EC 1.4.1.2) activity under salt stress as well as the ASN2 transcript loss brought to an ammonium accumulation in asn2-1mutant. However, exogenous ammonium application showed that NaCl effect on asparagine synthetase expression was not directly related to the endogenous ammonium accumulation. Other metabolites accumulation such as asparagine, glutamine and glutamate could be involved in the obtained salt-effects on ASN expression in Arabidopsis

In this work, tobacco plants with a high proline accumulation due to the insertion of the VaP5CSF129A mutant gene on the control of the promoter constitutive CaMV 35S were used as a model to verify the effect of transgene overexpression on the uptake and utilization of N. The experiment was conducted in a greenhouse for a period of 30 days. The arrangement was completely randomized in the 2x5 factorial scheme, consisting of two genotypes (one transgenic event and one unprocessed control) and five nitrogen fertilization doses (ammonium nitrate (NO3NH4): 25, 50, 100, 200 and 400 kgN ha-¹), totaling 10 treatments with 4 replicates. The plants were evaluated for height, leaf number, dry mass, root/shoot ratio, chlorophyll content, free proline content, nitrogen content, total protein foliar content, carbon/nitrogen ratio and nutritional efficiency for N (Absorption efficiency - EAbs, leaf utilization - EUtil and plant use - EUN). The plants of the transgenic event with high proline accumulation were less efficient than the control plants in terms of nitrogen absorption (lower levels of N in root, leaves and role plant), which resulted in lower EAbs in these plants. For EUtil (given by the relation between leaf dry mass and N content in the plant) there was no difference between the transgenic and control genotypes. However, the transgenic plants presented lower EUN in comparison to the control plants. It was concluded that the use of tobacco plants with overexpression of the VaP5CS129A gene on control of the constitutive promoter CaMV 35S for a high proline accumulation does not present potential of direct use in agricultural systems, since the alteration of the biochemical balance between the metabolisms of nitrogen and carbon did not result in plants with higher EUN.
O aumento da eficiência de uso do nitrogênio (EUN) nas plantas cultivadas é resultado da melhoria da absorção e/ou da utilização do N. Nesse trabalho, plantas de tabaco com alto acúmulo de prolina devido à inserção do gene mutante VaP5CSF129A sobre controle do promotor constitutivo CaMV 35S foram utilizadas como modelo para verificar o efeito da super-expressão do transgene na absorção e utilização de N. O experimento foi conduzido em casa de vegetação por um período de 30 dias. O arranjo foi inteiramente casualizado, no esquema fatorial 2x5, formado por dois genótipos (um evento transgênico e um controle não transformado) e cinco doses de adubação nitrogenada (nitrato de amônio (NO3NH4): 25, 50, 100, 200 e 400 kgN ha-¹), totalizando 10 tratamentos com 4 repetições. As plantas foram avaliadas quanto à altura, número de folhas, massa seca, razão raiz/parte aérea, teor de clorofila, teor de prolina livre, teor de nitrogênio, teor foliar de proteína total e eficiência nutricional quanto ao N (eficiências de absorção - EAbs, utilização na folha - EUtil e uso na planta - EUN). As plantas controle e transgênicas responderam de forma positiva ao incremento de N no solo, tanto em relação às variáveis de crescimento quanto aos parâmetros bioquímicos. As plantas transgênicas apresentaram menor biomassa e maiores teores de compostos nitrogenados nas folhas (na forma de prolina e proteínas) quando comparadas às plantas controle. Quanto à eficiência nutricional, as plantas transgênicas foram menos eficientes que as plantas controle quanto à absorção de nitrogênio (menores teores de N na raiz, nas folhas e na planta); o que resultou portanto em uma menor EAbs nestas plantas. Para a EUtil (dada pela relação entre a massa seca de folhas e o teor de N na planta) não houve diferença entre os genótipos transgênico e controle. Porém, as plantas transgênicas apresentaram menor EUN em comparação às plantas controle. Concluiu-se que o uso de plantas de tabaco com super-expressão do gene VaP5CS129A sobre controle do promotor constitutivo CaMV 35S para um alto acúmulo de prolina não apresenta potencial de utilização direta em sistemas agrícolas, desde que a alteração do equilíbrio bioquímico entre os metabolismos de nitrogênio e do carbono não resultou em plantas com maior EUN.

Abstract:
In order to investigate the effect of the elimination of GOGAT activity in S. cerevisiae, the pool sizes of ammonia, glutamate and glutamine plus the specific activities of the enzymes involved in ammonia assimilation were determined for two genetically engineered strains (AR2 and AR5) and an haploid wild type ( Sigma 1278b). AR2 and AR5 strains carry the plasmid pCYG4 which directs about 5 fold more NADPH-GDH activity than wild type cells. AR5 strain is a double mutant, which lacks GOGAT activity. The studies were carried out using a microprocessor-controlled fermenter (PCS) which has the following features: 3 Main Boards (Central Processor Board, Memory Board and Analog/Digital - ON/OFF Switch Board). 4 Auxiliary Boards (pH, Oxygen, Temperature and Biomass Interface Boards). A connection block to link the PCS with the video terminal, with sensors from the fermenter, with a control box and with other microcomputer. AR2 and AR5 showed lower values of maximum specific growth rates than the wild type, determined either by batch mode or by washout kinetics. The reduction in the growth rate for AR2 and AR5 can be related to the added metabolic loads due to the plasmid encoded genes. Under carbon limitation there were no remarkable differences between the NADPH-GDH activities of AR2 (GOGAT+) and AR5 (GOGAT-). However, the concentrations of glutamate and glutamine for AR2 were higher (from 20 to 40 %) than those of AR5. The lack of the GOGAT activity also resulted in a decrease in the biomass concentration for AR5 compared to the GOGAT+ strains. Under nitrogen limitation NADPH-GDH activities were higher and intracellular ammonia concentrations lower than under carbon limited conditions. The intracellular concentrations of glutamate and glutamine were higher for the GOGAT+ strain than for the GOGAT- one. Although the biomass level was the same for the three strains, AR5 (GOGAT") cells changed from rounded to ellipsoidal form under nitrogen limited conditions. Oscillations were present in the NADPH-GDH activities of AR2 and AR5 strains growing under carbon and nitrogen limited media. They are probably due to segregational instability of the plasmid pCYG4 in these microorganisms.
