Pełny tekst źródłaBridges between nucleic acids sequences and proteins, ribosomes are central components and the “auletes” of living cells. Composed of ribosomal proteins and RNA, they move during their biogenesis from the nucleolus to the cytoplasm, where they translate RNA messengers into proteins. In the past years, some mutants of ribosomal-biogenesis-related proteins have shown the importance of these proteins during cell division and Arabidopsis development. The impact of ribosomal defects on development could be explained by dose effect (which could be important for cell fitness), specificity of ribosomes for some mRNA or multifunctional ribosomal proteins (Mary E. Byrne, 2009). Here I present our work on REBELOTE (RBL), one of the two Arabidopsis homologs of the yeast NOC2 protein, which act during the ribosomal 60S subunit biogenesis. Mutations in REBELOTE gene cause a range of phenotypes, from embryo lethality to growth defects (reduced plant size, altered leaf shape…). To have a better understanding of RBL-controlled processes, we first analyzed the ribosomal function of RBL, and searched for its protein partners. Our results shows that RBL act in two different nucleolar complexes supposed to regulate 60S ribosomal subunit biogenesis. Subsequently, we focused on the effects of rbl mutations on the cell division/elongation processes. Our work shows that defects observed at molecular and cellular levels could explain the slow down of cell divisions and growth delay in rbl mutants

Pełny tekst źródłaNH4+ has not to be reduced prior to assimilation and thus requires less energy for assimilation (Bloom et al., 1992). Apart from high uptake rates in roots, high intracellular ammonium concentrations also result from quantitatively important internal breakdown of amino acids (Feng et al., 1998), and originates in high quantities during photorespiration (Mattson et al., 1997, Pearson et al., 1998). Thus, NH4+ is a key component of nitrogen metabolism for all plants and can accumulate to varying concentrations in all compartments of the cell, including the cytosol, the vacuole and in the apoplast (Wells and Miller, 2000; Nielsen and Schjoerring, 1998). Two related families of ammonium transporters (AMT1 and AMT2), containing six genes which encode transporter proteins that are specific for ammonium had been identified prior to this thesis and some genes had partially been characterised in Arabidopsis (Gazzarrini et al., 1999; Sohlenkamp et al. 2002; Kaiser et al., 2002). However, these studies were not sufficient to assign physiological functions to the individual transporters and AMT1.4 and AMT1.5 had not been studied prior to this thesis. Given this background, it was considered desirable to acquire a deeper knowledge of the physiological functions of the six Arabidopsis ammonium transporters. To this end, tissue specific expression profiles of the individual wildtype AtAMT genes were performed by quantitative real time PCR (qRT-PCR) and promoter-GUS expression. Modern approaches such as the use of T-DNA insertional mutants and RNAi hairpin constructs were employed to reduce the expression levels of AMT genes. Transcript levels were determined, and physiological, biochemical and developmental analysis such as growth tests on different media and 14C-MA and NH4+ uptake studies with the isolated insertional mutants and RNAi lines were performed to deepen the knowledge of the individual functions of the six AMTs in Arabidopsis. In addition, double mutants of the insertional mutants were created to investigate the extent in which homologous genes could compensate for lost transporter functions. The results described in this thesis show that the six AtAMT genes display a high degree of specifity in their tissue specific expression and are likely to play complementary roles in ammonium uptake into roots, in shoots, and in flowers. AtAMT1.1 is likely to be a ‘work horse’ for cellular ammonium transport and reassimilation. A major role is probably the recapture of photorespiratory NH3/NH4+ escaping from the cytosol. In roots, it is likely to transport NH4+ from the apoplast into cortical cells. AtAMT1.3 and AtAMT1.5 appear to be specialised in the acquisition of external NH4+ from the soil. Furthermore, AtAMT1.5 plays an additional role in the reassimilation of NH3/NH4+ released during the breakdown of storage proteins in the cotyledons of germinating seedlings. It was difficult to distinguish a specialisation between the transporters AtAMt1.2 and AtAMt1.1, however the root and flower specific expression patterns are different and indicate alternative functions of both. AtAMT1.4 has a very distinct expression which is restricted to the vascular bundels of leaves and to pollen only, where it is likely to be involved in the loading of NH4+ into the cells.The AtAMT2.1 expression pattern is confined to vascular bundels and meristematic active tissues in leaves where ammonium concentrations can reach very high levels. Additionally, the Vmax of AtAMT2 increases with increasing external pH, contrasting to AtAMT1.1. Thus, AtAMT2.1 it might be specialised in ammonium transport in ammonium rich environments, where the functions of other transporters are limited, enabling cells to take up NH4+ over a wide range of concentrations. The root hair expression ascribes an additional role in NH3/NH4+ acquisition where it possibly serves as a transporter that is able to acquire ammonium from basic soils where other transporters become less effective.RNAi lines showing a reduction in AtAMT gene mRNA levels and NH4+ transport kinetics, grew slower and flowering time was delayed. This indicates that NH4+ is a crucial and limiting factor for plant growth.
Ammonium stellt die von Pflanzen bevorzugte Aufnahmeform anorganischen Stickstoffes dar. Neben dem natürlichen Vorkommen im Boden, wird Ammonium während des Aminosäurestoffwechsels und der Photorespiration innerhalb des Pflanzenkörpers freigesetzt. Um Ammonium aus diesen Quellen zu assimlieren und zwischen den einzelnen Zellen zu transportieren hat die dikotyle Samenpflanze Arabidosis thaliana sechs veschiedene Ammoniumtransporter (AMT) evolviert. Zur Charakterisierung der spezifischen Funktionen der AMts wurden Expressionsprofile der jeweiligen Gene innerhalb der Wurzeln, des Sprosses und der Blüten unter verschiedenen Nährstoffbedingungen mittels quantitativer real-time PCR (qRT-PCT) und Promotor-GUS Expression erstellt. Weiter wurde die Fähigkeit zur spezifischen Regulation der einzelnen Transportergene in Abhängikeit des Stickstoffbedarfes der Pflanze analysiert. Zur Reduktion der mRNA Level der AMTs wurden RNA-Interferenz (RNAi) Mutanten erzeugt und um den Effekt des Verlustes einzelner AMTs zu studieren wurden T-DNA Insertionsmutanten dieser Gene isoliert. Von den mutanten Linien wurden die Transkriptionsraten durch qRT-PCR bestimmt und die NH4+ Transportleistungen durch 14C-Methylammonium (14C-MA) und Ammonium-Aufnahme Experimente analysiert. Weiter wurden Wachstumsanalysen der Mutanten auf verschiedenen Nährmedien durchgeführt und ihre vegetative und generative Entwicklung charakterisiert. Von den isolierten T-DNA Insertionsmutanten wurden Doppelmutanten aller Kombinationen hergestellt und phänotypisch analysiert.Es zeigte sich, daß der an der Plasmamembran lokalisierte AtAMT1.1 in allen Organen in hohen Konzentrationen exprimiert wird und unter Stickstoffmangelbedingungen vermehrt gebildet wird. Vermutlich dient er der generellen Assimilation von internen Ammonium und dessen Transport vom Apoplasten in den Symplasten. AtAMT1.3 und AtAMT1.5 sind in den Wurzeln und hier besonders in den epidermalen Wurzelhaaren exprimiert, die unter anderem der Aufnahme externer Nährsalze dienen. Beide unterliegen starker Regulation durch den internen Stickstoffbedarf der Pflanze. Es ist zu vermuten, daß sie primär der Aufnahme von Ammonium aus dem Boden dienen. AtAMT1.2 wird überwiegend an den vaskulären Geweben und den Blattparenchymzellen exprimiert. Überlappende Expressionsmuster mit AtAMT1.1 machen es schwierig eine spezifische Funktion zu identifizieren. AtAMT1.4 wird ausschließlich im männlichen Gametophyten exprimiert und dient hier vermutlich der Versorgung des Pollen mit Nährsalzen. AtAMT2 wird u.a. in den Wurzelhaaren exprimiert. Seine steigende Affinität zu Ammonium in basischem Milieu, umgekehrt zu AtAMT1.1, läßt vermuten, daß er der Pflanze die Ammoniumaufnahme bei steigendem pH ermöglicht. Im oberirdischen Sproß ist er überwiegend in Meristemen aktiv. Die in der Ammoniumaufnahme beeinträchtigten RNAi-Linien zeigten langsames Wachstum und blühten später als der Wildtyp. Es sind die ersten beschriebenen Ammoniumtransportermutanten, die einen solchen Phänotyp zeigen.

Pełny tekst źródłaAll organisms require for their survival essential metals. For each required metal exists an optimal concentration between metal deficiency and -toxicity. It has become evident that all organisms developed a complex network of proteins and low molecular compounds to maintain the equilibrium between all metals. Only few molecular components of this metal-homeostasis network are characterized in detail: A number of protein families whose members transport metals over the barrier of lipid-membranes have been identified during the last couple of years. One of those metal-transport families is the Cation Diffusion Facilitator (CDF) family. All characterized members export metals from the cytoplasm – either into cellular compartments or outside the cell. From the 12 Arabidopsis thaliana (A.thaliana) members – Metal Tolerance Protein (MTP)-1 to 1-2 – only MTP1 and MTP3 have been characterized yet. In this work, characterization of MTP2 is described. As was found for the homologous proteins AtMTP1 and AtMTP3, heterologous expression of AtMTP2 in Zn-sensitive yeast mutants leads to enhanced Zn-tolerance. Less pronounced, enhanced tolerance was also found for Co when AtMTP2 was expressed in Co sensitive yeast mutants. Expression of chimeric AtMTP2/GFP fusion proteins in yeast, A.thaliana protoplasts and in stably transformed A.thalinana plant lines indicated localization of MTP2 in membranes of the endoplasmic reticulum, when GFP was fused to the C-terminal end of MTP2. Fusion of GFP to the N-terminal end of MTP2 lead to vacuolar localization that is most likely explained as mistargeting due to masking of an ER retrieval motive (XXRR) found at the N-terminus of MTP2. This suggests that AtMTP2 mediates the transport of Zn and Co into the endomembrane system of the cell. Tissue specific localization was performed with plant lines expressing the β-Glucuronidase (GUS) reporter protein and with plant lines expressing chimeric fusions of GFP with AtMTP2 under control of the native pMTP2 promoter. Those experiments confirmed Affymetrix Genechip® data suggesting activity of the pMTP2 promoter only under Zn-deficiency. GUS activity was only found under Zn-deficiency in two zone of root tips – the meristematic zone, characterized by isodiamtric cells, and in the beginning differentiation zone, characterized by appearing root hairs. Confocal microscopy with plant lines expressing chimeric MTP2 /GFP fusions demonstrated that expression of AtMTP2 is restricted to epidermal cells. A phenotype for the homozygous mtp2-S3 knockout mutant could not be identified yet. Based on the data obtained as yet
two mode of action of AtMTP2 in planta seam likely: AtMTP2 could be essential for delivery of Zn to the ER under Zn-deficiency. This is supported by the fact, that AtMTP2 is active in young, dividing (and therefore Zn-requiring) zones of the root. The epidermal-restricted expression of AtMTP2 points towards a distribution of Zn in these root zones of Zn within desmotubules. Alternatively, AtMTP2 could have a Zn-detoxifying function under Zn-shock. It is known that in yeast under Zn-deficiency not only the expression of an Zn-uptake transporter is up-regulated, but also the expression of a vacuolar Zn-transporter. It mediates Zn-detoxification of surplus Zn that enters cells upon Zn-resupply before shut down of the Zn uptake system. AtMTP2 could exert this function when soil Zn-availability raises suddenly, for example due to rain after a drought. Different means/methods are perceivable to identify further components of the metal homeostasis network. In this work, a heterologuos screen was performed in yeast to identify interacting proteins for four members of the Arabidopsis CDF-family. Among 11 candidates identified and confirmed in the Split Ubiquitin System (SUS, a Yeast-2-Hybrid variant) is with AtSPL1 an AtMTP1 interaction candidate, which plays putatively a role in Zn,Cu homoestasis. The c” subunit of the vacuolar H+-ATPase AtVHA was found as likely AtMTP3-interaction candidate, as well as AtNPSN13, an protein that plays putatively a role in fusion of vesicles with target-membranes. Another method to identify new metal homeostasis genes is the comparative elemental analysis of natural and mutagenized plant populations. Prerequisite for this approach is the fast and accurate analysis of the elemental composition of plants. An established method for elemental analysis is Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES). The limiting factor for high thoughput is the requirement for laborious wet digest of plant samples before analysis. An alternative mean of sample delivery to the ICP OES is electrothermal vaporization (ETV). For faster, less laborious analysis of plant material, a method based on the established coupling of ETV with ICP OES was developed, which is optimized for plant material and automated as far as possible.

Pełny tekst źródłaIn an attempt to isolate novel factors that modulate root development, we exploited natural genetic variation in the model plant Arabidopsis thaliana. Tissue culture analysis of 44 accessions led to the identification of a line, Uk-1 (Umkirch-1), whose root system differs significantly from average accessions. A short primary root and an increased number of lateral and adventitious roots are typical for the Uk-1 root system, while the average Arabidopsis root system consists of a predominant primary root and few lateral roots. The major locus responsible for the Uk-1 phenotype, BREVIS RADIX (BRX), was successfully isolated by map-based cloning. Quantitative trait locus (QTL) analysis revealed that BRX is responsible for ca. 80% of the variance of the observed primary root length difference as compared to an average control accession.
BRX controls the extent of cell proliferation and elongation in the growth zone of the root tip and is a member of a novel, small family of proteins that contain three distinct and highly conserved domains of unknown function. BRX is a low abundant, nuclear protein, which is expressed in the phloem and the pericycle at the phloem poles. BRX is also expressed in the columella. Since BRX is not expressed in the root meristem, it must affect root growth in a secondary manner, likely by modulating responses to the plant hormone auxin.
Transcriptional profiling in root tissues revealed that BRX does so by maintaining optimal expression of the brassinosteroid biosynthesis gene CPD, and thereby optimal endogenous levels of the plant hormone brassinosteroid. Further analysis identified BRX as a central component of the interdependency of brassinosteroid signaling and auxin signaling.

Pełny tekst źródłaVascular tissues play an important role in plant physiology and development. Vascular tissues consist on xylem and phloem that ensure sap transport and permit to redistribute mineral and metabolites between different organs. Regulation of vascular tissues establishment is highly controlled in space and time. Among genes involved in vascular tissues formation, OCTOPUS (OPS) gene operates early during development to control vascular patterning and to induce phloem differentiation(Bauby et al., 2007; Truernit et al., 2012). OPS belongs to a multigenic family conserved in high plant. However, molecular function of OPS protein remains unclear. A combination of physiological, biochemical, molecular, cytological and genetic approaches allowed to show that OPS gene is a new positive regulator of brassinosteroid (BR) signaling pathway. BR are phytohormones involved in many developmental processes such as cell elongation or vascular tissues organization. Although BR were discovered in 1970 (Mitchell et al., 1970; Mitchell and Gregory, 1972; Grove et al., 1979), interest of researchers for this hormone permitted its detailed description. Among the component of BR signaling, the BIN2 kinase is the key regulator (Li et al., 2001) which represses the pathway through its action on BES1 and BZR1 transcription factors(Yin et al., 2002; Wang et al., 2002). OPS interacts physically with BIN2 at the plasma membrane which could create an inhibition by delocalization of the BIN2 protein from its activity place. As such, opsphloem defects are restored when the activity of BIN2 is inhibited or when the pathway is induced downstream of BIN2. Thus, we show that BR pathway is directly involved in phloem differentiation. More generally, a study of the functional redundancy of other OPS family members suggests that they could have a similar function as positive regulators of BR pathway in other plant tissues

Pełny tekst źródłaAbiotic stresses (extreme temperatures, salinity, drought) impair plant growth and development and are important agronomic challenges. Understanding stress responses developed by various species contributes to crop improvement and also constitutes an interesting approach of integrated mechanisms operating at different organisation levels in highly regulated ways. Availability of genotypes collections, molecular analysis tools and efficient bioinformatics pave the way to phenotyping of model plants at the genomic scale, in relation with their environment. Metabolmics, defined as unbiaised, nontargeted and exhaustive analysis of metabolites in biological samples, provide new insights into physiological processes like nutrition, biochemical and structural adaptation or cell signalling. Present work is an exploratory, diagnostic and correlative approach of primary metablome in the stress sensitive species Arabidopsis thaliana

Pełny tekst źródła134Cs and 137Cs, two radioactive isotopes unintentionally released after the Chernobyl and the Fukushima accidents, are of major concern for ecosystems protection and human health. Plants contamination is due to their ability to absorb cesium from the soil solution via transporters. Indeed, cesium which is supposed to have no role in plants can pass through potassium transporters. Proteins involved in potassium transport are diverse and the part of fluxes covered by each of them depends on the level of potassium supplied to the plant. We tested the effects of this level on uptake and distribution of cesium into the plant. Beside competition between the two elements, transporters which are dominant for a given potassium supply condition modify the cesium transport. Making the link between these modifications and knowledge on identity and properties of potassium transporters, we highlighted candidates with high potential for cesium transport. Hence, results produced during my thesis demonstrate in planta the role of KUP9 transporter, which has received little attention so far, in cesium fluxes in Arabidopsis thaliana. Changing in potassium uptake has not been observed in mutant lines disrupted in this KUP9 transporter suggesting interestingly that it could be possible to modulate cesium uptake without alteration of potassium nutrition
