ABSTRACT: To get further insights into the potential involvement of proteins in long distance signaling of leaves iron status to the root system, a label free experiment was done to determine the protein phloem sap composition in contrasted iron growth conditions in wild type and knock out Arabidopsis mutant of the master regulator gene URI (i.e., bhlh121).

Iron (Fe) is an essential micronutrient for plant growth and development whose homeostasis must be tightly regulated to avoid deficiency or excess that could be detrimental to the cells. In Arabidopsis thaliana, this mechanism is regulated by a series of transcription factors that act in an intricate regulatory network among which URI/bHLH121 (UPSTREAM REGULATOR OF IRT1) plays a predominant role. Tremendous efforts were deployed to decipher the molecular mechanisms that regulate iron homeostasis ...[more]

Project description:Essential metals such as iron are required for healthy plant growth. Fe is an important cofactor and catalytic element in many biological processes. Fe and other metals can also be toxic when present in excess. Therefore plants have mechanisms of metal homeostasis which involve coordination of metal ion transporters for uptake, translocation and compartmentalisation. The NAS genes are supposed to play an important role in Fe homeostasis. They are coding for enzymes called nicotianaminesynthase (NAS), which synthesize nicotianamine (NA) by a one-step condensation reaction of three molecules S-adenosyl-methionine. NA acts as a chelator for Fe, Cu, Ni and Zn and might be involved in the transport and allocation of Fe throughout the plant. We generated quadruple T-DNA insertion mutant nas plants to investigate NA function as described in Klatte et al., 2009, Plant Physiol. The nas4x-1 plants show an interveinal leaf chlorosis when turning from vegetative to reproductive stage, which intensifies when growing under Fe deficiency conditions. nas4x-1 plants have strongly reduced NA contents and show an elevated Fe deficiency response in roots. By performing microarray experiments we want to reveal global changes on transcriptional level in roots and leaves of nas4x-1 mutant compared to wild type plants grown under Fe supply and Fe deficiency conditions, respectively. The loss of NAS genes has a strong impact on the regulation of other metal homeostasis genes and allows to draw conclusions about nicotianamine function in metal homeostasis of A.thaliana. For this study, four-week old nas4x-1 mutant and wild type plants were exposed for 7 days to plant medium with and without Fe supply. These conditions have been established previously and have resulted in a reproducibly strong interveinal leaf chlorosis of nas4x-1 plants compared to wild type, especially upon Fe deficiency conditions. The experiment was repeated three times in consecutive weeks to obtain three independent biological repetitions. Rosette leaves and roots of five week-old plants were harvested, RNA was isolated and microarray hybridization was performed. 24 Total samples were analyzed. We generated the following pairwise comparisons: WT + Fe vs. – Fe, nas4x-1 + Fe vs. – Fe, + Fe WT vs. + Fe nas4x-1, - Fe WT vs. - Fe nas4x-1, roots and leaves

Project description:The metabolic response of maize source leaves to low nitrogen supply was analyzed in maize seedlings by parallel measurements of transcriptome and metabolome profiling. Inbred lines A188 and B73 were cultivated under controlled growth chamber conditions and supplied with either sufficient (15mM) or limiting (0.15mM) nitrate supply. Leaf lamina material was harvested at day 20 and day 30 after germination with the fifth and sixth leaf representing the main source leaf respectively. Four replicates were collecetd from individual plants for each combination of genotype, growth stage and nitrogen treatment. The leaf material was frozen, homogenised and aliquoted for transcriptome and metabolome analysis. The molecular data was further supplemented by phenotypic characterisation of the maize seedlings under investigation. Limited availability of nitrogen caused strong shifts in the metabolite profile of leaves. The transcriptome was less affected by the nitrogen stress but showed strong genotype and age dependent patterns. Nitrogen starvation initiated the selective down-regulation of processes involved in nitrate reduction and amino acid assimilation; ammonium assimilation related transcripts on the other hand were not influenced. Carbon assimilation related transcripts were characterized by high transcriptional coordination and general down-regulation under low nitrogen conditions. Nitrogen deprivation caused a slight accumulation of starch, but also directed increased amounts of carbohydrates into the cell wall and secondary metabolites. The decrease in N availability also resulted in accumulation of phosphate and by strong down-regulation of genes usually involved in phosphate starvation response, underlining the great importance of phosphate homeostasis control under stress conditions. Maize inbred lines A188 and B73 were cultivated in pots containing nutrient poor peat soil under the controlled conditions of a growth chamber. The plants were fertilized with modified Hoagland solutions containing either 15mM (high N) or 0.15mM nitrate (low N). Source leaf lamina were harvested at day 20 and day 30 after start of germination for parallel analysis of transcriptome and metabolome profiles. The molecular data is further supplemented by phenotypic characterization of the maize seedlings under investigation.
