Senescent root proteome in autophagy mutant under nitrogen deficiency

ABSTRACT: Macro-autophagy (hereafter referred to as autophagy) is a universal mechanism in eukaryotic cells that facilitates the degradation of unwanted cell constituents. Autophagy is induced in plant under nitrate limiting conditions and autophagy-defective plants are hypersensitive to starvations. Shotgun proteomic analyses were performed on root extracts from atg5 and atg7 mutants harvested after flowering time, when nitrogen remobilization is induced in the leaves as in the roots. The aim of analysis was to clarify the roles of autophagy in the roots when nitrogen recycling and remobilization are enhanced. Study was performed on both nitrate sufficient and nitrate limiting conditions.

Transcript analysis of nitrogen response in rice

Project description:Understanding gene expression re-programming in response to limiting nitrogen (N) conditions is crucial for ongoing progress towards the development of crop varieties with improved nitrogen use efficiency. We analyzed expression data obtained from leaves and roots of rice plants adapted to sufficient and limiting nitrate as well as after shifting them to low (reduction) and sufficient (induction) nitrate conditions.

Expression data from low nitrate culture in root in maize

Project description:Nitrate is the major source of nitrogen available for many crop plants and is often the limiting factor for plant growth and agricultural productivity especially for maize. Many studies have been done identifying the transcriptome changes under low nitrate conditions. However, the microRNAs (miRNAs) varied under nitrate limiting conditions in maize has not been reported. MiRNAs play important roles in abiotic stress responses and nutrient deprivation. Root is the organ that plants transport nitrate. we used the microarray systems to perform a genome-wide search to detect miRNAs responding to the chronic and transient nitrate limiting conditions in maize. MicroRNAs (miRNAs) are small, endogenous RNAs that are regulators of gene expression in plants and animals. And, miRNAs have been known for years to be important for phosphate, sulphate and copper deprivation responses in plants. In Arabidopsis, small RNA deep sequencing associated with nitrate response had been analyzed. However, information about the way by which miRNA are regulated by abiotic stresses in general and by low nitrate in particular is unavailable for maize. In this study, we used GeneChip® microarray systems to perform a genome-wide search to detect miRNAs responding to the chronic and transient nitrate limiting conditions in roots in maize.

Transcription profiling of wild type and atNRT2.7 genotype Arabidopsis leaves and roots grown in high or low nitrate conditions

Project description:Does the NRT2.7 participate to the HATS?<br> We would like to understand the function of the AtNRT2.7 in nitrate transport under limiting and non limiting nitrate conditions.<br> Plants were harvested after 32 days for plants under high nitrogen nutrition and 42 days for low nitrogen nutrition. Plants were grown hydroponic condition (short day, 170 uE).

Gene expression biomarkers provide sensitive indicators of in planta nitrogen status in Maize

Project description:We have characterized the transcriptional response in Maize under limiting and sufficient nitrogen conditions, and have identified a set of genes whose expression profiles can quantitatively assess the response of plants to those conditions. Four lines, three timepoints, multiple treatments, and three biological replicates for a total of 90 samples. Genotypes : Four Monsanto proprietary Zea mays lines were used, designated Line1, Line2, Line3 and Line4 N02: (Limiting Nitrogen) grown for 28 days to V6 stage with 2mM ammonium nitrate N20: (Sufficient Nitrogen) grown for 21 days to V6 stage with 20mM ammonium nitrate N02T20: (Limiting Nitrogen Supplemented) grown for 28 days to V6 with 2mM ammonium nitrate followed by application of 20mM ammonium nitrate applied at 8AM (and sampled at 10AM, 11PM on the same day, and 10AM the following day) Sampling Times: Day1@10AM, Day1@11PM. Another sample was taken at Day2@10AM (the following day) for Line4 and for all the Nitrogen Supplemented (N02T20) samples of all lines. Development Stage: V6 stage (21 days for sufficient nitrogen treatment and 28 days for limiting nitrogen treatment. Planting was staggered so all sampling was done on the same days.) Plants were grown in green house. Leaf tissue from 4 plants were combined to form each replicate.

Expression data from Arabidopsis autophagy mutants (atg5 and atg9) and wild type (Col-0)

Project description:Autophagy mutants display early yellowing phenotype and major metabolic changes under both ideal and limiting nitrate supplies. We used Affymetrix microarrays to detail the global programme of gene expression underlying metabolic and cellular changes in autophagy mutants and wild type Arabidopsis rosettes grown under both low or high nitrate conditions. Fold changes data between mutants and wild type have been published (www.plantcell.org/cgi/doi/10.1105/tpc.114.124677)

INTEGRATED MULTI-OMICS ANALYSES OF MAIZE REVEAL ROLES FOR AUTOPHAGIC RECYCLING IN PROTEOME REMODELING AND LIPID TURNOVER

Project description:The turnover of cytoplasmic material via autophagic encapsulation and delivery to vacuoles is essential for recycling cellular constituents, especially under nutrient-limiting conditions. To determine how cells/tissues rely on autophagy, we applied in-depth multi-omic analyses to study maize (Zea mays) autophagy mutants grown under nitrogen-replete and starvation conditions. Surprisingly, broad alterations in the leaf metabolome were evident in plants missing the core autophagy component ATG12 even without stress, particularly affecting products of lipid turnover and secondary metabolites, which were underpinned by substantial changes in the transcriptome and/or proteome. Cross-comparison of mRNA and protein abundances allowed for the identification of organelles, protein complexes, and individual proteins targeted for selective autophagic clearance, and revealed several processes controlled by this catabolism. Collectively, we describe a facile proteomic strategy to survey autophagic substrates, and show that autophagy has a greater than expected influence in sculpting plant proteomes and membranes both before and during nitrogen stress.

Comparison of root transcriptomes in Arabidopsis thaliana plants supplied with different forms of inorganic nitrogen

Project description:Plants aquire nitrogen from the soil, most commonly in the form of either nitrate or ammonium. Unlike ammonium, nitrate must be reduced (with NADH and ferredoxin as electron donors) prior to assimilation. Thus, nitrate nutrition imposes a substantially greater energetic cost than ammonium nutrition. Our goal was to compare the transcriptomes of nitrate-supplied and ammonium-supplied plants, with a particular interest in characterizing the differences in redox metabolism elicited by different forms of inorganic nitrogen. We used microarrays to compare the short-term transcriptional response to either nitrogen supply or ammonium supply in Arabidopsis roots. Genes upregulated or downregulated by nitrate only, ammonium only, or both ammonium and nitrate were identified and analyzed.
