Phosphorus-mediated alleviation of aluminum toxicity revealed by iTRAQ technique in Citrus grandis roots

ABSTRACT: Citrus grandis seedlings were irrigated with nutrient solutions containing two levels of aluminium (Al; 0 mM and 1.2 mM AlCl3•6H2O) and two levels of phosphorus (P; 0 μM and 200 μM KH2PO4) combinations for 18 weeks, respectively. The proteome profile of Citrus root submitted to different P-Al interactions were investigated by using isobaric tags for relative and absolute quantification (iTRAQ).

Citrus grandis seedlings were irrigated with nutrient solutions with four Al-P combinations [two Al levels (0 mM and 1.2 mM AlCl3·6H2O) × two P levels (0 μM and 200 μM KH2PO4)] for 18 weeks. Al dramatically inhibited the growth of C. grandis seedlings, as revealed by a decreased dry weight of roots and shoots. Elevating P level could ameliorate the Al-induced growth inhibition and organic acid (malate and citrate) secretion in C. grandis. Using a comparative proteomic approach revealed by the is ...[more]

Arabidopsis col and rglg iron deficiency response

Project description:To dissect the mechanisms that control and mediate cellular iron homeostasis, we conducted quantitative high-resolution iTRAQ proteomics and microarray-based transcriptomic profiling of iron-deficient Arabidopsis thaliana plants. Proteomic and transcriptomic profiling of Arabidopsis Col and RING DOMAIN LIGASE1 (RGLG1) and RING DOMAIN LIGASE2 (RGLG2) double mutation in response to iron deficiency were conducted. This integrative analysis provides a detailed catalog of post-transcriptionally regulated proteins and allows the concept of a chiefly transcriptionally regulated iron deficiency response to be revisited.

Systems-wide analysis of manganese deficiency-induced changes in gene activity of Arabidopsis roots

Project description:In this study, we undertook a comprehensive quantitative proteomic profiling of Arabidopsis roots from plants grown on Mn-deplete media, aiming at dissecting and cataloging the responses of Arabidopsis roots to Mn deficiency. We used LC-Q Exactive Orbitrap mass spectrometer to compile a near complete inventory of the Arabidopsis root proteome. We identified several novel components of cellular Mn homeostasis and show that many putatively important changes in response to Mn deficiency are only evident at one of the omics levels under investigation.

Proteomic analysis of proteins related to rice grain chalkiness using iTRAQ based on a notched-belly mutant with white-belly

Project description:Grain chalkiness is a complex trait adversely affecting appearance and milling quality, and therefore has been one of principal targets for rice improvement. Eliminating chalkiness from rice has been a daunting task due to the complex interaction between genotype and environment and the lack of molecular markers. In addition, the molecular mechanisms underlying grain chalkiness formation are still imperfectly understood. We identified a notched-belly mutant (DY1102) with high percentage of white-belly, which only occurs in the bottom part proximal to the embryo. Using this mutant, a novel comparison system that can minimize the effect of genetic background and growing environment was developed. An iTRAQ-based comparative display of the proteins between the bottom chalky part and the upper translucent part of grains of DY1102 was performed. A total of 113 proteins responsible for chalkiness formation was identified. Among them, 70 proteins are up-regulated and 43 down-regulated. Approximately half of these differentially expressed proteins involved in central metabolic or regulatory pathways including carbohydrate metabolism (especially cell wall synthesis) and protein synthesis, folding and degradation, providing proteomic confirmation of the notion that chalkiness formation involves diverse but delicately regulated pathways. Protein metabolism was the most abundant category, accounting for 27.4% of the total differentially expressed proteins. In addition, down regulation of PDIL 2-3 and BiP was detected in the chalky tissue, indicating the important role of protein metabolism in grain chalkiness formation. Using this novel comparison system, our comprehensive survey of endosperm proteomics in the notched-belly mutant provides a valuable proteomic resource for the characterization of pathways contributing to chalkiness formation at molecular and biochemical levels.

Protein expression in tomato tissues as a function of Al3+ stress (Suping_Exp4)

Project description:The goal of this experiment is to identify the changes in protein expression induced by Al treatment with a view towards developing a molecular level understanding of Al tolerance in an important crop species. In this particular experiment the focus was on protein expression in tomato embryo. Tomato (Solanum lycopersicum ‘Micro-Tom’) plants were treated in Magnavaca’s solution (pH 4.5) supplemented with 50 µM AlK(SO4)2·12H2O providing 7.5 µM Al3+ activity over a four-month period beginning at the emergence of the first flower buds and ending when a few leaves started to turn yellow. Proteins from root, leaf, embryo and seed-coat tissues were identified using a 8-plex iTRAQ labeling strategy followed by a two-dimensional (high- and low-pH) chromatographic separation, and final generation of MS/MS spectra of tryptic peptides on an LTQ-Orbitrap Elite-mass spectrometer
