EVALUATION OF THE EFFECTS OF HUMIC ACIDS ON MAIZE ROOT ARCHITECTURE BY LABEL-FREE PROTEOMICS ANALYSIS

ABSTRACT: Humic substances have been widely used as plant growth promoters to improve the yield of agricultural crops. Root soluble protein profiles of 11 days after planting, cultivated with and without humic acids (50 mg C/L), were analysed using the label-free quantitative proteomic approach. The effects on root architecture, such as induction of lateral root and biomass increase were accompanied by changes in the proteins.

Humic substances have been widely used as plant growth promoters to improve the yield of agricultural crops. However, the mechanisms underlying this effect remain unclear. Root soluble protein profiles in plants 11 days after planting and cultivated with and without humic acids (HA, 50 mg CL<sup>-1</sup>), were analyzed using the label-free quantitative proteomic approach. Cultivation of maize with HA resulted in higher fresh weight of roots than in untreated plants (control). Plants treated wit ...[more]

Regulation of gene expression by Candidatus Liberibacter asiaticus in stem and root of Sweet orange (Citrus Sinensis)

Project description:Candidatus Liberibacter asiaticus infection of citrus is characterized by symptom variability within and among organs. In order to identify molecular processes involved in the regulation of organ response to Ca. Liberibacter infection, the gene expression patterns in C. sinensis leaf, stem, and root was examined in Affymetrix microarray. Our analyses showed that Ca. L. asiaticus reprograms several cellular and metabolic processes in C. sinensis, with most categories regulated in leaves, followed by stems and least in roots. Among them, we identified genes whose expression is regulated in organ-specific manner, reflecting organ specialization in the molecular response to Ca. L. asiaticus. Differences in gene expression were expected between these organs because of functional divergence among them. Two-year old Valencia sweet orange (C. sinensis) plants were graft inoculated with budwood from Ca. L. asiaticus-infected citrus plants. Successful infection of the inoculated plants was confirmed in both conventional and quantitative PCR with specific primers to Ca. L. asiaticus. The stem and root samples used for RNA extraction and hybridization on Affymetrix microarrays were obtained from three symptomatic and three healthy control trees of similar size, 16 months after the inoculation.

SopB and SifA modify the proteome of the Salmonella-containing vacuole in the social amoeba Dictyostelium discoideum

Project description:Salmonella enterica serovar Typhimurium is a rod-shaped Gram-negative bacterium. It is a leading cause of gastroenteritis and public health problem. In the environment, it interacts with protozoa, particular amoeba, however the interactions between Salmonella and these eukaryotic microbes have not been addressed in detail. We and others recently described that S. Typhimurium is able to survive in the model amoeba Dictyostelium discoideum requiring the Salmonella pathogenicity islands 1 and 2 (SPI-1 and SPI-2, respectively)-encoded type three secretion systems (T3SSs). In this work, we investigated the role of two particular effector proteins, SopB and SifA that are secreted by either one of the T3SSs. SopB and SifA are involved in the remodelling of the intracellular compartment that contains Salmonella (Salmonella-containing vacuole, SCV) in other cellular models. We combined genetic and proteomics analysis to investigate the roles of SopB and SifA during infections of D. discoideum. We identified over 1,000 proteins per sample performing proteomics on fractions enriched in SCVs from amoeba cells infected with wild-type, sopB or sifA S. Typhimurium. Among them, we observed several Rho GTPases, guanine nucleotide exchange factors and motor proteins. Finally, we decided to evaluate if the changes observed in the proteome from the SCV of wild-type and mutants affect the intracellular survival of S. Typhimurium. These finding suggest that Salmonella exploits this route to survive intracellularly, a process that requires SopB and/or SifA effectors. To our knowledge this is the first proteomic description of the Salmonella intracellular compartment in D. discoideum.

Impact of rhamnolipids (RLs), natural defense elicitors, on shoot and root proteomes of Brassica napus by a Tandem Mass tags (TMTs) labeling approach

Project description:The rapeseed crop (Brassica napus) is valued mainly for animal feed, food oil and biofuel production. This plant is particularly susceptible to many pathogens like parasitic plants, fungi or animals attacking aerial or root parts. Conventional plant protection products, used intensively in agriculture, have a negative impact on the environment (air and water quality, biodiversity, etc.) as well as on human health. There is therefore a growing demand for the development of new, more planet-friendly alternative protection methods such as biocontrol compounds. Natural rhamnolipids (RLs) can be used as elicitors of plant defense mechanisms. Indeed, these glycolipids, from bacteria secretome, are biodegradable, non-toxic and they are known for their stimulating and protective effects, in particular on rapeseed against filamentous fungi. Characterizing the organ responsiveness to defense stimulating compounds like RLs is missing. This analysis is crucial in the frame of optimizing the effectiveness of RLs against various diseases. A TMT labeling of the proteins extracted from the shoots and roots of B. napus has been performed and showed a differential pattern of protein abundance between them. These results have allowed identifying several protein families possibly involved in the differential responses observed in shoots and roots of rapeseed upon RLs treatment. In particular, quantitative proteomic analysis highlighted differential accumulation of parietal and cytoplasmic defense or stress proteins in response to treatments with RLs with a clear effect of the type of application (foliar spraying or root absorption). These results must be considered for further use of RLs to fight specific rapeseed pathogens.

Differentially expressed small RNAs in Arabidopsis galls formed by Meloidogyne javanica

Project description:Root-knot nematodes (RKNs) induce inside the vascular cylinder the giant cells (GCs) imbibed into a gall. Gene-repression in early developing GCs could be facilitated by small RNAs (sRNA) as miRNAs. 24nt-sRNAs, rasiRNAs and 21-22nt-sRNAs can also mediate epigenetic mechanisms. Three sRNA libraries from 3dpi galls and three from uninfected root segments were sequenced following Illumina-Solexa technology. Three sRNA libraries from 3dpi galls and three from uninfected root segments were sequenced

Proteomic Analysis Reveals the Association between the Path-ways of Glutathione and α-Linolenic Acid Metabolism and Lanthanum Accumulation in Tea Plants

Project description:Tieguanyin (TGY) and Shuixian (SX) cultivars of Camellia sinensis were selected to explore the mechanism underlying the accumulation of the rare earth element lanthanum through proteomics. Roots and fresh leaves of TGY and SX with low- and high-accumulation potential for lanthanum, respectively, were studied; 845 differentially expressed proteins (DEPs) were identified. Gene ontology analysis showed that the DEPs are involved in redox processes and related to molecular functions, such as defense and oxidative stress reactions, catalytic activity, and metal ion binding. Kyoto Encyclopedia of Genes and Genomes metabolic pathway analysis showed that DEPs were associated with glutathione (GSH) and α-linolenic acid metabolism, plant pathogen interaction, and oxidative phosphorylation. Thirty-seven proteins in the GSH metabolism pathway showed significant differences, of which 18 GSH S-transferases show differential expression patterns in the root system.The expression multiples of GST (TEA004130.1) and GST (TEA032216.1) in T1L and T0L were 6.84 and 4.06, respectively, which were significantly higher than those in S1L and S0L. The lanthanum-induced activation of the GSH-related antioxidant defense system may cause the difference in TGY and SX. The LOX2.1 (TEA011765.1) and LOX2.1 (TEA011776.1 expression ratios) in the α-linolenic acid metabolic pathway were 2.44 and 6.43 in T1R and T0R, respectively, which were significantly higher than those in S1R snd S0R. The other differential proteins were also sig-nificantly upregulated in TGY leaves.The synthesis of specific substances induces lantha-num-associated defense responses in TGY, which is of great significance for the stability of its yield.

TSAR1 and TSAR2 activate triterpene saponin production in Medicago truncatula

Project description:We identified two novel transcription factors ‘Triterpene Saponin Activation Regulator’ (TSAR) 1 and 2 that each activate a specific branch of saponin synthesis in M. truncatula. Therefore we generated three independent TSAR1 and three independent TSAR2 overexpression (OE) hairy root lines. As a control we raised three independent hairy root lines expressing a non-functional GUS gene. By qRT-PCR analyses and metabolite profiling of these lines, we found that TSAR1 OE leads to accumulation of non-haemolytic saponins whereas TSAR2 instigates accumulation of haemolytic saponins. To identify additional targets of TSAR1 and TSAR2 we carried out a genome-wide transcript profiling study by RNA-Seq.
