Proteomics to analyze the growth-promoting effect of a potential new plant growth regulator GZU001 on maize (Zea mays L.) roots

ABSTRACT: Plant growth regulators are the chemical substances that regulate growth and development in plants. The use of plant growth regulators on crops can adjust the balance of hormones and influence plant growth, thereby increasing crop yield and/or improving crop quality. Fubianliusuoyoumi (GZU001), a new potential plant growth regulator, significantly promoted root elongation in maize. However, an underlying potential mechanism is still unknown. To explore the response pathway and regulation mechanism of GZU001 in promoting maize root elongation, a combination of metabolomics and proteomics was used. In total, 101 differentially expressed proteins (DEPs) and 79 differentially expressed metabolites were identified. Our study found that four photosynthetic proteins (COPAQ4, P48183, B4FRH1, and A0A3L6EQ36) were significantly up-regulated, which can promote photosynthesis in maize.

Brassinosteroids application affects maize growth and gravitropic response by regulating gene expression in roots, shoots and leaves

Project description:Brassinosteroids (BRs) are a class of plant-specific steroid hormones which play key roles in plant physiology and seem to actively participate to the regulation of plant responses to stress. For this reason, these compounds are also grouped among the category of plant biostimulants which could be provided to crops to improve their performances and induce abiotic stress tolerance. In this study, thanks to a combined physiological and molecular approach new insight on the effects of 24-epibrassinolide (EBL), a synthetic BR, on hydroponically grown maize seedlings were gained. To this aim, a preliminary assessment of the effect of different EBL concentrations and time of treatment on root elongation was conducted to identify the concentration to be used in subsequent experiments. A treatment with EBL 1nM and a time exposure of 48 hours were then selected to better assess the effects of this molecule also on shoot growth and on root gravitropic response. Afterwards, a RNAseq based untargeted approach was applied to obtain an overview of the transcriptomic regulation occurring in roots, shoot and leaves upon exogenous brassinosteroids applications. Our outcomes highlight a deep influence exerted by this molecule on plant growth and on root gravitropic response of maize seedlings. Moreover, thanks to the functional characterization of differentially regulated genes by means of Gene Ontology (GO) and pathway analyses, new knowledge on the BR response and signalling in plants were gained. Globally, this study provides useful information which could help for future agriculture applications of these categories of substances.

ZmNRT1.1B (ZmNPF6.6) determines nitrogen use efficiency via regulation of nitrate transport and assimilation in maize

Project description:Nitrate (NO3-) is crucial for optimal plant growth and development and often limits crop productivity at the low availability. In comparison with model plant Arabidopsis, the molecular mechanisms underlying NO3- acquisition and utilization remain largely unclear in maize. In particular, only a few genes have been exploited to improve nitrogen use efficiency (NUE). Here, we demonstrated that NO3--inducible ZmNRT1.1B (ZmNPF6.6) positively regulated NO3--dependent growth and NUE in maize. We showed that the tandem duplicated proteoform ZmNRT1.1C is irrelevant to maize seedling growth under nitrate supply, however, loss-of-function of ZmNRT1.1B significantly weakened plant growth under adequate NO3- supply in both hydroponic and field conditions. 15N-labeled NO3- absorption assay indicated that ZmNRT1.1B mediated high-affinity NO3--transport and root-to-shoot NO3- translocation. Furthermore, upon NO3- supply, ZmNRT1.1B promotes cytoplasmic-to-nuclear shuttling of ZmNLP3.1 (ZmNLP8), which co-regulates the expression of genes involved in NO3- response, cytokinin biosynthesis and carbon metabolism. Remarkably, overexpression of ZmNRT1.1B in modern maize hybrids improved grain yield under nitrogen (N) limiting fields. Taken together, our study revealed a crucial role of ZmNRT1.1B in high-affinity NO3- transport and signaling and offers valuable genetic resource for breeding nitrogen use efficient high-yield cultivars.

Transcriptome analysis of rice roots in response to plant growth promoting bacterium Bacillus subtilis RR4

Project description:The aim of our study is to elucidate the gene expression changes in rice in response to colonization by a plant growth promoting rhizobacteria such as the Bacillus subtilis through microarray high throughput technology. In particular, the effect of B.subtilis on root exudation (secretion of phytochemicals through roots) will be analysed. For this rice plantlets were grown in hydroponics and treated with B.subtilis RR4 for 48 hrs. The root samples of the control and treated plants were then used for the microarray experiment. The data obtained through microarray revealed genes related to cell wall modification, phytohormone synthesis, defense response, root exudation, etc. to be differentially regulated in response to B.subtilis RR4. Real time PCR analysis of few chosen genes (OsMS, OsALMT, OsABC, OsSDH, etc) also confirmed the validity of the microarray data. The initial responses of a plant in response to colonization by the microbe will be changes in cell wall of the plant tissues and the secretion of phytochemicals to attract/repel the colonizing beneficial/pathogenic organism. From analysis of microarray data we found the cell wall related genes which aid in root colonization and the root exudate related genes (biosynthesis and transport) which play a role in providing nutrition for the bacterial growth to be differentially regulated significantly. Analysis of specific genes and their biosynthesis pathways indicated that rice plants responded positively to root colonization by B.subtilis RR4. Notable among the exudation related genes such as Malate synthase and ALMT were found to be upregulated which indicates the significant role played by organic acids particularly malate in recruiting the PGPR towards the plant roots. This recruitment will thereby facilitate plant growth. Subsequently, these genes can be engineered in crop plants to recruit beneficial bacteria which might further open new avenues for improved crop production.

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.

Expression data from internodes of maize seedlings

Project description:Plant growth regulators (PGRs) were commonly used in practical farming to restrict plant height and control lodging. Ethephon has been reported to shorten the internodes elongation and increase the harvestable grain yield of maize. In the present study, we characterized that internodes phenotypic responses to ethephon treatment induced should due to ethylene released inhibited the longitudinal growth of cells and promoted its the lateral growth. We used microarrays to detail the global programme of gene differentially expression underlying maize and identified distinct classes of up or down-regulated genes during this process.

Ethylene promotes root hair growth through coordinated EIN3/EIL1 and RHD6/RSL1 activity in Arabidopsis

Project description:Root hairs are an extensive structure of root epidermal cells and are critical for nutrient acquisition, soil anchorage, and environ- mental interactions in sessile plants. The phytohormone ethylene (ET) promotes root hair growth and also mediates the effects of different signals that stimulate hair cell development. However, the molecular basis of ET-induced root hair growth remains poorly understood. Here, we show that ET-activated transcription factor ETHYLENE-INSENSITIVE 3 (EIN3) physically interacts with ROOT HAIR DEFECTIVE 6 (RHD6), a well-documented positive regulator of hair cells, and that the two factors directly coactivate the hair length-determining gene RHD6-LIKE 4 (RSL4) to promote root hair elongation. Transcriptome analysis further revealed the parallel roles of the regulator pairs EIN3/EIL1 (EIN3-LIKE 1) and RHD6/ RSL1 (RHD6-LIKE 1). EIN3/EIL1 and RHD6/RSL1 coordinately en- hance root hair initiation by selectively regulating a subset of core root hair (H) genes. Thus, our work reveals a key transcriptional complex consisting of EIN3/EIL1 and RHD6/RSL1 in the control of root hair initiation and elongation, and provides a molecular framework for the integration of environmental signals and in- trinsic regulators in modulating plant organ development.

An iTRAQ-based proteomics screen analysis of potential regulators of wheat (Triticum aestivum L.) root growth inhibition due to Al stress

Project description:Aluminum (Al)-induced root tip cell elongation inhibition is a major cause of plant root elongation suppression. Root tip cell elongation inhibition is caused by disruption to cell wall component metabolism, growth signaling, or cellular damage. The aim of this study was to identify the proteins involved in root elongation under Al stress in the tolerant wheat (Triticum aestivum L.) ET8. We investigated wheat root protein profiles using isobaric tags for relative and absolute quantification (iTRAQ). In total, 97 differentially expressed proteins from Al-tolerant wheat roots were screened and 11 of the 97 proteins were root elongation related. The 14-3-3 protein, plasma membrane ATPase, phospholipase D, and peroxidase are involved in cell wall component metabolism. The cellulase activity and callase activity were down-regulated by Al stress, whereas, the PAL, CAD, and POD activities were up-regulated. In addition, the callose, cellulose, lignin, and H2O2 contents varied significantly. Furthermore, Al stress inhibited root elongation in a metabolic enzyme and carbohydrate-dependent manner. The results indicated that the protein involved with growth signaling is elongation factor 1-α. The cellular damage related proteins are glycosyltransferase and sucrose 1-fructosyltransferase. The iTRAQ analysis highlighted candidate proteins associated with root cell elongation and revealed several new aspects of the metabolic processes underlying Al toxicity and tolerance. We propose that Al stress leads to marked variations in metabolic enzyme activity, carbohydrate content, and cellular damage, followed by inhibition of root elongation in wheat roots. This study has provided the most integrated view of the adaptive root responses to Al-toxicity.
