Transcriptomic study of soybean (Glycine max) leaves in response to short-term phosphorus deficiency

ABSTRACT: We conducted a genome-wide transcriptomic analysis in soybean leaves treated with a short-term (24 h) Pi-deficiency using RNA sequencing (RNA-seq) technology. Two biological replicates of RNA-seq were included for both Pi-sufficient leaves (PSL) and Pi-deficient leaves (PDL), and therefore a total of four libraries were constructed. Using a 2-fold change and a P-value ≤0.05 as the cut-off for selecting the differentially expressed transcripts, we globally identified short-term Pi-stress responsive genes. Some DEGs potentially involved in Pi sensing, signaling, and homeostasis were up-regulated by Pi deprivation, including five SPX-containing genes. Some DEGs possibly associated with water and nutrient uptake, hormonal and calcium signaling, protein phosphorylation and dephosphorylation, and cell wall modification were affected at the early stage of Pi deprivation. At least thirty-one transcription factor genes belonging to 10 diverse families were found to be responsive to Pi starvation.

Oryza sativa cultivar:Nipponbare Transcriptome or Gene expression

Project description:A comprehensive time-course experiment of Pi-starved plants was undertaken, spanning medium (3 and 7 days), and long-term (21 days up to 52 days) Pi deprivation (âPi), as well as both short term (1 and 3 days) and long-term (31 days) recovery. The 52 days time point consisting of 21 days starvation +31 days recovery enabled investigation of the effects of long term resupply on Pi starved plants, and coincided with the emergence of the first panicles and grains. Pre-germinated rice seedlings were grown for 14 days in Pi sufficient conditions (0.32 mM Pi) before being transferred to either Pi sufficient (0.32 mM Pi) or Pi deficient (0 mM Pi) media for 21 days. After 21 days of Pi deficient treatment, half of the plants were either maintained under Pi deficient conditions or re-supplied with Pi (0.32 mM) for 1, 3 or 31 days. To confirm the effectiveness of the Pi starvation and resupply treatments, physiological and molecular analyses were performed.

Identification of plant vacuolar transporters mediating phosphate storage

Project description:Plant vacuoles serve as the primary intracellular compartments for inorganic phosphate (Pi) storage. Passage of Pi across vacuolar membranes plays a critical role in buffering the cytoplasmic Pi level against fluctuations of external Pi and metabolic activities. Here we demonstrate that the SPX-MFS proteins, designated as Phosphate Transporter 5 family (PHT5), also named Vacuolar Phosphate Transporter (VPT), function as vacuolar Pi transporters. Based on 31P-magnetic resonance spectroscopy analysis, Arabidopsis pht5;1 loss-of-function mutants accumulate less Pi and exhibit a lower vacuolar-to-cytoplasmic Pi ratio than controls. Conversely, overexpression of PHT5 leads to massive Pi sequestration into vacuoles and altered regulation of Pi starvation-responsive genes. Furthermore, we show that heterologous expression of OsSPX-MFS1, the rice PHT5 homolog, mediates Pi influx to yeast vacuoles. Our findings uncover a group of Pi transporters in vacuolar membranes that regulate the cytoplasmic Pi homeostasis required for the fitness of plant growth.

Whole Genome Bisulfite sequencing of Arabidopsis thaliana High and Low phosphate methylomes

Project description:Pi availability is a significant limiting factor for plant growth in both natural and agricultural systems. To cope with such limiting conditions, plants have adapted developmental and biochemical strategies to enhance Pi acquisition and to avoid starvation. A myriad of genes that are involved in the regulation and display of these strategies have been identified. However, the possible epigenetic components regulating the phosphate starvation responses have not been thoroughly investigated. DNA methylation is a major epigenetic mark involved in diverse biological processes and it may play a critical role in Pi starvation stress adaptation, also changes in DNA methylation can lead to a unique gene expression pattern in response to specific developmental and environmental conditions. Here in we demonstrate that non-CpG DNA methylation is required for proper expression of a number of Pi-limitation responsive genes in Arabidopsis thaliana and results in altered morphologic and physiologic phosphate starvation responses.Our data suggest that DNA methylation is involved in the modulation of Pi starvation responses via the transcriptional regulation of a set of phosphate-starvation responsive genes.

Transcription profiling of Arabidopsis leaves, roots and whole plants grown in high or low phosphate conditions for different lengths of time

Project description:The effects of phosphate starvation in Arabidopsis thaliana (L.) plants were compared in plants grown in liquid MS medium transferred in low or high Pi and in plants grown vertically in petri dishes during 10 days. In the transfer experiments, 2 treatments were analysed for evaluating the short-(3, 6 and 12 h pooled) and medium-(1 and 2 d pooled) term effects of Pi deficiency on the gene expression. Since some Arabidopsis genes are regulated by diurnal rhythm and circadian clocks, plantlets were harvested separately at the beginning and at the end of the photoperiod and pooled. In the long term experiment, leaves and roots were sampled separately after 10 days. Triplicates were analysed for each experiment.

Genome wide transcriptomic analysis reveals the mechanism underlying Stylosanthes roots in response to phosphorus deficiency

Project description:Phosphorus (P) is an important macronutrient for plant growth that participates in a series of biological processes. Thus, P deficiency is considered as one of the major constraints limiting crop growth and yield. Although stylo (Stylosanthes) is a dominate tropical legume that displays adaptation to low phosphate (Pi) availability in acid soils, its adaptive mechanisms remain largely unknown. In this study, variation in low P stress tolerance was investigated using two stylo cultivars in hydroponics, which revealed that the stylo RY2 cultivar exhibited higher adaptability to Pi starvation than the RY5 cultivar, as reflected by less reduction in dry weight under P deficient condition, and accompanied by higher P concentrations in shoot and root. Furthermore, better root growth performance and higher APase activity were found in leaves and roots of stylo RY2 cultivar compared to RY5. RNA‐seq analysis revealed 8,348 genes that exhibited differentially expressed under P deficient and sufficient conditions in RY2 roots, with many Pi starvation up-regulated genes associated with P metabolic process, protein modification process, transport and other metabolic processes. A group of differentially expressed genes (DEGs) involved in Pi uptake and homeostasis were identified, such as genes encoding Pi transporter (PT), purple acid phosphatase (PAP), multidrug and toxin extrusion (MATE) and aluminum-activated malate transporter (ALMT). Furthermore, a variety of genes related to transcription factors (TFs) and regulators involved in Pi signaling, including genes belonging to the PHOSPHATE STARVATION RESPONSE 1-like (PHR1), WRKY family, the SYG1/PHO81/XPR1 (SPX) domain, bHLH and ARP family, were also regulated by P deficiency in stylo roots. Taken together, this study suggests a complex adaptive response of stylo to P deficiency, contributing to maintain Pi homeostasis.

Proteomics identifies ubiquitin-proteasome targets and new roles for chromatin-remodelling in the Arabidopsis response to phosphate starvation

Project description:In order to identify new regulators of the phosphate (Pi) starvation signaling pathway in plants, we analyzed variation in the abundance of nuclear-enriched nuclear proteins isolated from Arabidopsis roots that depends on Pi supply. We used 2-D Fluorescence Difference Gel Electrophoresis and MALDI-TOF/TOF techniques for nuclear proteome separation, visualization and relative protein abundance quantification and identification. Pi-controlled proteins identified in our analysis included components of the chromatin remodeling, DNA replication, and mRNA splicing machineries. In addition, by combining Pi starvation conditions with proteasome inhibitor treatments, we characterized the role of the ubiquitin- (Ub)-proteasome system (UPS), a major mechanism for targeted protein degradation in eukaryotes, in the control of the stability of Pi-responsive proteins. Among Pi-responsive proteins, the histone chaperone NAP1;2 was selected for further characterization, and was shown to display differential nucleo-cytoplasmic accumulation in response to Pi deprivation. We also found that mutants affecting three members of the NAP1 family accumulate lower Pi levels and display reduced expression of Pi starvation-inducible genes, reflecting a regulatory role for these chromatin-remodelling proteins in Pi homeostasis.
