Transcriptomic responses to phosphate limitation in maize lines with different breeding history

ABSTRACT: Plants cope with low phosphorus availability by adjusting growth and metabolism through transcriptomic adaptations. We hypothesize that selected genotypes with distinct P use efficiency covering the breeding history of European heterotic pool allow us to reveal general and genotype-specific molecular responses correlated with low phosphate induced traits.

Exploring the Dynamic Adaptive Responses of Epimedium pubescens to Phosphorus Deficiency Through Combined Transcriptome and miRNA Analysis [RNA-Seq]

Project description:In the early stages (30 days) of phosphorus deficiency stress, Epimedium pubescens leaves cope with short-term phosphorus deficiency by increasing the expression of related genes such as carbon metabolism, flavonoid synthesis and hormone signal transduction pathways, producing sufficient energy, scavenging ROS, and adjusting plant morphology. However, with the extension of stress duration to 90 days, the expression of genes related to phosphorus cycling and phosphorus recovery (PHT1-4, PHO1 homolog3, PAP) was upregulated, and transcriptional changes and post-transcriptional regulation (miRNA regulation and protein modification) were enhanced to resist long-term phosphorus deficiency stress. In addition, bHLH, MYB, NAC, WRKY and other families also play an important role in regulating gene expression and coping with phosphorus deficiency stress, especially MYB60 negatively regulates flavonoid synthesis pathway, which is significantly down-regulated in leaves treated with phosphorus deficiency for 30 days, thereby promoting the accumulation of flavonoid compounds in leaves.

Phosphate limitation intensifies negative effects of ocean acidification on globally important nitrogen fixing cyanobacterium

Project description:The filamentous diazotrophic cyanobacteria Trichodesmium spp. supply fixed nitrogen (N) to the N-depleted oligotrophic oceans where their growth is often limited by the low availability of phosphorus(P) and/or iron. Previous studies have mostly been focused on the effects of ocean acidification on Trichodesmium under nutrient sufficient or iron-limited conditions. Only a few studies have examined the impacts of ocean acidification on Trichodesmium grown at low P concentrations using non-steady-state batch cultures. Here we cultured Trichodesmium using P-limited continuous cultures (chemostat) to mimic steady-state oceanic low P condition, and used comparative NGS-derived Trichodesmium transcriptome profiling (RNA-seq) analysis to find differentially expressed genes and cellular pathways in response to acidification.

Expression signatures of Arabidopsis thaliana roots under low or high phosphate conditions.

Project description:To cope with limiting phosphorus (P) availability, plants have evolved a series of mechanisms to recycle internal P sources and to acquire P from the soil. One of these mechanisms is the release of low-molecular weight carboxylates, such as malate, which helps to liberate phosphate desorbed to aluminum and iron oxides. As malate release into the rhizosphere and root apopplast also increases iron availability. To identity genes involved in this interaction, we investigated time-dependent changes in the transcriptome of Arabidopsis thaliana roots exposed to sufficient and deficient phoshate levels .

Expression data of soybean accessions under different phosphorus treatments

Project description:Phosphorus is one of the most important macronutrients that is required for plant growth and development. However, stress under low-P conditions has become a limiting factor that affects crop yields and qualities. Plants have developed strategies to cope with this, while few genes associated with low-P tolerance have been identified in soybean. We used microarrays to detail the global programme of gene expression under different phosphorus treatments of two soybean accessions CD and YH with different phosphorus efficiency. The roots and leaves of a low-P-tolerant accession and a low-P-sensitive accession were harvested after 10 days of hydroponics under different P treatments, each with three biological replicates.Then microarray chips were performed on the 24 samples. We sought to identify genes associated with low-P stress. To that end, we analyzed the differently expressed genes between different P treatments, different accessions and different tissues.

Global gene expression of Ruegeria pomeroyi strain DSS3 in response to glucose, ammonium, phosphate, or sulfate limitation

Project description:We used the previously designed oligonucleotide-based microarray (Burgmann et al. Environmental Microbiology 2007, 9: 2742-2755) to detect the transcripts of R. pomeroyi DSS-3 genes when the cells were cultured under steady-state carbon (glucose), nitrogen (ammonium), phosphorus (phosphate), or sulfur (sulfate) limitation.

Dynamic responses of barley root quantitative succinyl-proteome to short-term phosphate starvation and recovery

Project description:Improving phosphate (Pi) acquisition and utilization efficiency is a crucial challenge for the sustainability of agriculture worldwide. The understanding of plant how to response and cope with Pi-limitation, and its underlying molecular mechanisms is key to discovering strategies of efficient Pi acquisition and utilization. Barley (Hordeum vulgare L.) is one of the major cereal crops, has distinct advantage for studying mechanisms of tolerance of phosphorus deficiency due to low Pi demand. Recent studied reveal that post-translational modification (PTM) by phosphorylation, ubiquitination, and glycosylation are play important roles in cellular regulation the plant phosphate starvation response (PSR). Lysine succinylation occurs frequently in the proteins associated with metabolic pathways, which may participate in the regulation of the plant PSR process. However, succinylation precisely modulates the metabolic pathways of proteins in response to PSR in barley remain largely unknown.
