Early Iron Deficiency Induced Changes in Arabidopsis Roots

ABSTRACT: Due to limited bio-availability of Fe, plants evolved adaptive alterations in development regulated at the transcriptional level. We investigated the early transcriptional response to Fe deficiency. A hydroponic system was used that allows bulk transferring of plantsand rapid Fe removal with little mechanical damage to the root systems.

Early iron-deficiency-induced transcriptional changes in Arabidopsis roots as revealed by microarray analyses.

<h4>Background</h4>Iron (Fe) is an essential nutrient in plants and animals, and Fe deficiency results in decreased vitality and performance. Due to limited bio-availability of Fe, plants have evolved sophisticated adaptive alterations in development, biochemistry and metabolism that are mainly regulated at the transcriptional level. We have investigated the early transcriptional response to Fe deficiency in roots of the model plant Arabidopsis, using a hydroponic system that permitted removal o ...[more]

Iron-deficiency-induced changes in wild type, ubc13A and cucumber CsUBC13 overexpressed Arabidopsis thaliana roots

Project description:CsUBC13 was identified via proteomics from iron starvation treated Cucumber root. ubc13A is an ABRC seed stock (CS51269). CS851269 was purchased from ABRC and confirmed as homozygous Atubc13A knock-out T-DNA mutant. We generated transgenic arabidopsis with ectopic expression of CsUBC13 gene under control of the cauliflower 35S promotor. Both genotypes and Col-0 were used to investigate the transcriptional response to Iron (Fe) deficiency. Wild type Col-0, ubc13A and transgenic overexpressor OE were grown under normal and iron-deficiency conditions. Roots were collected with 3 biological replicates.

Iron-deficiency-induced changes in wild type and IRP1overexpressed transgenic Arabidopsis plants

Project description:a novel orphan peptide, IRON-REGULATED PROTEIN1 (IRP1) that is rapidly induced by Fe deficiency and improves growth on Fe-deplete media. In Arabidopsis, ectopic expression of IRP1 affected the activity of several genes involved in Fe acquisition and homeostasis, causing a dramatic increase of Fe in leaves and enhanced seed Fe loading. Heterologous expression of IRP1 in tomato plants resulted in increased Fe levels in fruits. Integration of AtIRP1 into the genome of crop plants may represent a novel strategy for Fe biofortification. wild type Col-0 and transgenic overexpressor IRP1-OE plants were grown under normal conditions or subjected to and iron-starvation for 3 days. Roots and shoots were collected with 3 biological replicates.

Transcription profiling of Arabidopsis wild-type and lwd1lwd2 double mutant to investigate the role of LWD1 and LWD2 in Arabidopsis photoperiod regulation

Project description:Transcriptome analysis has revealed a light-regulated WD (tryptophan and aspartate)-containing protein, LWD1. LWD1 and LWD2 share greater than 90% amino acid sequence homology. The lack of phenotype changes in the lwd1 or lwd2 single mutant implies that the proteins function redundantly. The lwd1lwd2 double mutant, however, has an early flowering phenotype under both long-day (LD) and short-day (SD) conditions. Functional complementation experiment revealed that LWDs are indeed responsible for the defect in photoperiod sensing in lwd1lwd2 double mutant plants. The expression of LWD1 exhibits a diurnal pattern and peaks before dawn. The period length of oscillator (CCA1, LHY, TOC1 and ELF4) and output (CCR2 and CAB2) genes in the lwd1lwd2 double mutant is significantly shorter than that in wild-type Arabidopsis under free running condition. Under entrainment conditions, the expression phase of oscillator (CCA1, LHY, TOC1 and ELF4) and output (GI, FKF1, CDF1, CO and FT) genes shifts ~3 hr forward in the lwd1lwd2 double mutant. Our data indicated that the early flowering phenotype in lwd1lwd2 plants is contributed by the significant phase shift of CO and, therefore, an increased expression of FT before dusk under SD conditions. Our data imply that LWD1/LWD2 proteins function in close proximity to the circadian oscillators for the regulation of photoperiod sensing. Experiment Overall Design: Two biological replicates were performed to examine the differential gene expression between wild-type and lwd1lwd2 double mutant. The plants were grown under 12 h L/ 12 h D for 31 days before harvesting their above ground tissues at ZT5-9.

Transcriptome profiling of LecRKVI.2 over-expressor plants.

Project description:The arabidopsis L-type lectin receptor kinase-VI.2 positively regulates bacterial PAMP-triggered immunity. We used microarrays and performed genome-wide transcriptome analysis of LecRKVI.2 over-expressing plants and identified number of upregulated genes involved against bacterial resistance. Total RNA was isolated from 5-week-old Arabidopsis plants for RNA extraction and hybridisation on Affymetrix microarrays.

Transcription profiling of Arabidopsis roots to investigate early phosphate-deficiency induced signal changes

Project description:A mutant previously isolated from a screen of EMS-mutagenized Arabidopsis lines, per1, showed normal root hair development under control conditions but displayed an inhibited root hair elongation phenotype upon Pi deficiency. Additionally, the per1 mutant exhibited a pleiotropic phenotype under control conditions, resembling Pi-deficient plants in several aspects. Under Pi deficiency, the accumulation of Pi and iron was increased in the mutant when compared to the wild-type. Inhibition of root hair elongation upon growth on low Pi media was reverted by treatment with the Pi analog phosphite, suggesting that the mutant phenotype is not the result of a defect in Pi sensing. Reciprocal grafting experiments revealed that the mutant rootstock is sufficient to cause the phenotype. Transcriptional profiling of per1 and wild-type plants subjected to short-term Pi starvation revealed genes that may be important for the signaling of Pi deficiency. We conclude that UBP14 function is crucial for adapting root development to the prevailing local availability of phosphate. Experiment Overall Design: Col-0 and per1 mutant plants were grown under control conditions or subjected to phosphate starvation for 10 h

Expression file from FGF-10 experiment

Project description:Differentiating embryonic stem cells into cardiomyocytes is inefficient, and we discover that FGF-10 can induce embryonic stem cells differentiation into cardiomyocytes. We use microarray to gain insight into the global gene expression and elucidate the machenism that FGF-10 induces embryonic stem cells differentiation into cardiomyocytes. Two-day embryoid bodies were treated with or without 100 ng/ml FGF10 and RNA was obtained 24 hours later and hybridized by Affymetrix microarray

Tracing pluripotency of human early embryos and embryonic stem cells by single cell RNA-seq

Project description:Find the casual relationship between gene expression network and cellular phenotype at single cell resolution. We collected donated human pre-implatation embryos, and the embryonic stem cells derived from them, isolate individual cells, prepared single cell cDNAs, and sequenced them by HiSeq2000. Then we analyzed the expression of known RefSeq genes. We get transcriptome of 124 individual cells from human pre-implantation embryos and human embryonic stem cells by applying single cell RNA-seq technique we recently developed[1][2][3][4]. We did in-depth bioinformatic analysis to these data and found very dynamic expression of protein-coding genes. [1] Tang, F. et al.
