Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1); on Col-0 (Col-0/Col-0). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the total RNA sequencing.

Project description:Nitric oxide regulates plant development and responses to stress. However, the mechanisms underlying its regulatory role are still poorly known, and the impact of endogenous NO on the genome-wide transcriptome of plants has not been studied. For that purpose, we compared the transcriptomes of NO-deficient nia1nia2, noa1-2 and nia1nia2noa1-2 mutant versus wild type Arabidopsis thaliana plants. A core comprising 66 NO-responsive genes with similar expression in all NO-deficient genotypes was identified. Among them, 46 were down- and 20 up-regulated in NO-deficient plants, and thus positively and negatively regulated by endogenous NO, respectively. Accordingly with changes in its transcriptome, the NO-deficient nia1nia2noa1-2 mutant accumulated anthocyanins and indolic glucosinolates, displayed abnormal iron homeostasis in shoots and roots, and also showed altered root sensitivity to hormones such as ABA, ET, CYK and IAA. Together the presented data suggest NO functions essentially as a modulator of hormone action. Compared analysis of the transcriptomes of 15-day old seedlings from 3 different nitric oxide (NO)-deficient mutant genotypes versus wild type background Col-0 (3 independent biological replicates per genotype). NO-deficient mutant seedlings in Col-0 background were the double nia1nia2 mutant in nitrate reductases (NR/NIA) 1 and 2 (abbreviated as nia); the noa1-2 mutant allele in Nitric Oxide Associated 1 (AtNOA1) (abbreviated as noa); and, the triple nia1nia2noa1-2 (abreviated as nino).

Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1); on Col-0 (Col-0/Col-0). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the bisulfite sequencing (methylome). Tissue from the msh1 mutant and dcl2,3,4,msh1 quadruple mutants used as rootstocks was similarly collected at the bolting stage and used for the bisulfite sequencing.

Project description:To investigate the deposition of HTR5 in Arabidopsis, we analysed genome-wide HTR5 density in the wild-type Col-0 by ChIP-seq. We then performed HTR5 occupancy analysis using data obtained from ChIP-seq of 3 different plants including HA-HTR5/Col-0 and Col-0. Col-0 acted as negative control.

Project description:To dissect the mechanisms that control and mediate cellular iron homeostasis, we conducted quantitative high-resolution iTRAQ proteomics and microarray-based transcriptomic profiling of iron-deficient Arabidopsis thaliana plants. Proteomic and transcriptomic profiling of Arabidopsis Col and RING DOMAIN LIGASE1 (RGLG1) and RING DOMAIN LIGASE2 (RGLG2) double mutation in response to iron deficiency were conducted. This integrative analysis provides a detailed catalog of post-transcriptionally regulated proteins and allows the concept of a chiefly transcriptionally regulated iron deficiency response to be revisited.

Project description:Mouse Iron Distribution Dynamics
Dynamic model of iron distribution in mice. This model attempts to fit the radioiron tracer data from Lopes et al. 2010 for mice fed iron deficient and rich diets by adjusting the rate of iron intake (vDiet) and the hepcidin synthesis rate (vhepcidin) independently for each experiment. All other parameters are those that provide the best fit for the adequate diet.
This model includes the radioiron tracer species.

Project description:Many Arabidopsis thaliana accession show sensitvity to the air pollutant ozone, including the accession Cvi-0 from the Cape Verde Islands. To understand and assist in genetic mapping of loci causing the ozone sensitvity of Cvi-0, transcript profiling was performed in Cvi-0, the tolerant Col-0, and a near isogenic line (Col-S) where ozone sensitivity was introgressesed from Cvi-0 to Col-0 through eight rounds of backcrossing.

Project description:ER bodies are endoplasmic reticulum (ER)-derived organelles that might be involved in defense systems. The NAI1 gene regulates the development of ER bodies because mutation of NAI1 abolishes the formation of ER bodies. The nai1-1 mutant had a single nucleotide change at an intron acceptor site of At2g22770 (NAI1 gene). Because of this mutation, aberrant splicing of NAI1 mRNA occurs in the nai1-1 mutant. NAI1 encodes a transcription factor that has a basic-helix-loop-helix (bHLH) domain. Transient expression of NAI1 induced ER bodies in the nai1-1 mutant. To identify genes that are related to ER bodies, we compared the genome-wide expression profiles of Col-0 and the nai1-1 mutant using DNA microarrays. Twenty-nine genes were found to be expressed at least 2-fold more strongly in the nai1-1 mutant than in Col-0, and 341 genes were found to be expressed at least 2-fold more strongly in Col-0 than in the nai1-1 mutant. The 15 genes that showed the strongest expression in Col-0 compared to the expression in nai1-1 are shown in Table 1. Five of these genes are JAL genes (JAL22, JAL23, JAL31, JAL33 and PBP1/JAL30). The mRNA level of PYK10 was reduced in nai1-1 (4.3 fold larger in Col-0 than in nai1-1). The mRNA levels of GLL genes (GLL23 and GLL25) were also reduced in nai1-1. Keywords: mutant vs wt comparison
