Fe-FIT-Diff

Project description:au13-06_fit - Fe-FIT-Diff - FIT (FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR) is a regulator of Fe deficiency responses in the root. FIT is a basic helix-loop-helix protein. Here, we investigated the transcriptome changes in response to Fe deficiency (- Fe) versus the control condition (+ Fe) in wild type, the fit-3 loss of function mutant and in FIT overexpression plants.

Iron uptake in yeast

Project description:Analysis of iron-regulated gene expression in Saccharomyces cerevisiae using cDNA microarrays has identified three putative cell wall proteins that are directly regulated by Aft1p, the major iron-dependent transcription factor in yeast. FIT1, FIT2, and FIT3 (for facilitator of iron transport) were more highly expressed in strains grown in low concentrations of iron and in strains in which AFT1-1(up), a constitutively active allele of AFT1, was expressed. Northern blot analysis confirmed that FIT1, FIT2, and FIT3 mRNA transcript levels were increased 60-230-fold in response to iron deprivation in an Aft1p-dependent manner. Fit1p was localized exclusively to the cell wall by indirect immunofluorescence. Deletion of the FIT genes, individually or in combination, resulted in diminished uptake of iron bound to the siderophores ferrioxamine B and ferrichrome, without diminishing the uptake of ferric iron salts, or the siderophores triacetylfusarinine C and enterobactin. FIT-deletion strains exhibited increased expression of Aft1p target genes as measured by a FET3-lacZ reporter gene or by Arn1p Western blotting, indicating that cells respond to the absence of FIT genes by up-regulating systems of iron uptake. Aft1p activation in FIT-deleted strains occurred when either ferrichrome or ferric salts were used as sources of iron during growth, suggesting that the FIT genes enhance uptake of iron from both sources. Enzymatic digestion of the cell wall resulted in the release of significant amounts of iron from cells, and the relative quantity of iron released was reduced in FIT-deletion strains. Fit1p, Fit2p, and Fit3p may function by increasing the amount of iron associated with the cell wall and periplasmic space.

In vivo dynamics of Iron Starvation Induced Proteins under variable iron supplementation regimes suggest an iron processing organelle in Phaeodactylum tricornutum.

Project description:The model pennate diatom Phaeodactylum tricornutum is able to assimilate a range of iron sources. It therefore provides a platform to study different mechanisms of iron processing concomitantly in the same cell. In this study we follow the localisation of three iron starvation induced proteins (ISIPs) in vivo, driven by their native promoters and tagged by fluorophores in an engineered line of P. tricornutum. In a proteomic analysis, we identify that the cell engages the endocytosis machinery involved in the vesicular trafficking as a response to siderophore molecules, even when these are not bound to iron. We find that the localisation patterns of ISIPs are dynamic and variable depending on the overall iron status of the cell and the source of iron it is exposed to. Notwithstanding, a common destination of the proteins is a globular compartment in the vicinity of the chloroplast, consistent with our proteomic findings, which point to the engagement of the cell’s vesicular network. We propose that this may be a dedicated iron processing site inside the periplastidial compartment of diatoms.

Expression data from Arabidopsis roots and shoots grown with or without iron

Project description:Iron-deficiency repsonses in Arabidopsis are controlled by several bHLH transcription factors. FIT, for example has been shown to direct iron-uptake responses. However, the role of shoot and root expressed genes bHLH100 and bHLH101 has not be clarified. We used microarray to study what genes might be miss-regulated in the double mutant bhlh100/bhlh101 background
