TranscriptomicsTranscription profiling by array of Arabidopsis seedlings mutant for pif1
Arabidopsis bHLH transcription factor PIF1 has been shown function as a negative regulator of Chlorophyll biosynthesis. Pif1-2 mutant accumulate more protochlorophylide during prolonged dark growth condations, therefore the comparation between Wt and pif1-2 mutant will help us find the PIF1 target g...

TranscriptomicsLack of the pif1 helicase enhances zinc tolerance in S. cerevisiae
The Saccharomyces cerevisiae gene PIF1 encodes a conserved eukaryotic DNA helicase required for both mitochondrial and nuclear DNA integrity. Our previous work revealed that a pif1D strain is tolerant to zinc overload. We demonstrate here that this effect is independent of the Pif1 helicase activity...

TranscriptomicsExpression changes by Endodermal PIF1: SCR:PIF1/pifQ transgenic plant vs. pif1pif3pif4pif5 (pifQ) mutant
Transcriptional profiling of dark-grown Arabidopsis seedlings comparing SCR:PIF1/pifQ transgenic plant with pif1pif3pif4pif5 quadruple mutant (pifQ). Seedlings were grown under dark condition for 2.5 days. Goal was to determine the effects of endodermal PIF1 in dark-grown seedlings. Two-condition ex...

GenomicsGenome-wide identification of PIF1-binding sites and direct-target genes of PIF1 transcriptional regulation in skotomorphogenesis
Dark-grown seedlings exhibit skotomorphogenic development. Genetic and molecular evidence indicates that a quartet of Arabidopsis Phytochrome (phy)-Interacting bHLH Factors (PIF1, 3, 4 and 5) are critically necessary to maintaining this developmental state, and that light activation of phy induces a...

TranscriptomicsRad53-mediated regulation of Rrm3 and Pif1 DNA helicases contributes to prevention of aberrant fork transitions under replication stress.
Replication stress activates the Mec1ATR and Rad53 kinases. Rad53 phosphorylates nuclear pores to counteract gene gating, thus preventing aberrant transitions at forks approaching transcribed genes. Here, we show that Rrm3 and Pif1, DNA helicases assisting fork progression across pausing sites, are ...

TranscriptomicsTranscriptome profiling of pig chromosomes regions associated with water holding capacity [PiF1].
To further characterize genomic regions previously identified which are linked with meat quality traits like drip loss, PH, conductivity and etc., we employed a customary regional tiling array experiment for two pig populations. Total RNA were taken from muscle sample of M. longissimus dorsi of pigs...
