Project description: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.
Project description:Transcriptional profiling of 60h-old Arabidopsis whole seedlings comparing control Col-0 wild-type plants with pifQ mutant plants The expression profile of dark-grown pifQ mutant shows similar pattern of Rc-grown Col-0 wild-type Keywords: Genetic modification
Project description:Transcriptional profiling of Arabidopsis dark-induced senescence comparing wild type (Col-0) with pif quadruple (pif1/3/4/5) mutant. After synchronized germination, the plants were grown under continuous white light for 7 days and transferred to darkness for 2 days to induce senescence. Goal was to determine the effect of PIFs on transcriptomic regulation during dark-induced senescence.
Project description: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 genes in Chlorophyll biosynthesis pathway at genome wide level under the dark grown conditions. We used microarrays to detail the global gene expression under the regulation of PIF1. Experiment Overall Design: 4 days dark grown Wt and pif1-2 seedlings were collected for isolation RNA. Standard Affymetrix protocal and 25K Affymetrix chip (ATH1) were used for Microarry hybridition.
Project description: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 experiment, SCR:PIF1/pifQ vs. pifQ Biological replicates: 3 pifQ replicates, 3 SCR:PIF1 replicates.

Project description:Transcript profiling analysis of csn3-1, csn4-1 and csn5 (csn5a-2 csn5b) light grown and dark grown mutant seedlings compared to light grown and dark grown wild type using Arabidopsis ATH1 GeneChip array Keywords: mutant analysis, growth condition analysis
Project description:The associated files are mass spec data from 4 separate mixed-bed ion exchange column separations of Arabidopsis thaliana Col-0 seedling native extract. Two fractionations used extract from seedlings grown in light and two fractionations used extract from etiolated seedlings (grown in the dark). All fractions were processed similarly for LC-MS/MS but one light-grown fractionation was analyzed on a different mass spectrometer than the other three sets of ion exchange fractions.
