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:The goal of this study is to clarify the function of ARF7 in the pathway of auxin inducing the process responding to gravity in hypocotyl. We isolated total RNA from the hypocotyls of 4-day-old Col-0 and arf7 seedlings that were grown in the darkness. New genes act downstream of ARF7 after responding to auxin treatment, responding to gravity, are discovered.

Project description:We hypothesized a convergence of transcriptome profiles in hypocotyls of low blue light (LB) or low red/far red light (LRFR) treated seedlings as both conditions trigger hypocotyl cell elongation. To test this hypothesis, we did a transcriptome analysis in of 5d-old long-day (LD)-grown Col-0 (wild type, WT), pif457, and yuc2589 seedlings treated for 3 hours with LB, LRFR or remaining in the same light condition (WL). We used dissected cotyledons and hypocotyls to characterize the LB and LRFR response in both organs and determine their dependency on PIFs and YUC-mediated auxin biosynthesis.
Project description:In this Data Report, we provide an immunoprecipitation (IP)-based analysis of the HDA19 interactome in etiolated Arabidopsis seedlings. We believe that the interactome presented here provides a valuable resource for follow-up research on novel interacting partners of this central protein. The material used for this experiment was derived from hypocotyls of 6-day-old etiolated Arabidopsis seedlings. The dataset contains a total of 6 files, 3 independent biological replicates of each Col-0 (control plants) and 35S::HDA19-GFP plants.
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.
Project description:Arabidopsis thaliana (Col-4) aerial tissue collected from 14-day old plants. Grown under sterile conditions at 22 degrees Celsius and 125 uE light on 0.5xMS media.
Project description:We used RNA-Seq to ask whether the transcripts for the proposed BCKDH subunits are upregulated in wild-type plants subjected to prolonged darkness. These experiments were performed using rosette leaves from 5-week-old, short-day-grown (8h light/16h dark) Col-0 wild-type plants moved to constant darkness for 6h, 24h, 48h and 72h, and grown in short day for 72h as control. The transcripts of eight BCAA catabolism genes were increased nine- to 400-fold within the first 6h of prolonged darkness, and remained high until the last time point. These results are consistent with the hypothesis that BCAA catabolic enzymes - including BCKDH subunits E1A1, E1B1, E1B2 and E2 - have one or more physiological roles in the dark.
Project description:Chromatin immunoprecipitation was performed in nlp2-2 Arabidopsis thaliana Col-0 14-d-old seedlings complemented by a pNLP2::NLP2-GFP construct upon 30 minutes NO3- resupply after a 3-day NO3- starvation.
