ABSTRACT: Immunoprecipitation of 14-3-3 protein using specific antibody against vf14-3-3a from Vicia GCPs treated with or without 10 µM ABA for 10 min in the dark.
Project description:Total RNA was isolated with RNAiso regent (Takara) from 12-day-old seedlings of the areb1 areb2 abf3 triple mutant and WT plants grown on GM agar plates with or without 50 µM ABA for 6 h.
Project description:au08-04_dfo - analysis of deferoxamine treated leaves and roots - What are the effects of the siderophore deferoxamine on Arabidopsis leaves and roots? - Plants were allowed to grow for 5-6 weeks. The nutrient solution contains 0.25 mM Ca(NO3)2.4H2O, 1mM KH2PO4, 0.5 mM KNO3, 1mM MgSO4.7H2O, 50 µM H3BO3, 19 µM MnCl2.4H2O, 10 µM ZnCl2, 1 µM CuSO4.5H2O, 0.02 µM Na2MoO4.2H2O and 50 µM FeNa-EDTA. Plants were subjected to an 8 h light/16 h dark cycle, at 19°C, with 70% relative humidity. Leaves of six week old hydroponically grown A. thaliana Col0 plants were infiltrated with 1mM deferoxamine or sterile distilled water. Leaves were harvested 7 and 24 h.p.i.

Project description:The softened green berries of Cabernet Sauvignon were cultured in a Petri dish. 0.3M sucrose solution with (±)-abscisic acid (ABA) and without (±)-ABA (control) were applied to the Petri dishes. The berry skins were sampled at 3 and 10 days after the application. PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Kazuya Koyama. The equivalent experiment is VV17 at PLEXdb.
Project description:Arabidopsis seed lings were grown in dark for 10 days on MS media and treated with DMSO (control) or 1 µM of BA for either 45 or 120 minutes to look for changes in genes profiles
Project description:Although many regulatory components of light signaling have been functionally characterized, only a few of them have been reported to cross talk with other signaling cascades. In this study, we have analyzed the expression profiles of Arabidopsis genes in wild-type, atmyc2 mutant, cop1-6 mutant, and atmyc2 cop1-6 double mutant seedlings grown under constant dark, constant blue-light, and constant blue-light along with abscisic acid (ABA) to illustrate the interplay of negative regulators, AtMYC2 and COP1, in light and ABA signaling Keywords: Light and abscisic acid treatment Expression data for wild-type, atmyc2, cop1-6, and atmyc2 cop1-6 seedlings under constant dark, blue-light and blue-light along with abscisic acid Ten-day-old Arabidopsis (wild-type, atmyc2 mutant, cop1-6 mutant, and atmyc2 cop1-6 double mutant) seedlings grown under constant dark, constant blue-light (35 µmol/sec/m2), and constant blue-light along with ABA (0.5 µm) were used for RNA extraction and hybridization on Affymetrix microarrays. Two biological replicates of each sample were used for microarray analysis.

Project description:We report differences in the transcriptional responses of the root and the shoot to either auxin or ABA in comparison to mock treatment in dark-grown Arabidopsis thaliana seedlings. By examining the auxin responsiveness in the shoot or the root of a dark-growh ABA biosynthesis mutant, we found that auxin relies on intact ABA biosynthesis in order to regulate aspects of transriptional output.
Project description:4 weeks old rooted plantlets of P. × canescens (Clone INRA717 1-B4) were cultivated in hydroponics in 2 l pots in Long Ashton nutrient solution in a culture room for 8 weeks before treatments started. Three treatments were applied to the plants: control treatment (-ABA), continuous 100 µM ABA treatment (+ABA) and discontinuous 100 µM ABA treatment (±ABA). ABA was fed to +ABA plants during the whole treatment period of 30 days. ABA was fed to ±ABA plants for three days in two weeks. Developing xylem and mature xylem were collected separately during the harvest and shortly frozen in liquid nitrogen. RNA was extracted from these samples and followed by RNA-sequencing.
Project description:Mutations in the heterotrimeric G-protein a-subunit of Arabidopsis, GPA1, leads to deficiency in ABA-induced stomatal closure (Wang et al., 2001). To further investigate whether GPA1 is involved in the regulation of gene expression in response to ABA, we examined the induction of known ABA-inducible genes in the gpa1 mutant and compared it to wild-type. We found significant differences in levels of ABA-induced expression between wild-type and gpa1 mutant. In order to systematically investigate GPA1 involvement in ABA signalling leading to gene expression, we are requesting the transcriptome analysis of the gpa1 mutant in response to ABA.In detail, 2 week old wild-type and gpa1 plants grown in the 16/8 hrs light and dark cycle will be treated with either ABA or with a control solution for 3 hours. 10 plants will be used per sample to produce RNA, to give 4 samples, one for each chip: gpa1-1 mutant in the presence (chip1) or absence of ABA (chip2) and wild-type (WS2) in the presence (chip3) or absence of ABA (chip4).
