RNA-seq of Arabidopsis seedlings with the treatment of GR24-5DS

ABSTRACT: This dataset provides deep-profiling of the Arabidopsis transcriptome of mRNA of 7-day whole seedling on treatment with strigolactone (SL) isomer GR24-5DS. To understand the transcriptome response and genes regulated by SL, we used Columbia (Col0) ecotype. 7-day old seedlings are treated with 2.5uM GR24-5DS for 3hrs and samples are frozen immediately after treatment. 6 samples: 3 biological replicates Control untreated; 3 biological replicates treated with GR24-5DS.

ppmax2 response to gr24-Strigopath/Physcomitrella patens

Project description:4plex_physco_2014-05 - ppmax2 response to gr24 - How does the Ppmax2 moss mutant respond to Strigolactone (GR24)? - Two moss genotypes are used: WT and the Ppmax2 mutant. Moss tissues are fragmented, then plated on medium (Petri dish with cellophane disks) and cultivated for 3 weeks. Moss tissues are then transfered for 6 hours on acetone-containing medium (control treatment, for WT and Ppmax2) or GR24 (1 microM, in acetone)-containing medium (for Ppmax2). After 6 hours, the moss tissues are collected, quickly forzen in liquid nitrogen. RNA are isolated using the Quiagen RNeasy Plant mini kit (including a RNase-free DNase treatment on column). Two similar experiments (T1 and T2) have been led.

The response of the root proteome to the synthetic strigolactone GR24 in Arabidopsis

Project description:Strigolactones are plant metabolites that act as phytohormones and rhizosphere signals. Whereas most research on unraveling the action mechanisms of strigolactones is focused on plant shoots, we investigated proteome adaptation during strigolactone signaling in the roots of Arabidopsis thaliana. Through large-scale, time-resolved, and quantitative proteomics, the impact of the strigolactone analog rac-GR24 was elucidated on the root proteome of the wild type and the signaling mutant more axillary growth 2 (max2). Our study revealed a clear MAX2-dependent rac-GR24 response: an increase in abundance of enzymes involved in flavonol biosynthesis, which was reduced in the max2-1 mutant. Mass spectrometry-driven metabolite profiling and thin-layer chromatography experiments demonstrated that these changes in protein expression lead to the accumulation of specific flavonols. Moreover, quantitative RT-PCR revealed that the flavonol-related protein expression profile was caused by rac-GR24--induced changes in transcript levels of the corresponding genes. This induction of flavonol production was shown to be activated by the two pure enantiomers that together make up rac-GR24. Finally, our data provide much needed clues concerning the multiple roles played by MAX2 in the roots and a comprehensive view of the rac-GR24--induced response in the root proteome.

Strigolactone and cytokinin act antagonistically in regulating rice mesocotyl elongation in darkness

Project description:Strigolactones have been defined as a new group of phytohormones that regulate shoot branching. The phenotypes of strigolacton-related rice (Oryza sativa) dwarf (d) mutants demonstrated that SLs inhibit mesocotyl elongation by controlling cell division. Moreover, the trans-zeatin, one of active cytokinins, content of mesocotyls was increased in the SL-deficient d10-1 and SL-insensitive d14-1 mutants. To examine if there are genes related to cytokinin-biosynthesis or -degradation among the strigolactone-responsive genes expressed in the mesocotyl, we carried out microarray analyses using d10-1, d14-1 and the wild-type grown under dark conditions, with or without pretreatment of a synthetic strigolactone analog, GR24. Gene expression profiles in 4-day-old mesocotyls of dwarf (d) mutants (d10-1 and d14-1) and wild-type germinated under dark conditions with or without treatment of 1 μM GR24 were analyzed. Three biological replicates were prepared for each conditions, and a total of eighteen samples were analyzed.

Gene expression profiles following GR24, smoke water and KAR1 treatments in Nicotiana benthamiana seedlings

Project description:GR24, a synthetic strigolactone, and KAR1, the main bioactive compound in smoke water, both share a common α,β unsaturated furanone moiety which promotes biomass accumulation in three week old N. benthamiana seedlings. In order to investigate whether this D ring is responsible for the biomass accumulation, gene expression profiles were evaluated for co-expression on the Agilent 44k N. tabacum microarray. GR24, smoke and KAR1 induced different transcripts, and suggests that they trigger independent growth responses.

Gene expression profiles following GR24, smoke water and KAR1 treatments in Nicotiana benthamiana seedlings

Project description:GR24, a synthetic strigolactone, and KAR1, the main bioactive compound in smoke water, both share a common Î±,Î² unsaturated furanone moiety which promotes biomass accumulation in three week old N. benthamiana seedlings. In order to investigate whether this D ring is responsible for the biomass accumulation, gene expression profiles were evaluated for co-expression on the Agilent 44k N. tabacum microarray. GR24, smoke and KAR1 induced different transcripts, and suggests that they trigger independent growth responses. Control (untreated), GR24 (10-7M), smoke water (1:1000 dilution) and butenolide (10-7M) gene expression profiles were evaluated on three week old seedlings, in two independent experimental trials.
