Affy_strigolactone_sunflower-Identification of Strigolactone -regulated genes in sunflower

ABSTRACT: affy_strigolactone_sunflower - affy_strigolactone_sunflower - Abiotic stress and more specifically drought is the major limiting factor for sunflower production. Sunflower response to drought includes root plasticity to adapt to water availability and reach soil water. We identified genotype-specific responses of root architecture to strigolactone application. This experiment aims at identifying strigolactone responsive pathways in 6 genotypes in order to better understand molecular control of root development in sunflower and therefore its response to drought. The ultimate goal will be to improve sunflower breeding through selection of key drought response genes.-The experiment consisted of 2 repeats of four 12-day-old-plantlets of 6 sunflower genotype SF193 (INRA code: XRQ), SF326 (INRA code: PSC8), SF056 (INRA code: FU), SF306 (INRA code: PAZ2), SF302 (INRA code: PAC2), SF268 (INRA code: RHA266), grown in growth chamber conditions and submitted to a 24-hour-treatment of 100 nM strigolactone analogue rac-GR24 (Chiralix, Nijmegen, Netherland) or not. Growth conditions were 14h light at 23°C and 10h night at 20°C under fluorescent bulbs. Plants were grown in hydroponic boxes containing 20 litres of aerated liquid culture medium (as described in Massonneau et al., 2001 Planta). The entire root systems were harvested 4 hours after light onset and frozen immediately in liquid nitrogen.

eqtl-Identification of expression QTL of ABA response in sunflower

Project description:affy_eqtl_sunflower - eqtl - Abiotic stress and more specifically drought is the major limiting factor for sunflower production. ABA is a key hormone for drought stress response in plants and sunflower. This experiment aims at identifying ABA responsive pathways in order to better understand sunflower responses to drought. The ultimate goal will be improve sunflower breeding through selection of key drought response genes. The experiment consisted of 1 or 2 (and 3 for the sample 209) repeats of 113 recombinant imbred lines and 11 repeats of the population parents SF1935 (INRA code XRQ), 11 SF326 (INRA code: PSC8) and the F1 hybrid 10 INEDI. The genotypes were grown in growth chamber conditions and submitted to a 6-hour-treatment of 0.5 µM absissic acid or not. Growth conditions were 14h light at 23°C and 10h night at 18°C under fluorescent bulbs. Plants were grown in 18 hydroponic boxes (9 for ABA treatment, 9 for control) containing 20 litres of aerated liquid culture medium (as described in Massonneau et al., 2001 Planta). Leaves (not cotyledons) from the 15-day-old-plantlets of sunflower were harvested 6 hours after treatment; the three repeats were pooled for each genotype and frozen immediately in liquid nitrogen.

Project description:Abiotic stress and more specifically drought is the major limiting factor for sunflower production. ABA is a key hormone for drought stress response in plants and sunflower. This experiment aims at identifying ABA responsive pathways in order to better understand sunflower responses to drought.

The ultimate goal will be improve sunflower breeding through selection of key drought response genes.-The experiment consisted of 3 repeats of four 12-day-old-plantlets of sunflower genotype SF193 (INRA code: XRQ) grown in growth chamber conditions and submitted to a 6-hour-treatment of 10 µM absissic acid or not. Growth conditions were 14h light at 23°C and 10h night at 20°C under fluorescent bulbs. Plants were grown in 6 hydroponic boxes containing 20 litres of aerated liquid culture medium (as described in Massonneau et al., 2001 Planta). Leaves (not cotyledons) 1 to 4 were harvested 4 hours after light onset and frozen immediately in liquid nitrogen.

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.

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.

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.

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.
