Project description:affy_sunflower_2011_02 - affy_sunflower_2011_02 - The early sowing constitutes an alternative strategy to avoid drought occurring during flowering and post-flowering periods and responsible for decrease in sunflower production. In French cropping system, early sowing is associated to low temperature period and frost during first development stages in sunflower. Knowledge about metabolism of frost acclimation must be performed to supply tools for breeding programs in sunflower. The aim of our experiment is to unravel the transcriptional regulation underpinning frost tolerance in sunflower-5 genotypes of sunflower were grown in a growth chamber 1 (23°C day/18°C night, 63% air humidity, 14 hours day photoperiod). At the stage of 6 leaves well-developed, 12 plants of each genotype were subjected to cold acclimation (+4°C during 2 days) in another growth chamber 2. Then, these plants were subjected to 2 nights at -3°C (frost treatment). Chlorophylle fluorescence, Osmotic potential, Relative electrolyte leakage were then determined in the following conditions : - 6th October on 6 plants X 5 genotypes from growth chamber 1 (C1) - 6th October on 6 plants X 5 genotypes from growth chamber 2 (S1) - 11th October on 6 plants X 5 genotypes from growth chamber 1 (C2) - 11th October on 6 plants X 5 genotypes from growth chamber 1 (S2)

Project description: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.

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. We studied in parallel microRNA profiles on the same samples and we will try to identify sunflower microRNA regulated genes in response to ABA. 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.

Project description:affy_sunyfuel_drought_sunflower - Drought is the main cause or crop loss around the globe and it is expected to be more so in years to come. Helianthus genus comprises species that are able to grow in harsh environments suffering from severe water shortage. Cultivated H.annuus, i.e. sunflower, is a highly valuable oil crop due to, among other features, its ability to grow under low input conditions. The aim of our project is to unravel the transcriptional regulation underpinning drought tolerance in sunflower, with the ultimate goal of improving crop yield. Ninety six individual pots were arranged in six blocks of 16 plants each, which were sown in individual pots. Each block contained 2 plants of 8 different genotypes, one of which was used as control and the other one as treated plant. Plants within each block were randomly arranged. At the right developmental stage, treated plants were water-deprived and their water status was monitored as compared to the untreated control. Three out of the six blocks were harvested on a given date, so water stress among genotypes varied. The plants in the other three blocks were harvested when the treated plant reached a given water stress.
