Project description:To investigate how HDC1, HDA6, and HDA19 regulate gene transcription and flowering time in long day conditions, we performed RNA deep sequencing (RNA-seq) to compare the transcriptomes of wild type, hdc1, hda6, and hda19 mutants grown in long day conditions.

Project description:Plants adapt to the prevailing photoperiod by optimally adjusting growth and flowering to the availability of energy. When Arabidopsis thaliana plants are grown in long days individual leaf growth is favoured, whereas whole plant leaf area is decreased because of the rapid shift to floral stages and, consequently, the low number of total leaves. To understand the molecular profiles of adaptation to long-day conditions we profiled Arabidopsis leaf number six of plants grown in 16 hours of light at four developmental stages both at the end of the day and the end of the night and compared the profiles to those acquired in short day conditions.

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:We were interested in changes in small RNA abundance changes in response to developmental transitions in Arabidopsis thaliana shoots, with special focus on vegetative phase change. We specifically wanted to separate the temporal changes in gene expression that result from vegetative phase change and those from flowering. Because of the close timing between the juvenile-to-adult and adult-to-reproductive developmental transitions in Arabidopsis grown under long day conditions, we used the late-flowering genotype FRI;FLC developed by the lab of Richard Amasino by introgressing the FRI allele from Sf-2 into the Col-0 genetic background, which is fri;FLC. For the early flowering genotype, we used FRI;flc-3, also developed by the Amasino lab by EMS-mutagenizing FRI;FLC, identifying early flowering mutants, and backcrossing multiple times to eliminate other EMS-induced mutations. The onset of vegetative phase change in FRI;FLC and FRI;flc-3 under our growth conditions was identical, but the progression was slower in FRI;FLC. By sequencing small RNAs from shoot apices at different time points and fully-expanded leaves at different positions on the shoot and comparing the results between the two genotypes, we were able to obtain a clear picture of changes in small RNA abundance in response to vegetative phase change and flowering in Arabidopsis. For the small RNA samples, we performed two replicates using two different indices in the 5'-adapter and ran each replicate pair on the same sequencing lane. For the cotyledon and leaf samples we only performed one replicate using the same index for all samples because we obtained significantly different results with the two adapters used for the shoot apices, preventing us from using them as true replicates.

Project description:Flowering in plants is a very dynamic and synchronized process where various cues including age, day-length, temperature and endogenous hormones fine-tune the timing of flowering for reproductive success. Arabidopsis thaliana is a facultative long day plant where long-day (LD) photoperiod promotes flowering. Arabidopsis still flowers under short-day (SD) conditions, albeit much later than LD conditions. Although, factors regulating the photoperiodic LD pathway have been extensively investigated, the SD pathway is much less understood. Here we identified a critical transcription factor called bHLH93 (basic Helix-Loop-Helix 93) that is essential to induce flowering specifically under SD conditions in Arabidopsis. bhlh93 mutants do not flower from primary meristem under SD conditions, but flowers similar to wild type under LD conditions. The late flowering phenotype is rescued by exogenous application of GA, suggesting that bHLH93 acts upstream of GA pathway to promote flowering. Double mutant studies showed that bhlh93 is epistatic to phyB and soc1 genes under SD conditions. bHLH93 is expressed at the meristematic regions and its expression peaks at 8 hours after dawn under SD conditions. As expected, the bHLH93 is localized in the nucleus. Taken together, these data suggest that bHLH93 is a key transcription factor necessary for Arabidopsis thaliana to evolve as a facultative plant.

Project description:We were interested in identifying targets of novel putative miRNAs we identified from small RNA sequencing libraries of Arabidopsis shoots. The small RNA (smRNA) sequencing libraries were made to identify changes in abundance of specific smRNAs in response to developmental transitions in Arabidopsis thaliana shoots, with special focus on vegetative phase change. We specifically wanted to separate the temporal changes in gene expression that result from vegetative phase change and those from flowering. Because of the close timing between the juvenile-to-adult and adult-to-reproductive developmental transitions in Arabidopsis grown under long day conditions, we used the late-flowering genotype FRI;FLC developed by the lab of Richard Amasino by introgressing the FRI allele from Sf-2 into the Col-0 genetic background, which is fri;FLC. For the early flowering genotype, we used FRI;flc-3, also developed by the Amasino lab by EMS-mutagenizing FRI;FLC, identifying early flowering mutants, and backcrossing multiple times to eliminate other EMS-induced mutations. The onset of vegetative phase change in FRI;FLC and FRI;flc-3 under our growth conditions was identical, but the progression was slower in FRI;FLC. By sequencing small RNAs from shoot apices at different time points and fully-expanded leaves at different positions on the shoot and comparing the results between the two genotypes, we were able to obtain a clear picture of changes in small RNA abundance in response to vegetative phase change and flowering in Arabidopsis. We then used the remaining RNA to make genome-wide mapping of uncapped and cleaved transcripts (GMUCT) 2.0 libraries of a subset of our samples. GMUCT 2.0 allows you to identify RNAs that are 1) uncapped and in the process of 5’->3’ exonuclease degradation and 2) miRNA and siRNA-mediated cleavage products. We wanted to use these GMUCT 2.0 libraries to identify targets of novel putative miRNAs discovered by our smRNA sequencing, thereby supporting the idea that these novel putative miRNAs are in fact functional.
