Project description:The development of seeds is a process of particular importance both for the plant itself – it assures the survival of the species, and for the human population – for nutritional and economic reasons. Controlling this process requires a strict coordination of many factors at different levels of cellular organization and complexity of regulatory mechanisms, the most important of which are gene transcriptional activity and hormonal homeostasis. In the control of seed filling processes, apart from specific regulatory proteins, the participation of phytohormones is also extremely important. The most important role is attributed to the interdependence between GA and ABA. In many plant species, phytohormones have been shown to affect the expression of genes related to the regulation of storage protein accumulation, especially ABSCISIC ACID INSENSITIVE3 (ABI3) and FUSCA3 (FUS3). The aim of the study was to verify whether exogenous application of phytohormones (ABA or GA) would significantly affect the amount of storage proteins accumulated in yellow lupin seeds.

Project description:Purpose: A time-course transcriptome study to identify probable GA-responsive genes in soybean embryonic axes during seed germination. Methods: Seeds were germinated in the presence or absence of 200 µM PBZ. Seeds were germinated in 28°C temperature and 12/12h photoperiod (dark/light) and harvested at 12, 24 and 36 hours after imbibition (HAI). Three biological replicates were performed. Results: Identification of GA-responsive genes during germination in Glycine max.

Project description:To understand how the NF-YC-RGL2 complex functions in repressing seed germination, a genome-wide transcriptomic analysis was carried out using germinating seeds of rgl2, nf-ycT and the wild-type (Col) grown on the medium containing 5 µM PAC and Col grown on mock treatment. Basing on the criteria of 1.5-fold cutoff for the genes with 5% false discovery rate, we first identified the differentially expressed genes in Col_PAC vs Col_mock, nf-ycT_PAC vs Col_PAC, and rgl2_PAC vs Col_PAC subsets, which are referred to as PAC-, NF-YC-, and RGL2-regulated genes.These data reveal that NF-YCs and RGL2 co-target a set of common genes in response to phytohormone signals, strongly supporting the role of NF-YC-RGL2 in seed germination regulation.

Project description:Experimental Design Type of experiment: In order to evaluate the influence of subinhibitory concentrations of the macrolide antibiotic Azithromycin (AZM) on the global Pseudomonas aeruginosa gene expression, we performed a comparative gene expression analysis of AZM-treated versus untreated P. aeruginosa PAO1 cultures. Experimental factors: P. aeruginosa PAO1 cultures with and without addition of 2 µg/ ml AZM were grown until early stationary phase. Total RNA was extracted when the cultures reached an OD600 of 2.8. The transcriptomes of the untreated cultures were taken as reference values. Both of the AFFYMETRIX Chips of AZM-treated PAO1 (GSM45590, GSM45591) were compared with each of the two chips of the untreated PAO1 (GSM45588, GSM45589). Hybridization procedures and parameters: Hybridization of the probes was carried out according to the manufacturer’s “Expression Analysis Protocol (p. 25: Modified Fluidic Protocol for P. aeruginosa cDNA Assay)”, see http://www.affymetrix.com: Hybridization for 16 h at 50°C and 60 rpm. - Post Hyb Wash 1: 10 cycles of 2 mixes/cycle with Wash Buffer A at 25°C - Post Hyb Wash 2: 4 cycles of 15 mixes/cycle with Wash Buffer B at 50°C - Stain: Stain the probe array for 10 minutes in Streptavidin Solution Mix at 25°C - Post Stain Wash: 10 cycles of 4 mixes/cycle with Wash Buffer A at 30°C - 2nd Stain Wash: Stain the probe array for 10 minutes in antibody solution at 25°C - 3rd Stain Wash: Stain the probe array for 10 minutes in SAPE solution at 25°C - Final Wash: 15 cycles of 4 mixes/cycle with Wash Buffer A at 30°C. The holding temperature is 25°C. Measurement of data and specifications: Data transformation and selection procedures: · The entire signals were scaled to 150 (4% capped median); scaling factors of the arrays were within 3.4 fold of each other, as the % genes called present were in the range of 23.7% and 38.1% for three arrays (GSM455889, GSM45589, GSM45591) and 74,4% for one array (GSM45590). The background levels (Average Background) were similar for all arrays (in a range of 47.20 and 55.64). The Q scores were comparable (in a range of 2.38 and 2.81). The Average Signals of the four arrays were similar (between 187.8 and 228.7). · Scanning hardware: AFFYMETRIX Scanner; software: AFFYMETRIX MAS 5 (Statistical Algorithms Reference Guide, http://www.affymetrix.com/support/technical/technotes/statistical_reference_guide.pdf), MICRO DB 3 and DMT 3 · Image analysis software: AFFYMETRIX MAS 5 Data selection: · Threshold of Signal Log ratio: -1/1; change is I (increased), MI (marginally increased), D (decreased), MD (marginally decreased); change p-value >0.999 or <0.001; only genes that are present (Detection=P) in at least one of the compared chipsets. · Only following genes were considered: Minimal threshold of regulation ±2 fold; minimal change p-values of 0.999 and 0.001, respectively; minimal difference of signal intensities of 200. · The final gene expression data table used by the authors to make their conclusions after data selection and transformation will be published as supplementary data.

Project description:To understand how the NF-YC-RGL2 complex functions in repressing seed germination, a genome-wide transcriptomic analysis was carried out using germinating seeds of rgl2, nf-ycT and the wild-type (Col) grown on the medium containing 5 uM PAC and Col grown on mock treatment. Basing on the criteria of 1.5-fold cutoff for the genes with 5% false discovery rate, we first identified the differentially expressed genes in Col_PAC vs Col_mock, nf-ycT_PAC vs Col_PAC, and rgl2_PAC vs Col_PAC subsets, which are referred to as PAC-, NF-YC-, and RGL2-regulated genes.These data reveal that NF-YCs and RGL2 co-target a set of common genes in response to phytohormone signals, strongly supporting the role of NF-YC-RGL2 in seed germination regulation. Digital gene expression tag profiles of wild type (Col), nf-ycT mutant, and rgl2 mutant germinating seed for 12 h after stratification were generated by deep sequencing, in triplicate, using Illumina HiSeq 2000.

Project description:The phytohormone GA controls multiple important developmental processes in plants such as germination, elongation growth and flowering time. In this experiment, we look for early GA response genes in 7 day-old light-grown Arabidopsis seedlings. To this end we compare four data sets: (1) a GA biosynthesis mutant ga-1 (SALK_109115) mock treated for 1 hr; (2) a GA biosynthesis mutant ga-1 (SALK_109115) treated for 1 hr with 100 µM GA3; (3) a gid1a-1 gid1b-1 gid1c-2 GA receptor triple mutant mock treated for 1 hr; (4) a gid1a-1 gid1b-1 gid1c-2 GA receptor triple mutant treated for 1 hr with 100 µM GA3. In a comparison of the two ga-1 samples, GA regulated genes can be identified, and the assumption is that bona fide GA regulated genes are not responding in the gid1a-1 gid1b-1 gid1c-2 GA receptor mutant.
