transition-Transcriptome of floral transition

Project description:ngs2015_01_transition-transition-Identification of transcripts and long non-coding transcripts in wild-type mature rosette leaves of Arabidopsis thaliana during a photoperiodic switch inducing floral transition.-Arabidopsis thaliana Col-0 plants were grown in soil, in growth chamber under white fluorescent light, under short-day (8 hours light/16 hours dark, SD) or long-day (16 hours light/8 hours dark, LD) conditions. Temperature in SD was 21°C during the light period and 18°C during the dark, humidity (65%) remained constant. In LD, temperature (21°C) and humidity (70%) remained constant. Plants were cultured for 4 weeks in individual pot, in SD then transferred in LD. Plants were analysed at different time points before transfer (T0) and after two, three and five days of transfer (T2, T3, T5). The second pair of leaves was collected before dusk, at Zeitgeber time 15 (ZT15) considering ZT 0 the switched on of the light. Three biological replicates were performed. The floral transition occurs between T0 and T5 based on AP1:GUS marker, a inflorescence meristem is not yet visible during this developmental window at the center of the rosette.

photomorphogenesis-Expression profile of DET1-1 mutant during photomorphogenesis

Project description:rs09-01_det1 - photomorphogenesis - - Identification of the genes deregulated in det1-1 when seedlings grow in light or in dark (dark increase morphological differences between det1-1 and wild-type) - Expression profile of seedlings grown in dark then exposed to light - etiolated seedlings (5days) are briefly exposed to light to induce developmental transition between skoto- and photomorphogenesis without visible change in plant morphology and differences between col0 and the mutant det1-1 grown in light or in dark Keywords: treatment variations

Organ-specific light-responsive gene expression profiling assay using 18kA and 18kB soybean cDNA microarrays

Project description:An expression profiling assay comparing dark-grown soybean seedlings with seedlings treated with 1 h far-red light using different organs including cotyledons, hook, and hypocotyl with the soybean cDNA 18kA and 18kB microarray. pairwise comparisons of far-red light treated samples and dark-grown samples in three organs: cotyledons, hook, and hypocotyl. Each comparison was done with 4 biological replicates with a dye swap.

Organ specific analysis of PIFq in Arabidopsis

Project description:The apical hook is the predominant organ to suffer the mechanical pressure and sense the first beam of light when protruding through the soil. In order to understand the organ specific mechanism of this phenomenon, we performed RNA-sequencing analysis using cotyledon, apical hook and hypocotyl organs of 4-day dark grown Col-0 and pifq mutant

Expression data from 7-day-old dark-grown wild-type and dez mutant seedlings from control (1 µM) and high-Zn (100 µM) media

Project description:The transition between growth in the dark (skotomorphogenesis) and growth in the light (photomorphogenesis) is one of the most critical in plant development. Here the newly identified mutant dez is photomorphogenic in the dark and is strongly enhanced in high Zn. dez displays a shortened hypocotyl, expanded cotyledons, an elongated root and differentiated plastids in the dark contrast to wild-type seedlings that are typically skotomorphogenic, with a long hypocotyl and unexpanded cotyledons protected by an apical hook, and undifferentiated etioplasts We used microarrays to identify transcripts regulated in dez in high-Zn relative to wild-type in high-Zn, and dez in high-Zn relative to dez in control conditions.
