Project description:Microarrays were used to evaluate the effect of sucrose on gene expression in guard cells. Strips of Arabidopsis leaves were incubated with sucrose or mannitol or no sugars, then the leaves were freeze dried and guard cells were dissected from the leaf strips and analyzed.

Project description:Arabidopsis thaliana ecotypes Columbia (Col-0) (wild type: WT) was used in this study. After sterilization, the seeds were placed on Murashige and Skoog medium supplemented with 2% (w/v) sucrose for 10 days and then the seedling were transferred to soil under 16 hours light (22°C) / 8 hours dark (18°C) period in growth chamber at a light intensity of 120?150 µmol m-2 s-1. 20-day-old Arabidopsis leaves without bolting were immediately frozen in liquid nitrogen for RNA and protein and metabolites extraction. Leaves were harvested at three different time points: t = 0 hr (end of night), t = 1 hr (one hour after light turn on) and t = 8 hr (eight hours after light turn on), respectively.

Project description:Microarrays were used to evaluate the effect of sucrose on gene expression in guard cells. Strips of Arabidopsis leaves were incubated with sucrose or mannitol or no sugars, then the leaves were freeze dried and guard cells were dissected from the leaf strips and analyzed. RNA was extracted from guard cells dissected from leaf strips that had been treated with sucrose or with mannitol or no sugars as controls. Triplicate biological replicates were prepared for the treatments and controls. The RNA was amplified twice with T7 RNA polymerase and hybridized to Affymetrix ATH1 arrays.

Project description:Plant respiration responses to elevated growth [CO2] are key uncertainties in predicting future crop and ecosystem function. In particular, the effects of elevated growth [CO2] on respiration over leaf development are poorly understood. This study tested the prediction that, due to greater whole-plant photoassimilate availability and growth, elevated [CO2] induces transcriptional reprogramming and a stimulation of nighttime respiration in leaf primordia, expanding leaves, and mature leaves of Arabidopsis thaliana. In primordia, elevated [CO2] altered transcript abundance, but not for genes encoding respiratory proteins. In expanding leaves, elevated [CO2] induced greater glucose content and transcript abundance for some respiratory genes, but did not alter respiratory CO2 efflux. In mature leaves, elevated [CO2] led to greater glucose, sucrose and starch content, plus greater transcript abundance for many components of the respiratory pathway, and greater respiratory CO2 efflux. Therefore, growth at elevated [CO2] stimulated dark respiration only after leaves transitioned from carbon sinks into carbon sources. This coincided with greater photoassimilate production by mature leaves under elevated [CO2] and peak respiratory transcriptional responses. It remains to be determined if biochemical and transcriptional responses to elevated [CO2] in primordial and expanding leaves are essential prerequisites for subsequent alterations of respiratory metabolism in mature leaves.

Project description:Genome-wide transcriptome analysis of Arabidopsis thaliana was performed to understand the role of auxin in the response of leaf growth to osmotic stress. We studied transcriptional changes in proliferating leaves of the seedlings grown in vitro on control medium, medium supplemented with 25mM mannitol, 0.1μM NAA and 0.1μM NAA + 25mM mannitol.

Arabidopsis plants were grown in either ambient (370 ppm) or elevated (750 ppm) CO2. Leaf number 10 was harvested when it was a primordia, expanding, or mature in each of the CO2 treatments.

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.
