Transcriptome of red oak leaf lettuce grown under OSC filters

ABSTRACT: To characterize plant growth in net zero energy greenhouse models with semi-transparent organic solar cell (OSC) filter roofs, RNA was extracted from red oak leaf lettuce leaves grown under 3 OPV filters (FTAZ:IT-M, PTB7-Th:IEICO-4F, FTAZ:PCBM) an clear and shaded glass controls. 2 light intensity experiments were used. PPPFD Controlled (PC) treatments had a constant light intensity and different light spectra created by the filters. Height Controlled (HC) treatments varied in both light intensity and spectra, according to the light transmission of each filter. When light intensity was controlled, plants grown under FTAZ:IT-M had a DEG profile distinct from plants grown under the other 2 filters. Key genes were up or down-regulated that indicate changes in anthocyanin accumulation, nitrogen metabolism and pest defense.

Transcriptome of tomato leaf tissue grown under OSC filters

Project description:To characterize plant growth in net zero energy greenhouse models covered with semi-transparent organic solar cells (OSCs), RNA was extracted from tomato leaf tissue. Six experimental treatments were created with three OSC filters: FTAZ:IT-M, PTB7-Th:IEICO-4F, FTAZ:PCBM. Boxes with either a clear glass cover or a spectrally-neutral cover were used as the high light (HC) control and the comparative light intensity (PC) control, respectively. These treatments were divided into 2 experiments. 4 treatments (3 OSC boxes and control) had a consistent light intensity and were called the PPFD Controlled (PC) experiment. The other 4 treatments were the Height Controlled (HC) experiment and had more variation in light intensity between treatments due to a consistent distance from the growth chamber light source (height). Plants in the FP_PC treatment flowered one day later than the PC control. FI_PC flowered one day earlier. Gene expression in samples from the FP_PC treatment had a distinct pattern related to flowering initiation.

Measurement of genome-wide gene expression in cyanobacteria grown under simluated natural light conditions [RNA-Seq]

Project description:We used RNA sequencing to measure genome-wide gene expression in the cyanobacterium Synechococcus elongatus PCC 7942 grown under dynamic light regimes that mimic the variation in light intensity seen on a Clear Day in nature, or the rapid changes in light intensity that accompany changes in shading We compare these gene expression dynamics to those of a culture grown under a Low Light condition that mimics the standard laboratory conditions used for study of cyanobacteria. Our analysis reveals that naturally relevant light conditions drastically modify gene expression dynamics in cyanobacteria Notably, the expression of circadian clock-controlled genes is responsive to changes in light intensity, showing modulated dynamics that can allow cyanobacteria to adapt their metabolism to changing environmental conditions

Measurement of transcription factor binding in cyanobacteria grown under simluated natural light conditions [ChIP-Seq]

Project description:We used ChIP sequencing to measure genome-wide binding of transcription factors in the cyanobacterium Synechococcus elongatus PCC 7942 grown under dynamic light regimes that mimic the rapid changes in light intensity that accompany changes in shading. Our analysis reveals that rapid changes in light intensity modulate the binding of RNA polymerase (RNAP) upstream of genes in a way that correlates with changes in downstream gene expression, suggesting that changes in transcriptional regulation control light-responsive gene expression changes. Also, binding of the circadian clock-controlled transcription factor RpaA and the light-responsive transcription factor RpaB change upstream of genes in a manner correlating with RNAP enrichment and downstream gene expression. This suggests that changes in RpaA and RpaB binding upstream of genes regulate the light-responsive expression of genes in cyanobacteria.

UV-B regulation of microRNAs in maize

Project description:Differential expression of microRNAs was studied in maize leaves after an 8-h-exposure under UV-B light. As a control, plants were kept in the greenhouse in the absence of UV-B 4-week maize plants were grown in the greenhouse in the absence of UV-B. Then, they were divided in two groups. One group was treated with UV-B lights provided once for 8 h, starting 3 h after the beginning of the light period, using fixtures mounted 30 cm above the plants (Phillips, F40UVB 40 W and TL 20 W/12) at a UV-B intensity of 2 W m-2, UV-A: 0.65 W m-2. The bulbs were covered with cellulose acetate to exclude wavelengths <280 nm. For the second control group, plants were exposed for 8 h under the same lamps covered with polyester film (no UV-B treatment, UV-B: 0.04 W m-2, UV-A: 0.4 W m-2). Lamp output was recorded using a UV-B/UV-A radiometer (UV203 A+B radiometer, Macam Photometrics, Ltd, Livingston, UK) to insure that both the bulbs and filters provided the designated UV dosage in all treatments. Leaf samples were collected immediately after irradiation. RNA was extracted immediately after the treatments, and used for the microRNA microarray experiments.

Microarray analysis of gene expression under different light conditions

Project description:The size of tomato fruits are largely dependent on growth conditions. To obtain insights on how light intensity contributes to translocation from a leaf and a fruit, we developed a plant irradiation system based on light-emitting diodes (LEDs) to a leaf. By using this system, we investigated the changes of transcript profiles of tomato leaves and fruits grown under different light conditions.
