Project description:To further understand the genomics of low light tolerance, Swarnaprabha rice line was subjected to low light or shade stress. The fully emerged panicles were samples at early grain filling stage and microarray was performed from the spikelets. Expression of 12 gene in different pathway were verified using real-time PCR reactions.

Project description:A 50ml culture of Halobacterium NRC-1 knockout strain delta-ura3 with additional in-frame gene deletion of sop2 was grown to mid-log phase in a 125ml flask in rich media under varying oxygen and light conditions. Low and high light indicate growth in a painted flask versus growth in a standard clear flask under constant standard incubator illumination, respectively. Low and high oxygen indicate shaking in a stoppered flask at 100RPM agitation or shaking in a non-stoppered flask at 220RPM, respectively. Each of the four possible pairwise environemental combinations were assayed : High-oxygen/high-light, Low-oxygen/high-light, High-oxygen/low-light and Low-oxygen/low-light. RNA extractions were performed using the Stratagene Absolutely RNA Miniprep Kit and RNA quality checked with the Agilent Bioanalyzer and with Oligo Microarrays were fabricated at the Institute for Systems Biology Microarray Facility. The arrays contain 4 spots per unique 70-mer oligonucleotides for each of 2400 non-redundant genes in Halobacterium NRC-1 Labeling, hybridization and washing have been previously described (Baliga et al. 2002) with 10 μg of RNA from the sample and reference. RNA from the final time point of a replicate experiment was used as the reference. Bias in dye incorporation was accounted for by reversing the labeling dyes (dye-flip). Raw data was processed and converted into log10 ratios with lambda (λ) values determined by a maximum likelihood method.Baliga, N. S., Pan, M., Goo, Y. A., Yi, E. C., Goodlett, D.

Project description:The wild type strain of Halobacterium salinarium strain NRC-1 was used for the diel growth experiments. For experiment, cultures were started at an OD >> 0.001. Cultures were grown anaerobically at a temperature of 38° C under light:dark cycles (12:12 hrs) for 120 hours then grown under constant light. Average light intensity was 150 μE/m2/sec. Time course sampling began 84 hours into the light:dark phase. Samples were collected every 3 hours for 72 hours. At each time point, culture was withdrawn by syringe and replaced with nitrogen gas. Aliquots of the culture were centrifuged and the cell pellet flash-frozen in a dry ice/ethanol bath after decanting the supernatant. RNA extractions were performed using the Stratagene Absolutely RNA Miniprep Kit and RNA quality checked with the Agilent Bioanalyzer and with Oligo Microarrays were fabricated at the Institute for Systems Biology Microarray Facility. The arrays contain 4 spots per unique 70-mer oligonucleotides for each of 2400 non-redundant genes in Halobacterium NRC-1 Labeling, hybridization and washing have been previously described (Baliga et al. 2002) with 10 μg of RNA from the sample and reference. RNA from the final time point of a replicate experiment was used as the reference. For this experiment 3 μl of ULYSIS Alexa Fluor 594 and 6 μl of 660 dyes (Molecular Probes) were used for labeling. Bias in dye incorporation was accounted for by reversing the labeling dyes (dye-flip). Raw data was processed and converted into log10 ratios with lambda (λ) values determined by a maximum likelihood method. Baliga, N. S., Pan, M., Goo, Y. A., Yi, E. C., Goodlett, D.

Project description:Flavonoid biosynthesis in grape berry skin is affected by environmental factors such as light and temperature. However, the components of the light-signaling and low-temperature-induced ABA signaling networks related to flavonoid accumulation in grape berry skin have not been fully elucidated. To clarify details of the possible light- and ABA-related signal transduction networks, we performed comprehensive transcriptome analysis using grape berries cultured under different light and temperature conditions. We identified 40 light-inducible genes, 55 low-temperature-inducible genes, and 34 genes induced by light plus low temperature.

Project description:Internal sugar and light specific dependent regulation of leaf gene expression was addressed by changing [CO2] to lower than compensation point [CO2] in combination with light or prolonged darkness. Plants were grown on soil in a 12/12 h light/dark rhythm at 20°C day and night and under normal [CO2]. 5 weeks after germination, the above-ground rosettes of the non-flowering plants were harvested, 12 plants per sample. Plants were harvested 4hrs after the end of night (i) under low (< 50 ppm) [CO2] and 150 µE fluorescent light , (ii) under normal [CO2] and light, and, (iii) under low [CO2] and prolonged darkness. The low [CO2] treatment started 30 min before the end of night and stopped with harvesting. Experiment Overall Design: 2 biological replicates of plants under 3 treatments (4hrs low CO2+light, 4hrs low CO2+prolonged darkness, and 4hrs normal CO2+light).
