Project description:Rats were housed in either long day (LD, 16:8 hours, light:dark) or short day (SD, 8:16 hours, light dark) photoperiods for 3, 14 and 28 days and brains removed, frozen on dry ice and then hypothalamic arcuate nucleus tissue blocks cut for RNA extraction. At each time point 4 rats were used in each photoperiod giving 24 rats in total.

At each time point 4 rats were used in each photoperiod giving 24 rats in total. RNA from each rat was used on separate affymetrix rat 230 2.0 arrays, using 24 in total. Comparison of expression of genes were made between rats from each photoperiod at 3, 14 and 28 day timepoints.

Project description:Natural variation in the barley homolog of CENTRORADIALIS (HvCEN), was found to contribute to the expansion of barley cultivation into diverse habitats. It has been shown that induced hvcen mutants, originally designated as praematurum-c/maturity-c (mat-c) mutants, flowered a few days earlier under natural long-day conditions. All hvcen mutants flowered early and showed a reduction in spikelet number per spike, tiller number and yield in the outdoor experiments. Further evaluating development of main shoot apex of hvcen mutants and wild type under controlled long day and short day conditions showed that mutations in hvcen accelerated spikelet initiation and reduced axillary bud number in a photoperiod independent manner, but promoted floret development only under long days. In this project we investigate the pleiotropic effects of HvCEN on developmental timing and shoot and spike morphologies of barley and dependence on these effects on photoperiod. This RNAseq dataset was generated to identify the putative transcriptional targets of HvCEN. To this end, we used global transcriptome profiling in developing shoot apices and inflorescences of two allelic hvcen mutants (mat-c.907 and mat-c.943) and wild-type (Bonus) plants grown under long- and short-day photoperiods.

Project description:Plants in temperate regions have evolved mechanisms to survive sudden temperature drops. Previous reports have indicated that the cold acclimation mechanism is light-dependent and does not fully operate under a low light intensity. In these studies, plants were grown under a long-day photoperiod and were more sensitive to freezing stress. However, winter annuals like Arabidopsis thaliana Col-0 germinate in the fall, overwinter as rosettes, and therefore must acclimate under short photoperiods and low irradiance. The role of light intensity was analysed in plants grown under a short-day photoperiod at the growth stage 1.14. Plants were acclimated at 4 °C for seven days under 100 and 20 μmol m-2s-1 PPFD for control and limited-light conditions, respectively. All cold acclimated plants accumulated molecular markers reportedly associated with acquired freezing tolerance, including proline, sucrose, CBFs, and COR gene protein products dehydrins and low-temperature-responsive proteins LTIs. Observed changes indicated that low PPFD did not inhibit the cold acclimation process, and the freezing stress experiment confirmed similar survival rates. The molecular analysis found distinct PPFD-specific adaptation mechanisms that were manifested in contrasting content of anthocyanins, cytokinin conjugates, abundances of proteins forming photosystems, and enzymes of protein, energy, and ROS metabolism pathways. Finally, this study led to the identification of putative proteins and metabolite markers correlating with susceptibility to freezing stress of non-acclimated plants grown under low PPFD. Our data show that Arabidopsis plants grown under short-day photoperiod can be fully cold-acclimated under limited light conditions, employing standard and PPFD-specific pathways.

Project description:The primary objective of this project is to determine the physiological and developmental differences between photoperiod and root induced tuberization responses in potato using genomic techniques. These experiments will establish baseline genomic and proteomic response associated with a partially characterized root-produced compound (TIF) that either substitutes for, or over-rides, the primary leaf perceived photoperiod induction signal in potato. The proposed work will answer the following questions. Are photoperiod and root induced tuberization responses the same? Do photoperiod and root induced tuberization trigger the same developmental processes in the stolon? How are photoperiod and root induced signals expressed in the genome of the leaf, stolon and roots? The data from the proposed experiments will prove invaluable in identifying key pathways in specific tissues to target in subsequent experiments in order to determine identify of, and establish the mode of action of the TIF compound.

Project description:To begin understanding transduction of the photoperiod signal, Vitis riparia Michx. (PI588259) grapevines that had grown for 35 days in long photoperiod (long day, LD, 15h) were subjected to either continued LD or a short photoperiod (short day, SD, 13h) treatment. Shoot tips (4-node shoot terminals) were collected from each treatment at 7 and 28 days of LD and SD for proteomic analysis via two-dimensional (2D) gel electrophoresis. The peptides were identified using MALDI-TOF_TOF mass spectrometer after trypsin digestion. A master gel was made and mapped with all p roteins from both photoperiod treatments. The proteins were identified by matching the peptide sequences against the 12X Vitis vinifera grape genome in NCBI. This study was funded in part by NSF grant DBI064755 and the South Dakota Agriculture Experiment Station.

Project description:Replicate populations of Aedes albopictus were reared under diapause-inducing short day photoperiod (8h light: 16h dark) and diapause-averting long day photoperiod (16h light:8h dark). Eggs were collected from each replicate and snap-frozen 11d post-oviposition. We hope to characterize the metabolomic and lipidomic profiles of diapausing eggs relative to non-diapause eggs.
