Project description:Effect of the low phytic acid mutation on gene expression of developing seeds of M955, a low phytic acid barley genotype with >90% reduction in phytic acid in mature seeds. Expression analysis using the Barley1 GeneChip was performed on total RNA from developing seeds (7DAA) of M955 lpa and wt sib-selections. Sib-selections were from BC2 populations of M955 with Harrington as the recurrent parent. Material was grown in field trials in two years 2003 and 2004. In 2003 expression analysis was done from 2 lpa and 3 wt sib-selections, and in 2004 analysis was done from 2 lpa and 2 wt sib-selections. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, David Bowen.

Project description:Global gene expression analysis of grapevine cv. Pinot Noir berries during development and ripening. Time-course comparison of samples collected at three developmental stages (stages 33, 34 and 36 according to the modified E-L system, ref: Coombe BG, Aust J Grape Wine Res 1995, 1: 104-110) during three seasons (2003, 2005 and 2006). Data for each of the three seasons were normalized independently within each season, using gcRMA.

Project description:The Texas Potato breeding program has been succesful at bringing several potato variety including somaclonal selection made in the field. This genetic diversity is in part due to somaclonal variability that appears within potato selections for which tubers are used as seeds. However, nogenetic or molecular evidences were identified so far. In this investigation, we used RNA-seq, which allows genome-wide gene expression analysis to compare the transcriptomes of the subclonal Russet Norkotah selection TXNS278 with standard Russet Norkotah grown in commercial fields. Among the selections, TXNS278 appeared in a multi- year analysis as a top No 1 yielding variety. Russet Norkotah and TXNS278 leaf and root transcriptomes were compared at two time points. Results indicated that yield differences between Russet Norkotah and TXNS278 might possibly be linked to differences in responses to biotic and abiotic stresses and hormonal signaling

Project description:Purpose: Our previous experiments showed that LPA activated inhibitory G-protein signaling in human GPR35-transfected cells. We wanted to test the LPA signaling in presence or absence of GPR35. Methods: We isolated RNA from bone-marrow derived macrophages (BMDMs) from WT or GPR35-deficient mice that were treated with LPA or LPS, and left untreated for control. Results: We have found that GPR35-deficiency alters the transcriptional profiles in response to LPA in BMDMs. On the other hand, LPS-treated WT and GPR35-deficient BMDMs showed similar transcriptional changes. Conclusion: GPR35-deficientcy alters the LPA but not LPS signaling.

Project description:The experiment was conducted using four 11-year-old potted grapevines of V. vinifera L. cv. Cabernet Sauvignon grafted on SO4 (Selection Oppenheim No. 4) grown in a phytotron. Vines were trained on a Guyot trellising system and each vine carried 4-10 clusters of grapes. The experiment started approximately 1 week before veraison, when berry softening started, and continued to fruit maturity. The two temperature regimes consisted of a high day (06.00–20.00 h) temperature (max.35C) and a control (max. 25C). Under both conditions, the night-time (20.00–06.00 h) temperature was 20C.

Project description:Time-course expression profiles of Bgh challenged barley cultivar C.I. 16151 (harboring the Mla6 powdery mildew resistance allele) and its fast-neutron-derived "Bgh-induced tip cell death1" mutant, bcd1, were compared using the 22K Barley1 GeneChip. Planting, stage of seedlings, harvesting, and experimental design were part of a larger experiment described by Caldo et al. (2004). PLEXdb BB4. Experiment Design: C.I. 16151 (wildtype) and bcd1 (mutant) were planted in separate 20 x 30-cm flats using sterilized potting soil. Each experimental flat consisted of six rows of 15 seedlings, with rows randomly assigned to one of six harvest time points (0, 8, 16, 20, 24, and 32 hai). Seedlings grown to the 1st leaf stage with 2nd leaf unfolded were inoculated with a high density of fresh conidiospores (84 +/- 19 spores/mm2). Groups of flats were placed at 18C (8-hour darkness, 16-hour light) in separate controlled growth chambers corresponding to the Bgh isolates. Rows of plants were harvested at each assigned time points and snap frozen in liquid nitrogen. The entire experiment was repeated three times in a standard split-split-plot design with 72 experimental units (2 genotypes x 2 pathogen isolates x 6 time points x 3 replications). Treatment Description: The samples constituted pairwise combinations of the the cultivar C.I. 16151(containing the Mla6 resistance allele), and its fast-neutron-derived "Bgh-induced tip cell death1" mutant, bcd1 with the two Bgh (Blumeria graminis f. sp. hordei) isolates, 5874 (AvrMla6, AvrMla1) and K1 (AvrMla13, AvrMla1). For each replication, individual genotypes were planted in separate 20 x 30 cm flats using sterilized potting soil. Each experimental flat consisted of six rows of 15 seedlings, with rows randomly assigned to one of six harvest times (0, 8, 16, 20, 24, and 32 hai). Seedlings were grown to the 2nd-leaf stage with 1st leaf unfolded, and inoculation was performed at 4 PM Central Standard Time by tipping the flats at 45oC and dusting the plants with a high density of fresh conidiospores [84 +/- 19 spores/mm2]. This procedure was repeated from the opposite angle to ensure that a high proportion of the cells are in contact with the fungus. This conidial density per unit leaf area routinely results in greater than 50% of epidermal cells that are successfully infected. Groups of flats were placed at 18oC (8 hours darkness, 16 hours light, 8 hours darkness) in separate controlled growth chambers corresponding to the Bgh isolate. Rows of plants were harvested at their assigned harvest times and flash-frozen in liquid nitrogen. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Roger P Wise.
