Project description:Plant seeds prepare for germination already during seed maturation. We performed a detailed transcriptome analysis of barley grain maturation, desiccation and germination in two tissue fractions (endosperm/aleurone = e/a and embryo = em) using the Affymetrix barley1 chip. Keywords: time course

Project description:Seeds germination is seriously sensitive to salt stress. The mechanism in response to salt stress during seed germination is still little known. In this study, two genotypes of hulless barley lk621 and lk53 were selected to investigate the molecular mechanism of seeds salinity response during germination stage through RNA-seq and iTRAQ technologies

Project description:Malting is seed germination under strictly controlled environmental conditions. Malting quality is a complex phenotype that combines a large number of interrelated components, each of which shows complex inheritance. Currently, only a few genes involved in determining malting quality have been characterized. This study combined transcript profiling with phenotypic correlations to identify candidate genes for malting quality. We used the Barley1 GeneChip® array to identify differentially expressed genes in four malting stages relative to dry seed in the barley variety Morex, and to identify differentially expressed genes among four barley varieties. Experiment Overall Design: Four malting barley cultivars were micromalted: Morex and Legacy (6-row), Merit and Harrington (2-row). Two to three batches of micromalting (biological replications) were performed. For each micromalting experiment, 20 g samples were collected for Morex at four stages: steeping, 24 h germination (day 1), 93 h germination (day 4), and finished malt after kilning was completed. Ungerminated, dry seed of Morex was used as reference sample. In another experiment, seeds of Legacy, Harrington, and Merit were micromalted and 20 g samples were collected for each variety during day 1 and day 4 germination stages. Expression profiles were compared among the four cultivars separately for day 1 and day 4.

Project description:Plant seeds prepare for germination already during seed maturation. We performed a detailed transcriptome analysis of barley grain maturation, desiccation and germination in two tissue fractions (endosperm/aleurone = e/a and embryo = em) using the Affymetrix barley1 chip. Experiment Overall Design: Barley developing and germinating seeds were harvested at different time points after flowering (developing) and imbibition (germinating). To further disseect the influence of different tissues, seeds were dissecte and tissues were analyzed individually.

Project description:Seed germination triggers a transition of growth and metabolic activities from quiescent to active statuses. Germinating seeds is a good system to study many biological and biochemical processes including hormone metabolic activities and cell wall biosynthesis. Next generation sequence technology is used to study these processes. We have examined gene transcription activities and alternative splicing events in germinating embryos We dissected barley embryos from four barley varieties at 2 time points 24 h and 48 h

Project description:The phytohormone gibberellic acid (GA) is well known to promote seed germination in plants. One of its functions is to stimulate the production of hydrolytic enzymes in the aleurone and their secretion to the adjacent endosperm. The storage in the endosperm is thus degraded by these hydrolases into small molecules, which are utilized as nutrients for embryo growth to establish the young seedling. ABA in contrast plays antagonistic role to GA to keep seed in dormancy. Cereal aleurone has been established as a model system to investigate giberrellin (GA) and abscisic acid (ABA) responses. Using Barley 1 GeneChip, we examined the mRNA accumulation of over 22 000 genes in barley aleurone treated with GA, ABA, GA plus ABA, and sln1 mutant. Barley aleurone tissues were separated from half-seed without embryo. Three independent RNA samples for each treatment including the control without any hormone were extracted and hybridized onto Affymetrix microarrays. We also did microarray in three replications for sln1 mutant aleurone without hormone treatment.
