(Submitter supplied) 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

(Submitter supplied) 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.

(Submitter supplied) To provide comprehensive spatiotemporal information about biological processes in developing grains of cultivated barley (Hordeum vulgare subsp. vulgare), we performed a chromatin immunoprecipitation of H3K27me3 followed by high-throughput sequencing (ChIP-seq) in barley endosperm at 16 days after pollination.

(Submitter supplied) Soybean (Glycine max) seeds are an important source of seed storage compounds, including protein, oil, and sugar used for food, feed, chemical, and biofuel production. We assessed detailed temporal transcriptional and metabolic changes in developing soybean embryos to gain a systems biology view of developmental and metabolic changes and to identify potential targets for metabolic engineering. Two major developmental and metabolic transitions were captured enabling identification of potential metabolic engineering targets specific to seed filling and to desiccation. more...

(Submitter supplied) affy_sunflower_2010_13 - affy_sunflower_2010_13 - It concerns the interaction between ROS and hormones in dormancy release in sunflower seeds. ABA is responsible for dormancy maintenance, while GA and ethylene promote seed germination. Based on our results, ROS could represent good candidate to shift from a hormone signalling to another determining the dormancy state in sunflower seeds.-We aim to understand the mechanisms controlling sunflower seed dormancy at the transcriptomic level, by the application of treatments which maintain dormancy as ABA, or alleviate dormancy as ROS and ethylene. more...

(Submitter supplied) A spatial resolved transcriptome for germinating barley grain was obtained for over 14,000 genes at 0, 1, 3 6 and 24 hours after imbibition. The spatial expression of a number of genes was validated using in-situ PCR, quantitative comparison to bulk RNA-seq reveal good correlations, despite the differences in the methodologies, and marker gene definition for tissues/clusters was consistent with previous gene specific studies. more...
