Project description:We report the genome-wide transcriptome of soybean seeds across several stages of seed development and the entire life cycle using Illumina high-throughput sequencing technology. Specifically, we profiled whole seeds containing globular-stage, heart-stage, cotyledon-stage, and early maturation-stage embryos. We also profiled dry soybean seeds, and vegetative and reproductive tissues including leaves, roots, stems, seedlings, and floral buds. Illumina sequencing of transcripts from whole seeds at five stages of seed development (globular, heart, cotyledon, early-maturation, dry), and vegetative (leaves, roots, stems, seedlings) and reproductive (floral buds) tissues.
Project description:Submergence is a major constraint for soybean production worldwide and transient inundation after seeding causes serious loss of soybean productivity. To characterize genome-scale adjustment of gene expression to submergence and reoxygenation, whole transcriptome analysis was conducted using Affymetrix Soybean Gene 1.0 ST Arrays.

Project description:What methylation changes are occurring during seed development largely remains unknown. To uncover the possible role of DNA methylation during the transition from seed differentiation to maturation and dormany in soybean, we characterized the methylome of whole seeds representing the differentiation (GLOB stage), maturation (early- (EM), mid- (B1) and late- (AA1) maturation stages), and dormancy (DRY stage) phases of soybean seed development using Illumina sequencing. In addition, we characterized the methylome of the mid-maturation stage embryonic axis (B1-AX) to examine methylation differences, if any, between an embryonic region compared to the whole seed. Illumina sequencing of bisulfite-converted genomic DNA from globular stage (GLOB), early-maturation stage (EM), mid-maturation stage (B1), and late-maturation stage (AA1) seeds, dormancy stage (DRY) and mid-maturation embryonic axis (B1-AX).

Illumina sequencing of small RNA from early maturation seed coat parenchyma compartment and early-maturation stage whole seeds
Project description:Long non-coding RNAs (lncRNAs) are defined as non-protein-coding transcripts that are at least 200 nucleotides long. They are known to play pivotal roles in regulating gene expression, especially during stress responses in plants. We used a large collection of in-house transcriptome data from various soybean (Glycine max and Glycine soja) tissues treated under different conditions to perform a comprehensive identification of soybean lncRNAs. We also retrieved publicly available soybean transcriptome data that were of sufficient quality and sequencing depth to enrich our analysis. In total, RNA-seq data of 332 samples were used for this analysis. An integrated reference-based, de novo transcript assembly was developed that identified ~69,000 lncRNA gene loci. We showed that lncRNAs are distinct from both protein-coding transcripts and genomic background noise in terms of length, number of exons, transposable element composition, and sequence conservation level across legume species. The tissue-specific and time-specific transcriptional responses of the lncRNA genes under some stress conditions may suggest their biological relevance. The transcription start sites of lncRNA gene loci tend to be close to their nearest protein-coding genes, and they may be transcriptionally related to the protein-coding genes, particularly for antisense and intronic lncRNAs. A previously unreported subset of small peptide-coding transcripts was identified from these lncRNA loci via tandem mass spectrometry, which paved the way for investigating their functional roles. Our results also highlight the current inadequacy of the bioinformatic definition of lncRNA, which excludes those lncRNA gene loci with small open reading frames (ORFs) from being regarded as protein-coding.
Project description:Submergence is a major constraint for soybean production worldwide and transient inundation after seeding causes serious loss of soybean productivity. To characterize genome-scale adjustment of gene expression to submergence and reoxygenation, whole transcriptome analysis was conducted using Affymetrix Soybean Gene 1.0 ST Arrays. Aerial tissue of soybean which were treated with 1 d submergence, 5 d submergence, and 5 d submergence + 1 d reoxygenation were subjected to RNA extraction and hybridization on Affymetrix microarrays (Soybean Gene 1.0 ST arrays). Non-submerged were used as control. Two independent biological replicates were analyzed for each treatment.
