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:To understand gene expression networks leading to functional properties and compositional traits of the soybean seed, we have undertaken a detailed examination of soybean seed development from a few days post-fertilization to the mature seed using Illumina high-throughput transcriptome sequencing (RNA-Seq). RNA was sequenced from seven different stages of seed development, yielding between 12 million and 78 million sequenced transcripts. These have been aligned to the 79,000 gene models predicted from the soybean genome recently sequenced by the Department of Energy Joint Genome Institute. Over one hundred gene models were identified with high expression exclusively in young seed stages, starting at just four days after fertilization. These were annotated as being related to many basic components and processes such as histones and proline-rich proteins. Genes involved with some storage proteins such as glycinin and beta-conglycinin had their highest expression levels at the stages of largest fresh weight, confirming previous knowledge that these storage products are being rapidly accumulated before the seed begins the desiccation process. Other gene models showed high expression in the dry, mature seeds, perhaps indicating the preparation of pathways needed later, in the early stages of imbibition. Many highly-expressed gene models at the dry seed stage are, as expected, annotated as hydrophilic proteins associated with low water conditions, such as late embryogenesis abundant (LEA) proteins and dehydrins, which help preserve the cellular structures and nutrients within the seed during desiccation. Hundreds of transcription factors with notable expression in at least one stage of seed development were also identified and examined. Results from a second biological replicate demonstrate high reproducibility of these data. High-throughput sequencing using Illumina Genome Analyzer II and Illumina HiSeq 2000 (RNA-Seq) was performed on seven stages of soybean seeds, with two biological replicates per stage.

Project description:Analysis of flanking genomic sequences of unique small RNAs enabled identification of 419 miRNAs. Expression analysis revealed that miRNAs were differentially expressed in different tissues and development stages. Prediction of the miRNA target genes suggested that they are involved in important processes in soybean growth and development. Most conserved soybean miRNAs guide the cleavage of conserved genes. Our study significantly increased the number of known conserved and non-conserved miRNAs in soybean. Our description of soybean miRNAs can be used for functional characterization. one sample, We sequenced 2,570,250 small RNAs representing 1,157,365 unique sequences from different soybean tissues using sequence-by-synthesis high-throughput sequencing

Project description:Plants initially undergo a period of vegetative development, in which it produces leaves from shoot apical meristem (SAM) and roots from the root apical meristem. Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. In this study, we have analyzed the spatial and temporal gene expression in various tissues/organs and developmental stages of rice using microarray technology to identify the genes differentially expressed during various stages of reproductive development.

Project description:We investigated soybean seed development because (1) soybean seeds are a major source of food and fuel, (2) soybean seeds have been an excellent system for studying the basic processes controlling seed development for over three decades, and (3) new soybean genomic resources, including the sequence of the soybean genome and the gene expression profiles for all seed compartments, tissues, and cell types, can be used to gain new insights into the regulatory processes required for seed differentiation. We sequenced messenger RNA populations of specific soybean seed compartments, which will provide new insights into gene expression that are important for “making a soybean seed.”
