Characterization of gene expression profile in developing soybean seeds by DNA microarray

ABSTRACT: Gene expression profiles in soybean seeds at 4 developmental stages, pod, bean 2 mm, bean 5 mm, and full-sized bean, were examined by DNA microarray analysis. Total genes of each samples were classified into 4 clusters according to developmental stages. Differentially expressed genes (DEGs) were extracted by comparing their expression in two adjacent stages, by using the rank product method. To characterize the gene expression during seed development, DEGs were sorted into 8 clusters by the hclust function, according to gene expression patterns. Keywords: time course Soybean seeds were selected at successive stages of early development for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain transitional changes in gene expression during seed develpment.

Glycinin-deficient species Nanahomare expressing stress-related genes GST and APX during seed maturation

Project description:Global analyses on gene expression profiles in two soybean species, Nanahomare and Tamahomare was performed using DNA microarray technique. Nanahomare is glycinin deficient species, and is high in free amino acid content. Tamahomare is parent species of Nanahomare. In Nanahomare, stress related genes glutathione S-transferase and ascorbate peroxidase had higher expression than in Tamahomare, which suggests glycinin-deficiency caused stress in soy seeds, and that it lead Nanahomare to increase in free amino acid content. Keywords: storage protein deficiency Soybean seeds were selected at two stages of Bean 5mm and Full-size for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain difference in gene expression between two species and find out which gene's or gene group's expression changes.

In-depth investigation of low-abundant proteins in matured and filling stages seeds of Glycine max by a combination of protamine sulfate precipitation and TMT-based quantitative proteomic analysis

Project description:The presence of seed storage proteins is a major bottleneck in soybean seed proteome analysis despite the significant technical advancements in mass spectrometry and data analysis software. Our previous studies have shown that effective ways to improve the detection of low-abundance proteins in soybean seeds using protamine sulfate (PS) with 2-DGE analysis. Besides, verification of the PS precipitation method revealed broad application to other leguminous plants like pea, broad bean, and peanut. Nonetheless, it is difficult to overcome the poor reproducibility and limitation of the dynamic range of identification during 2-DGE analysis. Thus, to elucidate the suitability and efficacy of protamine sulfate precipitation method for shotgun proteome approach, we performed TMT-based quantitative analysis using matured and filling stages seeds by application of two-way pre-fractionation using PS and chromatographic methods. Interestingly, this approach led to the identification of 2,200 and 924 differential proteins in the matured and filling stage of soybean seeds, respectively. These results revealed enrichment of various proteins related to major metabolism in soybean seeds including amino acid, major carbohydrate, lipid metabolism, and among others. Taken together, results provided the new insight into current complexity and limitation of soybean seed proteomics through two-way pre-fractionation combined with TMT-based quantitative analysis.

Identification of genes differentially expressed between developing seeds of different soybean varieties

Project description:Soybean is a rich source of protein and oil and a primary feedstock for biodiesel production. Previous research on soybean indicated that protein, oil and yield are controlled quantitatively in soybean seeds. However, genetic mechanisms controlling seed composition and yield in soybean remain unknown. We used Affymetrix Soybean GeneChips® to identify genes that are differentially expressed between developing seeds of the Minsoy and Archer soybean varieties, which differ in seed weight, yield, protein content and oil content. Some of the differentially expressed genes identified in this study may play important roles in controlling these traits. The soybean plants of two soybean varieties Minsoy and Archer and two recombinant inbred lines from the cross that are similar in maturity but differ in yield were grown in St Paul, Minnesota during the summers of 2007 and 2008. In 2007, each line was planted as a single row. In 2008, a randomized complete block (RCB) design was used and each line had 3 replicates planted 1-2 weeks apart. Within each replicate, two rows per line were planted. Seeds were harvested at three developmental stages, namely, seed length = 2 mm, 3.5 mm, and 5-6 mm, which correspond approximately to soybean reproductive stages R4, R5 and early R6, respectively. In 2007 three independent samples were collected for each line and developmental stage. In 2008, two seed samples (one from each row) were collected for each line at each stage within each replicate. The pairs of seed samples were then pooled. Thus, three sets of independent tissue samples were collected for RNA extraction and hybridization on Affymetrix microarrys.

Dissecting the temporal genetic networks programming soybean embryo development from embryonic morphogenesis to post-germination

Project description:To understand the molecular events underlying seed desiccation and germination, we performed transcriptome analysis of soybean (Glycine max) embryos at three seed developmental stages (early, mid and late desiccation), mature dry seeds, and three germination stages (3, 16 and 27 hour-after-imbibition).

Gene Expression Changes in the Development of the Soybean Seed

Project description:This experiment combines four RNA-Seq datasets of soybean seeds at the following developmental stages: 1) seed globular stage, E-GEOD-57349 (https://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-57349/); 2) seed heart stage, E-GEOD-57350 (https://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-57350/); 3) seed cotyledon stage, E-GEOD-57606 (https://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-57606/) and 4) seed early maturation stage, E-GEOD-46096 (https://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-46096/). Authors 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. Authors sequenced messenger RNA populations of specific soybean seed compartments to provide new insights into gene expression that are important for âmaking a soybean seed.â

Genome-Wide Transcript Profiling During Soybean Seed Development and Throughout the Soybean Life Cycle

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.
