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

ABSTRACT: 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.

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

Project description: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.

R7 Soybean seed organelle enrichment proteomics

Project description:This data is part of a study examining the results of increased malic enzyme activity in soybean seeds. The study characterizes changes to oil content and free amino acids when malic enzyme is expressed in different subcellular locations. Malic enzyme was expressed using seed-specific promoters to target activity to the seeds and was also designed to localize into and outside of the chloroplast.

mRNA changes following induction of GmWRI1 activity in Arabidopsis leaf mesophyll protoplasts

Project description:Understanding the mechanisms of transcriptional regulation for genes involved with FA biosynthesis and TAG accumulation in seeds can represent an important step in the development of crops with increased oil content. Among well studied transcription factors (TFs), WRINKLED1 (WRI1), a member of the APETALA2 (AP2) family of TFs, has been characterized as a central regulator of FA biosynthesis in seeds of many plant species. Despite its importance for the process, the detailed mechanisms of WRI1 function in regulating FA biosynthesis in seeds is still not well understood. This study aimed to characterize the gene networks controled by WRI1 during soybean embryo development and its function as central regulator of FA biosynthesis and TAG accumulation in seeds. In this part of the study, we identified genes regulated by the soybean WRI1s (GmWRI1s) by overexpressing GmWRI1-A (Glyma.08G227700) in Arabidopsis leaf mesophyll protoplasts, and identifying the mRNAs that are induced 16h after transfection.

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.

RNA-seq of soybean lines varying in oil composition and content

Project description:Genetic/genome diversity underlying variation in seed oil composition and content among soybean varieties is largely attributed to differences in transcript sequences and/or transcript accumulation of oil production related genes in seeds. Discovery and analysis of sequence and expression variations in these genes will accelerate soybean oil quality improvement. In an effort to identify these variations, we sequenced the transcriptomes of soybean seeds from nine lines varying in oil composition and/or total oil content. Our results showed that 69,338 distinct transcripts from 32,885 annotated genes were expressed in seeds. A total of 8,037 transcript expression polymorphisms and 50,485 transcript sequence polymorphisms (48,792 SNPs and 1,693 small Indels) were identified among the lines. Effects of the transcript polymorphisms on their encoded protein sequences and functions were predicted. The studies also provided independent evidence that the lack of FAD2-1A gene activity and a non-synonymous SNP in the coding sequence of FAB2C caused elevated oleic acid and stearic acid levels in soybean lines M23 and FAM94-41, respectively. As a proof-of-concept, we developed an integrated RNA-seq and bioinformatics approach to identify and functionally annotate transcript polymorphisms, and demonstrated its high effectiveness for discovery of genetic and transcript variations that result in altered oil quality traits. The collection of transcript polymorphisms coupled with their predicted functional effects will be a valuable asset for further discovery of genes, gene variants, and functional markers to improve soybean oil quality. transcriptome comparison of nine different soybean varieties

soybean seeds proteomics analysis of parents and recombinant inbred lines

Project description:Soybean (Glycine max) is one of the most important economic crops. The protein and oil content traits in its seeds usually show a negative correlation, which is worthy of further study. Compared mature seeds of the high-protein soybean Tokachi long-leaf and high-oil soybean Zhonghuang 35, as well as the recombinant inbred lines of high-protein/low-oil populations and high-oil/ low-protein populations by proteomic analysis, it was found that there is a good repeatability and clear separation of proteomes with protein or oil content traits
