Project description:MicroRNAs (miRNAs) are important post-transcriptional regulators of plant development. In soybean (Glycine max), an important edible oil crop, valuable lipids are synthesized and stored in the cotyledons during embryogenesis .This storage lipids are used as energy source of the emerging seeds, during the germination procces. Until now, there are no microRNAs related to lipid metabolism in soybean or any other plant. This work aims to describe the miRNAome of germinating seeds of B. napus by identifying plant-conserved and novel miRNAs and comparing miRNA abundance in mature versus germinating seeds. A total of 183 familes were detected through a computational analysis of a large number of reads obtained from deep sequencing from two small RNA libraries of (i) pooled germintaing seeds stages and (ii) mature soybean seeds. We have found 39 new mirna precursors which produce 41 new mature forms. The present work also have identified isomiRNAs and mirnas offset (moRNAs). This work presents a comprehensive study of the miRNA transcriptome of soybean germinating seeds and will provide a basis for future research on more targeted studies of individual miRNAs and their functions in lipid consumption in development soybean seeds.

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 â??making a soybean seed.â?? Seventeen compartments of the Early Maturation stage of the soybean seeds were analyzed. Three to four biological replicates were collected for each compartment.

Project description:We performed small-RNA profiling of soybean seed regions and sub-regions, to gain new insights into the regulatory processes required for seed differentiation. Seventeen subregions of the Early Maturation stage of the soybean seeds were analyzed. Two biological replicates were collected for each subregions.

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, early maturation-stage, mid-maturation-stage, and late-maturation-stage embryos. We also profiled dry soybean seeds, and vegetative and reproductive tissues including leaves, roots, stems, seedlings, and floral buds.

Project description:We present results from deep sequencing of small RNA populations from several genotypes of soybean and demonstrate that the CHS siRNAs accumulated only in the seed coats of the yellow varieties having either the dominant I or i-i alleles and not in the pigmented seed coats with homozygous recessive i genotypes. However, the diagnostic CHS siRNAs did not accumulate in the cotyledons of genotypes with the dominant I or i-i alleles thus demonstrating the novelty of an endogenous inverted repeat region of CHS genes driving RNA silencing in trans of non-linked CHS family members in a tissue-specific manner. The phenomenon results in inhibition of a metabolic pathway by siRNAs in one tissue allowing expression of the flavonoid pathway and synthesis of secondary metabolites in other organs as the chalcone synthase small RNAs are found in the seed coats of yellow seeded soybean varieties but not in the cotyledons of the same genotype. In order to compare the population of chalcone synthase related small RNAs, we sequenced 3 to 6 million small RNAs using the Illumina Genome Analyzer from the following four soybean cultivars and tissues with specific genotypes at the I locus: Richland immature seed coats (homozygous for the dominant I allele that specifies yellow seed coat); Williams immature seed coats (homozygous for the dominant i-i allele that specifies yellow seed coat with pigmented hilum) Williams (i-i/i-i yellow) immature cotyledons (homozygous for the dominant i-i allele that specifies yellow seed coat with pigmented hilum); Williams 55 immature seed coats (a Williams isogenic line homozygous for the recessive i allele that specifics pigmented seed coats. All seed coats and cotyledons were dissected from green stage immature seeds within the fresh weight range of 50-75 mg.
