Eremothecium Coryli

Abstract R. pedestris causes up to 54% reduction in lipid content in soybean seed (Bae et al., 2014) and 8% seed sterility in soybean in Shizuoka Prefecture, Japan (Ikeda and Fukazawa, 1983). In another study, Kadosawa (1981) estimated 6.2% soybean damage in Northern Honshu and 26% in Shikoku, Japan. R. pedestris also transmits yeast-spot disease (Eremothecium coryli) in up to 81.6% of immature soybean seeds in Kyoto, Japan (Kimura et al., 2008). R. linearis damage on soyabean in India is reported to be 30-40% (Kashyap and Adlakha, 1971). R. linearis is estimated to cause (along with two other pod feeders) 19-39% pod and seed damage on soyabean in Indonesia (Supriyatin, 1992). In Nigeria, R. dentipes and Anoplocnemis curvipes cause 20-39% pod damage on Vigna unguiculata (Khaemba, 1984).

Soybeans are an important cash crop and are widely used as a source of vegetable protein and edible oil. MicroRNAs (miRNA) are endogenous small RNA that play an important regulatory role in the evolutionarily conserved system of gene expression. In this study, we selected four lines with extreme phenotypes, as well as high or low protein and oil content, from the chromosome segment substitution line (CSSL) constructed from suinong (SN14) and ZYD00006, and planted and sampled at three stages of grain development for small RNA sequencing and expression analysis. The sequencing results revealed the expression pattern of miRNA in the materials, and predicted miRNA-targeted regulatory genes, including 1967 pairs of corresponding relationships between known-miRNA and their target genes, as well as 597 pairs of corresponding relationships between novel-miRNA and their target genes. After screening and annotating genes that were targeted for regulation, five specific genes were identified to be differentially expressed during seed development and subsequently analyzed for their regulatory relationship with miRNAs. The expression pattern of the targeted gene was verified by Real-time Quantitative PCR (RT-qPCR). Our research provides more information about the miRNA regulatory network in soybeans and further identifies useful genes that regulate storage during soy grain development, providing a theoretical basis for the regulation of soybean quality traits.

Abstract Background: Seeds are the economic basis of oilseed crops, especially for soybean, thus far the most widely cultivated oilseed crop worldwide. Seed development is accompanied with a multitude of diverse cellular processes and revealing the underlying regulatory activities is critical for seed improvement. Results: Here, we profiled transcriptomes of developing seeds (20, 25, 30, 40 days after flowering) representing key points of seed development from early to full development. We identified a set of highly-abundant genes and highlighted the importance of these genes to support nutrient accumulation and transcriptional regulation in developing seeds. We identified 8,925 differentially expressed genes that exhibited temporal expression patterns over the course and had expression specificities in distinct tissues including seeds and non-seed tissues (roots, stems, leaves). Genes with specificities to non-seed tissues have tissue-specialized roles while remain relatively low transcript abundance in developing seeds, exhibiting their supportive roles spatially for seed development. Co-expression network analysis identified several under-explored genes in soybean that bridge tissue-specific gene modules. Conclusions: Our study provides a global view of gene activities and biological processes critical for seed formation in soybean and prioritizes a set of genes for further study. The results shed insight into the mechanism controlling seed development and storage reserves.
