Project description:Seeds are comprised of three major parts of distinct parental origin: the seed coat, embryo, and endosperm. The maternally-derived seed coat is important for nurturing and protecting the seeds during development. By contrast, the embryo and the endosperm are derived from a double fertilization event, where one sperm fertilizes the egg to form the diploid zygote and the other sperm fertilizes the central cell to form the triploid endosperm. Each seed part undergoes distinct developmental programs during seed development. What methylation changes occur in the different seed parts, if any, remains unknown. To uncover the possible role of DNA methylation in different parts of the seed, we characterized the methylome of three major parts of cotyledon stage seeds, the seed coat, embryonic cotyledons, and embryonic axis, using Illumina sequencing. Illumina sequencing of bisulfite-converted genomic DNA from three parts of soybean cotyledon stage seeds: seed coat (COT-SC), embryonic cotyledons (COT-COT), and embryonic axis (COT-AX).
Project description:What methylation changes are occurring in different parts of early maturation stage seed largely remains unknown. To uncover the possible role of DNA methylation in different parts of early maturation stage seed, we characterized the methylome of seed coats,cotyledons, and the embryonic seed axis using Illumina sequencing. seed coats, cotyledon, and axis
Project description:The nuclei of Glycine max from different tissues were collected. The samples were: soybean seed mid-maturation stage (10mm), seed late cotyledon stage (5mm), seed early cotyledon stage (3mm), seed heart stage (1mm), soybean green pods without seeds (stage), soybean flower bud (early flowering stage), soybean shoot apical meristem (stage), soybean trifoliate leaf (R5 stage), and soybean true leave (stage). The library construction was performed applying 10 Genomics technology.
Project description:There are four major seed developmental phases in Arabidopsis seed development: morphogenesis, maturation, dormancy and germination. What methylation changes occurring in the different phases, if any, remains unknown. To uncover the possible role of DNA methylation in different parts of the seed, we characterized the methylome of four major seed developmental phases of Arabidopsis using Illumina sequencing: global stage (glob) and linear cotyledon stage (lcot) for morphogenesis phase; mature green stage (mg) and post mature green stage (pmg) for maturation phase; dry seed (dry) for dormancy phase; leaves (leaf) from 4 week plant for vegetative tissues. Illumina sequencing of bisulfite-converted genomic DNA from six seed developmental stages in Arabidopsis: global stage (glob), linear cotyledon stage (lcot), mature green stage (mg), post mature green stage (pmg), dry seed (dry) and leaves (leaf) from 4 week plant.
