Project description:Metabolic and Transcriptional Reprogramming in Developing Soybean (Glycine max) Embryos
| PRJNA197379 | ENA
Project description:Soybean (Glycine max) seeds are an important source of seed storage compounds, including protein, oil, and sugar used for food, feed, chemical, and biofuel production. We assessed detailed temporal transcriptional and metabolic changes in developing soybean embryos to gain a systems biology view of developmental and metabolic changes and to identify potential targets for metabolic engineering. Two major developmental and metabolic transitions were captured enabling identification of potential metabolic engineering targets specific to seed filling and to desiccation. The first transition involved a switch between different types of metabolism in dividing and elongating cells. The second transition involved the onset of maturation and desiccation tolerance during seed filling and a switch from photoheterotrophic to heterotrophic metabolism. Clustering analyses of metabolite and transcript data revealed clusters of functionally related metabolites and transcripts active in these different developmental and metabolic programs. The gene clusters provide a resource to generate predictions about the associations and interactions of unknown regulators with their targets based on “guilt-by-association” relationships. The inferred regulators also represent potential targets for future metabolic engineering of relevant pathways and steps in central carbon and nitrogen metabolism in soybean embryos and drought and desiccation tolerance in plants.

Project description:Microarray expression profiling was used to identify genes expressed in developing soybean (Glycine max) seeds that are controlled by the circadian clock. Plants with developing seeds were entrained to 12hour light: 12 hour dark cycles and sampled in constant light conditions.

Project description:To understand the molecular events underlying seed maturation, quiescence and germination, we performed transcriptome analysis of soybean (Glycine max) embryos at four seed developmental stages (cotyledon, early, mid and late maturation), mature dry seeds, and seedlings, eight days after seed sowing.

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).

Project description:Microarray expression profiling was used to identify genes expressed in developing soybean (Glycine max) seeds that are controlled by the circadian clock. Plants with developing seeds were entrained to 12hour light: 12 hour dark cycles and sampled in constant light conditions. Soybean seeds entrained to 12 hour-light:12 hour dark photocycles were harvested after 24 hours of constant light and temperature conditions. Timepoint 24h represents subjective dawn. To minimize developmental variation, flowers were marked as they opened and seeds were harvested from marked pods after 5 weeks. There are two replicate samples at each time point, and each sample consists of 8 seeds collected from three diffferent plants.

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:Aluminum (Al) toxicity is an important restraint to soybean (Glycine max L. Merr.) production on acid soils. However, little is known about the genes underlying Al tolerance in soybean. We used microarrays to detail the global programme of gene expression under control and Al stress in two soybean at 6, 12, and 24 h.

Project description:Tropospheric ozone (O3) is a secondary air pollutant and anthropogenic greenhouse gas. Concentrations of tropospheric O3 have more than doubled since the Industrial Revolution, and are high enough to damage plant productivity. Soybean (Glycine max L. Merr.) is the worldâs most important legume crop and is sensitive to O3. Current ground-level O3 are estimated to reduce global soybean yields by 6% to 16%. In order to understand transcriptional mechanisms of yield loss in soybean, we examined the transcriptome of soybean flower and pod tissues exposed to elevated O3 using RNA-Sequencing.
