Project description:RNA-seq was used to characterize gene expression in soybean from a wide range of tissues. The primary focus of the project was small RNAs, and the identification of microRNAs and phased siRNA-generating loci, but RNA-seq data were generated from the same samples. This project was supported by the United Soybean Board.

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:The transition to flowering is characterized by a shift of the shoot apical meristem (SAM) from leaf production to the initiation of a floral meristem. In this study, we addressed the nature of SAM gene networks involved in the early floral initiation process in the crop legume soybean. Unique aspects (such as pod development and nitrogen fixation) of legume development make them appealing for plant development studies. Soybean, a major oilseed crop, possesses varied maturity groups; hence, understanding and unravelling initial transition control has implications in manipulating crop yield. To this end, we performed global gene expression analysis using Affymetrix® soybean GeneChip® with RNA isolated from micro-dissected soybean SAMs at various time points after plants were shifted from long-day to short-day growth conditions. Analysis of the resulting microarray data revealed a total of 331 transcripts that have differential expression profiles. Intriguingly, about 20% of the transcripts affected by the switch in the development program have orthologs reported to be responsive to abscisic acid (ABA), suggesting an increase in ABA levels in the SAM during this developmental change. A subsequent immunoassay verified this, thereby implicating its possible function as an endogenous signal during the floral evocation process. The striking occurrence of abiotic stress-related transcripts, including trehalose metabolism genes, in SAMs during the early transition to floral meristems points to an overlap of abiotic stress and floral signalling pathways in soybean. In addition, other hormones - auxin, jasmonic acid and brassinosteroids - and a number of candidate protein kinases may also act in the signalling process prior to or concurrently with the induction of the putative floral homeiotic transcripts. This indicates that molecular events mediated by multiple hormonal pathways are part of the mechanism employed by soybean to regulate the floral transition process.

Project description:Background: Pollen, the male partner in the reproduction of flowering plants, comprises either two or three cells at maturity. The current knowledge of the pollen transcriptome is limited to the model plant Arabidopsis thaliana, which has tri-cellular pollen grains at maturity. Comparative studies on pollen of other genera, particularly crop plants, are needed to understand the pollen gene networks that are subject to functional and evolutionary conservation. In this study, we used the Affymetrix Soybean GeneChip® to perform transcriptional profiling on mature bi-cellular soybean pollen. Results: Compared to the sporophyte transcriptome, the soybean pollen transcriptome revealed a restricted and unique repertoire of genes, with a significantly greater proportion of specifically expressed genes than is found in the sporophyte tissue. Comparative analysis shows that, among the 37,500 soybean unique transcripts addressed in this study, 10,299 genes (27.46%) are expressed in pollen. Of the pollen-expressed genes, about 9,489 (92.13%) are also expressed in sporophytic tissues, and 810 (7.87%) are selectively expressed in pollen. Overall, the soybean pollen transcriptome shows an enrichment of transcription factors (mostly zinc finger family proteins), cell cycle-related transcripts, signal recognition receptors, ethylene responsive factors, chromatin remodeling factors, and members of the ubiquitin proteasome proteolytic pathway. Moreover, we identify several new pollen-specific candidate genes that might play a significant role in pollen biology. Conclusion: This is the first report of a soybean pollen transcriptional profile. These data extend our current knowledge regarding regulatory pathways that govern the gene regulation and development of pollen. We also demonstrate that pollen is a rich store of regulatory proteins that are essential and sufficient for de novo gene expression. A comparison between transcription factors up-regulated in soybean and those upregulated in Arabidopsis revealed some divergence in the numbers and kinds of regulatory proteins expressed in both species.
