Project description:Brassinosteroids (BRs) are a series of sterol hormones in plants, which play important physiological roles in many aspects of plant growth and development processes. Exogenous application of BR and its inhibitors PPZ to investigated the roles of BR in soybean root growth and development. Transcriptome sequencing analysis was performed to identified lots number of differential expression genes(DEGs) by eBL (2,4-epicastasterone, 24-epiCS) and PPZ (propiconazole) treatment of soybean root tips(1 cm).

Project description:Cytosine methylation is an important mechanism for dynamical regulation of gene expression and transposon mobility during plant developmental processes. Recently, the variation of DNA methylation has been described between wild type and DNA methylation-related mutants in Arabidopsis thaliana. However, the elaborate representation of soybean DNA methylomes remains lacking. Here, we described the epigenome maps of soybean root, stem, leaf, and cotyledon of developing seed at a single-base resolution. We confirmed the transcription start sites of genes using high-throughput sequencing and reported the DNA methylation patterns in gene and transposon regions. The correlation between gene expression and DNA methylation was revealed through transcriptome sequencing. We found CHH methylation may function in promotion of gene expression and ten cotyledon-preferred genes were identified CHH hypermethylated in cotyledon. Small RNA library sequencing showed that DNA methylation was enhanced by small RNAs not by strand-specific way, and the variation of DNA methylation between the organs was highly related with expression of small RNAs. methylomes of roots, stems, leaves, and cotyledons of developing seeds

Project description:As an important adaptation to drought stress, several agronomic species, such as soybean and maize, can maintain the primary root substantial elongation rates at low water potentials, whereas shoot growth stops completely. In soybean, kinematic characterization of the spatial patterns of cell expansion within the root elongation zone showed that at low water potentials, elongation rates were preferentially maintained toward the root apex but were progressively inhibited at more basal locations, resulting in a shortened growth zone. To explore the molecular mechanism of root elongation in response to water stress, we set out to examine the expression of soybean genes in different root regions after 5 hours (5h) and 48 hours (48h) water stress treatment using the Affymetrix Soybean GeneChip containing 37,500 G. max probe sets.

Project description:Soybean root hair transcriptional response to their inoculation by the symbiotic bacteria B. japonicum involved in soybean nodulation. We used the first generation of an Affymetrix microarray to quantify the abundance of the transcripts from soybean root hair cells inoculated and mock-inoculated by B. japonicum. This experiment was performed on a time-course from 6 to 48 hours after inoculation.

Project description:Expression data from B. japonicum soybean root nodules including a nodulation time-course experiment with soybean nodules harvested at 10, 13, 21 and 31 dpi and transcriptome of bacteroids formed by a mutant defective in the RNA polymerase transcription factor sigma 54. Two reference data sets were established using B. japonicum cells grown in PSY medium under either aerobic or micro-aerobic conditions. Keywords: genetic modification, time course, growth conditions

Project description:we used soybean genome chips to investigate the expression pattern of about 37,500 unique ESTs locating on soybean Affymetrix chips (Affymetrix Inc.). KEYWORDS: Tissue comparison we compared soybean root meristem samples with non-meristematic tissues in 10 days old vegetative stage seedlings to define a unique set of root meristem enriched genes.

Project description:Soybean root hair transcriptional response to their inoculation by the symbiotic bacteria B. japonicum involved in soybean nodulation. We used the first generation of an Affymetrix microarray to quantify the abundance of the transcripts from soybean root hair cells inoculated and mock-inoculated by B. japonicum. This experiment was performed on a time-course from 6 to 48 hours after inoculation. Soybean seeds were sowed on sterile agar medium and grown for 3 days in a growth chamber before being treated with H2O (mock-inoculated) or B. japonicum (inoculated). Soybean root hair cells were isolated at different time points (6hr, 12hr, 18hr, 24hr, 36hr, 48hr) after treatment. For each time point and condition, 3 or 4 independent biological replicates were produced.
