Project description:Analysis of gene expression data from four genetically diverse wild soybean accessions helps reveal both sensitive and resistant responses of the plants to increased ozone levels. Results help characterize genetic response of wild soybean to ozone stress and could help provide information on genetic resources for creating ozone-tolerant soybean breeding lines.

Project description:Phosphorus is one of the most important macronutrients that is required for plant growth and development. However, stress under low-P conditions has become a limiting factor that affects crop yields and qualities. Plants have developed strategies to cope with this, while few genes associated with low-P tolerance have been identified in soybean. We used microarrays to detail the global programme of gene expression under different phosphorus treatments of two soybean accessions CD and YH with different phosphorus efficiency.

Project description:Four selected soybean genotypes with varying degrees of quantitative resistance that were well-characterized were selected for this study. These included two resistant genotypes (V71-370, Conrad), and two susceptible genotypes (Sloan, and VP-RIL9). A P. sojae isolate, PT2004C2.S1 , which is virulent to the soybean genotypes carrying Rps1a, Rps1b, Rps1k, Rps2, Rps3a, Rps3c, Rps4, Rps5, Rps6, or Rps7, was used in this study. Keywords: Genotypic variation on quantitative resistance

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 aphid is one of the major limiting factors for soybean production. However, the mechanism for aphid resistance in soybean is remain enigmatic, very little information is available about the different mechanisms between antibiosis and antixenosis genotypes. Here we dissected aphid infestation into three stages and used genome-wide gene expression profiling to investigate the underlying aphid-plant interaction mechanisms. Approximately 990 million raw reads in total were obtained, the high expression correlation in each genotype between infestation and non-infestation indicated that the response to aphid was controlled by a small subset of important genes. Moreover, plant response to aphid infestation was more rapid in resistant genotypes. Among the differentially expressed genes (DEGs), a total of 901 transcription factor (TF) genes categorized to 40 families were identified with distinct expression patterns, of which AP2/ERF, MYB and WRKY families were proposed to playing dominated roles. Gene expression profiling demonstrated that these genes had either similar or distinct expression patterns in genotypes. Besides, JA-responsive pathway was domination in aphid-soybean interaction compared to SA pathway, which was not involved plant response to aphid in susceptible and antixenotic genotypes but played an important role in antibiosis one. Throughout, callose were deposited in all genotypes but it was more rapidly and efficiently in antibiotic one. However, reactive oxygen species were not involved in response to aphid attack in resistant genotypes during aphid infestation. Our study helps uncover important genes associated with aphid-attack response in antibiosis and antixenotic genotypes of soybean.

Project description:White mold disease, caused by Sclerotinia sclerotiorum (Lib) de Bary, can be a serious disease of crops grown under cool moist environments. In many plants, like soybean [Glycine max (L.) Merr.], complete genetic resistance does not exist. To identify possible genes involved in defense against this pathogen, and to determine possible physiological changes that occur during infection, a microarray screen was conducted using stem tissue to evaluate changes in gene expression between partially resistant and susceptible soybean genotypes at 8 and 14 hours post inoculation. RNA from 15 day old inoculated plants was labeled and hybridized to soybean cDNA microarrays. ANOVA identified 1270 significant genes from the comparison between time points and 105 genes from the comparison between genotypes. Selected genes were classified into functional categories. The analyses identified changes in cell-wall composition and signaling pathways, as well as suggesting a role for anthocyanin and anthocianidin synthesis in the defense against S. sclerotiorum. In-silico mapping of both the differentially expressed transcripts and of public markers associated with partial resistance to white mold, provided evidence of several differentially expressed genes being closely positioned to white mold resistance markers, with the two most promising genes encoding a PR-5 and anthocyanidin synthase.
