Project description:Transcriptome expression analysis in peanut to date has been limited to a relatively small set of genes and only recently have moderately significant number of ESTs has been released into the public domain. Utilization of these ESTs for the oligonucleotide microarrays provides a means to investigate large-scale transcript responses to a variety of developmental and environmental signals, ultimately improving our understanding of plant biology. We have developed a high-density oligonucleotide microarray for peanut using approximately 47,767 publicly available ESTs and tested the utility of this array for expression profiling in a variety of peanut tissues. To identify putatively tissue-specific genes and investigate the utility of this array, we compared transcript levels in pod to peg, leaf, stem, and root tissues. Results from this experiment showed a number of putatively pod-specific/abundant genes, as well as transcripts whose expression was low or undetected in pod compared to either peg, leaf, or stem. Keywords: Peanut tissue-specific gene expression We used Agilent peanut gene chips (017430) to identify putative tissue-specific genes and investigate the utility of the array for expression profiling of various peanut tissues. Pod, leaf, stem, peg and root tissues of the peanut genotype Flavrunner 458 were used in the study. Field grown plants under normal irrigation were used for sample collection. Three replications of microarray experiments were carried out by hybridizing the cRNA from pod tissue and cRNA from leaf, stem, peg and root tissues on the same dual color oligonucleotide arrays.

Project description:Comparison of gene expression profiles of widespread peanut cultivars for exploring the expression data in pod and leaf with regard to signatures of artificial selection We investigated the overall expression by hybridizing the microarray (GPL13178) with RNA samples from pods and leaves of five selected representative peanut varieties (Fuhuasheng, Shitouqi, Yueyou116, Shanyou523, and Yueyou7), which were widely cultivated in different periods of the past fifty years in southern China. We used the RNA sample from Yueyou7 pod as a reference for all the pod hybridizations, and used the Yueyou7 leaf sample as a reference for all the leaf hybridizations. Field grown plants under normal irrigation were used for sample collection. Replicates with dye-swap were performed for each genotype.

Project description:Seed expansion in peanut is a complex biological process involving many gene regulatory pathways. MicroRNAs (miRNAs) play important regulatory roles in plant growth and development, but little is known about their functions during seed expansion, or how they contribute to seed expansion in different peanut lines. We examined seed miRNA expression patterns at 15 and 35 days after flowering ( DAF ) in two peanut 8th generation recombinant inbred lines (RIL8); 8106, a medium-pod variety, and 8107, a super-pod variety. Using high-throughput sequencing, we identified 1082 miRNAs in developing peanut seeds including 434 novel miRNAs. We identified 316 differentially expressed miRNAs by comparing expression levels between the two peanut lines. Interestingly, 24 miRNAs showed contrasting patterns of expression in the two RILs, and 149 miRNAs were expressed predominantly in only one RIL at 35 DAF. Also, potential target genes for some conserved and novel miRNAs were identified by degradome sequencing; target genes were predicted to be involved in auxin mediated signaling pathways and cell division. We validated the expression patterns of some representative miRNAs and 12 target genes by qPCR, and found negative correlations between the expression level of miRNAs and their targets. miR156e, miR159b, miR160a, miR164a, miR166b, miR168a, miR171n, miR172c-5p, and miR319d and their corresponding target genes may play key roles in seed expansion in peanut. The results of our study also provide novel insights into the dynamic changes in miRNAs that occur during peanut seed development, and increase our understanding of miRNA function in seed expansion.

Project description:Food allergy affects an estimated 8% of children in the US, with increasing severity and global prevalence. Using single-cell RNA sequencing and paired TCR sequencing, we assessed the transcriptomes of CD154+ and CD137+ peanut-reactive T helper cells from 12 peanut-allergic patients longitudinally throughout peanut oral immunotherapy. These results demonstrate a differential response to OIT among subsets of peanut-reactive T helper cells, and indicate that non-Th2 activation signatures may be associated with clinical outcomes.

Project description:Peanut-responsive T cells from peanut allergic subjects were identified and selected based on CD154 expression after stimulation of peripheral blood mononuclear cells with crude peanut extract for 18h. As controls, polyclonally activated CD4+ T cells from peanut allergic subjects were selected. Additional controls included CD4+CD25+CD127- Tregs from peanut allergic or healthy controls. Single cells were obtained using the C1 system from Fluidigm, and a barcoded library constructed. Sequencing (Illumina) was performed using 100 nt paired end reads. Data on a total of 431 cells was available. The goal of the study was to understand the heterogeneity of the peanut-specific T cell response.

Project description:Cultivated peanut (Arachis hypogaea. L) is one of the most important oil crops in the world. After flowering, the peanut plant forms aboveground pegs (gynophores) that penetrate the soil, giving rise to underground pods. This means of reproduction, referred to as geocarpy, distinguishes peanuts from most other plants. The molecular mechanism underlying geocarpic pod development in peanut is poorly understood. To gain insight into the mechanism of geocarpy, we extracted proteins from aerial gynophores, subterranean unswollen gynophores, and gynophores that had just started to swell into pods. We analyzed the protein profiles in each of these samples by combining 1 DE with nanoLC-MS/MS approaches. In total, 2766, 2518, and 2280 proteins were identified from the three samples, respectively. An integrated analysis of proteome and transcriptome data revealed specifically or differentially expressed genes in the different developmental stages at both the mRNA and protein levels. A total of 69 proteins involved in the gravity response, light and mechanical stimulus, hormone biosynthesis, and transport were identified as being involved in geocarpy. Furthermore, we identified 91 genes that were specifically or abundantly expressed in aerial gynophores, including pectin methylesterase and expansin, which were presumed to promote the elongation of aerial gynophores. In addition, we identified 35 proteins involved in metabolism, defense, hormone biosynthesis and signal transduction, nitrogen fixation, and transport that accumulated in subterranean unswellen gynophores. Furthermore, 26 specific or highly abundant proteins related to fatty acid metabolism, starch synthesis, and lignin synthesis were identified in the early swelling pods. We identified thousands of proteins in the aerial gynophores, subterranean gynophores, and early swelling pods of peanut. This study provides the basis for examining the molecular mechanisms underlying peanut geocarpy pod development.
