Project description:To understand the genetic mechanisms involved in the functional transition of cotyledons from non-photosynthetic storage tissue to metabolically active photosynthetic tissue during soybean seedling development, we constructed seven different RNA-Seq libraries using cotyledons from each developmental stage separately. Analysis of RNA-Seq data from different developmental stages revealed the differential expression of many genes including transcription factors. In this study, we focused on NAC and YABBY transcription factors which showed a conspicuous expression pattern during soybean seedling development. Their expression gradually increases from stage 1 to stage 4 of soybean germinating cotyledons. The highest level of expression was found at stage 4. Then it gradually decreased as the germinating cotyledons develop a mature seedling. We investigated the differential expression of NAC and YABBY regulated genes between stage 3 (before the functional transition) and stage 6 (after the functional transition) using our RNA-Seq data. Based on our RNA-Seq data, we found that 10 genes are up-regulated and 21 genes are down-regulated by NAC transcription factor. Similarly we found that 19 genes are up-regulated and 27 genes are down-regulated by YABBY transcription factor. High-throughput sequencing using Illumina HiSeq 2000 (RNA-Seq) was performed on seven developmental stages of soybean seedlings, with two biological replicates per stage.
Project description:This series contain all stages Arabidopsis plant development. Stages of development includes unfertilized ovule, 24-Hr post-fertilization seed, globular stage seed, cotyledon stage seed, mature green seed, post-mature green seed, post-germination seedling, rosette leaf, root, stem, and floral bud.
Project description:Light, as both energy source and informational signal, profoundly influences plant growth and development during the whole life span from seed germination to flowering. To dissect the role for red light signaling in regulate the seedling development, we analyzed the gene expression profile of red light- and dark-grown WT seedlings by high throughput sequencing.
Project description:Transcriptome analysis of root development related genes in terrestrial and hydroponic ramie. Ramie seedlings were cultivated in soil, and in hydroponic with the shoot-cutting propagation method. The root samples from hydrophonic ramie were collected from the early stage (5-day-old seedling) and the late stage (30-day-old seedling) of acquatic roots induction. The roots of ramie seedling cultivated in soil were also collected for comparative analysis. Our study represents the detailed analysis of ramie root transcriptomes with biologic replicates.

Project description:Recent advances in high throughput sequencing methodologies allow the opportunity to probe in depth the transcriptomes of organisms including N. caninum. In this project, we are using Illumina sequencing technology to analyze the transcriptome (RNA-Seq) of experimentally accessible stages (e.g. tachyzoites at different times points) of N. caninum NCLiv. The aim is to make transcriptional landscape maps at different time points at different life cycle stages of N. caninum and compare it with equivalent datasets from the closely related parasite Toxoplasma gondii.

Project description:Transcription profiling of chicken development The experiment were perfomed as a part of our Vertebrate Evo-Devo project. The aim of the project is to compare transcription profiles of normal (unmanipulated, wild-type, whole embryo) vertebrate embryos. Total RNA was collected from wild type G.gallus whole embryos at 15 different stages (Stages:HH1,2,4,6,8,9,11,14,16,19,24,27,32,34,38), and hybridized to the Affymetrix Chicken Genome Array. All the stages contains data from two biological replications. Each staged-samples consists of pooled total RNA from several whole embryos.
