Project description:We selected 11 tissues from sorghum reference genome line BTX623 for comparative study between Maize and sorghum. These 11 tissues were selected at different development stages at Cold Spring Harbor Laboratory upland farm, RNA were extracted, library was made and sequenced on HiSeq2500 PE125 platform at Woodbury Genome Center.
Project description:Maize and sorghum are both important crops with similar overall plant architectures, but they have key differences, especially in regard to their inflorescences. To better understand these two organisms at the molecular level, we compared the expression profiles of both protein-coding and non-coding transcripts in 11 matched tissues using single-molecule long-read and deep RNA sequencing. In this study, maize B73 line was planted at Cold Spring Harbor Laboratory upland farm, 11 tissues together with previously reported six tissues were collected, RNA was extracted, library was made and sequenced on the HiSeq 2500 PE125 platform at Woodbury Genome Center.
Project description:To understand the role of GCN2 in stress response, the total transcript and translation state were compared between Arabidopsis thaliana wild type (ecotype Landsberg erecta) and gcn2 (Genetrap line GT8359, Cold Spring Harbor Laboratory) seedlings with or without herbicide chlorosufuron treatment RNA was fractionated using sucrose gradients into polysomal and nonpolysomal RNAs. We also determined overall total transcript levels. We used Affymetrix ATH1 microarrays.

Project description:BackgroundTransposable elements (TEs) are a major component of metazoan genomes and are associated with a variety of mechanisms that shape genome architecture and evolution. Despite the ever-growing number of insect genomes sequenced to date, our understanding of the diversity and evolution of insect TEs remains poor.ResultsHere, we present a standardized characterization and an order-level comparison of arthropod TE repertoires, encompassing 62 insect and 11 outgroup species. The insect TE repertoire contains TEs of almost every class previously described, and in some cases even TEs previously reported only from vertebrates and plants. Additionally, we identified a large fraction of unclassifiable TEs. We found high variation in TE content, ranging from less than 6% in the antarctic midge (Diptera), the honey bee and the turnip sawfly (Hymenoptera) to more than 58% in the malaria mosquito (Diptera) and the migratory locust (Orthoptera), and a possible relationship between the content and diversity of TEs and the genome size.ConclusionWhile most insect orders exhibit a characteristic TE composition, we also observed intraordinal differences, e.g., in Diptera, Hymenoptera, and Hemiptera. Our findings shed light on common patterns and reveal lineage-specific differences in content and evolution of TEs in insects. We anticipate our study to provide the basis for future comparative research on the insect TE repertoire.
