Project description:We performed transcriptional profiling of sexed whole adults and mixed sex embryos of eight Drosophila species. These data were used in a comparative transcriptomics analysis of multiple Drosophila species to define functional elements conserved throughout the Drosophila genus.
Project description:The genus Helianthemum, commonly known as rockroses, encompasses 140 species primarily distributed in the Palearctic region, with notable diversification driven by climatic and geological changes. These plants are valuable for studying speciation processes and ecological divergence. The chemical properties of the leaves have also been investigated for containing valuable bioactive compounds with several therapeutic properties. However, the availability of genomic resources for species in this genus are almost entirely lacking. Here, we assembled and annotated the first reference transcriptome of Helianthemum marifolium, a species with wide morphological variability and infraspecific diversity. Illumina paired-end RNA sequences were generated using leaves from 16 individuals, representing the four recognized subspecies, all cultivated in a greenhouse. RNA reads were assembled with Trinity and Oases, and EvidentialGene produced a transcriptome with 122,002 transcripts. The transcriptome showed 59524 hits on the UniProtBK database through BLASTx. This transcriptome will be an invaluable resource for transcriptome-level population studies, conservation genetics of the many endangered species within the genus, and for deepen into the metabolic pathways of leaf-derived compounds.
Project description:Whole transcriptome RNA sequencing in brain tissue was generated to explore differences between young and old animals of two closely related species of deer mice (genus Peromyscus) that reportedly differ in their lifespans: P. leucopus that lives for up to 8 years and P. maniculatus that exhibits a lifespan of about 4 years.
Project description:Salvia is an important genus from the Lamiaceae with approximately 1000 species distributed globally. Several Salvia species are commercially important because of their medicinal and culinary properties. We report the construction of the first fingerprinting array for Salvia species enriched with polymorphic and divergent DNA sequences and demonstrate the potential of this array for fingerprinting several economically important members of this genus.
Project description:The Xenopus genus is well known for the high degree of polyploidy observed in its constituent species, but there is minimal information about transcriptional changes observed in these highly polyploid vertebrates. Xenopus andrei, an octoploid species within the Xenopus genus, presents a novel system for assessing a polyploid transcriptome during vertebrate development. RNA-Seq data was generated at nine different developmental stages ranging from unfertilized eggs through late tailbud stages. Additionally, using Trinity, RNA-seq data from all nine stages was pooled to create a draft de novo assembly of the transcriptome. This represents the first published assembly of an octoploid vertebrate transcriptome. This RNA-Seq and transcriptome data will be useful in comparing polyploid transcriptomes across Xenopus species, as well as understanding evolutionary implications of whole-genome duplication in vertebrates.
