Project description:Salvia hispanica L. (chia) is a member of the mint family that is cultivated for its seeds. The majority of seed content in chia is comprised of omega fatty acids. Furthermore, chia seeds are also rich in fiber and minerals. The human health potential of chia seeds have driven studies of dietary effects, however there is little genetic or genomic studies available. In this study we obtained RNA from seeds, shoots, cotyledons, leaf primordia, nodes, racemes, and flower tissues from different developmental stages to generate an expression atlas for chia. RNA was sequenced on an Illumina Hiseq 2500. Sequence reads were assembled de novo to produce transcripts. Sequence reads were aligned to the chia transcriptome assembly to generate counts for each tissue type. Differentially expressed transcripts were determined for each tissue type.
Project description:Transcriptional profiling of Haloarcula hispanica wild-type strain cultured in different media comparing MG medium with 168 medium. H. hispanica wild-type strain can accumulate PHBV in MG medium, while can not in 168 medium. Goal was to explore the PHA biosynthesis and its impact on central metabolism in H. hispanica.
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: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. In order to generate the Salvia Subtracted Diversity Array (SDA), a Suppression Subtractive Hybridization (SSH) was performed between a pool of ten Salvia species and a pool of non-angiosperm and angiosperms (excluding the Lamiaceae) to selectively isolate Salvia-specific sequences. A total of 285 subtracted genomic DNA (gDNA) fragments were amplified and arrayed. DNA fingerprints were obtained for fifteen Salvia genotypes including three that were not part of the original subtraction pool. Hierarchical cluster analysis indicated that the Salvia-specific SDA was capable of differentiating closely related species of S. officinalis and S. miltiorrhiza and was also able to reveal genetic relationships consistent with geographical origins. Species-specific features were also found for S. elegans, S. officinalis, S. sclarea, S. przewalskii and S. runcinata.
