Project description:There is a need for expansion of the available potato genomic and transcriptomic resources in order to explore novel traits for potato improvement. Transcriptomic data derived from leaves from eleven native South American potato landraces (ten Peruvian and another; TBR Chilean) has been collected in order to aid the annotation of these genomes.
Project description:A population and admixture analysis of Mesoamerican Totonacs and South American Bolivians. A panel of highly informative ancestry informative markers (AIMs) for New World populations is identified. Regions coinciding with AIMs are have moderate signatures of selection. Population structure and differentiation were assessed with a genome-wide panel of 815,377 autosomal markers, Y-chromosome STR and SNPs, and mtDNA sequence data.
Project description:The Eurasian oystercatcher (Haematopus ostralegus), Near Threatened in the IUCN red list, was designated classified endangered species II by the Ministry of Environment of Korea and a Natural Monument (No. 326) by the Cultural Heritage Administration of Korea. In this study, the complete mitochondrial genome (16,798?bp) of H. ostralegus was determined for the first time, including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 non-coding region. The overall base composition was A (31.4%), C (31.3%), G (13.8%), and T (23.5%), so the percentage of A and T (54.9%) was slightly higher than that of G and C. A phylogenetic analysis using concatenated mitogenomes revealed that the family Haematopodidae has a closer relationship with the family Recurvirostridae and H. ostralegus and H. ater clustered together. The results are expected to provide useful resources for species identification and further phylogenetic studies of genus Haematopus.
Project description:Natural killer/T-cell lymphoma (NKTCL) is a malignant proliferation of CD56+/cytoCD3+ lymphocytes and constitutes a heterogeneous group of aggressive lymphomas prevalent in Asian and South American populations. Molecular pathogenesis of NKTCL remains largely elusive. Here we identified somatic mutations in RNA helicase gene DDX3X. Gene expression profiling revealed an association of DDX3X mutations with activation of NF-kB and MAPK pathways. Together, our work suggests the heterogeneity of gene mutational spectrum in NKTCL.

Project description:The species-specific identification of fibre origin is essential in archaeology but reveals challenging for closely related species. This is particularly true between the four South American Camelids (SAC) species: alpaca, guanaco, llama and vicuña. The analysis of proteins extracted from hairs and/or yarns by proteomics has emerged as a powerful method to differentiate between species. However, for SAC, the database information available is very poor, which limits this approach. In this study, we analysed 42 modern and 4 archaeological reference samples from the four SAC species.
