Phylogenetics benefits from using a large number of putatively independent nuclear loci and their combination with other sources of information, such as the plastid and mitochondrial genomes. To facilitate the selection of orthologous low-copy nuclear (LCN) loci for phylogenetics in nonmodel organisms, we created an automated and interactive script to select hundreds of LCN loci by a comparison...
An alarming loss of genetic variability of three Andean tubers (Ullucus tuberosus, ullucus; Oxalis tuberosa, oca; and, Tropaeolum tuberosum, mashua) has been observed during the last decades due to many factors such us the introduction of new varieties, droughts, changes in food habits, encroaching agriculture, deforestation and the migration from rural to urban areas. Thus, a pilot study was c...
Oxalic acid is widely distributed in plants. Although its concentration is not normally high, certain plants such as Oxalis sp., Begonia sp., rhubarb, and spinach contain large amounts of the acid. Cotyledons of spinach, for example, have been reported to contain up to 26% dry weight of oxalic acid (4). The only enzyme system previously reported to metabolize oxalate in plants is oxalate oxidas...
Phylogeographical patterns provide valuable insight into the historical processes underlying diversification, and may provide a better understanding of biodiversity, dispersal modes, diversification times, extinctions, refuge areas and other species-/population-level processes. Here, we examine the genetic structure of Oxalis laciniata, a representative of Oxalis, which is an important emerging...
Epigenetic changes are crucial for the generation of immunological memory. Failure to generate or maintain these changes will result in poor memory responses. Similarly, augmenting or stabilizing the correct epigenetic states offers a potential method of enhancing memory. Yet the transcription factors that regulate these processes are poorly defined. We find that the transcription factor Oct1 a...
