How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

A RAD-seq phylogeny is presented for the genus Ulmus , and a revised infrageneric classification is given, with keys, descriptions, and range maps for the subgenera and sections. The previously accepted classification was based on a cpDNA phylogeny, but several well-marked clades in the chloroplast phylogeny are not recovered in the RAD-seq phyloge...
Premise of the study: Climate cycles of the Quaternary have impacted plants at a global scale, leaving behind a complex genetic legacy. Species of the northern Rocky Mountains of North America were exposed to more uniform glacial patterns than the central and southern ranges, where synergistic relationships between temperature and precipitation ca...
Premise of the study: Microsatellite primers were designed for Calochortus gunnisonii (Liliaceae), a montane lily species of the central and southern Rocky Mountains, using next-generation DNA sequencing. The markers will be used to investigate population structure, genetic diversity, and demographic history. Methods and Results: Thirteen polymorph...
Does anyone have any experience with flow cytometry on silica dried plant materials? I have tried a few batches of samples using PI default protocols with varied success. I assume there are many ways to modify this protocol and the literature has very few papers talking about this. Any suggestions would be much appreciated.
I am attempting to align some raw sequencing reads to a set of recently published, universal gene probes. I would like to be able to create a coding script that can be used for future species downstream. My goal is to see which raw reads align with genes from the set and use those for a trial sequencing run. I have recently used Bowtie to align to a genome, but it seems to me that reference sequence programs like Bowtie2 build indices from a whole genome fq file. Does anyone have any suggestions?

I'm struggling to find decent base maps of western North America for publication with QGIS. I'm relatively new to the program, but have some experience. Does anyone have a preference for a map that best shows geographic features and geopolitical boundaries, while still allowing clarity for population sampling localities (Lat/Long)?
So far I've used some basic tools in ggmap (R) but I would like to customize a bit more for my audience.
Thanks in advance.
