Integrating a historical and botanical work into modern collections and public platforms: The Flora of Forfarshire.
William Gardiner (1809-1852) spent his life in the Dundee region of Scotland. He was born into a humble family and received a basic education, but his passion for botany and exploration brought him recognition from other botanists including William Jackson Hooker. His collections became popular among benefactors and botanical societies, who paid him for volumes of dried plants illustrative of the Scottish Flora. One of his most important works is The Flora of Forfarshire (Scotland), published in 1848, which comprises an annotated catalog of plants documented during his years of traveling the local countryside. The book is one of the most detailed snapshots of plant diversity in a local area in the mid-1840s. In order to help fund his field work and the publication of the book, Gardiner produced a limited number of supplementary volumes containing pressed specimens of selected species. One of the remaining copies of this plant folio is accessioned at the University of Texas Libraries. Given the historical and botanical value of this work, The UT Plant Resources Center initiated a project with the main goal of making it available to the scientific community and the public. This project also provides a student enrichment opportunity through the new Museum Studies Certification Program. The project consists of four main components:
1. Digitizing the book and the accompanying specimen folio.
2. Updating the botanical nomenclature and checking and correcting possible botanical misidentifications in the accompanying volume.
3. Introducing the updated information and the images into the herbarium database.
4. Making the book and botanical information available online through the Texas Scholar Works repository through the University of Texas Libraries.
The supplementary volume contains specimens and information on 59 species of angiosperms, 17 ferns and allies, 37 bryophytes, 11 algae, and 10 lichens, collected at 36 total localities in Forfarshire (Forfar, or Angus, County) in Scotland. We have generated digital images of each page, and high quality prints with barcodes for each species. These data and links to image files are included in a database. To accomplish the last stage of the project, the images and a series of metadata that include collector, locality, date, and plant name will be compiled and uploaded to the Texas Scholar Works repository. A link to the images and the information will also be included in the Plant Resources Center herbarium website.Integrative Biolog
PRH/Hex: an oligomeric transcription factor and ,ultifunctional regulator of cell fate.
The PRH (proline-rich homeodomain) [also known as Hex (haematopoietically expressed homeobox)] protein is a critical regulator of vertebrate development. PRH is able to regulate cell proliferation and differentiation and is required for the formation of the vertebrate body axis, the haematopoietic and vascular systems and the formation of many vital organs. PRH is a DNAbinding protein that can repress and activate the transcription of its target genes using multiple mechanisms. In addition, PRH can regulate the nuclear transport of specific mRNAs making PRH a member of a select group of proteins that control gene expression at the transcriptional and translational levels. Recent biophysical analysis of the PRH protein has shown that it forms homo-oligomeric complexes in vivo and in vitro and that the proline-rich region of PRH forms a novel dimerization interface. Here we will review the current literature on PRH and discuss the complex web of interactions centred on this multifunctional protein
