Bento Search

Search all of LSU Libraries in one place. This includes the catalog, research guides, scholarly repository, website, etc.

What does bento search?

Bento searches all of the available resources at LSU Libraries. Please note that while Discovery does include Catalog results, the dedicated Catalog search can still be accessed.

Discovery
Searches our local print and electronic materials including e-books, journal articles, peer-reviewed articles, news, and magazines.
Research Guides
Searches the full-text of research guides published by LSU Libraries. A research guide is a curated, librarian‑built document that pulls together the most important resources for a topic, course, or assignment. It’s designed to help students, faculty, and researchers quickly find high‑quality, relevant information without having to sift through everything on their own.
Scholarly Repository
Searches the full-text of the Scholarly Repository. The LSU Scholarly Repository collects, preserves, publishes, and makes openly accessible the research and scholarship contributed by LSU faculty, staff, students, and units. Research and scholarly archived materials can include articles, monographs, books, theses & dissertations, audio-visual presentations, working papers, technical reports, conference proceedings, special collections, data, and publicly funded research.

Species delimitation in downy mildews: the case of Hyaloperonospora in the light of nuclear ribosomal ITS and LSU sequences
Species definitions for plant pathogens have considerable practical impact for measures such as plant protection or biological control, and are also important for comparative studies involving model organisms. However, in many groups, the delimitation of species is a notoriously difficult taxonomic problem. This is particularly evident in the obligate biotrophic downy mildew genera ( Peronosporaceae, Peronosporales, Oomycetes), which display a considerable diversity with respect to genetic distances and host plants, but are, for the most part, morphologically rather uniform. The recently established genus Hyaloperonospora is of particular biological interest because it shows an impressive radiation on virtually a single host family, Brassicaceae, and it contains the downy mildew parasite, Arabidopsis thaliana, of importance as a model organism. Based on the most comprehensive molecular sampling of specimens from a downy mildew genus to date, including various collections from different host species and geographic locations, we investigate the phylogenetic relationships of Hyaloperonospora by molecular analysis of the nuclear ribosomal ITS and LSU sequences. Phylogenetic trees were inferred with ML and MP from the combined dataset; partitioned Bremer support (PBrS) was used to assess potential conflict between data partitions. As in other downy mildew groups, the molecular data clearly corroborate earlier results that supported the use of narrow species delimitations and host ranges as taxonomic markers. With few exceptions, suggested species boundaries are supported without conflict between different data partitions. The results indicate that a combination of molecular and host features is a reliable means to discriminate downy mildew species for which morphological differences are unknown.
