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.

LSU network hubs integrate abiotic and biotic stress responses via interaction with the superoxide dismutase FSD2
In natural environments, plants often experience different stresses simultaneously, and adverse abiotic conditions can weaken the plant immune system. Interactome mapping revealed that the LOW SULPHUR UPREGULATED (LSU) proteins are hubs in an Arabidopsis protein interaction network that are targeted by virulence effectors from evolutionarily diverse pathogens. Here we show that LSU proteins are up-regulated in several abiotic and biotic stress conditions, such as nutrient depletion or salt stress, by both transcriptional and post-translational mechanisms. Interference with LSU expression prevents chloroplastic reactive oxygen species (ROS) production and proper stomatal closure during sulphur stress. We demonstrate that LSU1 interacts with the chloroplastic superoxide dismutase FSD2 and stimulates its enzymatic activity in vivo and in vitro. Pseudomonas syringae Virulence effectors interfere with this interaction and preclude re-localization of LSU1 to chloroplasts. We demonstrate that reduced LSU levels cause a moderately enhanced disease susceptibility in plants exposed to abiotic stresses such as nutrient deficiency, high salinity, or heavy metal toxicity, whereas LSU1 overexpression confers significant disease resistance in several of these conditions. Our data suggest that the network hub LSU1 plays an important role in co-ordinating plant immune responses across a spectrum of abiotic stress conditions.
LSU family members and NBR1 are novel factors that contribute to homeostasis of catalases and peroxisomes in Arabidopsis thaliana
The short coiled-coil LSU (RESPONSE TO LOW SULFUR) proteins are linked to sulfur metabolism and have numerous protein partners. However, most of these partners lack direct links to sulfur metabolism, and the role of such interactions remains elusive. Here, we confirmed LSU binding to Arabidopsis catalase (CAT) and revealed that NBR1, a selective autophagy receptor, strongly interacts with LSU1 but not with CAT. Consequently, we observed the involvement of autophagy but not NBR1 in CAT removal. The lsu and nbr1 mutants differed from the wild-type plants in size and the number of yellow fluorescent protein (YFP)-CAT condensates, the number of peroxisomes, and photosynthetic pigments levels in the presence and absence of stress. We conclude that LSU family members and NBR1 contribute directly or indirectly to CAT and peroxisome homeostasis, and the overall fitness of plants. Our structural models of CAT–LSU complexes show at least two regions of interaction in CAT, one of which is at the N-terminus. Indeed, the N-terminally truncated variants of CAT2 and CAT3 interact more weakly with LSU1 than their full-length variants, but the extent of reduction is higher for CAT2, suggesting differences in recognition of CAT2 and CAT3 by LSU1.
An updated LSU database and pipeline for environmental DNA identification of arbuscular mycorrhizal fungi
Recent work established a backbone reference tree and phylogenetic placement pipeline for identification of arbuscular mycorrhizal fungal (AMF) large subunit (LSU) rDNA environmental sequences. Our previously published pipeline allowed any environmental sequence to be identified as putative AMF or within one of the major families. Despite this contribution, difficulties in implementation of the pipeline remain. Here, we present an updated database and pipeline with (1) an expanded backbone tree to include four newly described genera and (2) several changes to improve ease and consistency of implementation. In particular, packages required for the pipeline are now installed as a single folder (conda environment) and the pipeline has been tested across three university computing clusters. This updated backbone tree and pipeline will enable broadened adoption by the community, advancing our understanding of these ubiquitous and ecologically important fungi.
LSU Computational System Biology Gateway for Education
Science gateways are a mechanism for delivering scientific software as a service, especially when the software requires high performance computing (HPC) resources to run effectively. The existence of a science gateway eliminates the user's need to learn to work with HPC systems and to manage software installations and updates. With well-designed user interfaces, users can more quickly become effective users of scientific applications and can manage information needed for replicating, modifying, and sharing results. All of these efficiency gains enable users to focus more on their research. In addition, science gateways are being identified as an effective educational tool, a tool to be used in classroom environments as a method to get students quickly into research on domain specific questions. In the absence of a science gateway, students are likely to need a considerable time to learn to work with HPC systems, and any time spent on such will reduce their time on the actual science. This poster presents how the Louisiana State University (LSU) gateway for the Computational System Biology Group (CSBG) - (www.brylinski.org) was updated and improved to be a classroom teaching tool. This work makes extensive use of Apache Airavata's group management capabilities.

I'm not affiliated with LSU, but can I get a scan of a government document on microform?
Search Discovery for the title of the government document, which may provide a link to ERIC. If found and the ERIC number begins with ED, download it and provide the PDF and end the chat. If not found, send the patron this message: For federal and state government documents, LSU Libraries will scan microfilm and microfiche up to 50 pages, at no cost. The library will review the request for copyright compliance prior to providing. Please allow 2-3 business days for the scan. Then transfer the request to Interlibary Loan, or create a ticket for Interlibrary Loan. Answered by: Jacob Fontenot
What costs are associated with borrowing items from the library?
When borrowing materials from LSU Library, there are no costs or fees applied to any patron's account at the time of checkout. When items are not returned on time, overdue and lost fines can begin to accrue. Please keep track of your library due dates and make sure you review the borrowing policies below. In general, borrowing from the library is free until items are late, lost, damaged, or stolen. LSU Libraries | Borrowing<br>LSU Libraries | Loan Periods Answered by: Access Services Staff
Does the library hold popular fiction books?
The library does buy some popular fiction books, usually those deemed "essential" by GOBI, has won a prestigious prize, or is highly praised by the Times Literary Supplement or the NYT. Because we are an academic library, the books are shelved according to the Library of Congress classifcation scheme, meaning there is no one section for popular fiction books. If there are titles you are looking for, try searching the catalog (https://lsu.ent.sirsi.net/client/en_US/lsu/?rm=MORE+SEARCH+OP0%7C%7C%7C…) or speak with a librarian (https://www.lib.lsu.edu/staff?field_staff_type=2&amp;search_api_staff=&amp;fiel…) .

Do we have any resources for state licensing exams? (contractors, horticulture, plumbing, etc.?)
Our PrepSTEP (https://libezp.lib.lsu.edu/login?url=http://www.learningexpresslibrary3…) (formerly known as Learning Express Library) database is probably our best resource for this, though you may want to check with the agencies to ensure the materials are up to date. These materials are generally under the career preparation section on the PrepSTEP homepage. East Baton Rouge Public Library (https://www.ebrpl.com/) also has Learning Express 3.0 that has state test prep material if you have a current EBRPL card. Answered by: Electronic Resources
Are there restrictions on photography and filming inside the LSU Main Library?
While LSUs primary mission is education, LSU Libraries is available on a limited basis for other projects such as the filming of television shows, movies, commercials, and other media as long as it does not interfere with the Libraries primary educational mission and necessary day to day functions. LSU Libraries requires that all photography and/or filming taking place in LSU Library or Hill Memorial Library first adhere to the Film and Video Procedures policy (https://www.lsu.edu/administration/ofa/docs/FilmProceduresWebsite2017.p…) set down by LSUs Office of Finance and Administration. Additionally, projects such as these must be approved by LSU Libraries Director of Communications. If you need further clarification, please submit a ticket (https://askus.lib.lsu.edu/) .
