The Research Projects Database (RPD) provides current food safety research projects from both U.S. and international government, and non-government organizations.
TIFF and JPEG files for the photographs used in constructing figures and supplemental figures in the manuscript, "ELIGULUM-A regulates lateral branch and leaf development," submitted to Plant Physiology. The images document a mutation that alters most of the structures of the plant and how the ELIGULUM-A gene interacts with different developmental pathways. The Figure Legend files describe the images individually.
Vaccination Against Lawsonia intracellularis Decreases Shedding of Salmonella enterica serovar Typhimurium in Co-Infected Pigs and Alters the Gut Microbiome
Salmonella enterica is a leading cause of foodborne illness worldwide and pork can serve a source of infection. In this study, we investigated if vaccinating pigs against Lawsonia intracellularis, a common pathogen of swine that has previously been shown to favor Salmonella enterica infection, confers protection against Salmonella enterica serovar Typhimurium. We investigated the underlying changes in the gut microbiome mediated by single S. Typhiumurium infection compared to co-infection with L. intracellularis as well as the effect of vaccination on the microbiome.
Leaf-level trade-offs between drought avoidance and desiccation recovery drive elevation stratification in arid oaks: site environmental data, individual tree stem and leaf physiological data, and analyses
We investigated whether oak species in the Chiricahua Mountains were 1) elevationally stratified, 2) whether that stratification was correlated with temperature minima, maxima, and water availability, 3) if physiological tolerances to freezing or drought stress correlated with elevation ranges, and 4) if traits important to local (elevation) distributions were correlated with climatic values of the wider species ranges. Data were collected at field sites from wild, adult trees in the Chiricahua Mountains, Arizona, USA from 2014-2015.
As the organic forage-finished beef industry continues to grow, it is important to understand factors that affect meat quality, characteristics of beef that influence human health, and sensory attributes of cooked beef. Research on alternative breeds and forage types that influence meat quality, FA and AA profiles, and sensory attributes in an organic forage-finished production system, as well as comparisons with alternative breeds is lacking. Data release is part of data management plan with USDA-NIFA funding. Data is from organic dairy beef steers collected at the West Central Research and Outreach Center, Morris, MN.
These risk maps for economically and ecologically important invasive species provide land managers with information to assess the potential for species introduction, establishment, and landscape susceptibility.
Non-native bark and ambrosia beetles are a serious threat to our nation’s urban and rural forests. In 2007, Forest Health Protection began implementation of an early detection and rapid response project for non-native bark and ambrosia beetles. An Early Detection and Rapid Response (EDRR) Team (consisting of Forest Service, APHIS, university and state representatives) has developed a framework for implementing a national, interagency detection, monitoring, and response system for these insects. This framework involves the cooperation of state partners, regional taxonomists and regional Forest Service staff. Participating states will be responsible for following project protocols with funding from the Forest Service.
