(2016-05-18)
Black bear (Ursus americanus) abundance and distribution has declined drastically across the southeastern United States, where a range reduction of 80% has occurred. In this study, the structure, diversity, and connectivity ...
Genetic Technologies for Disease Resistance Research and Enhancement in Catfish
(2016-12-09)
A microinjection protocol was developed and validated for CRISPR/Cas9 gene editing in channel catfish, Ictalurus punctatus. This protocol proved to be rapid, efficient and does not require elaborate equipment or a high ...
Genetic Technologies for Growth Enhancement in Catfish
(2021-04-19)
The effects of CRISPR/Cas9 knockout of the myostatin (MSTN) gene in channel catfish, Ictalurus punctatus, was investigated. A total of 209 fish survived microinjection over 3 years with an average mutation rate of 58%. ...
Genome Wide Association Study (GWAS) on Root-Knot Nematode Resistance in Cultivated Peanut
(2019-07-16)
The peanut root-knot nematode, Meloidogyne arenaria, is one of the major soil-borne pests for peanut (Arachis hypogaea L.). It causes economic losses in the production of peanut in the southeastern region, especially in ...
Genome-wide association studies for columnaris resistance and morphology in hybrid catfish
(2016-03-03)
Catfish is the primary aquaculture species in the United States. Recently, the catfish industry in the USA has encountered unprecedented challenges due to increasing feed and energy costs, devastating diseases, and severe ...
Genome-Wide Associations Identifying Marker-Trait-Associations for Root Morphology and Photosynthetic Related Traits in a Soybean (Glycine max) Diversity Panel
(2023-04-26)
Soybean is a staple crop for the food, feed, and fuel industries because of its unique oil and protein composition. It is the second most produced crop globally, with average acres planted and harvest yield increasing ...
Genome-wide Characterization of Heat Shock Proteins in Channel Catfish (Ictalurus punctatus) and Determination of Their Involvement in Diseases
(2014-11-24)
Heat shock proteins (HSPs) consist of a large group of chaperones whose expression is induced by a number of stresses such as exposures to high temperature, hypoxia and infection.
In this study, I identified a total of ...
Genome-wide comparative analysis of channel catfish (Ictalurus punctatus)
(2013-04-22)
Comparative map is a powerful tool to transfer the genomic information from well-studied model species to non-model species whose genomic resources are limited. Channel catfish is a primary aquaculture species in United ...
