Evaluation Of Pierce’S Disease-Resistant Grapevine Cultivars In Upstate South Carolina, Annie Bruno

All Theses

Interest in wine grape production is increasing in South Carolina, but Pierce’s Disease (PD) caused by the xylem-limited bacteria Xylella fastidiosa (Xf) is a major limiting factor. Xf is spread by sap-sucking insect vectors in the Cicadellidae family such as sharpshooters. In the United States, Xf has become endemic to the southeast as global temperatures rise, causing winter temperatures to increase, which allows the bacteria to survive year-round. However, PD-resistant grapevine hybrid cultivars have become available through breeding V. vinifera genes with native American Vitis species that are resistant to Xf. In this study, the PD-resistant grapevine …

Disentangling Genotype And Environment Specific Latent Features For Improved Trait Prediction Using A Compositional Autoencoder, Anirudha Powadi, Talukder Zaki Jubery, Michael C. Tross, James C. Schnable, Baskar Ganapathysubramanian

Department of Agronomy and Horticulture: Faculty Publications

In plant breeding and genetics, predictive models traditionally rely on compact representations of high-dimensional data, often using methods like Principal Component Analysis (PCA) and, more recently, Autoencoders (AE). However, these methods do not separate genotype-specific and environment-specific features, limiting their ability to accurately predict traits influenced by both genetic and environmental factors. We hypothesize that disentangling these representations into genotype-specific and environment-specific components can enhance predictive models. To test this, we developed a compositional autoencoder (CAE) that decomposes high-dimensional data into distinct genotype-specific and environment-specific latent features. Our CAE framework employed a hierarchical architecture within an autoencoder to effectively separate …
