Seasonal abundance and diversity of potential Xylella (Xanthomonadales: xanthomonadaceae) vectoring leafhoppers in Mississippi muscadine vineyards
Pierce’s disease remains an important economic problem for producers of wine grapes, and while muscadine grapes do exhibit resistance, stressed or weakened vines can be more susceptible. Vector management may be a useful tool in limiting the pathogen spread within a vineyard, but knowledge of leafho...

Development of a targeted genotyping platform for reproducible results within tetraploid and hexaploid blueberry
Blueberry (Vaccinium spp.) is one of the most economically important berry crops in North America. Validation of genetic mapping studies is often hindered due to asynchronous marker technology. The development of a standardized genotyping platform that targets a specific set of polymorphic loci can ...

Genomic and transcriptomic comparisons of the twig blight pathogen, Passalora sequoiae with Mycosphaereallaceae foliar and conifer pathogens
Passalora sequoiae is a foliar pathogen to conifer tree species. In this study, we conducted whole genome and transcriptome analyses on isolates of P. sequoiae collected from symptomatic Leyland Cypress leaves from a Christmas tree farm in Mississippi. The objectives for this research were to elucid...

Long-read, chromosome-scale assembly of Vitis rotundifolia cv. Carlos and its unique resistance to Xylella fastidiosa subsp. fastidiosa
Muscadine grape (Vitis rotundifolia) is resistant to many of the pathogens that negatively impact the production of common grape (V. vinifera), including the bacterial pathogen Xylella fastidiosa, subsp. Fastidiosa (Xfsf), which causes Pierce’s Disease (PD). Previous studies in common grape have ind...

Combining high throughput phenotyping and multivariate analysis to assess fruit quality traits in southern highbush blueberry (V. corymbosum interspecific hybrids) germplasm collection
Breeding blueberry cultivars with enhanced fruit quality requires simple, accurate and cost-effective assays to select individuals from segregating populations. In this study, berry diameter, berry weight, firmness, pH, total polyphenol, total acids, D- glucose, D-fructose, total glucose, and total ...

VacCAP develops high throughput genotyping platforms for blueberry and cranberry
The Vaccinium Coordinated Agricultural Project (VacCAP) was funded in 2018 as a multi-institutional transdisciplinary project focused on advancing genomic resources and breeding tools for blueberry and cranberry, emphasizing fruit quality traits. One objective of the project is to leverage newly dev...

Assessment of the southern highbush blueberry (V. corymbosum interspecific hybrids) germplasm collection for fruit quality attributes
Breeding new blueberry cultivars with enhanced fruit quality requires simple, accurate and cost-effective assays to select individual from segregating population. In this study, berry diameter, berry weight, firmness, pH, total polyphenol, total acids, D- glucose, D-fructose, total glucose (sucrose)...

'USDA-Spiers' rabbiteye blueberry
U*SDA-Spiers’ is a new hexaploid blueberry (Vaccinium hybrid ) developed by the United States Department of Agriculture-Agricultural Research Service and resulted from crosses among diverse blueberry germplasm and species including V. virgatum (rabbiteye blueberry) with V. constablei, V. corymbosu...

Evaluation of one-time applications of foliar applied auxin co-applied with surfactant for use in commercial cutting propagation
Use of foliar auxin applications are increasing in the nursery and greenhouse industry.
However, previous research has shown that insufficient auxin is absorbed or translocated to the site of action when foliar auxin applications are used. It is theorized that adding surfactants to foliar applicatio...

VacCAP produces a targeted capture genotyping platform for blueberry
The Vaccinium coordinated agricultural project (VacCAP) was funded in 2019 as a multi-institutional transdisciplinary project focused on enabling marker-assisted selection in blueberry and cranberry, with an emphasis on fruit quality traits. The objective of this study is to use a community approach...

Genome-wide identification of loci associated with phenology-related traits and their adaptive variations in a highbush blueberry collection
Genetic variation in phenological traits is key to expanding production areas of crops. Southern highbush blueberry (SHB) is a blueberry cultivar group adapted to warmer climates and has been developed by multiple interspecific hybridizations between elite Northern highbush blueberry (NHB) (Vacciniu...

There and back again; historical perspective and future directions for Vaccinium breeding and research studies
The genus Vaccinium L. (Ericaceae) contains a wide diversity of culturally and economically important berry crop species. Blueberry (Vaccinium spp.) and cranberry (V. macrocarpon) have gained particular interest and consumption worldwide over their relatively short domestication history (~100 years)...

High-quality reference genome and annotation aids understanding of berry development for evergreen blueberry (Vaccinium darrowii)
Vaccinium darrowii Camp (2n=2x=24) is a native North American blueberry species and an important source of traits such as low chill requirement in commercial southern highbush blueberry breeding (V. corymbosum, 2n=4x=48). We present a chromosomal-level genome of V. darrowii generated by the combinat...

Identification of winter habit bread wheat landraces in the national small grains collection with resistance to emerging stem rust pathogen variants
Wheat stem rust caused by Puccinia graminis f. sp. tritici (Pgt) is a widespread and recurring threat to wheat production. Emerging Pgt variants are rapidly overcoming major gene resistance deployed in wheat cultivars and new sources of race-nonspecific resistance are urgently needed. The National S...

Micropropagation of Hibiscus moscheutos L. ‘Luna White’: Effect of growth regulators and explants on nuclear DNA content and ploidy stability of regenerants
Hibiscus moscheutos L., also known as hardy hibiscus, is valued for its medicinal and ornamental attributes. It is usually propagated via seeds or cuttings. The purpose of this investigation was to develop a dependable micropropagation for H. moscheutos ‘Luna White’. To that end, the effect of four...

Genomic insight into the developmental history of southern highbush blueberry populations
Interspecific hybridization is a common breeding approach for introducing novel traits and genetic diversity to breeding populations. Southern highbush blueberry (SHB) is a blueberry cultivar group that has been intensively bred over the last 60 years. Specifically, it was developed by multiple inte...
