Metabolomic analysis combined with machine learning algorithms enables the evaluation of postharvest pecan color stability.

Nut kernel color is a crucial quality indicator affecting the consumers first impression of the product. While growing evidence suggests that plant phenolics and their derivatives are linked to nut kernel color, the compounds (biomarkers) responsible for kernel color stability during storage remain elusive. Here, pathway-based metabolomics with machine learning algorithms were employed to identify key metabolites of postharvest pecan color stability.

Standard Area Diagrams for Pecan Leaf Scab: Effect of Rater Experience, Location, and Leaf Size on Reliability and Accuracy of Visual Estimates.

Assessments of the severity of scab (), an economically significant disease of pecan, are critical for determining pecan cultivar susceptibility, disease epidemiology, and integrated disease management approaches. We developed a standard area diagram (SAD) set to aid in assessments of pecan leaflet scab. Leaflets with scab lesions were harvested and scanned using a flatbed scanner at 600 dpi, and Fiji (ImageJ) was used to determine the actual percent disease severity.

Influence of Geographical Orchard Location on the Microbiome from the Progeny of a Pecan Controlled Cross.

(Wangenh.) K.Koch production has expanded beyond the native distribution as the genetic diversity of the species, in part, has allowed the trees to grow under broad geographic and climatic ranges.

Glutathione S-transferase: a candidate gene for berry color in muscadine grapes (Vitis rotundifolia).

Muscadine grapes (Vitis rotundifolia Michx.) are a specialty crop cultivated in the southern United States. Muscadines (2n = 40) belong to the Muscadinia subgenus of Vitis, while other cultivated grape species belong to the subgenus Euvitis (2n = 38).

Four chromosome scale genomes and a pan-genome annotation to accelerate pecan tree breeding.

Genome-enabled biotechnologies have the potential to accelerate breeding efforts in long-lived perennial crop species. Despite the transformative potential of molecular tools in pecan and other outcrossing tree species, highly heterozygous genomes, significant presence-absence gene content variation, and histories of interspecific hybridization have constrained breeding efforts. To overcome these challenges, here, we present diploid genome assemblies and annotations of four outbred pecan genotypes, including a PacBio HiFi chromosome-scale assembly of both haplotypes of the 'Pawnee' cultivar.

High-density linkage maps and loci for berry color and flower sex in muscadine grape (Vitis rotundifolia).

Linkage maps of muscadine grape generated using genotyping-by-sequencing (GBS) provide insight into genome collinearity between Muscadinia and Euvitis subgenera and genetic control of flower sex and berry color. The muscadine grape, Vitis rotundifolia, is a specialty crop native to the southeastern USA. Muscadine vines can be male, female, or perfect-flowered, and berry color ranges from bronze to black.

Longitudinal and Cross-sectional Analyses of Lung Function in Toluene Diisocyanate Production Workers.

Objective: The aim of this study was to investigate lung function among toluene diisocyanate (TDI) production workers.

Methods: One hundred ninety-seven U.S workers performed spirometry from 2006 through 2012.

Incidence of Occupational Asthma and Exposure to Toluene Diisocyanate in the United States Toluene Diisocyanate Production Industry.

Objective: This study examines asthma risk in facilities producing toluene diisocyanate (TDI).

Methods: A total of 197 workers were monitored from 2007 to 2012. TDI air concentrations were used to estimate exposures.

Medical Monitoring for Occupational Asthma Among Toluene Diisocyanate Production Workers in the United States.

Objective: The aim of this study was to describe a study of medical monitoring methods and lessons learned in detecting health outcomes in U.S. plants producing toluene diisocyanate (TDI).

Cognitive function and patient-reported memory problems after radiotherapy for cancers at the skull base: A cross-sectional survivorship study using the Telephone Interview for Cognitive Status and the MD Anderson Symptom Inventory-Head and Neck Module.

Background: Using patient-reported and objective assessment tools, we sought to quantify cognitive symptoms and objective cognitive dysfunction in patients irradiated for skull base cancer.

Methods: Participants were assessed using the Telephone Interview for Cognitive Status (TICS) and the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN), with subsequent analysis.

Results: Of the 122 participants analyzed, the majority (63%) had no frank detectable cognitive impairment by TICS, with frank impairment in 6%.

Consumer Acceptability of Fresh-Market Muscadine Grapes.

The objective of this research was to investigate the acceptability of muscadine grape (Vitis rotundifolia) genotypes (cultivars and selections) and to correlate overall liking to other quality measurements to determine the main drivers of liking. Twenty-two genotypes grown at the Univ. of Georgia-Tifton Campus were evaluated.

Scab Susceptibility of a Provenance Collection of Pecan in Three Different Seasons in the Southeastern United States.

Pecan scab (caused by Fusicladium effusum) is the most economically destructive disease of pecan in the Southeast United States. Wet, humid conditions typical of the Southeast are known to provide conditions conducive to epidemics. A provenance collection of pecan from 19 locations representing the native range of the tree is located in Byron, Georgia, and was assessed for pecan scab severity in 1998, 2013, and 2014.

Developing a registry of workers involved in nanotechnology: BASF experiences.

Objective: To assist BASF in the establishment of a registry of workers involved in nanotechnology.

Methods: The initial step was a complete inventory of nanomaterials and sites of use. Guidance was developed to clarify which particulate nanomaterials were to be included in the survey.

Investigation of cancer occurrences associated with an herbicide manufacturing facility.

This study evaluated cancer incidence and mortality among 251 employees of a facility that synthesized a benzothiadiazin herbicide between 1979-1987. It was initiated in response to a perceived cancer cluster. Cancers were identified mainly by review of occupational medical records and personal interviews.

A first linkage map of pecan cultivars based on RAPD and AFLP markers.

We report here the first genetic linkage maps of pecan [Carya illinoinensis (Wangenh.) K. Koch], using random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers.

Experience with early detection of toluene diisocyanate-associated occupational asthma.

There is good reason to expect that regular respiratory surveillance and early removal of workers who develop toluene diisocyanate (TDI)-associated occupational asthma can effectively protect these workers from accelerated pulmonary function decline. Application of this simple principle in operating industrial workplaces presents numerous challenges. The experience of one corporation is presented.
