The objectives of this study were to construct a high-density linkage map and to identify the underlying genetic basis of fruit quality traits in blueberry. A total of 287 F1individuals derived from a cross between two southern highbush blueberry cultivars, ‘Reveille’ and ‘Arlen’, were phenotyped over three years (2016–2018) for fruit quality-related traits, including titratable acidity, pH, total soluble solids, and fruit weight. A high-density linkage map was constructed using 17k single nucleotide polymorphisms markers. The linkage map spanned a total of 1397 cM with an average inter-loci distance of 0.08 cM. The quantitative trait loci interval mapping based on the hidden Markov model identified 18 loci for fruit quality traits, including seven loci for fruit weight, three loci for titratable acidity, five loci for pH, and three loci for total soluble solids. Ten of these loci were detected in more than one year. These loci explained phenotypic variance ranging from 7 to 28% for titratable acidity and total soluble solid, and 8–13% for pH. However, the loci identified for fruit weight did not explain more than 10% of the phenotypic variance. We also reported the association between fruit quality traits and metabolites detected by Proton nuclear magnetic resonance analysis directly responsible for these fruit quality traits. Organic acids, citric acid, and quinic acid were significantly (P < 0.05) and positively correlated with titratable acidity. Sugar molecules showed a strong and positive correlation with total soluble solids. Overall, the study dissected the genetic basis of fruit quality traits and established an association between these fruit quality traits and metabolites.}, number={1}, journal={HORTICULTURE RESEARCH}, author={Mengist, Molla F. and Bostan, Hamed and Young, Elisheba and Kay, Kristine L. and Gillitt, Nicholas and Ballington, James and Kay, Colin D. and Ferruzzi, Mario G. and Ashrafi, Hamid and Lila, Mary Ann and et al.}, year={2021}, month={Dec} } @misc{kay_strauch_granillo_bame_xiong_mast_burton-freeman_kay_lila_2022, title={The berry health tool chest - an evidence map and interactive resource}, volume={80}, ISSN={["1753-4887"]}, DOI={10.1093/nutrit/nuab011}, abstractNote={Abstract Berry consumption is linked to diverse health benefits, but numerous questions remain regarding mechanism of action, dose efficacy, and optimal duration and frequency of intake. Addressing these outstanding questions requires an organized assessment of current research, to inform future study designs and fill critical knowledge gaps. Tools that organize such information will also facilitate consumer messaging, targeted nutritional health initiatives, and dietary intake guidelines. This review aimed to describe the development and utility of the “Berry Health Tool Chest,” an evidence map summarizing trial design features of studies characterizing the impact of berry consumption upon human health biomarkers. A systematic search strategy identified relevant high-quality human feeding studies, whose study design parameters were collected and compiled into an evidence map that is freely available as an interactive online interface enabling tabulated data to be interrogated, filtered, and exported. Of the 231 included studies, approximately 70% were of less than 3 months’ duration and/or fewer than 50 participants, illustrating research gaps that could potentially inform the design of future studies.}, number={1}, journal={NUTRITION REVIEWS}, author={Kay, Kristine L. and Strauch, Renee C. and Granillo, Cheryl D. and Bame, Megan W. and Xiong, Jia and Mast, Aubrey C. and Burton-Freeman, Britt and Kay, Colin D. and Lila, Mary Ann}, year={2022}, month={Jan}, pages={68–77} } @article{nieman_gillitt_chen_zhang_sha_kay_chandra_kay_lila_2020, title={Blueberry and/or Banana Consumption Mitigate Arachidonic, Cytochrome P450 Oxylipin Generation During Recovery From 75-Km Cycling: A Randomized Trial}, volume={7}, ISSN={["2296-861X"]}, DOI={10.3389/fnut.2020.00121}, abstractNote={Oxylipins are bioactive lipid oxidation products, have vital regulatory roles in numerous physiological processes including inflammation, and can be impacted by diet. This study determined if 2-weeks of blueberry and/or acute banana ingestion influenced generation of n-6 and n-3 PUFA-derived oxylipins during recovery from exercise-induced physiological stress. Cyclists (n = 59, 39 ± 2 years of age) were randomized to freeze-dried blueberry or placebo groups, and ingested 26 grams/d (1 cup/d blueberries equivalent) for 2 weeks. Cyclists reported to the lab in an overnight fasted state and engaged in a 75-km cycling time trial (185.5 ± 5.2 min). Cyclists from each group (blueberry, placebo) were further randomized to ingestion of a water-only control or water with a carbohydrate source (Cavendish bananas, 0.2 g/kg carbohydrate every 15 min) during exercise. Blood samples were collected pre- and post-2-weeks blueberry supplementation, and 0, 1.5, 3, 5, 24, and 48 h-post-exercise. Plasma oxylipins and blueberry and banana metabolites were measured with UPLC–tandem MS/MS. Significant time by treatment effects (eight time points, four groups) were found for 24 blueberry- and seven banana-derived phenolic metabolites in plasma (FDR adjusted p < 0.05). Significant post-exercise increases were observed for 64 of 67 identified plasma oxylipins. When oxylipins were grouped relative to fatty acid substrate [arachidonic acid (ARA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), α-linolenic acid (ALA), linoleic acid (LA)], and enzyme systems [cytochrome P450 (CYP), lipoxygenase (LOX)], banana and blueberry ingestion were independently associated with significant post-exercise reductions in pro-inflammatory ARA-CYP hydroxy- and dihydroxy-eicosatetraenoic acids (HETEs, DiHETrEs) (treatment effects, FDR adjusted p < 0.05). These trial differences were especially apparent within the first 3 h of recovery. In summary, heavy exertion evoked a transient but robust increase in plasma levels of oxylipins in cyclists, with a strong attenuation effect linked to both chronic blueberry and acute banana intake on pro-inflammatory ARA-CYP oxylipins.}, journal={FRONTIERS IN NUTRITION}, author={Nieman, David C. and Gillitt, Nicholas D. and Chen, Guan-Yuan and Zhang, Qibin and Sha, Wei and Kay, Colin D. and Chandra, Preeti and Kay, Kristine L. and Lila, Mary Ann}, year={2020}, month={Aug} } @article{zhou_kay_hecht_moore_le brun_2018, title={The N-terminal domains of Bacillus subtilis CopA do not form a stable complex in the absence of their inter-domain linker}, volume={1866}, ISSN={["1878-1454"]}, DOI={10.1016/j.bbapap.2017.11.008}, abstractNote={Copper-transporting P-type ATPases, which play important roles in trafficking Cu(I) across membranes for the biogenesis of copper proteins or for copper detoxification, contain a variable number of soluble metal-binding domains at their N-termini. It is increasingly apparent that these play an important role in regulating copper transport in a Cu(I)-responsive manner, but how they do this is unknown. CopA, a Cu(I)-transporter from Bacillus subtilis, contains two N-terminal soluble domains that are closely packed, with inter-domain interactions at two principal regions. Here, we sought to determine the extent to which the domains interact in the absence of their inter-domain covalent linker, and how their Cu(I)-binding properties are affected. Studies of a 1:1 mixture of separate CopAa and CopAb domains showed that the domains do not form a stable complex, with only indirect evidence of a weak interaction between them. Their Cu(I)-binding behaviour was distinct from that of the two domain protein and consistent with a lack of interaction between the domains. Cu(I)-mediated protein association was observed, but this occurred only between domains of the same type. Thus, the inter-domain covalent link between CopAa and CopAb is essential for inter-domain interactions and for Cu(I)-binding behaviour.}, number={2}, journal={BIOCHIMICA ET BIOPHYSICA ACTA-PROTEINS AND PROTEOMICS}, author={Zhou, Liang and Kay, Kristine L. and Hecht, Oliver and Moore, Geoffrey R. and Le Brun, Nick E.}, year={2018}, month={Feb}, pages={275–282} }
