Kuntze] is a warm-season, perennial turfgrass species well adapted for home lawns and commercial landscapes with economic and ecological value. However, a lack of genomic resources in St. Augustinegrass has hindered the full utilization of genetic variance for maximizing genetic gain and limited our understanding of the species' evolution.In this study, we constructed the first high-density linkage map for St. Augustinegrass using a genotyping by sequencing (GBS) approach. The integrated linkage map consists of 2871 single nucleotide polymorphism (SNP) and 81 simple sequence repeat (SSR) markers, spanning 1241.7 cM, with an average distance of 0.4 cM between markers, and thus represents the densest genetic map for St. Augustinegrass to date. Comparative genomic analysis revealed inter-chromosome arrangements and independent nested chromosome fusion events that occurred after St. Augustinegrass, foxtail millet, sorghum, and rice diverged from a common ancestor. Forty-eight candidate quantitative trait loci (QTL) were detected for turf quality-related traits, including overall turf quality, leaf texture, genetic color, and turf density. Three hot spot regions were identified on linkage groups LG3 and LG8, where multi-QTL for different traits overlapped. Several leaf development related genes were contained within these identified QTL regions.This study developed the first high-density genetic map and identified putative QTL related to turf quality, which provide valuable genetic resources for marker-assisted selection (MAS) in St. Augustinegrass.}, number={1}, journal={BMC Plant Biology}, publisher={Springer Nature}, author={Yu, X. and Kimball, J.A. and Milla-Lewis, S.R.}, year={2018}, month={Nov}, pages={346} } @article{kimball_tuong_arellano_livingston_milla-lewis_2018, title={Linkage analysis and identification of quantitative trait loci associated with freeze tolerance and turf quality traits in St. Augustinegrass}, volume={38}, ISSN={1380-3743, 1572-9788}, url={http://link.springer.com/10.1007/s11032-018-0817-y}, DOI={10.1007/s11032-018-0817-y}, number={5}, journal={Molecular Breeding}, publisher={Springer Nature}, author={Kimball, Jennifer A. and Tuong, Tanduy D. and Arellano, Consuelo and Livingston, David P. and Milla-Lewis, Susana R.}, year={2018}, month={May}, pages={67} } @article{kimball_tuong_arellano_livingston_milla-lewis_2017, title={Assessing freeze tolerance in St. Augustinegrass: II. acclimation treatment effects}, volume={213}, ISSN={["1573-5060"]}, url={https://doi.org/10.1007/s10681-017-2074-2}, DOI={10.1007/s10681-017-2074-2}, number={12}, journal={EUPHYTICA}, publisher={Springer Science and Business Media LLC}, author={Kimball, Jennifer A. and Tuong, Tan D. and Arellano, Consuelo and Livingston, David P., III and Milla-Lewis, Susana R.}, year={2017}, month={Dec} } @article{kimball_tuong_arellano_livingston_milla-lewis_2017, title={Assessing freeze-tolerance in St. Augustinegrass: temperature response and evaluation methods}, volume={213}, DOI={10.1007/s10681-017-1899-z}, number={5}, journal={Euphytica}, author={Kimball, Jennifer A. and Tuong, Tan D. and Arellano, Consuelo and Livingston, David P., III and Milla-Lewis, Susana R.}, year={2017}, month={Apr} } @article{kim_jung_singh_greenberg_doyle_tyagi_chung_kimball_hamilton_mccouch_2017, title={Population dynamics among six major groups of the Oryza rufipogon species complex, wild relative of cultivated Asian rice (vol 9, 56, 2016)}, volume={10}, ISSN={["1939-8433"]}, DOI={10.1186/s12284-017-0156-3}, journal={RICE}, author={Kim, HyunJung and Jung, Janelle and Singh, Namrata and Greenberg, Anthony and Doyle, Jeff J. and Tyagi, Wricha and Chung, Jong-Wook and Kimball, Jennifer and Hamilton, Ruaraidh Sackville and McCouch, Susan R.}, year={2017}, month={Apr} } @article{kimball_isleib_reynolds_zuleta_milla-lewis_2016, title={Combining ability for winter survival and turf quality traits in st. augustinegrass}, volume={51}, number={7}, journal={HortScience}, author={Kimball, J.

A collection of 286 diverse ORSC accessions was evaluated for nuclear variation using genotyping-by-sequencing (113,739 SNPs) and for chloroplast variation using Sanger sequencing (25 polymorphic sites). Six wild subpopulations were identified, with 25 % of accessions classified as admixed. Three of the wild groups were genetically and geographically closely related to the O. sativa subpopulations, indica, aus and japonica, and carried O. sativa introgressions; the other three wild groups were genetically divergent, had unique chloroplast haplotypes, and were located at the geographical extremes of the species range. The genetic subpopulations were significantly correlated (r 2 = 0.562) with traditional species designations, O. rufipogon (perennial) and O. nivara (annual), differentiated based on morphology and life history. A wild diversity panel of 95 purified (inbred) accessions was developed for future genetic studies. Our results suggest that the cultivated aus subpopulation is most closely related to an annual wild relative, japonica to a perennial wild relative, and indica to an admixed population of diverse annual and perennial wild ancestors. Gene flow between ORSC and O. sativa is common in regions where rice is cultivated, threatening the identity and diversity of wild ORSC populations. The three geographically isolated ORSC populations harbor variation rarely seen in cultivated rice and provide a unique window into the genetic composition of ancient rice subpopulations.}, journal={RICE}, author={Kim, HyunJung and Jung, Janelle and Singh, Namrata and Greenberg, Anthony and Doyle, Jeff J. and Tyagi, Wricha and Chung, Jong-Wook and Kimball, Jennifer and Hamilton, Ruaraidh Sackville and McCouch, Susan R.}, year={2016}, month={Oct} } @article{imai_kimball_conway_yeater_mccouch_mcclung_2013, title={Validation of yield-enhancing quantitative trait loci from a low-yielding wild ancestor of rice}, volume={32}, ISSN={["1572-9788"]}, DOI={10.1007/s11032-013-9855-7}, number={1}, journal={MOLECULAR BREEDING}, author={Imai, Ize and Kimball, Jennifer A. and Conway, Benjamin and Yeater, Kathleen M. and McCouch, Susan R. and McClung, Anna}, year={2013}, month={Jun}, pages={101–120} } @article{kimball_zuleta_martin_kenworthy_chandra_milla-lewis_2012, title={Assessment of molecular variation within 'Raleigh' St. Augustinegrass using amplified fragment length polymorphism markers}, volume={47}, DOI={10.21273/hortsci.47.7.839}, abstractNote={St. augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] is a popular turfgrass in the southern United States as a result of its superior shade tolerance and relatively low input requirements. However, it is the least cold-tolerant of commonly used warm-season turfgrass species. ‘Raleigh’, released in 1980, has superior cold tolerance and is adapted and widely used in U.S. Department of Agriculture hardiness zones 8 to 9. More than 25 years after its release, ‘Raleigh’ is still the industry’s standard in terms of cold tolerance. However, the original foundation and breeder stock fields of the cultivar have been lost, placing the integrity of the cultivar at risk. The objectives of this study were to investigate whether current ‘Raleigh’ production fields across the southern United States are true to the original source. In this study, 15 amplified fragment length polymorphism (AFLP) primer combinations were used to assess levels of genetic variability among three original stocks of ‘Raleigh’ and 46 samples obtained from sod farms and universities in six states. Genetic similarities among the original stocks were Sij = 1, whereas similarities between this group and all other samples ranged from 0.24 to 1.0. Results based on cluster analysis, principal coordinate analysis, and analysis of molecular variance (AMOVA) revealed separation between original stocks of ‘Raleigh’ and some commercial samples. Results from this study offer further evidence that molecular markers provide a useful and powerful technique for identity preservation of clonally propagated cultivars and the detection of genetic variants in sod production fields and turfgrass breeding programs.}, number={7}, journal={HortScience}, publisher={American Society for Horticultural Science}, author={Kimball, J.
