The Hordeum Toolbox: The Barley Coordinated Agricultural Project Genotype and Phenotype Resource

The use of DNA markers in public sector plant breeding is now the norm. Such markers are common across breeding programs and this commonality enables and enhances collaboration. Therefore, large collaborative research projects that measure several phenotypes across multiple environments coupled with the expanding amount of genotype data attainable with current marker technologies are on the rise and these projects demand efficient data delivery. However, development of computational tools for advanced data integration, visualization, and analysis is still a bottleneck, even though these resources have the greatest potential impact for users who are extracting and developing hypothesis-based solutions. The Hordeum Toolbox (THT) was developed as a data resource for the Barley Coordinated Agricultural Project (CAP) with the novel capability of constructing user-defined downloadable sets of phenotype and/or genotype data for downstream analysis. Internal tools in THT enable users to create clusters of a selected group of lines based on genotype data, parse pedigrees, and select germplasm based on haplotype, phenotype, and agronomic properties. The Hordeum Toolbox can be adapted to breeding programs or collaborations to assist researchers in germplasm selection, genotype data visualization, and the integration of complex data sets for statistical analysisThis is the publisher’s final pdf.

A communal catalogue reveals Earth's multiscale microbial diversity

Our growing awareness of the microbial world's importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth's microbial diversity.Peer reviewe

Neighborhoods and health

Features of neighborhoods or residential environments may affect health and contribute to social and race/ethnic inequalities in health. The study of neighborhood health effects has grown exponentially over the past 15 years. This chapter summarizes key work in this area with a particular focus on chronic disease outcomes (specifically obesity and related risk factors) and mental health (specifically depression and depressive symptoms). Empirical work is classified into two main eras: studies that use census proxies and studies that directly measure neighborhood attributes using a variety of approaches. Key conceptual and methodological challenges in studying neighborhood health effects are reviewed. Existing gaps in knowledge and promising new directions in the field are highlighted.http://deepblue.lib.umich.edu/bitstream/2027.42/78378/1/DiezRouxMair2010_AnnNYAcadSci.pd

Policies and Practices for Hiring Effective Teachers: A Qualitative Study of Louisiana Public Schools

The purpose of this research was to explore individual district hiring policies within Louisiana. The primary question guiding this research was: Is there a particular process currently used by districts in the state of Louisiana that leads to hiring a greater number of effective teachers? Qualitative methodological procedures used in this research explored current policies throughout Louisiana in relation to teacher hiring. Using a case study, data was collected in two phases: (1) an extensive review of the policies in 17 districts; and (2) interviews of five district personnel. The document review uncovered 7 themes and 25 codes essential in the process of hiring teachers. Those themes were: (1) documentation; (2) positions; (3) contracts and compensation; (4) qualifications and duties; (5) recruitment; (6) employment; and (7) assignment. Interviews were used to determine how individual districts were implementing state and federal policy. Finally, three major findings were discovered as a result of the research: (1) Louisiana suffers from pockets of insufficient teacher supply; (2) technology, including social media, can serve as a valuable tool in recruiting and hiring of effective teachers; and (3) no major distinction in hiring practices across districts. An implication for educational leaders include reviewing current policy to eliminate barriers which may prevent the use of technology as a recruiting tool for K-12 educators

A Physiological Investigation of Adventitious Root Initiation in the Genus Acer

215 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1981.Differences in adventitious root initiation among species in the genus Acer were investigated. Acer ginnala, A. rubrum and A. saccharinum were easily rooted from softwood stem cuttings. Acer saccharum was moderately difficult to root from cuttings. Acer griseum was the most difficult-to-root species in this study. Optimum IBA treatments for root initiation were determined for these five species.The total free phenolic content of these five Acer species varied among species, plant parts and dates sampled. Leaves accounted for the largest share of the total phenolic content followed by young stems and old stems. Easy-to-root species, Acer ginnala, A. rubrum and A. saccharinum, had a higher content of total phenols than difficult-to-root species, A. griseum and A. saccharum. These experiments suggest that differences and changes in total phenolic content may help to explain some of the differences in ease of propagation of plants from cuttings.The role of phenolic compounds in root initiation and their relationship to extracted rooting promoters and inhibitors was studied. Combinations of catechol and IAA stimulated root initiation in cuttings of Acer griseum and A. saccharinum. Treatment of Acer griseum cuttings with a combination of IAA and catechol for 24 hours resulted in 100% rooting and increased numbers of roots per cutting.Crude methanolic extracts from leaves, young stems and old stems of Acer ginnala, A. rubrum and A. saccharinum contain substances that stimulate root initiation. Crude extracts from leaves, young stems and old stems of Acer griseum and A. saccharum appeared to contain the same substances at lower concentrations. The higher concentrations of these stimulatory substances in tissues of Acer ginnala, A. rubrum and A. saccharinum may account for the relative ease of propagating these species from cuttings compared to cuttings of A. griseum and A. saccharum.Fractionation of crude extracts from leaves of Acer ginnala in 80% isopropanol with descending paper chromatography revealed the presence of stimulatory compounds with R(,f) values of 0.7 (compound 0.7) and 0.9 (compound 0.9). Compound 0.7 occurred in the highest concentration in leaves of easy-to-root species, but may occur at lower concentrations in all plant parts of the five species tested. Compound 0.7, extracted from leaves of Acer ginnala, was first observed as an inhibitor of root initiation in the mung bean bioassay. However, this compound was strongly stimulatory to root initiation when tested at lower concentrations. Therefore, a single concentration of an extract cannot be used to assess the presence of inhibitors of root initiation.Compound 0.7 applied in combination with IAA stimulated root initiation in softwood tip cuttings of Acer saccharinum and A. griseum. The results obtained with Acer griseum indicate that compound 0.7 may hold promise in rooting other difficult-to-root species. Several experiments indicated that the compounds at R(,f) 0.7 were phenols.Stimulatory compounds with an R(,f) of 0.9 occurred in all plant parts of all species studied. These compounds stimulated adventitious root initiation in the mung bean bioassay, but did not stimulate root initiation in softwood stem cuttings of Acer saccharinum or A. griseum.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
