Bacteria isolated from bengal cat (Felis catus × Prionailurus bengalensis) anal sac secretions produce volatile compounds associated with animal signaling

Mei Yamaguchi, Guillaume Jospin, Holly Ganz, David Coil, Jonathan Eisen, Adrienne Cho, Thant Zaw, Mitchell McCartney & Cristina Davis
Anal sacs are an important odor producing organ found across the mammalian Order Carnivora. Secretions from the anal sac may be used as chemical signals by animals for behaviors ranging from defense to species recognition to signaling reproductive status. In addition, a recent study suggests that domestic cats utilize short-chain free fatty acids in anal sac secretions for individual recognition. The fermentation hypothesis is the idea that symbiotic microorganisms living in association with animals contribute...

Signatures of Environmental Adaptation During Range Expansion of Wild Common Bean (Phaseolus vulgaris)

Paul Gepts
Landscape genomics integrates population genetics with landscape ecology, allowing the identification of putative molecular determinants involved in environmental adaptation across the natural geographic and ecological range of populations. Wild Phaseolus vulgaris, the progenitor of common bean (P. vulgaris), has a remarkably extended distribution over 10,000 km from northern Mexico to northwestern Argentina. Earlier research has shown that this distribution represents a range expansion from Mesoamerica to the southern Andes through several discrete migration events and...

Exploring the role of attitude in the acceptance of self-driving shuttles

YAN XING, Susan Handy, Giovanni Circella, Yunshi Wang & Farzad Alemi
Self-driving vehicles, as a revolution in mobility, are emerging and developing rapidly. However, public attitudes toward this new unproven technology are still uncertain. Given the significant influence of attitude toward a new technology on the intention to use it, the question arises as to why some people are in favor of this technology whereas others are not. Additionally, questions about the key attitudes influencing self-driving technology acceptance, where these attitudes come from, and how they...

Genome Synteny Has Been Conserved Among the Octoploid Progenitors of Cultivated Strawberry Over Millions of Years of Evolution

Michael Hardigan, Mitchell Feldmann, Anne Lorant, Kevin Bird, Steven Knapp, Patrick Edger, Glenn Cole, Charlotte Acharya & Randi Famula
Allo-octoploid cultivated strawberry (Fragaria × ananassa) originated through a combination of polyploid and homoploid hybridization, domestication of an interspecific hybrid lineage, and continued admixture of wild species over the last 300 years. While genes appear to flow freely between the octoploid progenitors, the genome structures and diversity of the octoploid species remain poorly understood. The complexity and absence of an octoploid genome frustrated early efforts to study chromosome evolution, resolve subgenomic structure, and develop a...

Data from: Evolution of sexually dimorphic pheromone profiles coincides with increased number of male-specific chemosensory organs in Drosophila prolongata

Yige Luo, Yuewei Zhang, Jean-Pierre Farine, Jean-François Ferveur, Santiago Ramírez & Artyom Kopp
Binary communication systems that involve sex-specific signaling and sex-specific signal perception play a key role in sexual selection and in the evolution of sexually dimorphic traits. The driving forces and genetic changes underlying such traits can be investigated in systems where sex-specific signaling and perception have emerged recently and show evidence of potential coevolution. A promising model is found in Drosophila prolongata, which exhibits a species-specific increase in the number of male chemosensory bristles. We...

Data from: Anthropogenic Basin Closure and Groundwater Salinization (ABCSAL)

Richard Pauloo
Global food systems rely on irrigated agriculture, and most of these systems in turn depend on fresh sources of groundwater. In this study, we demonstrate that groundwater development, even without overdraft, can transform a fresh, open basin into an evaporation dominated, closed-basin system, such that most of the groundwater, rather than exiting via stream baseflow and lateral subsurface flow, exits predominantly by evapotranspiration from irrigated lands. In these newly closed hydrologic basins, just as in...

Effect of Drought Stress on the Genetic Architecture of Photosynthate Allocation and Remobilization in Pods of Common Bean (Phaseolus vulgaris L.), a Key Species for Food Security

Paul Gepts, Jorge Carlos Berny Mier Y Teran, Enéas R. Konzen, Antonia Palkovic, Siu M. Tsai, Idupulapati M. Rao & Stephen Beebe
Background: Common bean is the most important staple grain legume for direct human consumption and nutrition. It complements major sources of carbohydrates, including cereals, root crop, or plantain, as a source of dietary proteins. It is also a significant source of vitamins and minerals like iron and zinc. To fully play its nutritional role, however, its robustness against stresses needs to be strengthened. Foremost among these is drought, which commonly affects its productivity and seed...

Is the USDA core collection of common bean representative of genetic diversity of the species, as assessed by SNP diversity?

Paul Gepts, Saarah Kuzay & Paige Hamilton
Core collections are envisioned to be a representative subset of larger germplasm collections. They were introduced to facilitate the characterization and use of these germplasm collections. The common bean (Phaseolus vulgaris) core collection of the USDA Western Regional Plant Introduction Station was one of the first ones to be established in the early 1990s. Here, we evaluate the representativity of this common bean collection in light of the availability of a SNP platform and new...

Genital morphology and the mechanics of copulation in the millipede genus Pseudopolydesmus (Diplopoda: Polydesmida: Polydesmidae)

Xavier Zahnle, Petra Sierwald, Stephanie Ware & Jason Bond
Mate choice, copulation, genital morphology, and sperm storage are not very well understood in millipedes. The use of three-dimensional x-ray computed tomography (µCT) provides new morphological data regarding millipede reproductive systems in both the female and male, including chitinous sclerites and membranes, muscles, glands, oviducts, and sperm conduits. Here we present a complete integrated account of the morphology and function of the female genital organs in the family Polydesmidae (Diplopoda: Polydesmida) using µCT, UV fluorescence...

Emissions estimates for different flight alternatives...

Low coverage whole genomes of Calypte anna across California, USA

Nicole Adams, Ruta Bandivadekar, Michael Clark, Lisa Tell & Rachael Bay
Recently, it was suggested that North America has lost nearly 30% of its avifauna since the 1970s. To mitigate such avian population declines, many birds in California are protected under the Migratory Bird Treaty Act and California Fish and Game Code. Avian presence, therefore, at Caltrans infrastructure projects, especially bridge construction, has caused costly delays. To avoid this conflict and understand population-specific migration and nesting patterns, we used Anna’s hummingbird, Calypte anna, (a species whose...

Dillon Fitch, Jane Carlen & Susan Handy
This tabular data can be used to evaluate perceived bicycling comfort on distinct state highways in California. The highway settings are primarily urban, but vary in traffic conditions, lane configurations, speeds, and bicycling infrastructure. The data include survey responses to video clips of these state highways along with a series of additional survey data that co-varies with the video survey responses.

Accuracy of genomic selection and long-term genetic gain for resistance to Verticillium wilt in a genetically diverse strawberry population

Steven Knapp, Dominique Pincot, Michael Hardigan, Glenn Cole, Peter Henry, Thomas Gordon & Randi Famula
Verticillium wilt, a soil-borne disease caused by the fungal pathogen Verticillium dahliae, threatens strawberry (Fragaria × ananassa) production worldwide. The development of resistant cultivars has been a challenge since the disease was first reported on strawberry in the early 1900s. The empirical evidence suggests that genetic gains have not been negligible and that the genetics of resistance to this pathogen is quantitative. While resistant cultivars have been developed, a comparatively small percentage are highly resistant,...

Domestic Well Vulnerability to Drought Duration and Unsustainable Groundwater Management in California's Central Valley

Richard Pauloo, Helen Dahlke, Graham Fogg, Herve Guillon, Amanda Fencl & Alvar Escriva-Bou
Millions of Californians access drinking water via domestic wells, which are vulnerable to drought and unsustainable groundwater management. Groundwater overdraft and the possibility of longer drought duration under climate change threatens domestic well reliability, yet we lack tools to assess the impact of such events. Here, we leverage 943,469 well completion reports and 20 years of groundwater elevation data to develop a spatially-explicit domestic well failure model covering California's Central Valley. Our model successfully reproduces...

Pod indehiscence is a domestication and aridity resilience trait in common bean

Travis Parker, Jorge Carlos Berny Mier Y Teran, Antonia Palkovic, Judy Jernstedt & Paul Gepts
Abstract Plant domestication has strongly modified crop morphology and development. Nevertheless, many crops continue to display some atavistic characteristics that were advantageous to their wild ancestors, such as pod dehiscence (PD). Here, we provide the first comprehensive assessment of the inheritance of PD in a domesticated grain legume, common bean (Phaseolus vulgaris). We compared three methods to evaluate the PD phenotype and identified multiple, unlinked genetic regions controlling PD using a biparental population and two...

Genomes From Bacteria Associated with the Canine Oral Cavity: a Test Case for Automated Genome-Based Taxonomic Assignment

David Coil, Guillaume Jospin, Jonathan Eisen, Aaron Darling, Collin Wallis, Ian Davis, Stephen Harris, Lucy Holcombe & Ciaran O'Flynn
Taxonomy for bacterial isolates is commonly assigned via sequence analysis. However, the most common sequence-based approaches (e.g. 16S rRNA gene-based phylogeny or whole genome comparisons) are still labor intensive and subjective to varying degrees. Here we present a set of 33 bacterial genomes, isolated from the canine oral cavity. Taxonomy of these isolates was first assigned by PCR amplification of the 16S rRNA gene, Sanger sequencing, and taxonomy assignment using BLAST. After genome sequencing, taxonomy...
