Data from: Imputation of canine genotype array data using 365 whole-genome sequences improves power of genome-wide association studies

Genomic resources for the domestic dog have improved with the widespread adoption of a 173k SNP array platform and updated reference genome. SNP arrays of this density are sufficient for detecting genetic associations within breeds but are underpowered for finding associations across multiple breeds or in mixed-breed dogs, where linkage disequilibrium rapidly decays between markers, even though such studies would hold particular promise for mapping complex diseases and traits. Here we introduce an imputation reference panel, consisting of 365 diverse, whole-genome sequenced dogs and wolves, which increases the number of markers that can be queried in genome-wide association studies approximately 130-fold. Using previously genotyped dogs, we show the utility of this reference panel in identifying potentially novel associations, including a locus on CFA20 significantly associated with cranial cruciate ligament disease, and fine-mapping for canine body size and blood phenotypes, even when causal loci are not in strong linkage disequilibrium with any single array marker. This reference panel resource will improve future genome-wide association studies for canine complex diseases and other phenotypes.

Integron array MICs and cassettes transcription data

Mobile integrons are widespread genetic platforms that allow bacteria to modulate the expression of antibiotic resistance cassettes by shuffling their position from a common promoter. Antibiotic stress induces the expression of an integrase that excises and integrates cassettes, and this unique recombination and expression system is thought to allow bacteria to 'evolve on demand' in response to antibiotic pressure. To test this hypothesis, we inserted a custom three cassette integron into P. aeruginosa, and used experimental evolution to measure the impact of integrase activity on adaptation to gentamicin. Crucially, integrase activity accelerated evolution by increasing the expression of a gentamicin resistance cassette through duplications and by eliminating redundant cassettes. Importantly, we found no evidence of deleterious off-target effects of integrase activity. Our results show that integrons accelerate resistance evolution by rapidly generating combinatorial variation in cassette composition while maintaining genomic integrity, and they highlight the importance of semi-conservative cassette excision for integron dynamics.

Tool for genomic selection and breeding to evolutionary adaptation: Development of a 100K single nucleotide polymorphism array for the honey bee

High-throughput high density genotyping arrays continue to be a fast, accurate, and cost-effective method for genotyping thousands of polymorphisms in high numbers of individuals. Here we have developed a new high-density SNP genotyping array (103 270 SNPs) for honey bees, one of the most ecologically and economically important pollinators worldwide. SNPs were detected by conducting whole genome resequencing of 61 honey bee drones (haploid males) from throughout Europe. Selection of SNPs for the chip was done in multiple steps using several criteria. The majority of SNPs were selected based on their location within known candidate regions or genes underlying a range of honey bee traits, including hygienic behaviour against pathogens, foraging and subspecies. Additionally, markers from a GWAS of hygienic behaviour against the major honey bee parasite Varroa destructor, were brought over. The chip also includes SNPs associated with each of three major breeding objectives - honey yield, gentleness and Varroa resistance. We validated the chip and make recommendations for its use by determining error rates in repeat genotypings, examining the genotyping performance of different tissues, and by testing how well different sample types represent the queen's genotype. The latter is a key test because it is highly beneficial to be able to determine the queen's genotype by non-lethal means. The array is now publicly available and we suggest it will be a useful tool in genomic selection and honey bee breeding, as well as for GWAS of different traits, and for population genomic, adaptation and conservation questions.

SNP array for parentage assignment of the Manila clam, Ruditapes philippinarum

The Manila clam Ruditapes philippinarum, a major cultured shellfish species, is threatened by infection with the microparasite Perkinsus olseni, whose prevalence increases with high water temperatures. Under the current trend of climate change, the already severe effects of this parasitic infection might rapidly increase the frequency of mass mortality events. Treating infectious diseases in bivalves is notoriously problematic, therefore selective breeding for resistance represents a key strategy for mitigating the negative impact of pathogens. A crucial step in initiating selective breeding is the estimation of genetic parameters for traits of interest, which relies on the ability to record parentage and accurate phenotypes in a large number of individuals. Here, to estimate the heritability of resistance against P. olseni, a field experiment mirroring conditions in industrial clam production was set up, a genomic tool was developed for parentage assignment, and parasite load was determined through quantitative PCR. A mixed-family cohort of potentially 1479 clam families was produced in a hatchery by mass spawning of 53 dams and 57 sires. The progenies were seeded in a commercial clam production area in the Venice lagoon, Italy, where high prevalence of P. olseni had previously been reported. Growth and parasite load were monitored every month and, after one year, more than 1000 individuals were collected and DNA and phenotype records. A 245-SNP panel was developed using candidate markers obtained from a pooled sequencing approach on two DNA samples from all the potential parents and from a Venice lagoon clam population. For 246 individuals of the mixed-family F1, sire and dam representation were high (75 and 85%, respectively), indicating a very limited risk of inbreeding. Moderate heritability (0.20 – 0.30) was estimated for growth traits, while parasite load showed high heritability, estimated at 0.52. No significant genetic correlations were found between growth-associated traits and parasite load. Overall, the study shows high potential for selecting clams resistant to parasite load. Breeding for resistance may help limit the negative effects of climate change on clam production, as the prevalence of the parasite is predicted to increase under a future scenario of higher temperatures. Finally, the limited genetic correlation between resistance and growth suggests that breeding programs could incorporate dual selection without negative interactions.

Locating large insects using automated VHF radio telemetry with a multi-antennae array

1. We describe an automated radio telemetry system (ARTS) designed for estimating the location of 0.50g butterflies that was constructed with commercially available materials. Previously described systems were not designed to estimate fine-scale locations of large insects within approximately 200m$^2$ study areas. 2. The ARTS consists of four receiving stations. Each receiving station has four 3-element, directional Yagi antennae (separated by 60\si{\degree}) connected to an automated receiver that records detected power sequentially from each antenna. To develop and evaluate the ARTS performance, four receiving stations were installed in the corners of 4-ha and 6.25-ha square fields with varying heights of vegetative cover. The location of a 0.22g transmitter was estimated with a statistical method implementing both distance- and angle-power relationships. Calibrated model parameters were based on power detected from transmitters at known locations. Using independently collected data, model performance was evaluated based on estimated locations of a georeferenced stationary transmitter, a moving transmitter with a known georeferenced path, and a transmitter attached to a monarch butterfly (\textit{Danaus plexippus}). Estimated locations were calculated as frequently as every 5 seconds, which is at least 12 times greater than the sampling frequency previously reported for tracking insects. 3. When sufficient power data was received, the median estimated locations of a transmitter attached to an investigator's hat were $<$16m from the true location. The median effective radius of the 95\% confidence ellipse was 18.3m for stationary targets and 15.9m for a moving transmitter. Greater error in location estimation was expected when the transmitter was attached to a monarch butterfly due to interference from vegetation and variability in antenna orientation and transmitter height. As such, the median distance between the estimated and true locations was 72m. After applying a correction for the effect of vegetation, median location error was reduced by 12m. 4. While our ARTS has likely reached the limit of current technology, the system is still a substantial methodological advancement for locating butterflies. Our efforts should provide a benchmark as technology improves.

This dataset contains a recording of X-band telemetry signals from the Chinese lunar sample retrieve mission Chang'e 5 done on 2020-11-29 before and during the LOI-2 (lunar orbit injection 2) manoeuvre that circularized the spacecraft's elliptical lunar orbit. The recording was done at Allen Telescope Array using antenna 1h in dual XY (linear) polarization. The hardware configuration was as follows: antenna 1h was connected to RFCB LO d, which was tuned to a frequency of 8475 MHz and used an output IF of 512 MHz. A USRP N321 was connected to the IF output of the RFCB and digitized both polarizations. The USRP used external 10 MHz reference and PPS coming from the observatory distribution system. The IQ  sample rate of the USRP was 30.72 Msps and a GNU Radio flowgraph was used to channelize four frequencies from the spacecraft (8463.7, 8471.2, 8478.6 and 8486.2 MHz), using an IQ sample rate of 240 ksps for each channel.

Data from: Experimental evaluation of spectral efficiency from a circular array antenna producing a Laguerre-Gauss mode

We present the 4D volumetric electromagnetic field measurements (x, y, z and frequency) of the complex radiated field produced by an 8-element circular antenna array. The array is designed to produce a Laguerre-Gauss (LG) mode l = -1 over the frequency range of 9 - 10 GHz. We evaluate our findings in terms of far-field LG mode purity and spectral efficiency in terms of the QAM modulation scheme that can be supported. The application of LG modes in radio systems is as a means of multiplexing several data streams onto the same frequency, polarisation and time slot, thus making highly spectrally efficient transmission system or enhancing radar systems by means of exploiting mode behaviour as an additional degree of freedom. Our results show that for the circular antenna array, we find that mode purity allows BPSK or QPSK modulation over a 0.3GHz bandwidth. Closer to the antennas' design frequency, 256QAM modulation may be used over a 0.05 GHz band. We anticipate the practical insights provided in this paper to contribute to the successful design of such systems.
