    Practical evaluation of SEEK and OpenBIS for biological data management in SynthSys; first report

    Author contributions: ET and TZ evaluated systems and developed software; IC, PS and AJM provided use cases; AJM and TZ designed the evaluation; ET, TZ and AJM wrote the report with input from all authors. Acknowledgements: We gratefully acknowledge training and support from the SEEK and OpenBIS project teams, who also checked this document.The project evaluated two existing data management systems for a small set of users, who represent diverse needs within the SynthSys Centre, in order to inform wider adoption for biological research. SEEK’s strengths are support for the Investigation, Study, Assay (ISA) standard and a fine grained access control. This makes SEEK an excellent tool for collaborative work and publishing results. OpenBIS is well suited for automatic metadata processing and incorporation into analysis workflows. Both data management systems provided useful and complementary functionality, so our recommendation is that both are hosted for use in SynthSys. This also aligns well with the EU FAIRDOM project which is currently integrating SEEK and OpenBIS into one platform

    Changing planetary rotation rescues the biological clock mutant lhy cca1 of Arabidopsis thaliana

    Author contributions. AJM and SKH designed the study. JC and WVT performed experiments and analysed data under supervision of SKH. AJM performed additional analysis and wrote the paper. Acknowledgements. We are grateful to Kieron Edwards and Adrian Thomson for performing the experiments shown in Figure 3, to Tomasz Zielinski for the online BioDare resource and to members of the Millar laboratory for data curation in BioDare.Background: Pervasive, 24-hour rhythms from the biological clock affect diverse biological processes in metabolism and behaviour, including the human cell division cycle and sleep-wake cycle, nightly transpiration and energy balance in plants, and seasonal breeding in both plants and animals. The clock mechanism in the laboratory model plant species Arabidopsis thaliana is complex, in part due to the multiple interlocking, negative feedback loops that link the clock genes. Clock gene mutants are powerful tools to manipulate and understand the clock mechanism and its effects on physiology. The LATE ELONGATED HYPOCOTYL and CIRCADIAN CLOCK ASSOCIATED 1 genes encode dawn-expressed, Myb-related repressor proteins that delay the expression of other clock genes until late in the day. Double mutant plants (lhy cca1) have low-amplitude, short-period rhythms that have been used in multiple studies of the plant circadian clock. Results: We used in vivo imaging of several luciferase (LUC) reporter genes to test how the rhythmic gene expression of wild-type and lhy cca1 mutant plants responded to light:dark cycles. Red, blue and red+blue light were similarly able to entrain these gene expression rhythms. The timing of expression rhythms in double mutant plants showed little or no response to the duration of light under 24h light:dark cycles (dusk sensitivity), in contrast to the wild type. As the period of the mutant clock is about 18h, we tested light:dark cycles of different duration (T cycles), simulating altered rotation of planet Earth. lhy cca1 double mutants regained as much dusk sensitivity in 20h T cycles as the wild type in 24h cycles, though the phase of the rhythm in the mutants was much earlier than wild type. The severe, triple lhy cca1 gi mutants also regained dusk sensitivity in 20h cycles. The double mutant showed some dusk sensitivity under 28h cycles. lhy cca1 double mutants under 28h cycles with short photoperiods, however, had the same apparent phase as wild-type plants. Conclusion: Simulating altered planetary rotation with light:dark cycles can reveal normal circadian performance in clock mutants that have been described as arrhythmic under standard conditions. The features rescued here comprise a dynamic behaviour (apparent phase under 28h cycles) and a dynamic property (dusk sensitivity under 20h cycles). These conditional clock phenotypes indicate that parts of the clock mechanism continue to function independently of LHY and CCA1, despite the major role of these genes in wild-type plants under standard conditions.

    The weed community affects yield and quality of soybean (Glycine max (L.) Merr.)

    The relationship between the weed community and soybean (Glycine max (L.) Merr.) seed yield and quality was assessed in two soybean experiments in Illinois, USA. One field was sown with different proportions of target weeds (Ambrosia trifida L., Amaranthus rudis J. Sauer, Setaria faberi F. Herrm), and the other was naturally infested with these and other weeds. The composition of the weed communities in both fields were compared to final yield and quality (% protein, oil, and water) of the crop using NMDS ordination. Biomass and canopy cover, and seed quality (% protein, relative water content, seed weight) of the crop, were related to the multivariate structure of the weed community in both experiments. Lower quality soybeans were harvested from plots dominated by the target weeds and a suite of subordinate volunteers. Analysis restricted to the volunteer weed community was also significantly related to seed protein and seed weight. Similar results from the two experiments lend generality to the findings and indicate that soybean producers need to manage the composition of the weed community
