SNP analyses reveal a diverse pool of potential colonists to earthquake‐uplifted coastlines
<p>In species that form dense populations, major disturbance events are expected to increase the chance of establishment for immigrant lineages. Real-time tests of the impact of disturbance on patterns of genetic structure are, however, scarce. Central to testing these concepts is determining the pool of potential immigrants dispersing into a disturbed area. In 2016, a 7.8 magnitude earthquake occurred on the South Island of New Zealand. Affecting approximately 100 km of coastline, this quake caused extensive uplift (several metres high), extirpating many intertidal populations, including keystone intertidal kelp species. Following the uplift, we set out to determine the geographic origins of detached kelp specimens which rafted into the disturbed zone. Specifically, we used genotyping-by-sequencing (GBS) approaches to compare beach-cast southern bull-kelp (Durvillea antarctica and D. poha) samples to established populations throughout the species' ranges, and thus infer the geographic origins of potential colonists reaching the disturbed coast. Our findings reveal an ongoing supply of diverse lineages dispersing to the newly uplifted coastline, suggesting potential for establishment of 'exotic' lineages following disturbance. Furthermore, we found that some drifting individuals of each species came from far-distant regions, some >1200 km away. These results show that diverse lineages – in many cases from very distant sources – have potential to compete for new space in the wake of an exceptional disturbance event, illustrating the potential of long-distance dispersal as a key mechanism for re-assembly of coastal ecosystems. Furthermore, our findings demonstrate that high-resolution genomic baselines can be used to robustly assign the provenance of dispersing individuals.</p>
Data from: Resequencing of common bean identifies regions of inter-gene pool introgression and provides comprehensive resources for molecular breeding
Common bean is the most important grain legume for human consumption and a main nutrition source in the tropics. Because bean production is reduced by both abiotic and biotic constraints, current breeding efforts are focused on the development of improved varieties with tolerance to these stresses. We characterized materials from different breeding programs spanning three continents to understand their sequence diversity and advance the development of molecular breeding tools. For this, 37 varieties belonging to P. vulgaris, P. acutifolius, and P. coccineus were sequenced by whole-genome sequencing (WGS), identifying more than 40 million genomic variants. Evaluation of nuclear DNA content and analysis of copy number variation revealed important differences in genomic content not only between P. vulgaris and two other domesticated Phaseolus species, but also within P. vulgaris, affecting hundreds of protein-coding genomic regions. A large number of inter-gene-pool introgressions were identified. Furthermore, interspecific introgressions for disease resistance in breeding lines were mapped. Evaluation of newly developed SNP markers within previously discovered QTL for common bacterial blight and angular leaf spot provide improved specificity to tag sources of resistance to these diseases. We expect that this dataset will provide a deeper molecular understanding of breeding germplasm and deliver molecular tools for germplasm development, aiming to increase the efficiency of bean breeding programs.
Data from: Extraocular motoneuron pools develop along a dorsoventral axis in zebrafish, Danio rerio
Both spatial and temporal cues determine the fate of immature neurons. A major challenge at the interface of developmental and systems neuroscience is to relate this spatiotemporal trajectory of maturation to circuit‐level functional organization. This study examined the development of two extraocular motor nuclei (nIII and nIV), structures in which a motoneuron's identity, or choice of muscle partner, defines its behavioral role. We used retro‐orbital dye fills, in combination with fluorescent markers for motoneuron location and birthdate, to probe spatial and temporal organization of the oculomotor (nIII) and trochlear (nIV) nuclei in the larval zebrafish. We describe a dorsoventral organization of the four nIII motoneuron pools, in which inferior and medial rectus motoneurons occupy dorsal nIII, while inferior oblique and superior rectus motoneurons occupy distinct divisions of ventral nIII. Dorsal nIII motoneurons are, moreover, born before motoneurons of ventral nIII and nIV. The order of neurogenesis can therefore account for the dorsoventral organization of nIII and may play a primary role in determining motoneuron identity. We propose that the temporal development of extraocular motoneurons plays a key role in assembling a functional oculomotor circuit.

Divergent contributions of living roots to turnover of different soil organic carbon pools and their links to plant traits
<p>1. Rhizodeposits and root litter contribute critically to soil organic carbon (SOC) formation and decomposition. This root-induced SOC turnover shows great interspecific variations. Bulk SOC consists of diverse functional pools differing in formation and stabilization. Yet, it remains unclear which plant traits regulate the effects of living roots on the turnover of different SOC pools across species.</p> <p>2. By performing <sup>13</sup>CO<sub>2 </sub>continuous<sub> </sub>labelling of six grassland species for a growing season in a climate-controlled chamber, we quantified the contributions of living roots to the dynamics of the fast-cycling particulate organic C and the slow-cycling mineral-associated organic C, and explored their relations to plant traits.</p> <p>3. The results showed that new root-derived SOC varied more than threefold among the six species. The variation in new root-derived SOC was best explained by the ratio of shoot to root biomass. Plant species with higher shoot:root ratio formed more new root-derived SOC. Most of the root-derived C (72%) was incorporated into the particulate organic C pool. All species caused positive rhizosphere priming effects (RPE), which varied sevenfold across species. Among plant traits, specific root length was the best predictor of interspecific variations in the RPE, with greater RPE associated with higher specific root length. Most of the RPE (70%) occurred in the mineral-associated organic C pool. Our results also showed that most plant species caused more old SOC decomposition via the RPE than new SOC formation, leading to net SOC losses, especially for the mineral-associated organic C pool.</p> <p>4. Overall, we provide novel insights into the effects of plant traits on root-induced turnover of particulate and mineral-associated organic C. Our findings should be valuable for understanding how specific plant traits regulate SOC accumulation and stabilization.</p>
