- Symbiosis in the microbial world: from ecology to genome evolution
Summary: At a recent Company of Biologists workshop, evolutionary biologists discussed the major outstanding questions in symbiosis research.
RESEARCH ARTICLES
- Site-1 protease regulates skeletal stem cell population and osteogenic differentiation in mice
Summary: S1P governs a fundamental aspect of skeletal development and homeostasis, mainly the maintenance and osteogenic differentiation of skeletogenic stem cells that are a source of osteoblast and chondrocyte lineages.
- Mechanical properties of silk of the Australian golden orb weavers Nephila pilipes and Nephila plumipes
Summary: Spider silk is a remarkably tough and extensible biomaterial. We identified macrostuctural and mechanical differences in outer web frame silk of two Australian orb-weaving spiders.
- Ecdysone signaling regulates specification of neurons with a male-specific neurite in Drosophila
Summary: The insect molting hormone ecdysone determines whether a single neuron develops a sex-specific structure, through crosstalk with signaling elements in a pathway dedicated to the sex-fate determination.
- Timing and context of dolphin clicks during and after mine simulator detection and marking in the open ocean
Summary: Dolphins wore cameras so we could hear them and watch them mark mine simulators. We observed rhythmic click trains, victory squeals, and click packets with their behavioral context.
- The histone deacetylase HDAC1 positively regulates Notch signaling during Drosophila wing development
Summary: The histone deacetylase HDAC1 acts as a positive regulator of Notch signaling during Drosophila wing development, and its depletion causes wing notches on the margin of adult wing.
- Spermine modulates fungal morphogenesis and activates plasma membrane H+-ATPase during yeast to hyphae transition
Summary: This study presents a new mechanistic model for the integrative role of the polyamine spermine and hormone auxin in the signaling of yeast-to-hypha transition, filling an important gap in fungal morphogenesis.
- Metabolism of the Pacific oyster, Crassostrea gigas, is influenced by salinity and modulates survival to the Ostreid herpesvirus OsHV-1
Summary: Environmental salinity influences energetic reserves, enzyme activity, membrane fatty acids of the Pacific oyster and modulates survival to viral infection.
- Sustained exercise-trained juvenile black carp (Mylopharyngodon piceus) at a moderate water velocity exhibit improved aerobic swimming performance and increased postprandial metabolic responses
Summary: Sustained exercise training at a moderate water velocity had positive effects on aerobic swimming performance and postprandial metabolic responses in juvenile black carp (Mylopharyngodon piceus).
- Human hepatocyte depletion in the presence of HIV-1 infection in dual reconstituted humanized mice
Summary: We describe a model that recapitulates multiple components of liver damage by HIV-1 infection as in humans, including reduced liver CD4+ cells, albumin levels, liver immune activation and human hepatocyte survival.
- How does the snakehead Channa argus survive in air? The combined roles of the suprabranchial chamber and physiological regulations during aerial respiration
Summary: The aerial survival of the northern snakehead could be involved with suprabranchial chamber respiration, and also with physiological regulations.
- Plastid translation is essential for lateral root stem cell patterning in Arabidopsis thaliana
Summary: Successful plastid gene expression is required for stem cell patterning in lateral root primordia as revealed by genetic and pharmacological impairment of plastid translation.
- A transgenic zebrafish model for the in vivo study of the blood and choroid plexus brain barriers using claudin 5
Summary: A novel transgenic zebrafish, using claudin 5a, represents an ideal model to study blood brain barrier and choroid plexus barrier development and function in vivo.
- Gemin4 is an essential gene in mice, and its overexpression in human cells causes relocalization of the SMN complex to the nucleoplasm
Summary: Gemin4 loss-of-function is recessive lethal in mice, whereas in cell culture its overexpression results in a dominant, gain-of-function relocalization of SMN and other Gemin proteins to the nucleus.

Cover article - Apolipoprotein L9 interacts with LC3/GABARAP and is a microtubule-associated protein with a widespread subcellular distribution
Arvind A. Thekkinghat, Kamlesh K. Yadav and Pundi N. Rangarajan demonstrate the versatile properties of apolipoprotein L9, a lipid-binding protein, and its influence on a variety of activities taking place inside an animal cell.
James J. Dowling and his colleagues conducted the first large-scale screening efforts for NEBLUN-related nemaline myopathy to address the urgent need for effective treatment for patients affected by the disease.
Have you seen our interviews with the early-career first authors of our papers? Recently, we caught up with first authors Arvind Thekkinghat, Shannon Taylor and Daisuke Takao.
Biology Open has strong credentials and publishing with us is easy and fast. BiO aims to provide rapid publication for scientifically sound observations and valid conclusions in developmental, cell, experimental and translational biology. Submit your paper here – you’ll be in good company!
Recent developmental biology highlights in BiO – Anna Nele Herdina and her colleagues define the spectrum of phenotypic abnormalities linked with Col4a2 disruption, and demonstrate the opportunities the Deciphering the Mechanisms of Developmental Disorders (DMDD) program offers for exploring rare human diseases.
Transfer to Biology Open
Did you know: if your submission to one of our sister journals, Development, Journal of Cell Science, Journal of Experimental Biology or Disease Models & Mechanisms, is unsuccessful, you can transfer your paper and any reviews directly to Biology Open. The majority of papers transferred with reviews are accepted for publication. Read here to find out more.
BiO partners with Publons.
Biology Open is pleased to announce a new partnership with Publons. This allows reviewers to easily track and verify every review by choosing to add the review to their Publons profile when completing the review submission form. Publons makes it simple for reviewers to showcase their peer review contributions in a format that can be included in job and funding applications (without breaking reviewer anonymity).
