RESEARCH ARTICLES
Root system architecture analysis in Mesembryanthemum crystallinum (ice plant) seedlings reveals characteristic root halotropic response
Summary: Halotropism is one of the key root growth traits that facilitates adaptation to saline soil conditions. The halophyte Mesembryanthemum crystallinum (ice plant), exhibited halotropic root growth under high salinity conditions.
Avoiding being stung or bitten – prey capture behaviors of the ant-eating Texas horned lizard (Phrynosoma cornutum)
Summary: Horned lizards, primarily feeding on dangerous and venomous harvester ants, avoid being bitten or stung by striking ants mainly on the thorax, avoiding head and gaster.
The physiological reaction of Siberian hamsters (Phodopus sungorus, Cricetidae) to chemical signals of perspective mating partners before and during courtship
Summary: Perception of olfactory signals before and during courtship lead to an increase of non-specific immune activity. For pairs formed by mutual preference there was a noted decrease of stress-hormone only in females.
A Caenorhabditis elegans behavioral assay distinguishes early stage prostate cancer patient urine from controls
Summary: The nematode Caenorhabditis elegans shows behavioral attraction to urine from prostate cancer patients, but not to controls, and this phenomenon may be a useful tool for designing diagnostic assays or biomarker discovery.
Spatial odor discrimination in the hawkmoth, Manduca sexta (L.)
Summary: The proboscis extension reflex (PER) associative learning protocol was used as a tool to ask if hawkmoths, Manduca sexta, can discriminate between odor stimuli arriving on either antenna.
The thermal dependence and molecular basis of physiological color change in Takydromus septentrionalis (Lacertidae)
Summary: G protein-coupling system inhibits adenylate cyclase activity to transform ATP into cAMP and thereby causes rapid pigment aggregation. MCH deactivates the G proteins and thereby initiates pigment dispersion.
Cex1 is a component of the COPI intracellular trafficking machinery
Summary: Cex1, the yeast homologue of mammalian SCYL1, interacts with COPI coat components and is recruited to the Golgi to regulate retrograde vesicular trafficking and sorting
Interdomain interactions regulate the localization of a lipid transfer protein at ER-PM contact sites
Summary: This study demonstrates interdomain interactions within a phosphatidylinositol transfer protein that regulate its localization and function at an ER-PM membrane contact site.
A zebrafish forward genetic screen identifies an indispensable threonine residue in the kinase domain of PRKD2
Summary: We identified, through a zebrafish forward screen, an evolutionarily conserved residue in the catalytic domain of protein kinase D2 and its homologues.
A glucose-supplemented diet enhances gut barrier integrity in Drosophila
Summary: How diet affects lifespan has received much attention. We found that maintenance of intestinal barrier integrity is likely an important factor in glucose-dependent lifespan extension in flies.
LIM Homeobox 9 knockdown by morpholino does not affect zebrafish retinal development
Summary:lhx9 is expressed in the development of the zebrafish heart, pectoral fin, and retina, but lhx9 knockdown by morpholino does not affect zebrafish retinal development.
Conditional targeting of phosphatidylserine decarboxylase to lipid droplets
Summary: A form of mitochondrial phosphatidylserine decarboxylase that is generated by alternative pre-mRNA splicing is shown to localize to the surface of lipid droplets.
Biophysical and biochemical properties of Deup1 self-assemblies: a potential driver for deuterosome formation during multiciliogenesis
Summary: Deuterosome protein 1 (Deup1) self-assembles into stable condensates that can be the structural core of the deuterosome during multiciliogenesis.
METHODS & TECHNIQUES
The SARS-CoV-2 receptor and other key components of the Renin-Angiotensin-Aldosterone System related to COVID-19 are expressed in enterocytes in larval zebrafish
Summary: Genomic analyses identify zebrafish orthologs of the Renin-Angiotensin-Aldosterone System that contribute to COVID-19 comorbidities and single-cell transcriptomics shows that they act in a specialized intestinal cell type.
Integrated analysis of cell shape and movement in moving frame
Summary: We developed a novel approach to integrate the analysis of cell shape and movement using moving frame.

Read & Publish Open Access publishing: what authors say
We have had great feedback from authors who have benefitted from our Read & Publish agreement with their institution and have been able to publish Open Access with us without paying an APC. Read what they had to say.
Gatekeeping at BiO
In his Editorial, BiO Editor-in-Chief Dan Gorelick outlines the criteria by which articles submitted to BiO are assessed, as part of initiatives to increase transparency of journal 'gatekeeping'.
The Forest of Biologists
Our Publisher Claire Moulton recently visited the two Woodland Trust UK sites where we are planting new native trees for published Research and Review papers and protecting ancient woodland on behalf of our peer reviewers.
A Year at the Forefront
This series of Review articles aims to highlight the key discoveries, technological innovations, new resources and new hypotheses that have made an impact in a specific biological field during the past year. This publishing opportunity is available to early-career researchers, without a publication charge. Find out about eligibility and how to submit a proposal.
How we support early-career researchers
Biology Open, its sister journals and its not-for-profit publisher, The Company of Biologists, support early-career researchers in numerous ways, helping them grow their network and raise their profile. Find out what we can do to support you.
