Maternal and Embryonic Stress Influence Offspring Behavior in the Cuttlefish Sepia officinalis
Frontiers in Physiology, 2017 Stress experienced during prenatal development—either applied to reproducing females (maternal stress), directly to developing offspring (embryonic stress) or in combination—is associated with a range of post-natal behavioral effects in numerous ...

Short and random: Modelling the effects of (proto-)neural elongations [PDF]
, 2017 To understand how neurons and nervous systems first evolved, we need an account of the origins of neural elongations: Why did neural elongations (axons and dendrites) first originate, such that they could become the central component of both neurons and ...

ERK1/2 is an ancestral organising signal in spiral cleavage
Nature Communications, 2022 How invertebrates with spiral cleavage establish their body plans is unclear. Here the authors show that, like molluscs, a basal annelid uses ERK1/2 to instruct body patterning, suggesting that this is a deep ancestral trait in animal embryogenesis.

Frontiers in Cell and Developmental Biology, 2022 Specification and elaboration of proximo-distal (P-D) axes for structures or tissues within a body occurs secondarily from that of the main axes of the body. Our understanding of the mechanism(s) that pattern P-D axes is limited to a few examples such as

Frontiers in Physiology, 2021 The speed of adaptive body patterning in coleoid cephalopods is unmatched in the natural world. While the literature frequently reports their remarkable ability to change coloration significantly faster than other species, there is limited research on ...

Role of the hindbrain in dorsoventral but not anteroposterior axial specification of the inner ear [PDF]
, 2005 An early and crucial event in vertebrate inner ear development is the acquisition of axial identities that in turn dictate the positions of all subsequent inner ear components.

Pattern formation during de novo assembly of the Arabidopsis shoot meristem [PDF]
, 2007 Most multicellular organisms have a capacity to regenerate tissue after wounding. Few, however, have the ability to regenerate an entire new body from adult tissue. Induction of new shoot meristems from cultured root explants is a widely used, but poorly

Anterior-posterior gene expression differences in three Lake Malawi cichlid fishes with variation in body stripe orientation [PDF]
PeerJ, 2017 Morphological differentiation among closely related species provides opportunities to study mechanisms shaping natural phenotypic variation. Here, we address variation in the orientation of melanin-colored body stripes in three cichlid species of the ...

A multi-protein receptor-ligand complex underlies combinatorial dendrite guidance choices in C. elegans. [PDF]
, 2016 Ligand receptor interactions instruct axon guidance during development. How dendrites are guided to specific targets is less understood. The C. elegans PVD sensory neuron innervates muscle-skin interface with its elaborate dendritic branches.
