A diploblastic radiate animal at the dawn of cambrian diversification with a simple body plan: distinct from Cnidaria? [PDF]
PLoS ONE, 2013 Microfossils of the genus Punctatus include developmental stages such as blastula, gastrula, and hatchlings, and represent the most complete developmental sequence of animals available from the earliest Cambrian.

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 ...

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 ...

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 ...

PLoS Genetics, 2014 Development produces correctly patterned tissues under a wide range of conditions that alter the rate of development in the whole body. We propose two hypotheses through which tissue patterning could be coordinated with whole-body development to generate

BMP suppresses WNT to integrate patterning of orthogonal body axes in adult planarians.
PLoS Genetics, 2023 Adult regeneration restores patterning of orthogonal body axes after damage in a post-embryonic context. Planarians regenerate using distinct body-wide signals primarily regulating each axis dimension: anteroposterior Wnts, dorsoventral BMP, and ...

Spatially varying cis-regulatory divergence in Drosophila embryos elucidates cis-regulatory logic. [PDF]
PLoS Genetics, 2018 Spatial patterning of gene expression is a key process in development, yet how it evolves is still poorly understood. Both cis- and trans-acting changes could participate in complex interactions, so to isolate the cis-regulatory component of patterning ...
