This paper introduces an experimental assay to analyze eRNA transcription in Drosophila embryos using FISH and imaging, revealing eRNA dynamics and insulator effects.

The paper uses high-multiplexity imaging to show that spatial patterns in Tribolium embryos are actively reshaped during gene propagation rather than directly mapped from temporal gene expression.

The paper shows that morphogen-driven rewiring of gene regulatory networks converts temporal gene activation sequences into stable spatial patterns in insect embryos.

This paper presents a modeling framework linking molecular gene regulation to embryonic patterning, showing that a two-step enhancer integration strategy improves the robustness and evolvability of gene expression patterns.

The paper identifies enhancers in Tribolium that regulate wavelike gene expression patterns by distinguishing dynamic and static enhancers.

The paper explains how Drosophila evolved a faster, simultaneous mode of anterior-posterior patterning by switching from uniform to gradient-mediated gap gene initialization.

The paper shows that gap gene expression in Tribolium castaneum is controlled by a threshold-free Speed Regulation mechanism rather than a threshold-based French Flag model.

The paper identifies and evaluates enhancer activity in Tribolium castaneum using chromatin profiling and a cross-species reporter assay system.

The paper introduces two computational models, Speed Regulation and Gradual Enhancer Switching, to explain flexible and evolvable embryonic patterning in insects.
