Dynamic microtubules drive yolk-cytoplasm segregation in the syncytial Drosophila embryo

The paper investigates yolk-cytoplasm segregation in Drosophila embryos and identifies microtubule dynamics as the primary driver of this process.

Scaling of the Bicoid morphogen gradient: the effect of state dependent diffusion

This study proposes a model of spatially varying diffusion to explain how the Bicoid gradient scales with embryo size in Drosophila, showing that gradient scaling arises from spatial heterogeneity rather than nuclear trapping.

Electron transport chain complex I and mitochondrial fusion regulate ROS for differentiation in Drosophila neural stem cells

This study shows that complex I and mitochondrial fusion regulate ROS levels, which in turn affect differentiation in Drosophila neuroblasts.

Spatiotemporal localization and activity of mitochondria regulate actomyosin contractility in Drosophila gastrulation

This study shows that mitochondrial redistribution and activity are crucial for apical constriction in Drosophila gastrulation, regulated by the Dorsal signaling pathway.

Mitochondrial morphology dynamics and ROS regulate apical polarity and differentiation in Drosophila follicle cells

The paper shows that Drp1 regulates follicle cell differentiation in Drosophila oogenesis by controlling mitochondrial morphology, ROS levels, and epithelial polarity.

Mitochondrial fusion regulates proliferation and differentiation in the type II neuroblast lineage in Drosophila

This study shows that mitochondrial fusion regulates proliferation and differentiation in Drosophila type II neuroblast lineages through interactions with Notch signaling.

Polarity protein distribution on the metaphase furrow regulates hexagon dominated plasma membrane organization in syncytial Drosophila embryos

The paper shows that polarity protein distribution in Drosophila embryos regulates hexagon dominance in plasma membrane organization during syncytial division cycles.

Cyto-architecture constrains a photoactivation induced tubulin gradient in the syncytial Drosophila embryo

The paper uses photoactivation to study how cyto-architecture constrains the spread of cytoplasmic and tubulin molecules in Drosophila embryos, showing that tubulin gradients are more restricted by microtubules and plasma membrane structure.
