During the development of the larval Drosophila epidermis, histoblasts and epithelial cells compete for space as they grow and undergo morphological changes. This study shows that compressive forces play a key role in controlling the shape of histoblasts, leading to the buckling of their apical junctions and changing the morphology of the epidermis from straight to highly folded outlines.
My colleagues recently published a paper on #apoptosis in the #drosophila dorsal #epidermis. They have shown that two factors can predict #cell #extrusion and apoptosis. Cell size sensed by #hippo and relative cell size (compared to neighbors) sensed by #notch

💧 #Roots can bend towards water (positive #hydrotropism) and away from light (negative #phototropism).
☀️ This study examined the expression of MIZU-KUSSEI1 (#MIZ1) and GNOM/#MIZ2 in different tissues (#epidermis, #cortex, stele, root cap and #endodermis)
